ISOXAZOLINES AS INHIBITORS OF FATTY ACID AMIDE HYDROLASE

CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims priority to United States provisional patent application serial numbers 61/179,280, 61/179,283, and 61/179,285 filed May 18, 2009, the entirety of each of which is hereby incorporated herein by reference.

BACKGROUND

[0002] Fatty acid amide hydrolase (FAAH), also referred to as oleamide hydrolase and anandamide amidohydrolase, is an integral membrane protein responsible for the hydrolysis of several important endogenous neuromodulating fatty acid amides (FAAs), including anadamide, oleoylethanolamide and palmitoylethanolamide, and is intimately involved in their regulation.
Because these FAAs interact with cannabinoid and vanilliod receptors, they are often referred to as "endocannabinoids" or "endovanilliods". Initial interest in this area focused on developing FAAH inhibitors to augment the actions of FAAs and reduce pain. Further investigation found FAAH inhibitors, through interactions of the FAAs with unique extracellular and intracellular receptors, can be used to treat a variety of conditions that include, but are not limited to, inflammation, metabolic disorders (e.g., obesity-related conditions and wasting conditions such as cachexias and anorexia), disorders of the central nervous system (e.g., disorders associated with neurotoxicity and/or neurotrauma, stroke, multiple sclerosis, spinal cord injury, movement disorders such as basal ganglia disorders, amylotrophic lateral sclerosis, Alzheimer's disease, epilepsy, mental disorders such as anxiety, depression, learning disorders and Schizophrenia, sleep disorders such as insomnia, nausea and/or emesis, and drug addiction), cardiac disorders (e.g., hypertention, circulatory shock, myocardial reperfusion injury and atherosclerosis) and glaucoma (Pacher et at., "The Endocannabinoid System as an Emerging Target of Pharmacotherapy" Pharmacological Reviews (2006) 58:389-462; Pillarisetti et at., "Pain and Beyond: Fatty Acid Amides and Fatty Acid Amide Hydrolase Inhibitors in Cardiovascular and Metabolic Diseases" Drug Discovery Today (2009) 597:1-14).

[0006] The details of additional embodiments of the invention are set forth in the accompanying Detailed Description and Exemplification as described below.
Other features, objects, and advantages of the invention will be apparent from this description and from the claims.

DEFINITIONS

[0007] Definitions of specific functional groups ad chemical terms are described in more detail below. The chemical elements are identified in accordance with the Periodic Table of the Elements, CAS version, Handbook of Chemistry and Physics, 75 th Ed., inside cover, and specific functional groups are generally defined as described therein. Additionally, general principles of organic chemistry, as well as specific functional moieties and reactivity, are described in Organic Chemistry, Thomas Sorrell, University Science Books, Sausalito, 1999;
Smith and March March's Advanced Organic Chemistry, 5 th Edition, John Wiley & Sons, Inc., New York, 2001; Larock, Comprehensive Organic Transformations, VCH Publishers, Inc., New York, 1989; and Carruthers, Some Modern Methods of Organic Synthesis, 3rd Edition, Cambridge University Press, Cambridge, 1987.

[0008] Certain compounds of the present invention can comprise one or more asymmetric centers, and thus can exist in various isomeric forms, e.g., enantiomers and/or diastereomers.
The compounds provided herein can be in the form of an individual enantiomer, diastereomer or geometric isomer, or can be in the form of a mixture of stereoisomers, including racemic mixtures and mixtures enriched in one or more stereoisomer. In certain embodiments, the compounds of the invention are enantiopure compounds. In certain other embodiments, mixtures of stereoisomers are provided.

[0009] Furthermore, certain compounds, as described herein may have one or more double bonds that can exist as either the cis or trans, or the E or Z isomer, unless otherwise indicated.
The invention additionally encompasses the compounds as individual isomers substantially free of other isomers, and alternatively, as mixtures of various isomers, e.g., racemic mixtures of E/Z
isomers or mixtures enriched in one E/Z isomer.

