Definitions
- Rho/ Rho kinase (ROCK)-dependent fibrogenic factors for example, connective tissue growth factor (CTGF) and the Hippo/ YAP signaling pathway are key downstream mediators that induce pathologic fibrosis.
- CTGF connective tissue growth factor
- YAP connective tissue growth factor
- S1P 2 receptor induces inflammatory responses, promotes vascular permeability and is induced during pathologic responses.
- CGF connective tissue growth factor
- YAP connective tissue growth factor
- S1P 2 receptor induces inflammatory responses, promotes vascular permeability and is induced during pathologic responses.
- the S1P signaling system is unique in that the ligand S1P is present abundantly in circulation during homeostatic conditions. Thus, receptor expression on the cell surface is critical for biological events such as cell migration and junction assembly.
- FIG. 1 The first FDA-approved S1P receptor inhibitor, Fingolimod/Gilenya induces irreversible receptor internalization, followed by ubiquitinylation, and protesomal degradation.
- Fingolimod belongs to a class of S1P receptor inhibitors called functional antagonists and it appears that this class of compounds work better than competitive inhibitors against the receptor.
- Fingolimod and related molecules that were designed to block lymphocyte trafficking by targeting the S1P 1 receptor do not interact with S1P 2 receptor. Thus, there is a need to develop effective inhibitors of the S1P 2 inhibitor.
- FIG. 1 is plots showing, among other things, Infarct Volume, Edema Ratio, and Neurological Deficits After Intraperitoneal Administration of compound 39120 mg/kg Twice a Day in a tMCAO Model of Male C57BL/6 Mice.
- Compounds (Vehicle [20% HPBCD], TDI-6621 120 mg/kg b.i.d.) were administered 1.3 and 9.3 hours after the onset of ischemia.
- mice were assessed for infarct size, edema ratio, and neurological deficit scoring. Infarct size corrected for edema, infarct volume, and edema ratio was calculated from TTC staining images of brains. Neurological deficits were assigned as follows (4-unable to move, 3- spontaneous circling, 2-circling when held by tail, 1-weakness in right forelimb, 0- no deficit). (*P ⁇ 0.05, **P ⁇ 0.005, Mann-Whitney test).
- FIG.2 is plots of Infarct Volume, Edema Ratio, and Neurological Deficits After Delayed Intraperitoneal Administration of compound 39120 mg/kg Twice a Day in a tMCAO Model of Male C57BL/6 Mice.
- Compounds (Vehicle [20% HPBCD], TDI-6621120 mg/kg b.i.d.) were administered 4.5 h after the onset of ischemia.
- FIG. 3 is plots showing that reatment with compound 39 significantly tprevented vascular permeability and blood brain barrier leakage in sepsis model.
- mice Male C57BL/6 mice (left) or S1PR2+/+ and S1PR2-/- mice (right) were subjected to CLP model of sepsis.
- the CLP surgery was performed on animals for 15 minutes followed by administration of compounds (vehicle, compound 3960 mg/kg IP, JTE-01330 mg/kg IP).
- Vascular permeability in the brain was calculated as RFU/g wet weight.
- Evans blue dye is injected into animals 3 hours prior to endpoint.
- the mice were transcardially perfused with cold PBS/5 mM EDTA, and the brains were harvested, weighed, and frozen. Brains were homogenized in 50% tricholoroacetic acid/PBS and incubated O/N at 4°C.
- FIG. 4 is plots showing that genetic deletion of S1pr2 prevented vascular leakage in the lung and increased survival in the mouse sepsis model.
- S1pr2 +/+ and S1pr2 -/- mice were subjected to cecal ligation and puncture (CLP) model of sepsis.
- CLP cecal ligation and puncture
- mice were transcardially perfused with cold PBS/5 mM EDTA, and lungs were harvested, weighed, and frozen. Lungs were homogenized in 50% tricholoroacetic acid/PBS and incubated O/N at 4°C. Fluorescence intensity was measured at Ex 620/ Em 680. (*P ⁇ 0.05, **P ⁇ 0.005, ****P ⁇ 0.00005, unpaired t test).

- Examples 126-127 Stroke and sepsis in vivo data Background and significance [00604] During inflammation, the vascular endothelium becomes activated, increasing permeability and coagulation. Increasing evidence indicates that sustained endothelial activation in numerous clinical settings including ischemia, sepsis and systemic inflammatory response syndrome, significantly contributes to tissue edema, perpetuates the inflammatory response, and exacerbates tissue injury ultimately resulting in organ failure and death. For instance, blood brain barrier (BBB) disruption exacerbates neuronal injury in stroke; severe endothelial dysfunction during sepsis; and systemic inflammatory response syndrome leads to increased vascular leakage and disseminated intravascular coagulation significantly contributing to multiorgan failure and death.
- BBB blood brain barrier
- S1PR2 is potently induced in cerebral microvessels during ischemia causing endothelial barrier dysfunction and exacerbation of brain injury. S1PR2 has also been demonstrated to play a critical role in vascular inflammation associated with sepsis. In the absence of S1PR2 or in the presence of JTE013-mediated inhibition of S1PR2 signaling, decreased vascular permeability is observed in response to endotoxin or polymicrobial sepsis challenge. [00605] Together these data suggest that antagonism of S1PR2 may be a useful approach for treating stroke, systemic inflammatory response syndrome, sepsis and other diseases characterized by vascular dysfunction.
- Mouse stroke model [00606] The middle cerebral artery (MCA) and branches are the most commonly affected vessels in human ischemic stroke. Techniques that occlude these vessels are thus most similar to human ischemic infarcts.

All studies were conducted in a blinded fashion. As shown in FIG.1, treatment of animals with compound 39120 mg/kg b.i.d.
- IP resulted in significant reduction of several stroke parameters including 60.7% reduction in infarct size (without edema correction), 66.7% reduction in infarct size (corrected for edema), 53.7% reduction in edema ratio, and 28.6% improvement in neurological outcomes.
- AUC 3.69 ⁇ g*h/mL
- mice were subjected to the cecal ligation and puncture (CLP) model of polymicrobial sepsis.
- CLP cecal ligation and puncture
- the CLP model for polymicrobial sepsis is the model which most closely resemble human sepsis.
- Advantages of the CLP model include the polymicrobial flora used for development of sepsis, nonrequirement for growing microbes, and the similar cytokine profile to human sepsis.
- CLP involves exposure and ligation of a portion of the cecum, followed by needle puncture and extrusion of fecal content into the body cavity. The severity of disease can be controlled by the size of needle puncture and length of cecal ligation. A rise in pro-inflammatory cytokines (including IL-6 and TNF-a) is observed after CLP.
- pro-inflammatory cytokines including IL-6 and TNF-a
- the CLP mouse model was conducted with male C57BL/6 mice treated with a single dose of vehicle (20% HPBCD/saline), JTE- 01330 mg/kg IP, or TDI-662160 mg/kg IP. The CLP surgery was conducted followed by compound administration.
- S1pr2-/- mice were subjected to polymicrobial sepsis (CLP; see Example 128), S1pr2-/- mice exhibited significantly decreased vascular leakage in the lungs (FIG.4, left panel) and improved survival (FIG.4 right panel). Therefore, genetic deletion of S1PR2 in mice results in dramatic reduction of vascular leakage (in lungs and brain) and mortality after sepsis. [00614] Together these data demonstrate that antagonism of S1PR2 is efficacious in the treatment of vascular leakage associated with sepsis.
