Description

Nrf2 modulators
Technical Field
The present invention relates to aryl analogs, pharmaceutical compositions containing them and their use as Nrf2 modulators.
Background
Nrf2(NF-E2 related factor 2) is a member of the cap and collar (CNC) family of transcription factors containing a characteristic basic-leucine zipper motif. Under basal conditions, Nrf2 levels were tightly controlled by the cytoplasmic actin binding repressor KEAP1 (Kelch-like ECH-associated protein 1), KEAP1 bound Nrf2 and targeted Nrf2 for ubiquitination and proteasome degradation via the Cul 3-based E3-ubiquitin ligase complex. Under conditions of oxidative stress, DJ1(PARK7) is activated and stabilizes Nrf2 protein by preventing Nrf2 from interacting with KEAP 1. Likewise, modification of the reactive cysteine on KEAP1 may result in a conformational change in KEAP1 that alters Nrf2 binding and promotes Nrf2 stabilization. Thus, the level of Nrf2 in the cytosol was low under normal conditions, but the system was designed to respond rapidly to environmental stress by increasing Nrf2 activity.
Inappropriately low Nrf2 activity in the face of sustained oxidative stress appears to be a potential pathological mechanism for Chronic Obstructive Pulmonary Disease (COPD). This may be the result of a change in the balance between an inappropriate absence of Nrf2 regulator from a positive regulator (e.g., DJ1) and an excess of negative regulators (e.g., Keap1 and Bach 1). Thus, restoration of Nrf2 activity in the lungs of COPD patients should restore the imbalance and mitigate deleterious processes such as apoptosis and inflammation of structural cells, including alveolar epithelial cells and endothelial cells. The result of these effects is an enhanced cytoprotective effect, maintenance of lung structure and structural repair in COPD lungs, slowing down disease progression. Thus, Nrf2 modulators can treat COPD (Boutten, a., et al 2011.Trends mol. med.17: 363-.
One example of inappropriately low Nrf2 activity is found in lung macrophages from COPD patients. These cells have impaired bacterial phagocytosis compared to similar cells from control patients, and this effect is reversed by the addition of Nrf2 activator in vitro. Thus, in addition to the effects mentioned above, restoration of appropriate Nrf2 activity may also save COPD exacerbations by reducing lung infections. This was demonstrated by the Nrf2 activator Sulforaphane (Sulforaphane), which increases the presence of COPD macrophages and alveolar macrophages from mice exposed to cigarette smokeCollagen structure Macrophage receptor of(MARCO), thereby increasing bacterial phagocytosis (Pseudomonas aeruginosa, atypical Haemophilus influenzae) and bacterial clearance in vitro and in vivo in these cells (Harvey, C.J., et al 2011.Sci. Transl. Med.3:78ra 32).
The therapeutic potential to target Nrf2 in the lung is not limited to COPD. More specifically, targeting the Nrf2 pathway can treat other human lung and respiratory diseases that present oxidative stress components, such as chronic and acute asthma, lung disease secondary to environmental exposure (including but not limited to ozone, diesel exhaust, and occupational exposure), fibrosis, acute lung infection (e.g., viral (Noah, t.l. et al 2014.PLoS ONE 9(6): e98671), bacterial or fungal), chronic lung infection, alpha 1 antitrypsin disease, and cystic fibrosis (CF, Chen, j. et al 2 008.PLoS One.2008;3(10):e3367)。
Therapies targeting the Nrf2 pathway also have a variety of potential uses outside the lung and respiratory system. Many diseases for which Nrf2 activators may be useful are autoimmune diseases (psoriasis, IBD, MS), suggesting that Nrf2 activators may be useful in autoimmune diseases in general.
Clinically, drugs targeting the Nrf2 pathway (bardoxolone methyl) have shown efficacy in diabetic patients with diabetic nephropathy/Chronic Kidney Disease (CKD) (Aleksunes, l.m., et al 2010.j. pharmacol. exp. ther.335:2-12), but phase III trials with this drug have been terminated in patients with the most severe stage of CKD. Furthermore, there is evidence to speculate that such treatment would be effective in sepsis-induced acute Kidney injury, other Acute Kidney Injury (AKI) (Shelton, l.m., et al 2013.Kidney International, Jun 19. doi: 10.1038/ki.2013.248), and renal disease or renal dysfunction observed during renal transplantation.
Bardoxolone methyl is currently being studied in patients with pulmonary hypertension in the cardiac region, and therefore drugs that target Nrf2 by other mechanisms may also be used in the disease. Also, it can be used in a variety of cardiovascular diseases, including but not limited to atherosclerosis, hypertension and heart failure (Oxidative Medicine and Cellular Longevity Volume 2013(2013), articule ID 104308, page 10).