[0010] The terms "enantiomerically enriched," "enantiomerically pure" and "non-racemic,"
as used interchangeably herein, refer to compositions in which the percent by weight of one enantiomer is greater than the amount of that one enantiomer in a control mixture of the racemic composition (e.g., greater than 1:1 by weight). For example, an enantiomerically enriched preparation of the (S)-enantiomer, means a preparation of the compound having greater than 50% by weight of the (S)-enantiomer relative to the (R)-enantiomer, more preferably at least 75% by weight, and even more preferably at least 80% by weight. In some embodiments, the enrichment can be much greater than 80% by weight, providing a "substantially enantiomerically enriched," "substantially enantiomerically pure" or a "substantially non-racemic" preparation, which refers to preparations of compositions which have at least 85% by weight of one enantiomer relative to other enantiomer, more preferably at least 90% by weight, and even more preferably at least 95% by weight. In preferred embodiments, the enantiomerically enriched composition has a higher potency with respect to therapeutic utility per unit mass than does the racemic mixture of that composition. Enantiomers can be isolated from mixtures by methods known to those skilled in the art, including chiral high pressure liquid chromatography (HPLC) and the formation and crystallization of chiral salts; or preferred enantiomers can be prepared by asymmetric syntheses. See, for example, Jacques, et al., Enantiomers, Racemates and Resolutions (Wiley Interscience, New York, 1981); Wilen, S.H., et al., Tetrahedron 33:2725 (1977); Eliel, E.L. Stereochemistry of Carbon Compounds (McGraw-Hill, NY, 1962); and Wilen, S.H. Tables of Resolving Agents and Optical Resolutions p. 268 (E.L.

[0040] As used herein, a "pharmaceutically acceptable form thereof' includes pharmaceutically acceptable salts, hydrates, solvates, prodrugs, tautomers, isomers, and/or polymorphs of a compound of the present invention, as defined below and herein.

[0041] As used herein, the term "pharmaceutically acceptable salt" refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio.
Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19.
Pharmaceutically acceptable salts of the compounds of this invention include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N+(C1_ 4alkyl)4 salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate and aryl sulfonate.

[0042] In certain embodiments, the pharmaceutically acceptable form thereof is an isomer.
As used herein, the term "isomer" includes any and all geometric isomers and stereoisomers.
For example, "isomers" include cis- and trans-isomers, E- and Z- isomers, R-and S-enantiomers, diastereomers, (D)-isomers, (L)-isomers, racemic mixtures thereof, and other mixtures thereof, as falling within the scope of the invention.

[0043] In certain embodiments, the pharmaceutically acceptable form thereof is a tautomer.
As used herein, the term "tautomer" includes two or more interconvertable compounds resulting from at least one formal migration of a hydrogen atom and at least one change in valency (e.g., a single bond to a double bond, a triple bond to a single bond, or vice versa).
The exact ratio of the tautomers depends on several factors, including temperature, solvent, and pH.
Tautomerizations (i.e., the reaction providing a tautomeric pair) may catalyzed by acid or base. Exemplary tautomerizations include keto-to-enol; amide-to-imide; lactam-to-lactim;
enamine-to-imine;
and enamine-to-(a different) enamine tautomerizations.

As used herein, the term "hydrate" refers to a compound non-covalently associated with one or more molecules of water. Likewise, "solvate" refers to a compound non-covalently associated with one or more molecules of an organic solvent.

[0045] In certain embodiments, the pharmaceutically acceptable form thereof is a prodrug.
As used herein, the term "prodrug" refers to a derivative of a parent compound that requires transformation within the body in order to release the parent compound. In certain cases, a prodrug has improved physical and/or delivery properties over the parent compound. Prodrugs are typically designed to enhance pharmaceutically and/or pharmacokinetically based properties associated with the parent compound. The advantage of a prodrug can lie in its physical properties, such as enhanced water solubility for parenteral administration at physiological pH
compared to the parent compound, or it enhances absorption from the digestive tract, or it may enhance drug stability for long-term storage.

[0046] In certain embodiments, the pharmaceutically acceptable form thereof is a polymorph. As used herein, "polymorph" refers to a compound having more than one crystal structure, e.g., resulting from differences in molecular packing and/or molecular conformation of the compound in the solid state.

[00391] Pharmaceutically acceptable excipients include any and all solvents, diluents or other liquid vehicles, dispersion or suspension aids, surface active agents, isotonic agents, thickening or emulsifying agents, preservatives, solid binders, lubricants and the like, as suited to the particular dosage form desired. General considerations in the formulation and/or manufacture of pharmaceutical compositions agents can be found, for example, in Remington's Pharmaceutical Sciences, Sixteenth Edition, E. W. Martin (Mack Publishing Co., Easton, Pa., 1980), and Remington: The Science and Practice of Pharmacy, 21st Edition (Lippincott Williams & Wilkins, 2005).