- S1PR2 antagonists were administered after the onset of sepsis, thus, they could be used to prevent or mitigate tissue injury and multiple organ dysfunction, ultimately decreasing mortality and chronic morbidity and disabilities in sepsis survivors.
- S1PR2 is expressed in the endothelium in human tissues and upregulated during inflammation, hypoxia and ischemia, the therapeutic potential of S1PR2 antagonists is very high.
- Example 128 In vivo studies [00616] C57BL6 mice (Jax laboratories) male, 24-28g, were used for the study. Wild type and S1pr2 -/- mice were used. All animal experiments used randomization to treatment groups and blinded assessment.
- tMCAO mouse model of stroke and treatments [00617] Transient focal cerebral ischemia was induced in mice by middle cerebral artery occlusion as we have previously described (tMCAO). Thirty-three mice (male, 24-28 g, C57BL6) were used in this study. Criteria for exclusion were development of subarachnoid hemorrhage, lack of reduction of cerebral blood flow or lack of recovery after reperfusion. Surgeries, as well as all behavioral and histological assessments were performed by an investigator blinded to the drug treatment. Mice were anesthetized with 3% isoflurane vaporized in O 2 for induction and 1.5% isoflurane for maintenance.
- Temperature was maintained at 36.5 ⁇ 0.5oC, controlled by a thermostatic blanket (CMA 450 Temp Controller for mice, Harvard Apparatus, Holliston, MA) throughout the procedure.

- the left common carotid artery was exposed and the occipital artery branches of the external carotid artery (ECA) were isolated and coagulated.
- ECA occipital artery branches of the external carotid artery
- the ECA was dissected distally and coagulated along with the terminal lingual and maxillary artery branches.
- the internal carotid artery (ICA) was isolated and the extracranial branch of the ICA was then dissected.
- a rubber silicon-coated monofilament suture (Filament size 6-0, diameter 0.09-0.11 mm, length 20mm; diameter with coating 0.23 +/- 0.02 mm; coating length 5 mm, Doccol Corp., Sharon, MA) was introduced into the ECA lumen through an incision and then gently advanced approximately 9 to 9.5 mm in the ICA lumen to block MCA blood flow. For reperfusion, the suture was withdrawn 60 min after MCAO. 2-D laser speckle flowmetry (PeriCam PSI HR, Perimed, Jarfalla, Sweeden) was used to confirm MCA occlusion and reperfusion. After removal of the suture, animals randomly received an intraperitoneal injection of vehicle or compounds.
- Physiological parameters (arterial O 2 saturation, heart rate, pulse distention and respiratory rate) were recorded before, during and after tMCAO using the Mouse Ox Plus (Starr Life Sciences Corp., Oakmon, PA). After the surgery, all animals were maintained in a small animal heated recovery chamber (IMS Vetcare Chamber Recovery Unit, Harvard Apparatus, Holliston, MA). After recovery, animals were returned to their cages with free access to food and water.

Description
SMALL MOLECULE INHIBITORS OF S1P2 RECEPTOR AND USES THEREOF CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Appl. Ser. No.62/884,046, filed August 7, 2019, which is incorporated by reference as if fully set forth herein. BACKGROUND [0002] The sphingosine 1-phosphate receptor-2 (S1P2) is coupled preferentially to the heterotrimeric G13 and small GTPase Rho pathway. It is induced during pathological conditions in fibrogenic, immune and vascular cells. Activation of this pathway in fibroblasts induces the Rho/ Rho kinase (ROCK)- dependent fibrogenic factors, for example, connective tissue growth factor (CTGF) and the Hippo/ YAP signaling pathway are key downstream mediators that induce pathologic fibrosis. In vascular endothelial cells, the S1P2 receptor induces inflammatory responses, promotes vascular permeability and is induced during pathologic responses. Thus, it is thought to be one of the key drivers of tissue injury, fibrosis, and pathologic angiogenesis. [0003] The S1P signaling system is unique in that the ligand S1P is present abundantly in circulation during homeostatic conditions. Thus, receptor expression on the cell surface is critical for biological events such as cell migration and junction assembly. The first FDA-approved S1P receptor inhibitor, Fingolimod/Gilenya induces irreversible receptor internalization, followed by ubiquitinylation, and protesomal degradation. Fingolimod belongs to a class of S1P receptor inhibitors called functional antagonists and it appears that this class of compounds work better than competitive inhibitors against the receptor. However, Fingolimod and related molecules that were designed to block lymphocyte trafficking by targeting the S1P1 receptor do not interact with S1P2 receptor. Thus, there is a need to develop effective inhibitors of the S1P2 inhibitor. BRIEF DESCRIPTION OF THE FIGURES [0004] The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed herein. [0005] FIG. 1 is plots showing, among other things, Infarct Volume, Edema Ratio, and Neurological Deficits After Intraperitoneal Administration of compound 39120 mg/kg Twice a Day in a tMCAO Model of Male C57BL/6 Mice. Male C57BL/6J mice, 10-11 weeks old, were subjected to intra-arterial suture occlusion of the middle cerebral artery (MCAO) for 60 minutes followed by reperfusion. Compounds (Vehicle [20% HPBCD], TDI-6621 120 mg/kg b.i.d.)
were administered 1.3 and 9.3 hours after the onset of ischemia. Twenty-four hours after the start of tMCAO surgery, mice were assessed for infarct size, edema ratio, and neurological deficit scoring. Infarct size corrected for edema, infarct volume, and edema ratio was calculated from TTC staining images of brains. Neurological deficits were assigned as follows (4-unable to move, 3- spontaneous circling, 2-circling when held by tail, 1-weakness in right forelimb, 0- no deficit). (*P<0.05, **P<0.005, Mann-Whitney test). [0006] FIG.2 is plots of Infarct Volume, Edema Ratio, and Neurological Deficits After Delayed Intraperitoneal Administration of compound 39120 mg/kg Twice a Day in a tMCAO Model of Male C57BL/6 Mice. Male C57BL/6J mice, 10- 11 weeks old, were subjected to intra-arterial suture occlusion of the middle cerebral artery (MCAO) for 60 minutes followed by reperfusion. Compounds (Vehicle [20% HPBCD], TDI-6621120 mg/kg b.i.d.) were administered 4.5 h after the onset of ischemia. Twenty-four hours after the start of tMCAO surgery, mice were assessed for infarct size, edema ratio, and neurological deficit scoring. Infarct size corrected for edema, infarct volume, and edema ratio was calculated from TTC staining images of brains. Neurological deficits were assigned as follows (4-unable to move, 3-spontaneous circling, 2-circling when held by tail, 1-weakness in right forelimb, 0-no deficit). (*P<0.05, **P<0.005).