Drugs that activate the Nrf2 pathway may also be useful in the treatment of severe neurodegenerative diseases including Parkinson's Disease (PD), Alzheimer's Disease (AD), Amyotrophic Lateral Sclerosis (ALS) (Brain res.2012mar 29; 1446:109-18.2011.12.064.Epub 2012Jan 12.) and Multiple Sclerosis (MS). Several in vivo models have demonstrated that Nrf2 KO mice are more susceptible to neurotoxic injury than their corresponding wild-type. Treatment of rats with the Nrf2 activator tert-butylhydroquinone (tBHQ) reduced cortical injury in rats in a cerebral ischemia-reperfusion model, and cortical glutathione levels increased following tBHQ administration in Nrf2 wild-type but not KO mice (Shih, a.y., et al 2005.j. neurosci.25: 10321-. TecfideraTM(dimethyl fumarate) (activation thereofOther targets, including Nrf2) have been approved in the united states for the treatment of relapsing-remitting Multiple Sclerosis (MS). Activation of Nrf2 also helps in the treatment of friedreich ataxia cases, where increased sensitivity to oxidative stress and impaired Nrf2 activation have been reported (Paupe v, et al, 2009, PLoS One; 4(1): e 4253).
There is preclinical evidence for specific protection of the Nrf2 pathway in models of inflammatory bowel disease (IBD, crohn's disease and ulcerative colitis) and/or colon Cancer (Khor, t.o., et al, 2008.Cancer prev.res. (philia) 1: 187-191).
Age-related macular degeneration (AMD) is a common cause of blindness in people over the age of 50. Smoking is a major risk factor for the development of non-neovascular (dry) AMD, and may also be a major risk factor for neovascular (wet) AMD. The findings in vitro and in preclinical species support the notion that the Nrf2 pathway is involved in the regulation of antioxidant responses in retinal epithelial cells and inflammation in preclinical models of ocular injury (Schimel, et al, 2011 am.j.pathol.178: 2032-. Fuchs Endothelial Dystrophy (FECD) is a progressive blinding disease characterized by apoptosis of Corneal Endothelial cells. This is an elderly disease and increased oxidative stress is associated with low levels of Nrf2 expression and/or function (Bitar, m.s., et al 2012 Invest ophthalmol. vis.sci., August 24,2012vol.53no. 95806-5813). In addition, Nrf2 activators may be useful in uveitis or other inflammatory eye diseases.
Nonalcoholic fatty liver disease (NASH) is a disease of fat deposition, inflammation and injury in the liver, which occurs in patients who drink little or no alcohol. In preclinical models, the development of NASH was greatly accelerated in KO mice lacking Nrf2 when challenged with methionine-and choline-deficient diets (chowdry s., et al 2010.Free rad.biol. & med.48: 357-) -371). Administration of the Nrf2 activators oltipraz and NK-252 significantly attenuated the progression of histological abnormalities, in particular liver fibrosis, in rats fed a choline-deficient L-amino acid-defined diet (Shimozono r. et al 2012, Molecular pharmacology.84: 62-70). Other liver diseases amenable to Nrf2 regulation are toxin-induced liver disease (e.g., acetaminophen-induced liver disease), viral hepatitis and liver cirrhosis (Oxidative Medicine and Cellular Longevity Volume 2013(2013), articule ID 763257, page 9).
Recent studies have also begun to elucidate the role of ROS in skin diseases such as psoriasis. Studies carried out in psoriasis patients show an increase in serum malondialdehyde and nitric oxide end-products and a decrease in erythrocyte-superoxide dismutase activity, catalase activity and total antioxidant status, which in each case correlate with a severity index of the disease (Dipali P.K., et al Indian J Clin biochem.2010 October; 25(4): 388-. Similarly, Nrf2 modulators may be useful in treating the local effects of dermatitis/radiation: (M. et al 2010 Genes&Devl.24: 1045-; 124(2):730-41).
Also data indicate that Nrf2 activators may be beneficial in preeclampsia, a disease that occurs in 2-5% of pregnant people and involves hypertension and proteinuria (Annals of anatomiy-Anatomischer Anzeiger Volume 196, Issue 5, 9 months 2014, p 268-277).
Preclinical data have shown that compounds with Nrf2 activating activity are better at reversing high altitude-induced lesions than compounds without Nrf2 activity, using animal and cell models of acute mountain sickness (Lisk c. et al, 2013, Free Radic Biol med. oct 2013; 63: 264-.