[00392] Pharmaceutical compositions described herein can be prepared by any method known in the art of pharmacology. In general, such preparatory methods include the steps of bringing the active ingredient into association with a carrier and/or one or more other accessory ingredients, and then, if necessary and/or desirable, shaping and/or packaging the product into a desired single- or multi-dose unit.

[00393] Pharmaceutical compositions can be prepared, packaged, and/or sold in bulk, as a single unit dose, and/or as a plurality of single unit doses. As used herein, a "unit dose" is discrete amount of the pharmaceutical composition comprising a predetermined amount of the active ingredient. The amount of the active ingredient is generally equal to the dosage of the active ingredient which would be administered to a subject and/or a convenient fraction of such a dosage such as, for example, one-half or one-third of such a dosage.

[00394] Relative amounts of the active ingredient, the pharmaceutically acceptable carrier, and/or any additional ingredients in a pharmaceutical composition of the invention will vary, depending upon the identity, size, and/or condition of the subject treated and further depending upon the route by which the composition is to be administered. By way of example, the composition may comprise between 0.1 % and 100% (w/w) active ingredient.

[00395] Pharmaceutically acceptable excipients used in the manufacture of provided pharmaceutical compositions include inert diluents, dispersing and/or granulating agents, surface active agents and/or emulsifiers, disintegrating agents, binding agents, preservatives, buffering agents, lubricating agents, and/or oils. Excipients such as cocoa butter and suppository waxes, coloring agents, coating agents, sweetening, flavoring, and perfuming agents may also be present in the composition.

[00396] Exemplary diluents include calcium carbonate, sodium carbonate, calcium phosphate, dicalcium phosphate, calcium sulfate, calcium hydrogen phosphate, sodium phosphate lactose, sucrose, cellulose, microcrystalline cellulose, kaolin, mannitol, sorbitol, inositol, sodium chloride, dry starch, cornstarch, powdered sugar, etc., and combinations thereof.

[00410] Liquid dosage forms for oral and parenteral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredients, the liquid dosage forms may comprise inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (e.g., cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. In certain embodiments for parenteral administration, the conjugates of the invention are mixed with solubilizing agents such as Cremophor, alcohols, oils, modified oils, glycols, polysorbates, cyclodextrins, polymers, and combinations thereof.

[00411] Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions can be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation can be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.

[00412] The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

[00413] In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.

[00414] Compositions for rectal or vaginal administration are typically suppositories which can be prepared by mixing the conjugates of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active ingredient.

[00415] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active ingredient is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may comprise buffering agents.

[00416] Solid compositions of a similar type can be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally comprise opacifying agents and can be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes. Solid compositions of a similar type can be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polethylene glycols and the like.

[00417] The active ingredients can be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art.
In such solid dosage forms the active ingredient can be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may comprise buffering agents. They may optionally comprise opacifying agents and can be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes.

[00418] Dosage forms for topical and/or transdermal administration of a compound of this invention may include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants and/or patches. Generally, the active ingredient is admixed under sterile conditions with a pharmaceutically acceptable carrier and/or any needed preservatives and/or buffers as can be required. Additionally, the present invention contemplates the use of transdermal patches, which often have the added advantage of providing controlled delivery of an active ingredient to the body. Such dosage forms can be prepared, for example, by dissolving and/or dispensing the active ingredient in the proper medium. Alternatively or additionally, the rate can be controlled by either providing a rate controlling membrane and/or by dispersing the active ingredient in a polymer matrix and/or gel.

prophylactically effective amount of a compound means an amount of therapeutic agent, alone or in combination with other agents, which provides a prophylactic benefit in the prevention of the disease, disorder or condition. The term "prophylactically effective amount"
can encompass an amount that improves overall prophylaxis or enhances the prophylactic efficacy of another prophylactic agent.

[00443] As used herein "inhibition", "inhibiting", "inhibit" and "inhibitor", and the like, refer to the ability of a compound to reduce, slow, halt or prevent activity of a particular biological process (e.g., FAAH activity) in a cell relative to vehicle.

[00444] "FAAH-mediated condition" as used herein, refers to a disease, disorder or condition which is treatable by inhibition of FAAH activity. "Disease", "disorder" or "condition" are terms used interchangeably herein. FAAH-mediated conditions include, but are not limited to, painful conditions, inflammatory conditions, immune disorders, disorders of the central nervous system, metabolic disorders, cardiac disorders and glaucoma.