Vascular permeability in the brain was calculated as RFU/g wet weight. Evans blue dye is injected into animals 3 hours prior to endpoint. At endpoint 7.5 hours after drug administration, the mice were transcardially perfused with cold PBS/5 mM EDTA, and the brains were harvested, weighed, and frozen. Brains were homogenized in 50% tricholoroacetic acid/PBS and incubated O/N at 4°C. Fluorescence intensity was measured at Ex 620/ Em 680. (*P<0.05, **P<0.005, ****P<0.00005). [0008] FIG. 4 is plots showing that genetic deletion of S1pr2 prevented vascular leakage in the lung and increased survival in the mouse sepsis model. S1pr2+/+ and S1pr2-/- mice were subjected to cecal ligation and puncture (CLP) model of sepsis. Left: Vascular permeability in the lungs was calculated as RFU/g wet weight.

For example, the compound can have the structure of Formula (1) and Formula (A) or the compound can have the structure of Formula (1) and Formula (M). [0052] Compounds of the Formulae (1)-(3) and (A)-(M) exhibit sphingosine 1-phosphate receptor 2 (S1P2) agonisitc activity. In some examples, compounds of the Formulae (1)-(3) and (A)-(M) exhibit S1P2 agonistic activity at concentrations of from about 100 nM to about 100 mM (e.g., from about 100 nM to about 10 mM; about 100 nM to about 900 nM; about 250 nM to about 1 mM; or about 750 nM to about 100 mM). [0053] The present invention also provides a pharmaceutical composition comprising a compound of any of the preceding formulae and a pharmaceutically acceptable carrier. The present invention also provides a pharmaceutical composition comprising a therapeutically effective amount of a compound of one of Formulae (1)-(3) and (A)-(M), and a pharmaceutically acceptable carrier. [0054] Pharmaceutical compositions contemplated herein are those comprising one or more compounds of the various embodiments of the present invention and one or more pharmaceutically acceptable excipients. A “pharmaceutical composition” refers to a chemical or biological composition suitable for administration to a subject (e.g., mammal). Such compositions can be specifically formulated for administration via one or more of a number of routes, including but not limited to buccal, cutaneous, epicutaneous, epidural, infusion, inhalation, intraarterial, intracardial, intracerebroventricular, intradermal, intramuscular, intranasal, intraocular, intraperitoneal, intraspinal, intrathecal, intravenous, oral, parenteral, pulmonary, rectally via an enema or suppository,
subcutaneous, subdermal, sublingual, transdermal, and transmucosal. In addition, administration can by means of capsule, drops, foams, gel, gum, injection, liquid, patch, pill, porous pouch, powder, tablet, or other suitable means of administration. [0055] A “pharmaceutical excipient” or a “pharmaceutically acceptable excipient” is a carrier, sometimes a liquid, in which an active therapeutic agent is formulated. The excipient generally does not provide any pharmacological activity to the formulation, though it can provide chemical and/or biological stability, and release characteristics. Examples of suitable formulations can be found, for example, in Remington, The Science And Practice of Pharmacy, 20th Edition, (Gennaro, A. R., Chief Editor), Philadelphia College of Pharmacy and Science, 2000, which is incorporated by reference in its entirety. [0056] As used herein “pharmaceutically acceptable carrier” or “excipient” includes, but is not limited to, any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents that are physiologically compatible. In one embodiment, the carrier is suitable for parenteral administration. Alternatively, the carrier can be suitable for intravenous, intraperitoneal, intramuscular, sublingual, or oral administration. Pharmaceutically acceptable carriers include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active compound, use thereof in the pharmaceutical compositions of the invention is contemplated. Supplementary active compounds can also be incorporated into the compositions. [0057] Pharmaceutical compositions can be sterile and stable under the conditions of manufacture and storage. The composition can be formulated as a solution, microemulsion, liposome, or other ordered structure suitable to high drug concentration. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol, and liquid polyethylene glycol), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. [0058] In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol, sorbitol, or sodium chloride in
the composition. Prolonged absorption of injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, monostearate salts and gelatin. Moreover, the compounds described herein can be formulated in a time release formulation, for example in a composition that includes a slow release polymer. The active compounds can be prepared with carriers that will protect the compound against rapid release, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, polylactic acid and polylactic, polyglycolic copolymers (PLG). Many methods for the preparation of such formulations are known to those skilled in the art. [0059] Oral forms of administration are also contemplated herein. The pharmaceutical compositions of the present invention can be orally administered as a capsule (hard or soft), tablet (film coated, enteric coated or uncoated), powder or granules (coated or uncoated) or liquid (solution or suspension). The formulations can be conveniently prepared by any of the methods well-known in the art. The pharmaceutical compositions of the present invention can include one or more suitable production aids or excipients including fillers, binders, disintegrants, lubricants, diluents, flow agents, buffering agents, moistening agents, preservatives, colorants, sweeteners, flavors, and pharmaceutically compatible carriers. [0060] For each of the recited embodiments, the compounds can be administered by a variety of dosage forms as known in the art. Any biologically- acceptable dosage form known to persons of ordinary skill in the art, and combinations thereof, are contemplated. Examples of such dosage forms include, without limitation, chewable tablets, quick dissolve tablets, effervescent tablets, reconstitutable powders, elixirs, liquids, solutions, suspensions, emulsions, tablets, multi-layer tablets, bi-layer tablets, capsules, soft gelatin capsules, hard gelatin capsules, caplets, lozenges, chewable lozenges, beads, powders, gum, granules, particles, microparticles, dispersible granules, cachets, douches, suppositories, creams, topicals, inhalants, aerosol inhalants, patches, particle inhalants, implants, depot implants, ingestibles, injectables (including subcutaneous, intramuscular, intravenous, and intradermal), infusions, and combinations thereof. [0061] Other compounds which can be included by admixture are, for example, medically inert ingredients (e.g., solid and liquid diluent), such as