"alkyl" refers to a monovalent saturated hydrocarbon chain having the number of carbon member atoms specified. E.g. C1-4Alkyl refers to alkyl groups having 1 to 4 carbon member atoms. The alkyl group may be linear or branched. Representative branched alkyl groups have one, two, or three branches. Alkyl groups include methyl, ethyl, propyl (n-propyl and isopropyl) and butyl (n-butyl, isobutyl, sec-butyl and tert-butyl).
“C3-6Spirocycloalkyl "refers to spirocyclopropyl, spirobutyl, spirocyclopentane and spirohexane.
As used herein, the terms 'halogen' and 'halo' include fluoro, chloro, bromo and iodo, and fluoro, chloro, bromo and iodo, respectively.
When referring to a group, "substituted" means that one or more hydrogen atoms attached to a member atom in the group is replaced with a substituent selected from the defined group of substituents. It is to be understood that the term "substituted" includes the implicit proviso that the substitution complies with the valency allowed by the atom being substituted and the substituent, and that the substitution results in a stable compound (i.e., the compound does not spontaneously undergo transformation, e.g., by rearrangement, cyclization, or elimination, and the compound is sufficiently robust to be isolated from the reaction mixture). When it is stated that a group may contain one or more substituents, one or more (if desired) member atoms within the group may be substituted. Furthermore, a single member atom within the group may be substituted with more than one substituent, provided that such substitution complies with the permitted valency of the atom. Suitable substituents are as defined herein for each substituted or optionally substituted group.
The term "independently" means that when more than one substituent is selected from a plurality of possible substituents, those substituents may be the same or different. In other words, each substituent is individually selected from the entire set of possible substituents.
The invention also includes various isomers of the compounds of formula (I) and (II) and mixtures thereof. "isomers" refer to compounds having the same composition and molecular weight but different physical and/or chemical properties. The structural difference may be in the ability to construct (geometric isomers) or rotate the plane of polarized light (stereoisomers). The compounds of formula (I) or (II) contain one or more asymmetric centers (also known as chiral centers) and may therefore exist as individual enantiomers, diastereomers or other stereoisomeric forms, or as mixtures thereof. All such isomeric forms are included within the scope of the present invention, including mixtures thereof.
Chiral centers may also be present in substituents such as alkyl groups. When the stereochemistry of a chiral center present in formula (I) and (II) or in any of the chemical structures described herein is not specifically indicated, the structure is intended to encompass any stereoisomer and all mixtures thereof. Thus, the compounds of formulae (I) and (II) containing one or more chiral centers may be used as racemic mixtures, enantiomerically enriched mixtures or as the corresponding isomerically pure individual stereoisomers.
The individual stereoisomers of the compounds of formulae (I) and (II) containing one or more asymmetric centers may be resolved by methods known to those skilled in the art. For example, such a resolution can be performed by: (1) forming a diastereomeric salt, complex or other derivative; (2) selectively reacting with a stereoisomer-specific reagent, such as an enzymatic oxidation reaction or a reduction reaction; or (3) by gas-liquid or liquid chromatography in a chiral environment, e.g., on a chiral support such as a silica gel bound to a chiral ligand or in the presence of a chiral solvent. It will be appreciated by those skilled in the art that when the desired stereoisomer is converted to another chemical entity by one of the above separation procedures, a further step of liberating the desired form is required. Alternatively, specific stereoisomers may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents or by converting one enantiomer into the other by asymmetric transformation.
As used herein, "pharmaceutically acceptable" refers to those compounds, materials, compositions, and dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, or other problem or complication, commensurate with a reasonable benefit/risk ratio.
The skilled person will appreciate that pharmaceutically acceptable salts of the compounds of formulae (I) and (II) may be prepared. These pharmaceutically acceptable salts can be prepared in situ during the final isolation and purification of the compound or by separately treating the purified compound in its free acid or free base form with the appropriate base or acid, respectively.
In some embodiments, the compounds of formula (I) and (II) may contain acidic functional groups and are therefore capable of forming pharmaceutically acceptable base addition salts by treatment with an appropriate base. Examples of such bases include a) hydroxides, carbonates and bicarbonates of sodium, potassium, lithium, calcium, magnesium, aluminum and zinc; and b) primary, secondary and tertiary amines, including aliphatic, aromatic, aliphatic diamines and hydroxyalkylamines such as methylamine, ethylamine, 2-hydroxyethylamine, diethylamine, triethylamine, ethylenediamine, ethanolamine, diethanolamine and cyclohexylamine.
In some embodiments, the compounds of formula (I) and (II) may contain basic functional groups and are therefore capable of forming pharmaceutically acceptable acid addition salts by treatment with an appropriate acid. Suitable acids include pharmaceutically acceptable inorganic and organic acids. Representative pharmaceutically acceptable acids include hydrochloric, hydrobromic, nitric, sulfuric, sulfonic, phosphoric, acetic, glycolic, phenylacetic, propionic, butyric, valeric, maleic, acrylic, fumaric, succinic, malic, malonic, tartaric, citric, salicylic, benzoic, tannic, formic, stearic, lactic, ascorbic, methanesulfonic, p-toluenesulfonic, oleic, lauric and the like.
