The present invention relates to novel compounds having enzyme inhibitory activity, and to their use in the treatment of ASK1-mediated conditions, including autoimmune disorders, inflammatory diseases, including chronic kidney disease, cardiovascular diseases and neurodegenerative diseases. The invention also relates to methods for their preparation, and to pharmaceutical compositions containing such compounds.
Mitogen-activated protein kinase (MAPK) signaling cascades couple diverse extracellular and intracellular queues to appropriate cellular stress responses, including cell growth, differentiation, inflammation, and apoptosis (Kumar, S., Boehm, J., and Lee., J. C. (2003) Nat. Rev. Drug Dis. 2:717-726; Pimienta, G., and Pascual, J. (2007) Cell Cycle, 6: 2826-2632). MAPKs exist in three groups, MAP3Ks, MAP2Ks, and MAPKs, which are sequentially activated. MAPK3s directly respond to environmental signals and phosphorylate MAP2Ks, which in turn phosphorylate specific MAPKs. MAPKs then mediated the appropriate cellular response by phosphorylating cellular substrates, including transcription factors that regulate gene expression.
Apoptosis signal-regulating kinase 1 (ASK1) is a member of the mitogen-activated protein kinase kinase kinase (“MAP3K”) family that activates the c-Jun N-terminal protein kinase (“JNK”) and p38 MAP kinase (Ichijo, H., Nishida, E., Irie, K., Ichijo, H. (2009) Cell Comm. Signal. 7:1-10; Takeda, K., Noguchi, T., Naguro, I., and Ichijo, H. (2007) Annu. Rev. Pharmacol. Toxicol. 48: 1-8.27; Nagai, H., Noguchi, T., Takeda, K., and Ichijo, I. (2007) J. Biochem. Mol. Biol. 40:1-6). ASK1 undergoes activation via autophosphorylation at Thr838 in response to these signals and in turn phosphorylates MAP2Ks, such as MKK3/6 and MKK4/7, which then phosphorylate and activate p38 and JNK MAPKs, respectively. ASK2 is a related MAP3K that shares 45% sequence homology with ASK1 (Wang, X. S., Diener, K., Tan, T-H., and Yao, Z. (1998) Biochem. Biophys. Res. Commun. 253, 33-37. Although ASK2 tissue distribution is restricted, in some cell types ASK1 and ASK2 have been reported to interact and function together in a protein complex (Takeda, K., Shimozono, R., Noguchi, T., Umeda, T., Morimoto, Y., Naguro, I., Tobiume, K., Saitoh, M., Matsuzawa, A., and Ichijo, H. (2007) J. Biol. Chem. 282: 7522-7531; Iriyama, T., et al. (2009) Embo J. 28: 843-853) In non stressed conditions, ASK1 is kept in an inactive state through binding to its repressor Thioredoxin (Trx) (Saitoh, M., Nishitoh, H., Fuji, M., Takeda, K., Tobiume, K., Sawada, Y., Kawabata, M., Miyazono, K., and Ichijo, H. (1998) Embo J. 17:2596-2606), and through association with AKT (Zhang, L., Chen, J. and Fu, H. (1999) Proc. Natl. Acad. Sci. U.S.A 96:8511-8515).
Phosphorylation of ASK1 protein can lead to apoptosis or other cellular responses depending on the cell type. ASK1 activation and signaling have been reported to play an important role in a broad range of diseases including neurodegenerative, cardiovascular, inflammatory, autoimmunity, and metabolic disorders. In addition, ASK1 has been implicated in mediating organ damage following ischemia and reperfusion of the heart, brain, and kidney (Watanabe et al. (2005) BBRC 333, 562-567; Zhang et al., (2003) Life Sci 74-37-43; Terada et al. (2007) BBRC 364: 1043-49). Emerging evidence suggests that ASK2, either alone or in a complex with ASK1, may play important roles in human diseases as well. Therefore, therapeutic agents that function as inhibitors of ASK1 and ASK2 signaling complexes have the potential to remedy or improve the lives of patients suffering from such conditions.
U.S. Publication No. 2007/0276050 describes methods for identifying ASK1 inhibitors useful for preventing and/or treating cardiovascular disease and methods for preventing and/or treating cardiovascular disease in an animal. The methods comprise administering to the animal an ASK1 inhibitor and, optionally, a hypertensive compound.
U.S. Publication No. 2007/0167386 reports a drug for at least one of prevention and treatment of cardiac failure containing a compound that inhibits a functional expression of ASK1 protein in a cardiomyocyte, and a method for screening the drug.