lactose, dextrose-saccharose, cellulose, starch or calcium phosphate for tablets or capsules, olive oil or ethyl oleate for soft capsules and water or vegetable oil for suspensions or emulsions; lubricating agents such as silica, talc, stearic acid, magnesium or calcium stearate and/or polyethylene glycols; gelling agents such as colloidal clays; thickening agents such as gum tragacanth or sodium alginate, binding agents such as starches, arabic gums, gelatin, methylcellulose, carboxymethylcellulose or polyvinylpyrrolidone; disintegrating agents such as starch, alginic acid, alginates or sodium starch glycolate; effervescing mixtures; dyestuff; sweeteners; wetting agents such as lecithin, polysorbates or laurylsulphates; and other therapeutically acceptable accessory ingredients, such as humectants, preservatives, buffers and antioxidants, which are known additives for such formulations. [0062] Liquid dispersions for oral administration can be syrups, emulsions, solutions, or suspensions. The syrups can contain as a carrier, for example, saccharose or saccharose with glycerol and/or mannitol and/or sorbitol. The suspensions and the emulsions can contain a carrier, for example a natural gum, agar, sodium alginate, pectin, methylcellulose, carboxymethylcellulose, or polyvinyl alcohol. [0063] The amount of active compound in a therapeutic composition according to various embodiments of the present invention can vary according to factors such as the disease state, age, gender, weight, patient history, risk factors, predisposition to disease, administration route, pre-existing treatment regime (e.g., possible interactions with other medications), and weight of the subject. Dosage regimens can be adjusted to provide the optimum therapeutic response. For example, a single bolus can be administered, several divided doses can be administered over time, or the dose can be proportionally reduced or increased as indicated by the exigencies of therapeutic situation. [0064] A “dosage unit form,” as used herein, refers to physically discrete units suited as unitary dosages for the mammalian subjects to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the invention are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and the limitations inherent in the art of compounding such an active compound for the treatment of sensitivity in subjects. In therapeutic use for treatment of conditions in mammals (e.g., humans) for which the compounds of the present invention or
an appropriate pharmaceutical composition thereof are effective, the compounds of the present invention can be administered in an effective amount. The dosages as suitable for this invention can be a composition, a pharmaceutical composition or any other compositions described herein. [0065] For each of the recited embodiments, the dosage is typically administered once, twice, or thrice a day, although more frequent dosing intervals are possible. The dosage can be administered every day, every 2 days, every 3 days, every 4 days, every 5 days, every 6 days, and/or every 7 days (once a week). In one embodiment, the dosage can be administered daily for up to and including 30 days, preferably between 7-10 days. In another embodiment, the dosage can be administered twice a day for 10 days. If the patient requires treatment for a chronic disease or condition, the dosage can be administered for as long as signs and/or symptoms persist. The patient can require "maintenance treatment" where the patient is receiving dosages every day for months, years, or the remainder of their lives. In addition, the composition of this invention can be to effect prophylaxis of recurring symptoms. For example, the dosage can be administered once or twice a day to prevent the onset of symptoms in patients at risk, especially for asymptomatic patients. [0066] The compositions described herein can be administered in any of the following routes: buccal, epicutaneous, epidural, infusion, inhalation, intraarterial, intracardial, intracerebroventricular, intradermal, intramuscular, intranasal, intraocular, intraperitoneal, intraspinal, intrathecal, intravenous, oral, parenteral, pulmonary, rectally via an enema or suppository, subcutaneous, subdermal, sublingual, transdermal, and transmucosal. The preferred routes of administration are buccal and oral. The administration can be local, where the composition is administered directly, close to, in the locality, near, at, about, or in the vicinity of, the site(s) of disease, e.g., inflammation, or systemic, wherein the composition is given to the patient and passes through the body widely, thereby reaching the site(s) of disease. Local administration can be administration to, for example, tissue, organ, and/or organ system, which encompasses and/or is affected by the disease, and/or where the disease signs and/or symptoms are active or are likely to occur. Administration can be topical with a local effect, composition is applied directly where its action is desired. Administration can be enteral wherein the desired effect is systemic (non-local), composition is given via the digestive tract. Administration can be parenteral, where the desired effect is systemic, composition is given by other routes than the digestive tract.
[0067] The present disclosure also provides a method for treating a fibrotic disease, abnormal vascular leak and pathological angiogenesis, and tumor-associated angiogenesis comprising administering a therapeutically effective amount of any of the preceding compounds, e.g., a compound of any of Formulae (1)-(3) and (A)-(M), or a pharmaceutical composition comprising said compound, to a subject in need thereof. In various embodiments, the abnormal vascular leak and pathological angiogenesis is associated with the wet form of age-related macular degeneration. In various embodiments, the fibrotic disease is fibrosis of the lung, liver, kidney, retina, skin or heart. [0068] The present disclosure also provides a method for treating multiple sclerosis comprising administering a therapeutically effective amount of any of the preceding compounds, e.g., a compound of any of Formulae (1)-(3) and (A)- (M), or a pharmaceutical composition comprising said compound, to a subject in need thereof.

[0070] The present disclosure also provides a method for chimeric antigen receptor T-cell (CAR-T) therapy, comprising administering a therapeutically effective amount of any of the preceding compounds, e.g., a compound of any of Formulae (1)-(3) and (A)-(M), or a pharmaceutical composition comprising said compound, to the subject. CAR-T therapy represents an emerging breakthrough in oncology with rapidly increasing uptake by clinicians due to its promise for patients. Unfortunately, CAR-T can be associated with significant toxicity, sequelae from treatment-related inflammation and leaky vessels, including cytokine release syndrome (CRS; 50%-100% of patients) and/or neurologic side effects (10%-50% of patients). These side effects often prove fatal, limiting the potential utility of CAR-T and many of the drugs currently used to manage the CRS side effects significantly reduce CAR-T efficacy. Compounds described herein may have an advantage of abrogating this significant CAR-T risk without eliminating its effectiveness. Without being limited by theory, compounds described herein may provide such advantages by merit of protecting the blood-brain barrier from vascular leakage.

[0084] Three coronaviruses have crossed the species barrier to cause deadly pneumonia in humans since the beginning of the 21st century: severe acute respiratory syndrome coronavirus (SARS-CoV), Middle-East respiratory syndrome coronavirus, and SARS-CoV-2. SARS-CoV emerged in the Guangdong province of China in 2002 and spread to five continents through air travel routes, infecting 8,098 people and causing 774 deaths. In 2012, MERS- CoV emerged in the Arabian Peninsula, where it remains a major public health concern, and was exported to 27 countries, infecting a total of 2,494 individuals and claiming 858 lives. A previously unknown coronavirus, named SARS-CoV-2, was discovered in December 2019 in Wuhan, Hubei province of China and was sequenced and isolated by January 2020 SARSCoV-2 is associated with an ongoing outbreak of atypical pneumonia (Covid-2019) that has affected over 400,000 people and killed more than 10,000 of those affected in >60 countries as of March 26, 2020. [0085] On January 30, 2020, the World Health Organization declared the SARS-CoV-2 epidemic a public health emergency of international concern. MERS-CoV was suggested to originate from bats, but the reservoir host fueling spillover to humans is unequivocally dromedary camels. Both SARS-CoV and SARS-CoV-2 are closely related and originated in bats, who most likely serve as reservoir host for these two viruses. Whereas palm civets and racoon dogs have been recognized as intermediate hosts for zoonotic transmission of SARS-CoV between bats and humans, the SARS-CoV-2 intermediate host remains