[00445] In certain embodiments, the FAAH-mediated condition is a painful condition. As used herein, a "painful condition" includes, but is not limited to, neuropathic pain (e.g., peripheral neuropathic pain), central pain, deafferentiation pain, chronic pain (e.g., chronic nociceptive pain, and other forms of chronic pain such as post-operative pain, e.g., pain arising after hip, knee, or other replacement surgery), pre-operative pain, stimulus of nociceptive receptors (nociceptive pain), acute pain (e.g., phantom and transient acute pain), non-inflammatory pain, inflammatory pain, pain associated with cancer, wound pain, bum pain, post-operative pain, pain associated with medical procedures, pain resulting from pruritus, painful bladder syndrome, pain associated with premenstrual dysphoric disorder and/or premenstrual syndrome, pain associated with chronic fatigue syndrome, pain associated with pre-term labor, pain associated with withdrawl symptoms from drug addiction, joint pain, arthritic pain (e.g., pain associated with crystalline arthritis, osteoarthritis, psoriatic arthritis, gouty arthritis, reactive arthritis, rheumatoid arthritis or Reiter's arthritis), lumbosacral pain, musculo-skeletal pain, headache, migraine, muscle ache, lower back pain, neck pain, toothache, dental/maxillofacial pain, visceral pain and the like.

[00446] One or more of the painful conditions contemplated herein can comprise mixtures of various types of pain provided above and herein (e.g. nociceptive pain, inflammatory pain, neuropathic pain, etc.). In some embodiments, a particular pain can dominate.
In other embodiments, the painful condition comprises two or more types of pains without one dominating. A skilled clinician can determine the dosage to achieve a therapeutically effective amount for a particular subject based on the painful condition.

[00447] In certain embodiments, the painful condition is neuropathic pain. The term "neuropathic pain" refers to pain resulting from injury to a nerve.
Neuropathic pain is distinguished from nociceptive pain, which is the pain caused by acute tissue injury involving small cutaneous nerves or small nerves in muscle or connective tissue.
Neuropathic pain typically is long-lasting or chronic and often develops days or months following an initial acute tissue injury. Neuropathic pain can involve persistent, spontaneous pain as well as allodynia, which is a painful response to a stimulus that normally is not painful.
Neuropathic pain also can be characterized by hyperalgesia, in which there is an accentuated response to a painful stimulus that usually is trivial, such as a pin prick. Neuropathic pain conditions can develop following neuronal injury and the resulting pain may persist for months or years, even after the original injury has healed. Neuronal injury may occur in the peripheral nerves, dorsal roots, spinal cord or certain regions in the brain. Neuropathic pain conditions include, but are not limited to, diabetic neuropathy (e.g., peripheral diabetic neuropathy); sciatica; non-specific lower back pain; multiple sclerosis pain; carpal tunnel syndrome, fibromyalgia; HIV-related neuropathy;
neuralgia (e.g., post-herpetic neuralgia, trigeminal neuralgia); pain resulting from physical trauma (e.g., amputation; surgery, invasive medical procedures, toxins, bums, infection), pain resulting from cancer or chemotherapy (e.g., chemotherapy-induced pain such as chemotherapy-induced peripheral neuropathy), and pain resulting from an inflammatory condition (e.g., a chronic inflammatory condition). Neuropathic pain can result from a peripheral nerve disorder such as neuroma; nerve compression; nerve crush, nerve stretch or incomplete nerve transsection; mononeuropathy or polyneuropathy. Neuropathic pain can also result from a disorder such as dorsal root ganglion compression; inflammation of the spinal cord; contusion, tumor or hemisection of the spinal cord; tumors of the brainstem, thalamus or cortex; or trauma to the brainstem, thalamus or cortex.

[00448] The symptoms of neuropathic pain are heterogeneous and are often described as spontaneous shooting and lancinating pain, or ongoing, burning pain. In addition, there is pain associated with normally non-painful sensations such as "pins and needles"
(paraesthesias and dysesthesias), increased sensitivity to touch (hyperesthesia), painful sensation following innocuous stimulation (dynamic, static or thermal allodynia), increased sensitivity to noxious stimuli (thermal, cold, mechanical hyperalgesia), continuing pain sensation after removal of the stimulation (hyperpathia) or an absence of or deficit in selective sensory pathways (hypoalgesia).