A compound of a given Formula (e.g. the “compound of Formula (I)”) is intended to encompass the compounds of the invention as disclosed, and the pharmaceutically acceptable salts, pharmaceutically acceptable esters, hydrates, polymorphs, and prodrugs of such compounds. Additionally, the compounds of the invention may possess one or more asymmetric centers, and can be produced as a racemic mixture or as individual enantiomers or diastereoisomers. The number of stereoisomers present in any given compound of a given Formula depends upon the number of asymmetric centers present (there are 2n stereoisomers possible where n is the number of asymmetric centers). The individual stereoisomers may be obtained by resolving a racemic or non-racemic mixture of an intermediate at some appropriate stage of the synthesis, or by resolution of the compound by conventional means. The individual stereoisomers (including individual enantiomers and diastereoisomers) as well as racemic and non-racemic mixtures of stereoisomers are encompassed within the scope of the present invention, all of which are intended to be depicted by the structures of this specification unless otherwise specifically indicated.
The invention also included compounds of Formula I in which from 1 to n hydrogens attached to a carbon atom is/are replaced by deuterium, in which n is the number of hydrogens in the molecule. Such compounds exhibit increased resistance to metabolism, and are thus useful for increasing the half life of any compound of Formula I when administered to a mammal. See, for example, Foster, “Deuterium Isotope Effects in Studies of Drug Metabolism”, Trends Pharmacol. Sci. 5(12):524-527 (1984). Such compounds are synthesized by means well known in the art, for example by employing starting materials in which one or more hydrogens have been replaced by deuterium.
“Isomers” are different compounds that have the same molecular formula.
“Stereoisomers” are isomers that differ only in the way the atoms are arranged in space.
“Enantiomers” are a pair of stereoisomers that are non-superimposable mirror images of each other. A 1:1 mixture of a pair of enantiomers is a “racemic” mixture. The term “(±)” is used to designate a racemic mixture where appropriate.
“Diastereoisomers” are stereoisomers that have at least two asymmetric atoms, but which are not mirror-images of each other.
The absolute stereochemistry is specified according to the Cahn Ingold Prelog R S system. When the compound is a pure enantiomer the stereochemistry at each chiral carbon may be specified by either R or S. Resolved compounds whose absolute configuration is unknown are designated (+) or (−) depending on the direction (dextro- or laevorotary) that they rotate the plane of polarized light at the wavelength of the sodium D line.
The term “therapeutically effective amount” refers to an amount that is sufficient to effect treatment, as defined below, when administered to a mammal in need of such treatment. The therapeutically effective amount will vary depending upon the subject and disease condition being treated, the weight and age of the subject, the severity of the disease condition, the manner of administration and the like, which can readily be determined by one of ordinary skill in the art.
The term “treatment” or “treating” means any treatment of a disease in a mammal, including:
In many cases, the compounds of this invention are capable of forming acid and/or base salts by virtue of the presence of amino and/or carboxyl groups or groups similar thereto.
The term “pharmaceutically acceptable salt” of a given compound refers to salts that retain the biological effectiveness and properties of the given compound, and which are not biologically or otherwise undesirable.

“Prodrug” is a compound that, upon in vivo administration, is metabolized by one or more steps or processes or otherwise converted to the biologically, pharmaceutically or therapeutically active form of the compound. To produce a prodrug, the pharmaceutically active compound is modified such that the active compound will be regenerated by metabolic processes. The prodrug may be designed to alter the metabolic stability or the transport characteristics of a drug, to mask side effects or toxicity, to improve the flavor of a drug or to alter other characteristics or properties of a drug. By virtue of knowledge of pharmacodynamic processes and drug metabolism in vivo, those of skill in this art, once a pharmaceutically active compound is known, can design prodrugs of the compound (see, e.g., Nogrady (1985) Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pages 388-392).
“Polymorph” refers to the different crystal forms of a compound, resulting from the possibility of at least two different arrangements of the molecules of the compound in the solid state. Polymorphs of a given compound will be different in crystal structure but identical in liquid or vapor states. Different polymorphic forms of a given substance may differ from each other with respect to one or more physical properties, such as solubility and dissociation, true density, crystal shape, compaction behavior, flow properties, and/or solid state stability.
Names of compounds of the present invention are provided using ChemBioDraw Ultra 11. Other compounds or radicals may be named with common names, or systematic or non-systematic names. The naming and numbering of the compounds of the invention is illustrated with a representative compound of Formula (I)
which is named:
Coronary patients being treated for an acute cardiovascular disease event by administration of ASK1 inhibitors often exhibit diseases or conditions that benefit from treatment with other therapeutic agents. These diseases or conditions can be of the cardiovascular nature or can be related to pulmonary disorders, metabolic disorders, gastrointestinal disorders and the like. Additionally, some coronary patients being treated for an acute cardiovascular disease event by administration of an ASK1 inhibitor exhibit conditions that can benefit from treatment with therapeutic agents that are antibiotics, analgesics, and/or antidepressants and anti-anxiety agents.