unknown. The recurrent spillovers of coronaviruses in humans along with detection of numerous coronaviruses in bats, including many SARS-related coronaviruses (SARSr-CoVs), suggest that future zoonotic transmission events may continue . In addition to the highly pathogenic zoonotic pathogens SARS- CoV, MERS-CoV, and SARS-CoV-2, all belonging to the b-coronavirus genus, four low-pathogenicity coronaviruses are endemic in humans: HCoV-OC43, HCoVHKU1, HCoV-NL63, and HCoV-229E. [0086] Accordingly, the present disclosure also provides a method of treating and preventing conditions caused by one or more coronaviruses, including SARS-CoV-2 (COVID-19), characterized by at least one of acute lung injury, vascular leakage, endothelial inflammation (endotheliitis), disseminated intravascular coagulation and systemic vascular dysfunction leading to at least one of hypoxia, ischemia, multiple organ failure (kidney, heart, liver and brain injury), coma, and death, the method comprising administering a therapeutically effective amount of any of the preceding compounds, e.g., a compound of any of Formulae (1)-(3) and (A)-(M), or a pharmaceutical composition comprising said compound, to a subject in need thereof. [0087] The present disclosure also provides a method of treating and preventing chronic complications of coronavirus-associated dieseases (e.g., COVID-19), including lung, kidney, heart and liver chronic dysfunction and central nervous system pathologies such as depression, anxiety, cognitive decline and accelerated dementia, the method comprising administering a therapeutically effective amount of any of the preceding compounds, e.g., a compound of any of Formulae (1)-(3) and (A)-(M), or a pharmaceutical composition comprising said compound, to a subject in need thereof. [0088] The present disclosure also provides a method of treating and preventing conditions caused by one or more viruses characterized by at least one of vascular leakage and endothelial inflammation (endotheliitis), the method comprising administering a therapeutically effective amount of any of the preceding compounds, e.g., a compound of any of Formulae (1)-(3) and (A)-(M), or a pharmaceutical composition comprising said compound, to a subject in need thereof. Such viruses include, but are not limited to the Filoviridae family of viruses and the Flaviviridae family of viruses. [0089] Two members of the Filoviridae family have been identified: EBOV and MARV. Two key pathogenic types of the Filoviridae family have been identified: Ebolavirus and MARV. There is one identified variant of MARV and five identified species of ebolavirus: Zaire (e.g., Ebola virus, EBOV), Sudan, Tai
Forest, Bundibugyo, and Reston. The exact origin, locations, and natural habitat of Filoviridae are unknown. However, because of available evidence and the nature of similar viruses, it is postulated that Filoviridae are zoonotic (i.e., animal- borne) and are normally maintained in an animal host that is native to the African continent. [0090] The Ebola virus genus includes five known species: (1) Bundibugyo ebolavirus, also known as Bundibugyo virus (BDBV, previously BEBOV); (2) Reston ebolavirus, also known as Reston virus or Ebola-Reston (RESTV, previously REBOV); (3) Sudan ebolavirus, also known as Sudan virus or Ebola-Sudan (SUDV, previously SEBOV); (4) Tai Forest ebolavirus, also known as Tai Forest virus or Ebola-Tai (TAFV, previously CIEBOV); and (5) Zaire ebolavirus, also known as Ebola virus or Ebola-Zaire (EBOV, previously ZEBOV). [0091] The Marburg virus genus includes the species Marburg marburgvirus, also known as Marburg virus (MARV) or Ravn virus (RAVV). The Cuevavirus genus includes the species Lloviu cuevavirus, also known as the Lloviu virus (LLOV). [0092] Viruses included in the Flaviviridae family include at least three distinguishable genera including pestiviruses, flaviviruses, and hepaciviruses (Calisher, et al., J. Gen. Virol., 1993, 70, 37-43). While pestiviruses cause many economically important animal diseases such as bovine viral diarrhea virus (BVDV), classical swine fever virus (CSFV, hog cholera) and border disease of sheep (BDV), their importance in human disease is less well characterized (Moennig, V., et al., Adv. Vir. Res.1992, 48, 53-98). Flaviviruses are responsible for important human diseases such as dengue fever and yellow fever while hepaciviruses cause hepatitis C virus infections in humans. Other important viral infections caused by the Flaviviridae family include West Nile virus (WNV) Japanese encephalitis virus (JEV), tick-borne encephalitis virus, Junjin virus, Murray Valley encephalitis, St Louis enchaplitis, Omsk hemorrhagic fever virus and Zika virus. Combined, infections from the Flaviviridae virus family cause significant mortality, morbidity and economic losses throughout the world. Therefore, there is a need to develop effective treatments for Flaviviridae virus infections. [0093] The hepatitis C virus (HCV) is the leading cause of chronic liver disease worldwide (Boyer, N. et al. J Hepatol.32:98-112, 2000) so a significant focus of current antiviral research is directed toward the development of improved methods of treatment of chronic HCV infections in humans (Di Besceglie, A. M. and Bacon, B. R., Scientific American, October: 80-85, (1999); Gordon, C. P., et
al., J. Med. Chem.2005, 48, 1-20; Maradpour, D.; et al., Nat. Rev. Micro.2007, 5(6), 453-463). A number of HCV treatments are reviewed by Bymock et al. in Antiviral Chemistry & Chemotherapy, 11:2; 79-95 (2000). [0094] Various compounds disclosed herein have ^-arrestin-determined IC50 values of less than 1 mM, less than 500 nM, less than 200 nM, less than 100 nM, less than 60 nM, less than 50 nM, less than 40 nM, less than 30 nM, less than 20 nM or less than 10 nM; for example, ^-arrestin-determined IC50 values IC50 values of from about 1 nM to about 100 nM, about 1 nM to about 10 nM, about 1 nM to about 5 nM, about 100 nM to about 1 mM, about 1 mM to about 5 mM or between about 5 mM and 10 mM. [0095] The term “therapeutically effective amount” as used herein, refers to that amount of one or more compounds of the various examples of the present invention that elicits a biological or medicinal response in a tissue system, animal or human, that is being sought by a researcher, veterinarian, medical doctor or other clinician, which includes alleviation of the symptoms of the disease or disorder being treated. In some examples, the therapeutically effective amount is that which can treat or alleviate the disease or symptoms of the disease at a reasonable benefit/risk ratio applicable to any medical treatment. However, it is to be understood that the total daily usage of the compounds and compositions described herein can be decided by the attending physician within the scope of sound medical judgment. The specific therapeutically-effective dose level for any particular patient will depend upon a variety of factors, including the condition being treated and the severity of the condition; activity of the specific compound employed; the specific composition employed; the age, body weight, general health, gender and diet of the patient: the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidentally with the specific compound employed; and like factors well known to the researcher, veterinarian, medical doctor or other clinician. It is also appreciated that the therapeutically effective amount can be selected with reference to any toxicity, or other undesirable side effect, that might occur during administration of one or more of the compounds described herein.