The term "compound of formula (I) or (II)" or "said compound of formula (I) or (II)" as used herein refers to one or more compounds of formula (I) or (II). The compounds of formulae (I) and (II) may be present in solid or liquid form. In the solid state, it may be present in crystalline or amorphous form or in the form of a mixture thereof. It is understood by those skilled in the art that pharmaceutically acceptable solvates may be formed from crystalline compounds, wherein solvent molecules are incorporated in the crystal lattice during crystallization. Solvates may include non-aqueous solvents such as, but not limited to, ethanol, isopropanol, DMSO, acetic acid, ethanolamine, or ethyl acetate, or they may include water as the solvent, which is incorporated in the crystal lattice. When water is the solvent incorporated in the crystal lattice, such solvates are commonly referred to as "hydrates". Hydrates include stoichiometric hydrates as well as compositions containing variable amounts of water. The present invention includes all such solvates.
The skilled person will also appreciate that some compounds of the invention, including various solvates thereof, that exist in crystalline form may exist in polymorphic form (i.e. the ability to occur in different crystalline structures). These different crystalline forms are often referred to as "polymorphs". The present invention includes all such polymorphs. Polymorphs have the same chemical composition, but differ in the packing, geometric arrangement and other descriptive properties of the crystalline solid state. Thus, polymorphs can have different physical properties such as shape, density, hardness, deformability, stability, and dissolution properties. Polymorphs typically have different melting points, IR spectra and X-ray powder diffraction patterns, which can be used for identification. The skilled person understands that different polymorphs can be produced, e.g. by changing or adjusting the reaction conditions or reagents used in the preparation of the compounds. For example, changes in temperature, pressure or solvent can result in polymorphs. In addition, one polymorph may spontaneously convert to another polymorph under certain conditions.
The present invention also includes isotopically-labeled compounds, which are identical to those recited in formulas (I) and (II) and their attendant formulas, except that one or more atoms are replaced by an atom having an atomic mass or mass number different from that normally found in nature. Examples of isotopes that can be incorporated into the compounds of the invention and pharmaceutically acceptable salts thereof include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, iodine and chlorine, for example2H、3H、11C、13C、14C、15N、17O、18O、31P、32P、35S、18F、36Cl、123I and125I。
compounds of the present invention and pharmaceutically acceptable salts of said compounds containing the aforementioned isotopes and/or other isotopes of other atoms are within the scope of the present invention. Isotopically-labelled compounds of the invention, e.g. in which a radioactive isotope is incorporated, e.g.3H,14Those compounds of C are used in drug and/or substrate tissue distribution assays. Tritiated i.e.3H and carbon-14 i.e14The C isotope is particularly preferred because of its ease of preparation and ease of detection.11C and18the F isotope is particularly useful in PET (positron emission tomography),125the I isotope is particularly useful in SPECT (single photon emission computed tomography), all of which are used in brain imaging. In addition, with heavier isotopes such as deuterium 2Some therapeutic advantages are obtained by H substitution due to higher metabolic stability such as half-life in vivoIncreased or reduced dosage requirements and are therefore preferred in some circumstances. Isotopically labeled compounds of formulae (I) and (II) of the present invention and ancillary compounds thereof can generally be prepared by carrying out the procedures described in the schemes and/or in the examples below, wherein a non-isotopically labeled reagent is replaced by a readily available isotopically labeled reagent.

BEAS-2B NQO1 MTT test
NAD (P) H: benzoquinone oxidoreductase 1(NQO1), also known as DT diaphorase, is a homodimeric FAD-containing enzyme that catalyzes the obligatory nad (p) H-dependent two-electron reduction of quinones and protects cells from the toxic and neoplastic effects of free radicals and reactive oxygen species generated by one-electron reduction. Transcription of NQO1 is finely regulated by Nrf2, so NQO1 activity is a good marker of Nrf2 activation. On the first day, frozen BEAS-2B cells (ATCC) were thawed in a water bath, counted and resuspended at a concentration of 250,000 cells/mL. 50 microliters of cells were seeded in 384-well black clear-bottom plates. The plates were incubated at 37 ℃ with 5% CO2The culture was carried out overnight. The next day, plates were centrifuged and 50nL of compound or control was added to the cells. The plates were then incubated at 37 ℃ with 5% CO2Culturing for 48 h. On day four, the medium was aspirated from the plate and a crude cell lysate was prepared by: 13 μ L of 1X Cell Signaling Technologies lysis buffer was added, wherein 1 complete, mini, EDTA-free protease inhibitor tablet (Roche) was added per 10mL of lysis buffer. After lysis, the plates were incubated at room temperature for 20 minutes. 2 microliters of lysate were removed for use in the Cell Titer Glo assay (Promega) and a MTT mixture (MTT cocktail) was prepared (Prochaska et al 1998) for measuring NQO1 activity. To each well 50 microliters of MTT mix was added, the plates were centrifuged and analyzed on an Envision plate reader (Perkin Elmer) for 30 minutes using absorbance 570nm tags. Product formation pEC which is dynamically measured and induced by NQO1 specific activity 50Was calculated by plotting the change in absorption (. DELTA.OD/min) against the logarithm of the compound concentration and then performing a 3-parameter fit.