[00449] In certain embodiments, the painful condition is non-inflammatory pain. The types of non-inflammatory pain include, without limitation, peripheral neuropathic pain (e.g., pain caused by a lesion or dysfunction in the peripheral nervous system), central pain (e.g., pain caused by a lesion or dysfunction of the central nervous system), deafferentation pain (e.g., pain due to loss of sensory input to the central nervous system), chronic nociceptive pain (e.g., certain types of cancer pain), noxious stimulus of nociceptive receptors (e.g., pain felt in response to tissue damage or impending tissue damage), phantom pain (e.g., pain felt in a part of the body that no longer exists, such as a limb that has been amputated), pain felt by psychiatric subjects (e.g., pain where no physical cause may exist), and wandering pain (e.g., wherein the pain repeatedly changes location in the body).

[00450] In certain embodiments, the painful condition is inflammatory pain. In certain embodiments, the painful condition (e.g., inflammatory pain) is associated with an inflammatory condition and/or an immune disorder.

[00451] In certain embodiments, the FAAH-mediated condition is an inflammatory condition.
The term "inflammatory condition" refers to those diseases, disorders or conditions that are characterized by signs of pain (dolor, from the generation of noxious substances and the stimulation of nerves), heat (calor, from vasodilatation), redness (rubor, from vasodilatation and increased blood flow), swelling (tumor, from excessive inflow or restricted outflow of fluid), and/or loss of function (functio laesa, which can be partial or complete, temporary or permanent.

V. Methods of Determining Biological Activity [0012] Methods of determining the activity of the compounds provided herein for various therapeutic uses are known in the art. These include, but are not limited to, high throughput screening to identify compounds that bind to and/or modulate the activity of isolated FAAH, as well as in vitro and in vivo models of therapies.
[0013] Assays useful for screening the compounds provided herein may detect the binding of the inhibitor to FAAH or the release of a reaction product (e.g., fatty acid amide or ethanolamine) produced by the hydrolysis of a substrate such as oleoylethanolamide or ananadamide. The substrate can be labeled to facilitate detection of the released reaction products. U.S. Pat. No. 5,559,410 discloses high throughput screening methods for proteins, and U.S. Pat. Nos. 5,576,220 and 5,541,061 disclose high throughput methods of screening for ligand/antibody binding.
[0014] Methods for screening FAAH inhibitors for an antinociceptive effect are known in the art. For example, compounds can tested in the mouse hot-plate test and the mouse formalin test, and the nociceptive reactions to thermal or chemical tissue damage measured (for example, see U.S. Pat. No. 6,326,156 for a description of methods of screening for antinociceptive activity;
see also Cravatt et at. Proc. Natl. Acad. Sci. U.S.A. (2001) 98:9371-9376).
[0015] Two pharmacologically validated animal models of anxiety are the elevated zero maze test, and the isolation-induced ultrasonic emission test. The zero maze consists of an elevated annular platform with two open and two closed quadrants and is based on the conflict between an animal's instinct to explore its environment and its fear of open spaces (see, for example, Bickerdike, M. J. et al., Eur. J. Pharmacol., (994) 271, 403-411;
Shepherd, J. K. et al., Psychopharmacology, (1994) 116, 56-64). Clinically used anxiolytic drugs, such as the benzodiazepines, increase the proportion of time spent in, and the number of entries made into, the open compartments.
[0016] A second test for an anti-anxiety compound is the ultrasonic vocalization emission model, which measures the number of stress-induced vocalizations emitted by rat pups removed from their nest (see, for example, Insel, T. R. et al., Pharmacol. Biochem.
Behav., 24, 1263-1267 (1986); Miczek, K. A. et al., Psychopharmacology, 121, 38-56 (1995); Winslow, J. T. et al., Biol. Psychiatry, 15, 745-757 (1991).
[0017] The effect of the compounds provided herein in the treatment of depression can be tested in the model of chronic mild stress induced anhedonia in rats. This model is based on the observation that chronic mild stress causes a gradual decrease in sensitivity to rewards, for example consumption of sucrose, and that this decrease is dose-dependently reversed by chronic treatment with antidepressants. See, e.g., Willner, Paul, Psychopharmacology, 1997, 134, 319-329.
[0018] Another test for antidepressant activity is the forced swimming test (Nature 266, 730-732, 1977). In this test, animals are administered an agent 30 or 60 minutes before being placed in container of water, and the time during which they remain immobile is recorded. A decrease in the immobility time of the mice is indicative of antidepressant activity.
[0019] A similar test for antidepressant activity is the mouse caudal suspension test (Psychopharmacology, 85, 367-370, 1985). In this test, animals are administered an agent 30 or 60 minutes before being suspended by the tail, and their immobility time is recorded. A decrease in the immobility time of the mice is indicative of antidepressant activity.
[0020] Animal models are available for assessing anticonvulsant activity of test compounds (see, e.g., U.S. Pat. Nos. 6,309,406 and 6,326,156).
[0021] Inhibition of FAAH has been reported to induce sleep in test animals (see, e.g., U.S.
Pat. No. 6,096,784). Methods for studying sleep inducing compounds are known in the art (see, e.g., U.S. Pat. Nos. 6,096,784 and 6,271,015). Compounds can be administered to a test animal (e.g., rat or mouse) or a human and the subsequent time (e.g., onset, duration) spent sleeping (e.g., eyes closed, motor quiescence) can be monitored. See also WO 98/24396.
[0022] Methods for screening FAAH inhibitors which induce catalepsy are also well known in the art (see, e.g., Quistand et al. in Toxicology and Applied Pharmacology 173: 48-55 (2001);
Cravatt et al. Proc. Natl. Acad. Sci. U.S.A. 98:9371-9376 (2001)).
[0023] Methods of assessing appetitive behavior are known in the art (see, e.g., U.S. Pat. No.
6,344,474). One method of assessing the effect on appetite behavior is to administer a FAAH
inhibitor to a rat and assess its effect on the intake of a sucrose solution (see, e.g., W. C. Lynch et al., Physiol. Behav., 1993, 54, 877-880).