[00121] In some instances, the compounds described herein (e.g., the compounds of the Formulae (1)-(3) and (A)-(M) can contain chiral centers. All diastereomers of the compounds described herein are contemplated herein, as well as racemates. [00122] As used herein, the term “salts” and “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic groups such as amines; and alkali or organic salts of acidic groups such as carboxylic acids. Pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent
compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, and nitric; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2- acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, and isethionic, and the like. [00123] Pharmaceutically acceptable salts can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. In some instances, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric (or larger) amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington’s Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, the disclosure of which is hereby incorporated by reference. [00124] The term “solvate” means a compound, or a salt thereof, that further includes a stoichiometric or non-stoichiometric amount of solvent bound by non-covalent intermolecular forces. Where the solvent is water, the solvate is a hydrate. [00125] The term “prodrug” means a derivative of a compound that can hydrolyze, oxidize, or otherwise react under biological conditions (in vitro or in vivo) to provide an active compound, particularly a compound of the invention. Examples of prodrugs include, but are not limited to, derivatives and metabolites of a compound of the invention that include biohydrolyzable moieties such as biohydrolyzable amides, biohydrolyzable esters, biohydrolyzable carbamates, biohydrolyzable carbonates, biohydrolyzable ureides, and biohydrolyzable phosphate analogues. Specific prodrugs of compounds with carboxyl functional groups are the lower alkyl esters of the carboxylic acid. The carboxylate esters are conveniently formed by esterifying any of the carboxylic acid moieties present on the molecule. Prodrugs can typically be prepared using well-known methods, such as those described by Burger’s Medicinal Chemistry and Drug Discovery 6th ed. (Donald J. Abraham ed., 2001, Wiley) and Design and Application of Prodrugs (H. Bundgaard ed., 1985, Harwood Academic Publishers GmbH). [00126] As used herein, the term “subject” or “patient” refers to any organism to which a composition described herein can be administered, e.g., for
experimental, diagnostic, prophylactic and/or therapeutic purposes. Subject refers to a mammal receiving the compositions disclosed herein or subject to disclosed methods. It is understood and herein contemplated that “mammal” includes but is not limited to humans, non-human primates, cows, horses, dogs, cats, mice, rats, rabbits, and guinea pigs. [00127] Values expressed in a range format should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub- ranges encompassed within that range as if each numerical value and sub-range were explicitly recited. For example, a range of “about 0.1% to about 5%” or “about 0.1% to 5%” should be interpreted to include not just about 0.1% to about 5%, but also the individual values (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%) within the indicated range. The statement “about X to Y” has the same meaning as “about X to about Y,” unless indicated otherwise. Likewise, the statement “about X, Y, or about Z” has the same meaning as “about X, about Y, or about Z,” unless indicated otherwise. [00128] In this document, the terms “a,” “an,” or “the” are used to include one or more than one unless the context clearly dictates otherwise. The term “or” is used to refer to a nonexclusive “or” unless otherwise indicated. In addition, it is to be understood that the phraseology or terminology employed herein, and not otherwise defined, is for the purpose of description only and not of limitation. Any use of section headings is intended to aid reading of the document and is not to be interpreted as limiting. Further, information that is relevant to a section heading can occur within or outside of that particular section. Furthermore, all publications, patents, and patent documents referred to in this document are incorporated by reference herein in their entirety, as though individually incorporated by reference. In the event of inconsistent usages between this document and those documents so incorporated by reference, the usage in the incorporated reference should be considered supplementary to that of this document; for irreconcilable inconsistencies, the usage in this document controls. [00129] In the methods described herein, the steps can be carried out in any order without departing from the principles of the invention, except when a temporal or operational sequence is explicitly recited. Furthermore, specified steps can be carried out concurrently unless explicit claim language recites that they be carried out separately. For example, a claimed step of doing X and a claimed step of doing Y can be conducted simultaneously within a single
operation, and the resulting process will fall within the literal scope of the claimed process. [00130] The term “about” as used herein can allow for a degree of variability in a value or range, for example, within 10%, within 5%, or within 1% of a stated value or of a stated limit of a range. [00131] Each embodiment described above is envisaged to be applicable in each combination with other embodiments described herein. For example, embodiments corresponding to Formula (I) are equally envisaged as being applicable to Formulae (A)-(M). [00132] The terms and expressions that have been employed are used as terms of description and not of limitation, and there is no intention in the use of such terms and expressions of excluding any equivalents of the features shown and described or portions thereof, but it is recognized that various modifications are possible within the scope of the embodiments of the present disclosure.

Examples [00134] The present invention can be better understood by reference to the following examples which are offered by way of illustration. The present invention is not limited to the examples given herein. Biological methods b-Arrestin assay [00135] CHO (Chinese Hamster Ovary) cells stably expressing mEDG5 (mouse-S1PR2) receptor based on enzyme fragment complementation technology were purchased from Discover X, USA and cultured according to the manufacturer’s instruction. b-Arrestin assay was performed using this stable cell line to determine the IC50 value of the compounds with minor modifications in
manufacturer’s instruction. Briefly, 1 x 104 cells/well reconstituted in a final volume of 100µl of cell plating reagent were plated into a 96 well white clear bottom plate (CorningTM CostarTM , USA) and incubated 16 h at 37 °C in a humidified 95 % air and 5 % CO2 incubator. Compounds were diluted in 0.4 % fatty acid free BSA (Sigma Aldrich, USA) prepared in 1XPBS, pH7.4 (GIBCO). Plated cells were first pretreated with the compounds for 30 min. Thereafter, pretreated cells were exposed to 5µl of agonist treatment i.e, Sphingosine1- phosphate(S1P) (Enzo Lifescience, USA) at EC80 concentration and incubated for 90 min under normal incubation conditions. Then, 55 µL of substrate solution was added to each well of the assay plate and incubated further for 60 min in dark at room temperature. Thereafter, the intensity of luminescence was measured using a luminometer (Promega,USA). The IC50 value for each of the compounds with antagonist activity was calculated using the appropriate statistical parameters in Prism/Graphpad7. Functional assay: E-Selectin assay and Dextran leakage assay 1) E-Selectin assay Cell culture and treatment [00136] The mouse brain endothelial cell line, bEnd.3 was obtained from ATCC and cultured in Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10 % fetal bovine serum (ATCC), 1x GlutaMax (GIBCO, USA), and 100 U/ml penicillin/streptomycin (GIBCO, USA) at 37 °C in a humidified 95 % air and 5 % CO2 incubator. For the assay, 5X104 cells were seeded in a final volume of 250µl of complete DMEM in each well of a 48 well plate and allowed to grow until 80% confluency. Then complete media was replenished with serum-deprived DMEM culture media and allowed to equilibrate for 3hours prior to treatments. Then cells (in serum starved condition) were first pre-treated with indicated concentrations of JTE-013 (Cayman Chemical Co., USA):
or, synthesized compounds diluted in 0.4 % fatty acid free BSA (Millipore-Sigma) prepared in 1XPBS, pH7.4 (GIBCO, USA) independently for 30 min and incubated under normal culture conditions. Thereafter, pre-treated cells were