Nrf2-Keap1 FP test
One model for Nrf2-Keap1 interaction is through two binding sites in the Neh2 domain on Nrf 2. These two sites are called the DLG binding motif (latch domain, affinity of μ M class) and the ETGE binding motif (hinge domain, affinity of nM class). The Keap1 protein consists of an N-terminal region (NTR), a broad complex (broad complex), a tramtramtrack and brick a' brac domain (BTB), an intervening region (IVR), a double glycine repeat domain (DGR or Kelch), and a C-terminal region. The DLG and ETGE motifs of the Neh2 domain of Nrf2 bound with different affinities to the Kelch domain of Keap 1. In the Keap1 Kelch Fluorescence Polarization (FP) assay, a TAMRA-labeled 16mer peptide (AFFAQLQLDEETGEFL) containing the ETGE motif of Nrf2 and the Kelch domain of Keap1(321-609) was used. This assay determines whether the compound interferes with the binding between Keap1(361-609) and the TAMRA-labeled peptide. Binding of the TAMRA-labeled Nrf2 peptide to Keap1 (321-. If the compound interferes with the binding between the peptide and the protein, this will result in a decrease in the assay signal. Thus, the assay signal is inversely proportional to the inhibition of binding.
FP test
100nL of 100X compound dose-response curve in DMSO (serial 3-fold dilutions) was usedThe Echo liquid handling system (Labcyte) was added to 384-well low volume black assay plates (Greiner, #784076) with DMSO in columns 6 and 18. The highest concentration of compound is in columns 1 and 13. Keap1(321-609) was assayed in 1 Xassay buffer (50mM Tris, pH 8.0, 100mM NaCl, 5mM MgCl)21mM DTT, 2mM CHAPS and 0.005% BSA) to 40nM (2X) and 5ul was added to all wells of the compound plate with a Multidrop Combi (Thermo Electron Corporation) equipped with a metal tip dispenser, except column 18. Column 18 received only 5ul of assay buffer. Subsequently, 5. mu.L of 16nM (2X) Tamra-labeled peptide (AFFAQLQLDEETGEFL, 21)stCentury Biochemicals) were added to all wells of the plate. The plate was spun at 500rpm for 1min, incubated at room temperature for 1 hour and read on an analysis GT (Molecular Devices) equipped with excitation (530/25nm) and emission (580/10nm) filters designed for Tamra probes. A 561nm dichroic mirror is also used in the analysis. The final assay concentrations of the Keap1(321-609) and Tamra-labeled peptides were 20nM and 8nM, respectively. Fluorescence measurements (expressed in mP) were used in the transformation of the data. Compound activity was calculated based on percent inhibition, normalized to the control in the assay (control 1 containing both Tamra peptide and Keap1(321-609) (0% response), control 2 containing only Tamra peptide (100% response)). The data analysis was processed using the software package Abase XE (Surrey, United Kingdom). The% inhibition value is calculated by the following equation:
100- (100 ((compound response-mean control 2)/(mean control 1-mean control 2))). To calculate pIC50Abase XE uses a four parameter equation.
All examples described herein were active in the Keap1/Nrf2 FP assay.
NRF2-Keap1TR-FRET test
In the Nrf2-Keap1TR-FRET (time-resolved fluorescence resonance energy transfer) assay, the full-length Nrf2 protein and the full-length Keap1 protein (Keap1 exists as a dimer) were used. This assay detects the ability of compounds to replace FlagHis-tagged Keap1 to bind to biotinylated, Avi-tagged Nrf2 protein. biotin-Nrf 2 was bound to streptavidin-europium (a component of the assay mixture) and Keap1-FlagHis was recognized by anti-Flag APC (allophycocyanin) antibodies (also a component of the assay mixture). If binding occurs between the two proteins, there will be an energy transfer from Eu +3 (donor) at 615nm to APC (acceptor) at 665 nm. Potential Keap1 inhibitors will cause a reduction in TR-FRET signals by interfering with Keap1 binding to Nrf 2.