Cardiovascular related diseases or conditions that can benefit from a combination treatment of ASK1 inhibitors with other therapeutic agents include, without limitation, angina, including stable angina, unstable angina (UA), exercised-induced angina, variant angina, arrhythmias, intermittent claudication, myocardial infarction including non-STE myocardial infarction (NSTEMI), heart failure including congestive (or chronic) heart failure, acute heart failure, or recurrent ischemia.
Therapeutic agents suitable for treating cardiovascular related diseases or conditions include anti-anginals, heart failure agents, antithrombotic agents, antiarrhythmic agents, antihypertensive agents, and lipid lowering agents.
The co-administration of ASK1 inhibitors with therapeutic agents suitable for treating cardiovascular related conditions allows enhancement in the standard of care therapy the patient is currently receiving.
Anti-anginals include beta-blockers, calcium channel blockers, and nitrates. Beta blockers reduce the heart's need for oxygen by reducing its workload resulting in a decreased heart rate and less vigorous heart contraction. Examples of beta-blockers include acebutolol (Sectral), atenolol (Tenormin), betaxolol (Kerlone), bisoprolol/hydrochlorothiazide (Ziac), bisoprolol (Zebeta), carteolol (Cartrol), esmolol (Brevibloc), labetalol (Normodyne, Trandate), metoprolol (Lopressor, Toprol XL), nadolol (Corgard), propranolol (Inderal), sotalol (Betapace), and timolol (Blocadren).
Nitrates dilate the arteries and veins thereby increasing coronary blood flow and decreasing blood pressure. Examples of nitrates include nitroglycerin, nitrate patches, isosorbide dinitrate, and isosorbide-5-mononitrate.
Calcium channel blockers prevent the normal flow of calcium into the cells of the heart and blood vessels causing the blood vessels to relax thereby increasing the supply of blood and oxygen to the heart. Examples of calcium channel blockers include amlodipine (Norvasc, Lotrel), bepridil (Vascor), diltiazem (Cardizem, Tiazac), felodipine (Plendil), nifedipine (Adalat, Procardia), nimodipine (Nimotop), nisoldipine (Sular), verapamil (Calan, Isoptin, Verelan), and nicardipine.

Examples of diuretics include hydrochlorothiazide, metolazone (Zaroxolyn), furosemide (Lasix), bumetanide (Bumex), spironolactone (Aldactone), and eplerenone (Inspra).
Angiotensin converting enzyme (ACE) inhibitors reduce the workload on the heart by expanding the blood vessels and decreasing resistance to blood flow. Examples of ACE inhibitors include benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), and trandolapril (Mavik).
Vasodilators reduce pressure on the blood vessels by making them relax and expand. Examples of vasodilators include hydralazine, diazoxide, prazosin, clonidine, and methyldopa. ACE inhibitors, nitrates, potassium channel activators, and calcium channel blockers also act as vasodilators.
Cardiac glycosides are compounds that increase the force of the heart's contractions. These compounds strengthen the pumping capacity of the heart and improve irregular heartbeat activity. Examples of cardiac glycosides include digitalis, digoxin, and digitoxin.
Antithrombotics inhibit the clotting ability of the blood. There are three main types of antithrombotics—platelet inhibitors, anticoagulants, and thrombolytic agents.
Platelet inhibitors inhibit the clotting activity of platelets, thereby reducing clotting in the arteries. Examples of platelet inhibitors include acetylsalicylic acid (aspirin), ticlopidine, clopidogrel (plavix), dipyridamole, cilostazol, persantine sulfinpyrazone, dipyridaimole, indomethacin, and glycoprotein IIb/IIIa inhibitors, such as abciximab, tirofiban, and eptifibatide (Integrelin). Beta blockers and calcium channel blockers also have a platelet-inhibiting effect.
Anticoagulants prevent blood clots from growing larger and prevent the formation of new clots. Examples of anticoagulants include bivalirudin (Angiomax), warfarin (Coumadin), unfractionated heparin, low molecular weight heparin, danaparoid, lepirudin, and argatroban.
Thrombolytic agents act to break down an existing blood clot. Examples of thrombolytic agents include streptokinase, urokinase, and tenecteplase (TNK), and tissue plasminogen activator (t-PA).