exposed to 2 ng/ml of recombinant muTNF-a (R&D Systems, USA) for 6 h under normal culture conditions. Finally, cells were harvested for total RNA isolation. RNA isolation [00137] First, cells were gently rinsed with ice-cold PBS on ice twice after the treatment to remove media and debris. Then 100µl of lysis buffer reagent (Qiagen, Germany) was added to each well and incubated for 3 min at room temperature. Thereafter, RNA was extracted from the total cell lysate with RNeasy Kit (QIAGEN, Germany) constituting on-column DNAseI digestion according to the manufacturer’s instruction. Finally, the concentration of extracted total RNA from respective samples were measured with VarioskanTM Multimode plate reader (Thermo Scientific, USA) and RNA preps were processed for cDNA synthesis. Reverse transcription of RNA and quantitative real-time (qRT) PCR 100 ng of total RNA was used as template to prepare cDNA for each sample in the presence of Verso-Reverse Transcriptase and Random Hexamer Primers (Thermo Scientific, USA) at 42 °C for 30 min in a final reaction volume of 20µl. Then, the cDNA prep was diluted 5-fold with nuclease free water to obtain a final volume of 100µl. SYBR Green chemistry with Rox dye signal normalization (Quanta bio, MA, USA) -based quantitative PCR was performed to quantify the expression of mouse specific pro-inflammatory gene E-selectin with primers (Forward: CCGTCCCTTGGTAGTTGCA, Reverse: CAAGTAGAGCAATGAGGACGATGT) and housekeeping control 18srRNA using primers (Forward: ACCTCTCGAAGTGTTGGATACAG, Reverse: TTCACTAATGACACAAACGTGATTC). qPCR reactions were run in triplicates on a 96 well plate with 2µl of cDNA as template in a final reaction volume of 10µl per well for each sample. Finally, the plate was loaded on to the ABI-7500 Sequence Detection System PCR machine (Applied Biosystems, USA) as per manufacturer’s instructions. The expression levels (Ct values) of E-selectin were normalized to expression levels of 18s rRNA as DCt values. For samples and controls, the relative expression levels of E-selectin were expressed as 2-D Ct values by comparing the DCt values of TNF-alpha treated control to the compound+TNF-alpha treated samples. Fold change in E-selectin expression was calculated by comparing the 2-D Ct values of the treated sample with that of respective experimental control. 2) Dextran leakage assay [00138] bEND3 cells were grown on the Transwell Multiple Well Plate with Permeable Polyester Membrane Inserts, pore size 0.4 mM, culture area 0.33cm2
(Corning, USA) coated with 50 ^g/ml of fibronectin (EMD Millipore, USA). Upon confluency, cells plated in the insert (upper chamber) were treated with appropriate concentrations of the compounds (at a final volume of 5 ml) prepared in 0.4% fatty acid free BSA (Sigma Aldrich, USA) or, complete DMEM media. Thereafter, cells were incubated for 30 min followed by treatment of 10 ng/ml of recombinant muTNF-a (R&D Systems) for 6hrs. To assess the leakage of the endothelial cells, of conjugated 4.4 kDa Tetramethylrhodamine Isothiocyanate (TMR)-Dextran (Sigma Aldrich, USA) dissolved in 5 ml of serum free medium to give a final concentration of 100mg/ml was added to each insert with compound treated cells and incubated for 1 hr at 37 °C in dark. The protective effects of the compounds were assessed based on the leakage of dextran from the upper chamber to the lower chamber containing complete media of each well. The fluorescence intensity was measured at Ex550nm/Em570nm with a fluorescence reader (SpectraMax M2, Molecular Devices) by taking 100 ml of medium from the lower chamber. Biological data

Examples 126-127: Stroke and sepsis in vivo data Background and significance [00604] During inflammation, the vascular endothelium becomes activated, increasing permeability and coagulation. Increasing evidence indicates that sustained endothelial activation in numerous clinical settings including ischemia, sepsis and systemic inflammatory response syndrome, significantly contributes to tissue edema, perpetuates the inflammatory response, and exacerbates tissue injury ultimately resulting in organ failure and death. For instance, blood brain barrier (BBB) disruption exacerbates neuronal injury in stroke; severe endothelial dysfunction during sepsis; and systemic inflammatory response syndrome leads to increased vascular leakage and disseminated intravascular coagulation significantly contributing to multiorgan failure and death. However, no therapies specifically targeting the endothelium are yet available. Instead, non-specific therapies are used in clinical practice. Although these treatments have failed to significantly improve outcomes, they are still used due to the lack of alternative therapies. Several lines of evidence point to a role for S1PR2 in endothelial dysfunction and in the pathophysiology of these diseases. S1PR2 null mice subjected to ischemic stroke show a dramatic decrease in infarct ratio and total edema compared with WT mice. Treatment of the mice with the
S1PR2 antagonist JTE013 after stroke also resulted in a dramatic decrease in infarct ratio and edema as well as improved neurological outcomes. S1PR2 is potently induced in cerebral microvessels during ischemia causing endothelial barrier dysfunction and exacerbation of brain injury. S1PR2 has also been demonstrated to play a critical role in vascular inflammation associated with sepsis. In the absence of S1PR2 or in the presence of JTE013-mediated inhibition of S1PR2 signaling, decreased vascular permeability is observed in response to endotoxin or polymicrobial sepsis challenge. [00605] Together these data suggest that antagonism of S1PR2 may be a useful approach for treating stroke, systemic inflammatory response syndrome, sepsis and other diseases characterized by vascular dysfunction. The pathophysiological relevance of these findings is strengthened by the expression of S1PR2 in the endothelium of several organs, including brain and its upregulation in human stroke. Mouse stroke model [00606] The middle cerebral artery (MCA) and branches are the most commonly affected vessels in human ischemic stroke. Techniques that occlude these vessels are thus most similar to human ischemic infarcts. Among these models, the intra-arterial suture occlusion of the MCA (tMCAO) is the most common. This model is less invasive and involves temporary occlusion for a specific duration. This model has several advantages. It closely mimics human ischemic stroke, the large infarct size is reproducible, it is highly controllable by reperfusion, and the procedure is relatively simple to perform. [00607] To evaluate the efficacy of the compounds described herein in treating injury associated with I/R, mice were subjected to several studies using the mouse tMCAO model. Animals were treated with either positive control S1PR2 antagonist JTE-013 or the compounds as described herein. All studies were conducted in a blinded fashion. As shown in FIG.1, treatment of animals with compound 39120 mg/kg b.i.d. IP resulted in significant reduction of several stroke parameters including 60.7% reduction in infarct size (without edema correction), 66.7% reduction in infarct size (corrected for edema), 53.7% reduction in edema ratio, and 28.6% improvement in neurological outcomes. PK- PD correlation studies indicated that maximum protection correlates with plasma Cmax=843 nM (free plasma protein concentration) and an exposure of 3.69µg*h/mL (AUC) (not shown). [00608] In order to test the efficacy of a delayed administration of compound 39 instead of dosing compound 39 one-hour post-ischemia as was