100 nanoliters of 100X compound dose response curves (serial 3-fold dilutions) in DMSO in columns 6 and 18 were stamped into 384-well low-volume black assay plates (Greiner, #784076) using the Echo liquid handling system (labcell). The highest concentrations of compounds are located in columns 1 and 13. All reagents were in assay buffer (50mM Tris, pH 8.0,5mM MgCl) 2100mM NaCl, 0.005% BSA, 1mM DTT and 2mM CHAPS). BSA, DTT and CHAPS were added to assay buffer on the day of assay. Using a Multidrop comb (Thermo Electron Corporation) equipped with a metal head dispenser, 5ul of 25nM Keap1-FlagHis protein was added to all wells of the compound plate except the wells in column 18. The wells in column 18 instead receive 5ul of assay buffer. The plate was centrifuged at 500rpm for 1 minute, the plate cover was closed, and the plate was incubated at 37 ℃ for 2.25 hours. The plate was then removed from the incubator and allowed to cool to room temperature for 15 minutes. Then 5 microliters of 50nM biotin-Nrf 2 protein was added to all wells of the plate and the plate was centrifuged at 500rpm for 1 minute and then incubated at 4 ℃ for 1.25 hours. The plates were then allowed to warm to room temperature for 15 minutes, followed by the addition of 10ul of the assay mix (1nM streptavidin Eu + W1024 and 5. mu.g/ml mouse anti-DYKDDDDK IgG conjugated to SureLight APC antibody; both from Columbia Biosciences) to all wells. The plates were centrifuged at 500rpm for 1 minute, incubated at room temperature for 1 hour, and read on an Envision plate reader using a 320nm excitation filter and 615nm and 665nm emission filters. Compound responses (% inhibition) and potency (pIC50) were calculated based on the ratio of the two emissions (665nm/615nm), and the transformed data were then normalized to the controls in the assay (control 1 ═ 1% DMSO in the presence of Nrf2 and Keap1 proteins, control 2 ═ 1% DMSO in the absence of protein). Data analysis was processed using the software package Abase XE (Surrey, United Kingdom) . The% inhibition value was calculated from the ratio (converted) data by the following equation:
100- (100 × (compound response-mean control 2)/(mean control 1-mean control 2)).
For calculation of pIC50, Abase XE uses a 4 parameter equation.

In the Nrf2-Keap1 TR-FRET (time-resolved fluorescence resonance energy transfer) low protein assay, the full-length Nrf2 protein and the full-length Keap1 protein (Keap1 is present as a dimer) were used. This assay detects the ability of compounds to bind biotinylated Avi-Nrf2 protein instead of Keap1 FlagHis. biotin-Nrf 2 was bound to streptavidin-europium (a component of the assay mixture) and Keap1 FlagHis was recognized by anti-Flag APC (allophycocyanin) antibodies (also a component of the assay mixture). If binding occurs between the two proteins, there will be an energy transfer from Eu +3 (donor) at 615nm to APC (acceptor) at 665 nm. A potential Nrf2 inhibitor would cause a reduction in TR-FRET signal by interfering with the binding of Keap1 to Nrf 2.
A 10 nanoliter dose response curve of 100X compound (serial 3-fold dilutions) in DMSO in columns 6 and 18 was stamped into 384-well low-volume black assay plates (Greiner, #784076) using the Echo liquid handling system (labcell). An additional 90nl of DMSO was added per well to bring the total volume to 100nl per well. The highest concentration of compound was located in columns 1 and 13, with serial dilutions across rows. All reagents were in assay buffer (50mM Tris, pH 8.0,5mM MgCl) 2100mM NaCl, 0.005% BSA, 1mM DTT and 2mM CHAPS). BSA, DTT and CHAPS were added to assay buffer on the day of assay. Using a Multidrop Combi (Thermo Electron Corporation) equipped with a metal head dispenser, 5ul of 1.25nM Keap1 flag his protein was added to all wells of the compound plate except for the wells in column 18. The wells in column 18 instead receive 5ul of assay buffer. The plate was centrifuged at 500rpm for 1 minute, the plate cover was closed, and the plate was incubated at 37 ℃ for 2.25 hours. The plate was then removed from the incubator and allowed to cool to room temperature for 15 minutes. Then 5 microliters of 2.5nM biotin-Nrf 2 protein was added to the plateAnd the plate was centrifuged at 500rpm for 1 minute, and then incubated at 4 ℃ for 1.25 hours.