[0024] Two pharmacologically validated animal models of neuropathic pain are the rat spinal nerve ligation model (Chung model) and a rat model of chemotherapy-induced neuropathic pain.
After establishing neuropathy in these models, as a measure of mechanical allodynia, paw withdrawal thresholds were measured by stimulation with von Frey filaments (see, for example, Kim SH and Chung JM, Pain (1992) 50, 355-63; Nozaki-Taguchi N, et al., Pain (2001) 93, 69-76). Clinically used neuropathic pain drugs, such as the Gabapentin (Neurontin), increase the paw withdrawal threshold from stimulation with von Frey filaments.
[0025] Two pharmacologically validated animal models of inflammatory and mechanical pain are a joint compression model in rats treated with adjuvant or agents that produce joint degeneration. Treatment with clinically used anti-inflammatory agents such as naproxen increases the threshold of behavioral response to joint compression (see, for example, Wilson AW, et al., Eur. J. Pain (2006) 10, 537-49; Ivanavicius SA, et al., Pain (2007) 128, 272-282).
[0026] A pharmacologically validated animal models of cancer pain is mouse model where implantation in the calcaneus bone of fibrosarcoma cells produces paw hyperalgesia. Treatment with clinically used analgesics agents such as morphine increases the threshold of behavioral response to mechanical algesia (see, for example, Khasabova, et al., J.
Neurscience (2008) 28, 11141-52).

Example 351 Inhibition of Human FAAH
[00396] Human FAAH Preparation: COS-7 cells were split the day before, 1:5 into 150 mm x 25 mm cell culture dishes (Coming Inc., Cat. No. 430599). Transient transfection took place at 30-40% confluency according to FuGENE 6 Transfection Reagent (Roche, Cat. No.

001).
[00397] Transfection Procedure: The FuGENE transfection 6 reagent (45uL) was added to 1410 gL of media (DMEM, serum free without pen/strep) in a 15 mL conical tube and incubated at room temp for 5 minutes, followed by the addition of FAAH plasmid DNA (15 g) (OriGene Cat. No. TC119221, Genbank Accession No. NM001441.1, 0.67 ug/uL) and a further incubation of 15 minutes at room temperature. The resulting solution was added into one dish of 30-40% confluent COS-7 cells in a drop-wise manner. The COS-7 cell dish was subsequently incubated for 48 hours. The cells are then harvested.
[00398] Harvest procedure: Media was aspirated from the dishes and the cells rinsed with lOmL PBS. The PBS was removed and 3 mL of PBS added to the dish. The dish was scraped to resuspend the cells, and the subsequent cell suspension collected into a 15 mL
conical tube. The cells were pelleted by centrifugation at 1200 rpm for 5 minutes in a bench top centrifuge. PBS
was removed and the cell pellet snap frozen in liquid nitrogen and stored at -80 C.
[00399] COS-7 cells - FAAH purification:

(1) Fractionation: Frozen cell pellets from transient transfections were thawed on ice and resuspended in 12.5mM Hepes pH 8.0, 100mM NaCl, 1mM EDTA (10 mL/0.2 g cell pellet). The pellets were dounce homogenized and then sonicated to produce cell extract.
The cell extract was subsequently centrifuged at 1000 g to remove cellular debris. The pellet was discarded and the supernatant centrifuged at 13,000 g for 20 minutes. The pellet contained membrane bound FAAH. The supernatant was discarded and the pellet resolubilized.
(2) Re-solubilization: The fraction of interest, (13,000g, membrane fraction) was re-suspended in 2.3 mL re-suspension buffer (20mM Hepes pH 7.8, 10%v/v Glycerol, mM EDTA, 1% Triton X-100) and the sample incubated on ice for 1 hour and then centrifuged to remove any particulate matter. The supernatant containing solubilized human FAAH was aliquoted and snap frozen in liquid nitrogen and stored at -80 C until use.
(3) Characterization: Protein Concentration determined by Bradford assay.
SDS gel and Western blot to confirm presence of FAAH
FAAH activity assay Km determination - 96-well assay Linear dependence - 96-well assay Standard compound Ki determination - 384-well assay [00400] Human FAAH assay; Experimental Protocol: A 0.1 mg/mL Human FAAH
solution was made up in FAAH reaction buffer, and 24 ul pipeted into a 384 well plate.
To this was added 1 gL of a 3 fold serially diluted inhibitor from a DMSO stock solution. The FAAH solution and inhibitor were incubated for 30 minutes at room temperature. The FAAH reaction was initiated by the addition of 25 gL of 40 gM AMC Arachidonoyl Amide in FAAH reaction buffer, yielding a final reaction human FAAH preparation concentration of 0.05 mg/ml and AMC-Arachidonoyl substrate concentration of 20 M, reaction volume 50 L. The reaction was allowed to proceed for 4 hours at room temperature. The reaction was stopped by the addition of 25 gL 12 gM a-ketoheterocycle (Cayman Chemicals, catalogue # 10435). The microtiter plate was read in the envision plate reader.

[00401] The raw fluorescence was plotted on the y axis and the inhibitor concentration on the x axis to give a dose response inhibition curve. The data was fitted to a single site competitive inhibition equation, fixing the Km for the human enzyme to 12 gM and 9 gM
respectively.
[00402] Other assays which can be used to determine the inhibition of FAAH by the compounds of the present invention include: (1) a fluorescence-based assay for fatty acid amide hydrolase compatible with high-throughput screening as described in Manjunath et at., Analytical Biochemistry (2005) 343:143-151; and (2) a high-throughput screening for the discovery of inhibitors of fatty acid amide hydrolase using a microsome-based fluorescent assay.

Example 352 Evidence for Covalent Complex Formation between Serine-241 of FAAH and Isoxazolines [00403] Treatment of rat FAAH protein with the active site-directed irreversible inhibitor methoxy arachidonyl fluorophosphonate results in a crystal structure wherein methoxy arachidonyl phosphonate is covalently bound to the side chain of Ser-241 (Bracey et at., Science (2002) 298:1793-1796).
[00404] Based on this data, it is hypothesized that the isoxazoline compounds of the present invention form covalent complexes with the nucleophilic side chain of Ser-241.
This hypothesis is consistent with the kinetic data, with the proposed binding involving nucleophilic attack of the isoxazoline electrophile by the active site Ser-241, resulting in the elimination of the leaving group from the cytosolic port, and the subsequent formation of a covalent enzyme-isoxazoline adduct. Recovery of activity would subsequently involve a deacylation reaction, which would occur inefficiently, if at all, for the covalent enzyme-isoxazoline adduct.
[00405] Recovery of activity experiments were performed via a jump dilution method which involved rapidly diluting the enzyme-inhibitor complex 5-fold below its apparent Ki, and measuring activity as a function of time. Little or no enzyme activity was regained over a period of two hours, indicating essentially irreversible inhibition, or a very slowly hydrolysable complex, supporting the above hypothesis.