done previously, compounds were administered 4.5 hours after the onset of stroke. The administration of compound 39 4.5 h after the onset of ischemia significantly decreased infarct size, edema ratio (~50% protection) and improved neurological outcomes at 24 hours (FIG.2). [00609] Together, these studies demonstrate that treatment of male C57BL/6J mice with compound 39 after ischemic stroke significantly ameliorates brain injury and improves neurological outcomes. The therapeutic time window of administration of the S1PR2 antagonist after the onset of stroke is at least 4.5 hours. Since endothelial dysfunction is also the cause of stroke and other ischemic diseases, S1PR2 antagonists can also be used for preventive treatment. [00610] Given that S1PR2 is expressed in the endothelium of several organs in humans, including brain and it is upregulated in human stroke, the therapeutic potential of S1PR2 antagonists is very high. Mouse Sepsis Model [00611] To address the utility of the compounds described herein in treating vascular leakage associated with septic challenge, mice were subjected to the cecal ligation and puncture (CLP) model of polymicrobial sepsis. The CLP model for polymicrobial sepsis is the model which most closely resemble human sepsis. Advantages of the CLP model include the polymicrobial flora used for development of sepsis, nonrequirement for growing microbes, and the similar cytokine profile to human sepsis. CLP involves exposure and ligation of a portion of the cecum, followed by needle puncture and extrusion of fecal content into the body cavity. The severity of disease can be controlled by the size of needle puncture and length of cecal ligation. A rise in pro-inflammatory cytokines (including IL-6 and TNF-a) is observed after CLP. [00612] To evaluate the efficacy of compound 39 in treating the vascular leakage associated with sepsis, the CLP mouse model was conducted with male C57BL/6 mice treated with a single dose of vehicle (20% HPBCD/saline), JTE- 01330 mg/kg IP, or TDI-662160 mg/kg IP. The CLP surgery was conducted followed by compound administration. After an additional 4.5 hours, Evans Blue dye was injected, and brain samples were then analyzed 7.5 hours after administration of compounds. Animals in each treatment arm were excluded from this study if perfusion was incomplete. [00613] All studies were conducted in a blinded fashion. Vascular leakage in the brain was assessed using Evans Blue dye fluorescence compared with the wet weight of the brain. Treatment with compound 39 demonstrated significant
improvement in BBB leakage in the CLP mouse model of sepsis with a 33% decrease in RFU/g wet weight compared with the vehicle treatment (FIG.3). JTE- 013 showed a trend toward decreased leakage, although the effect was not statistically significant. A comparison of reduction in vascular leakage by compound 39 (33% decrease) with mice lacking S1PR2 (25% decrease) reveals that inhibition of leakage by compound 39 is demonstrating full or nearly full efficacy for inhibition of this pathway. Systemic plasma drug concentrations were measured at 4.5 hours. These measurements showed that 2.81 µM and 2.80 µM free drug concentrations (56.2 µM and 85.1 µM total drug concentrations) were attained for compound 39 and JTE-013, respectively. These PK results established that useful systemic plasma drug exposures were maintained during this study. In addition, when wild type (S1pr2+/+) and S1pr2-/- mice were subjected to polymicrobial sepsis (CLP; see Example 128), S1pr2-/- mice exhibited significantly decreased vascular leakage in the lungs (FIG.4, left panel) and improved survival (FIG.4 right panel). Therefore, genetic deletion of S1PR2 in mice results in dramatic reduction of vascular leakage (in lungs and brain) and mortality after sepsis. [00614] Together these data demonstrate that antagonism of S1PR2 is efficacious in the treatment of vascular leakage associated with sepsis. The S1PR2 antagonists were administered after the onset of sepsis, thus, they could be used to prevent or mitigate tissue injury and multiple organ dysfunction, ultimately decreasing mortality and chronic morbidity and disabilities in sepsis survivors. [00615] Since S1PR2 is expressed in the endothelium in human tissues and upregulated during inflammation, hypoxia and ischemia, the therapeutic potential of S1PR2 antagonists is very high. Example 128: In vivo studies [00616] C57BL6 mice (Jax laboratories) male, 24-28g, were used for the study. Wild type and S1pr2 -/- mice were used. All animal experiments used randomization to treatment groups and blinded assessment. tMCAO mouse model of stroke and treatments [00617] Transient focal cerebral ischemia was induced in mice by middle cerebral artery occlusion as we have previously described (tMCAO). Thirty-three mice (male, 24-28 g, C57BL6) were used in this study. Criteria for exclusion were development of subarachnoid hemorrhage, lack of reduction of cerebral blood flow or lack of recovery after reperfusion. Surgeries, as well as all behavioral and histological assessments were performed by an investigator blinded to the drug
treatment. Mice were anesthetized with 3% isoflurane vaporized in O2 for induction and 1.5% isoflurane for maintenance. Temperature was maintained at 36.5 ± 0.5ºC, controlled by a thermostatic blanket (CMA 450 Temp Controller for mice, Harvard Apparatus, Holliston, MA) throughout the procedure. The left common carotid artery was exposed and the occipital artery branches of the external carotid artery (ECA) were isolated and coagulated. The ECA was dissected distally and coagulated along with the terminal lingual and maxillary artery branches. The internal carotid artery (ICA) was isolated and the extracranial branch of the ICA was then dissected. A rubber silicon-coated monofilament suture (Filament size 6-0, diameter 0.09-0.11 mm, length 20mm; diameter with coating 0.23 +/- 0.02 mm; coating length 5 mm, Doccol Corp., Sharon, MA) was introduced into the ECA lumen through an incision and then gently advanced approximately 9 to 9.5 mm in the ICA lumen to block MCA blood flow. For reperfusion, the suture was withdrawn 60 min after MCAO. 2-D laser speckle flowmetry (PeriCam PSI HR, Perimed, Jarfalla, Sweeden) was used to confirm MCA occlusion and reperfusion. After removal of the suture, animals randomly received an intraperitoneal injection of vehicle or compounds. Determination of physiological parameters [00618] Physiological parameters (arterial O2 saturation, heart rate, pulse distention and respiratory rate) were recorded before, during and after tMCAO using the Mouse Ox Plus (Starr Life Sciences Corp., Oakmon, PA). After the surgery, all animals were maintained in a small animal heated recovery chamber (IMS Vetcare Chamber Recovery Unit, Harvard Apparatus, Holliston, MA). After recovery, animals were returned to their cages with free access to food and water. Neurobehavioral Testing [00619] Neurological function was evaluated at 24 h after reperfusion. Neurological deficit was graded on a score of 0 to 4 as previously described: 0, no observable deficit; 1, weakness in right forelimb; 2, forelimb flexion and circling when held by tail; 3, forelimb flexion, decreased resistance to lateral push, and spontaneous circling; and 4, forelimb flexion and being unable or difficult to ambulate. TTC staining and determination of infarct and edema ratios and infarct volumes [00620] Twenty-four hours after reperfusion, mice were anesthetized and decapitated. The brain was quickly removed from cranium, placed in -20 oC freezer for 20 min, and then cut into 1.5mm coronal slices using a rodent brain matrix. Sections were stained with 2% 2,3,5-triphenyltetrazolium chloride (TTC;
Sigma Co., St. Louis, MO) at 37°C for 10 min and scanned. Infarct area on each slice was determined by using Image analysis software (Image J, the National Institutes of Health, Bethesda, MD) to obtain the infarct ratios, edema ratios and infarct volumes per brain (in millimeters3). Infarct areas were calculated by using the following equation to correct for edema formation in the ischemic hemisphere: I=X-Y, where X is the area of the contralateral (non-ischemic) hemisphere and Y is the area of the intact regions of the ipsilateral (ischemic) hemisphere. Infarct ratios were obtained after normalization by the contralateral hemisphere. Edema ratios were calculated with the following formula: E=(Z-X)/X, where Z is the area of the ipsilateral hemisphere. Polymicrobial sepsis: cecal ligation and puncture model [00621] Under isoflurane anesthesia, a small incision was made in the peritoneal cavity (1.5 cm) to exteriorize the cecum, which was ligated at half the distance between the distal pole and the base of the cecum. Cecal puncture was conducted with a 18G needle and a small droplet of cecal content will be extruded from both holes to ensure patency. The cecum was relocated in the abdominal cavity and the incision sutured. Then, mice received pre-warmed normal saline (5mL/100g body weight) to avoid hypothermia. Determination of vascular leakage [00622] Two percent Evans blue dye solution is injected into animals 3 hours (brain leakage) or 40 minute (lung leakage) prior to endpoint . At endpoint 7.5 hours after drug administration, the mice were transcardially perfused with cold PBS/5 mM EDTA, and organs were harvested, weighed, and frozen. Organs were homogenized in 50% tricholoroacetic acid/PBS and incubated O/N at 4°C. Fluorescence intensity was measured at Ex 620/ Em 680. Vascular permeability was calculated as RFU/g wet weight. Statistical analyses, randomization and blinding [00623] All values reported are mean±s.e.m. P values were calculated with GraphPad Prism software, using one-way non-parametric ANOVA (Kruskal Wallis) followed by Dunn’s test or t test. The criterion for statistical significance was set at P<0.05. [00624]