The dosage may be administered until the desired therapeutic effect is achieved or may be administered sporadically to maintain the desired therapeutic effect. Suitable dosing regimens for the compounds of the invention depend on the pharmacokinetic properties of the compound, such as absorption, distribution and half-life, which can be determined by the skilled person. In addition, a suitable dosing regimen for a compound of the invention (including the duration of administration of the regimen) will depend upon the condition being treated, the severity of the condition being treated, the age and physical condition of the patient being treated, the medical history of the patient being treated, the nature of concurrent therapy, the desired therapeutic effect, and similar factors within the knowledge and expertise of the skilled artisan. The skilled artisan also understands that a suitable dosing regimen may need to be adjusted in view of the individual patient's response to the dosing regimen, or over time as the individual patient's needs change.
The usual daily dosage may vary depending on the particular route of administration selected. Common dosage ranges for oral administration are from 1mg to 1,000mg per person per day. The preferred dosage is 1-500mg once daily, more preferably 1-100mg per person daily. The Intravenous (IV) dose ranges from 0.1 to 1,000 mg/day, preferably from 0.1 to 500 mg/day and more preferably from 0.1 to 100 mg/day. The daily dose for inhalation is in the range of 10. mu.g to 10 mg/day, preferably 10. mu.g to 2 mg/day and more preferably 50. mu.g to 500. mu.g/day.
In addition, the compounds of the present invention may be administered as prodrugs. As used herein, a "prodrug" of a compound of the present invention is a functional derivative of the compound that, upon administration to a patient, ultimately releases the compound of the present invention in vivo. Administration of a compound of the invention in prodrug form may enable the skilled person to (a) alter the time at which the compound begins to act in vivo; (b) altering the duration of action of the compound in vivo; (c) altering the transport or distribution of the compound in vivo; (d) altering the solubility of the compound in vivo; and (e) overcoming side reactions or other difficulties encountered with the compounds. Common functional derivatives used to prepare prodrugs include modifications of the compounds that are cleaved chemically or enzymatically in vivo. Such modifications are well known to those skilled in the art and include the preparation of phosphates, amides, ethers, esters, thioesters, carbonates and carbamates.
Composition comprising a metal oxide and a metal oxide
The compounds of the present invention will generally, but not necessarily, be formulated into pharmaceutical compositions prior to administration to a patient. Thus, in another aspect of the invention, it relates to a pharmaceutical composition comprising a compound of the invention and one or more pharmaceutically acceptable excipients.
The pharmaceutical compositions of the present invention may be prepared and packaged in bulk form, wherein a safe and effective amount of a compound of the present invention may be removed and then administered to the patient in the form of a powder or syrup. Alternatively, the pharmaceutical compositions of the present invention may be prepared and packaged in unit dosage form, wherein each physically discrete unit contains a safe and effective amount of a compound of the present invention. When prepared in unit dosage form, the pharmaceutical compositions of the invention will generally contain from 1mg to 1000 mg.
The pharmaceutical compositions of the invention will generally contain one compound of the invention. However, in some embodiments, the pharmaceutical compositions of the present invention contain more than one compound of the present invention. For example, in some embodiments, a pharmaceutical composition of the invention contains two compounds of the invention. In addition, the pharmaceutical compositions of the present invention may optionally further comprise one or more additional pharmaceutically active compounds.
As used herein, "pharmaceutically acceptable excipient" refers to a pharmaceutically acceptable substance, composition or vehicle involved in imparting form or consistency to the pharmaceutical composition. Each excipient must be compatible with the other ingredients of the pharmaceutical composition when mixed, thereby avoiding interactions that would substantially reduce the efficacy of the compounds of the invention when administered to a patient and that would result in a non-pharmaceutically acceptable pharmaceutical composition. Furthermore, each excipient must of course be of sufficiently high purity to be pharmaceutically acceptable.
The compounds of the present invention and pharmaceutically acceptable excipient(s) are generally formulated in a dosage form suitable for administration to the patient by the desired route of administration. For example, dosage forms include those suitable for: (1) oral administration, such as tablets, capsules, caplets, pills, lozenges, powders, syrups, elixirs, suspensions, solutions, emulsions, sachets (sachets) and cachets (2) parenteral administration, such as sterile solutions, suspensions and powders for reconstitution; (3) transdermal administration, such as transdermal patches; (4) rectal administration, e.g., suppositories; (5) inhalation, such as dry powders, aerosols, suspensions, and solutions; and (6) topical administration, such as creams, ointments, lotions, solutions, pastes, sprays, foams and gels.
Suitable pharmaceutically acceptable excipients will vary depending on the particular dosage form selected. In addition, suitable pharmaceutically acceptable excipients may be selected for the specific function they serve in the composition.

In one aspect, the present invention relates to solid oral dosage forms, such as tablets or capsules, comprising a safe and effective amount of a compound of the present invention and a diluent or filler. Suitable diluents and fillers include lactose, sucrose, dextrose, mannitol, sorbitol, starches (e.g., corn starch, potato starch, and pregelatinized starch), cellulose and its derivatives (e.g., microcrystalline cellulose), calcium sulfate, and dibasic calcium phosphate. The oral solid dosage form may further comprise a binder. Suitable binders include starches (e.g., corn starch, potato starch, and pregelatinized starch), gelatin, acacia, sodium alginate, alginic acid, tragacanth, guar gum, povidone, and cellulose and derivatives thereof (e.g., microcrystalline cellulose). The oral solid dosage form may further comprise a disintegrant. Suitable disintegrants include crospovidone, sodium starch glycolate, croscarmellose, alginic acid and sodium carboxymethylcellulose. The oral solid dosage form may further comprise a lubricant. Suitable lubricants include stearic acid, magnesium stearate, calcium stearate and talc.
In another aspect, the invention relates to a dosage form suitable for parenteral administration to a patient, including subcutaneous, intramuscular, intravenous, or intradermal administration. Pharmaceutical formulations suitable for parenteral administration include aqueous and non-aqueous sterile injection solutions which may contain anti-oxidizing agents, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may contain suspending agents and thickening agents. The formulations may be presented in unit-dose or multi-dose containers, for example sealed ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets.
In another aspect, the invention relates to a dosage form suitable for administration to a patient by inhalation. For example, the compounds of the invention may be inhaled into the lungs in the form of a dry powder, aerosol, suspension or solution.
Dry powder compositions for delivery to the lung by inhalation typically comprise a compound of the invention in the form of a finely divided powder and one or more pharmaceutically acceptable excipients in the form of a finely divided powder. Pharmaceutically acceptable excipients that are particularly suitable for use in dry powders are well known to those skilled in the art and include lactose, starch, mannitol, and mono-, di-and polysaccharides.
The dry powder compositions for use according to the invention may be administered by inhalation devices. As an example, such devices may include capsules and cartridges of, for example, gelatin, or blisters of, for example, laminated aluminum foil. In various embodiments, each capsule, cartridge, or blister may contain multiple doses of a composition according to the teachings herein. Examples of inhalation devices may include those intended for unit-dose or multi-dose delivery of compositions, including all devices described herein. As one example, in the case of multiple dose delivery, the formulation may be pre-metered (e.g., asSee GB2242134, U.S. patent nos. 6,032,666, 5,860,419, 5,873,360, 5,590,645, 6,378,519 and 6,536,427 or Diskhaler, see GB 2178965, 2129691 and 2169265, U.S. patent nos. 4,778,054, 4,811,731, 5,035,237) or metered use (e.g. Turbuhaler, see EP 69715, or the devices described in U.S. patent No. 6,321,747). An example of a unit dose device is Rotahaler (see GB 2064336). In one embodiment of the process of the present invention,the inhalation device comprises an elongate strip of base sheet having a plurality of recesses spaced along its length and a peelable cover sheet sealing the same to define a plurality of receptacles each having an inhalable formulation therein containing a compound, optionally with other excipients and additives as taught herein. The peelable sealing device is an engineered sealing device, and in one embodiment, the engineered sealing device is a hermetic seal. Preferably, the slats are sufficiently flexible to be wound into a roll. The cover sheet and the base sheet preferably have front end portions which are not sealed to each other, and at least one of said front end portions is designed to be connected to a winding device. It is also preferred that the engineered seal between the base and cover sheets extends to its full width. It may be preferred that the cover sheet is peeled from the base sheet in a longitudinal manner from the head end of the base sheet.
The dry powder composition may also be present in an inhalation device, which allows two different components of the composition to be contained separately. Thus, for example, the components may be administered simultaneously, but stored separately, e.g. in separate pharmaceutical compositions, e.g. as described in WO 03/061743a1, WO 2007/012871a1 and/or WO 2007/068896. In one embodiment, the inhalation device allowing for separate containment of the components is an inhaler device having two peelable blister strips, each strip containing a pre-metered dose in a blister pocket arranged along its length, e.g. a plurality of containers within each blister strip. The device has an internal indexing mechanism that peels open the pockets of each strip and positions the blisters so that each newly exposed pocket of each stripThe dose is adjacent to a manifold that communicates with the mouthpiece of the device. As the patient inhales at the mouthpiece, each dose is simultaneously withdrawn from its associated pocket, enters the manifold and is entrained via the mouthpiece into the patient's respiratory tract. Another device that allows separate containment of different components is the DuOHALER of InnovataTM. In addition, in addition to simultaneous delivery, various configurations of inhalation devices provide for sequential or separate delivery of pharmaceutical compositions from the device.