Antiarrhythmic agents are used to treat disorders of the heart rate and rhythm. Examples of antiarrhythmic agents include amiodarone, quinidine, procainamide, lidocaine, and propafenone. Cardiac glycosides and beta blockers are also used as antiarrhythmic agents.

Compounds provided in accordance with the present invention are usually administered in the form of pharmaceutical compositions. This invention therefore provides pharmaceutical compositions that contain, as the active ingredient, one or more of the compounds described, or a pharmaceutically acceptable salt or ester thereof, and one or more pharmaceutically acceptable excipients, carriers, including inert solid diluents and fillers, diluents, including sterile aqueous solution and various organic solvents, permeation enhancers, solubilizers and adjuvants. The pharmaceutical compositions may be administered alone or in combination with other therapeutic agents. Such compositions are prepared in a manner well known in the pharmaceutical art (see, e.g., Remington's Pharmaceutical Sciences, Mace Publishing Co., Philadelphia, Pa. 17th Ed. (1985); and Modern Pharmaceutics, Marcel Dekker, Inc. 3rd Ed. (G. S. Banker & C. T. Rhodes, Eds.)
The pharmaceutical compositions may be administered in either single or multiple doses by any of the accepted modes of administration of agents having similar utilities, for example as described in those patents and patent applications incorporated by reference, including rectal, buccal, intranasal and transdermal routes, by intra-arterial injection, intravenously, intraperitoneally, parenterally, intramuscularly, subcutaneously, orally, topically, as an inhalant, or via an impregnated or coated device such as a stent, for example, or an artery-inserted cylindrical polymer.
One mode for administration is parenteral, particularly by injection. The forms in which the novel compositions of the present invention may be incorporated for administration by injection include aqueous or oil suspensions, or emulsions, with sesame oil, corn oil, cottonseed oil, or peanut oil, as well as elixirs, mannitol, dextrose, or a sterile aqueous solution, and similar pharmaceutical vehicles. Aqueous solutions in saline are also conventionally used for injection, but less preferred in the context of the present invention. Ethanol, glycerol, propylene glycol, liquid polyethylene glycol, and the like (and suitable mixtures thereof), cyclodextrin derivatives, and vegetable oils may also be employed. 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. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like.
Sterile injectable solutions are prepared by incorporating a compound according to the present invention in the required amount in the appropriate solvent with various other ingredients as enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum-drying and freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.
Oral administration is another route for administration of compounds in accordance with the invention. Administration may be via capsule or enteric coated tablets, or the like. In making the pharmaceutical compositions that include at least one compound described herein, the active ingredient is usually diluted by an excipient and/or enclosed within such a carrier that can be in the form of a capsule, sachet, paper or other container. When the excipient serves as a diluent, it can be in the form of a solid, semi-solid, or liquid material (as above), which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, sterile injectable solutions, and sterile packaged powders.
Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup, and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl and propylhydroxy-benzoates; sweetening agents; and flavoring agents.
The compositions of the invention can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art. Controlled release drug delivery systems for oral administration include osmotic pump systems and dissolutional systems containing polymer-coated reservoirs or drug-polymer matrix formulations. Examples of controlled release systems are given in U.S. Pat. Nos. 3,845,770; 4,326,525; 4,902,514; and 5,616,345. Another formulation for use in the methods of the present invention employs transdermal delivery devices (“patches”). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds of the present invention in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g., U.S. Pat. Nos. 5,023,252, 4,992,445 and 5,001,139. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.
The compositions are preferably formulated in a unit dosage form. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient (e.g., a tablet, capsule, ampoule). The compounds are generally administered in a pharmaceutically effective amount. Preferably, for oral administration, each dosage unit contains from 1 mg to 2 g of a compound described herein, and for parenteral administration, preferably from 0.1 to 700 mg of a compound a compound described herein. It will be understood, however, that the amount of the compound actually administered usually will be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered and its relative activity, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.
For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.
The tablets or pills of the present invention may be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action, or to protect from the acid conditions of the stomach. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer that serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.
Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. Preferably, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions in preferably pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a facemask tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions may be administered, preferably orally or nasally, from devices that deliver the formulation in an appropriate manner.

It will be apparent given the description herein that the general schemes may be altered by substitution of the starting materials with other materials having similar structures to result in products that are correspondingly different. Descriptions of syntheses follow to provide numerous examples of how the starting materials may vary to provide corresponding products. Given a desired product for which the substituent groups are defined, the necessary starting materials generally may be determined by inspection. Starting materials are typically obtained from commercial sources or synthesized using published methods. For synthesizing compounds which are embodiments of the present invention, inspection of the structure of the compound to be synthesized will provide the identity of each substituent group. The identity of the final product will generally render apparent the identity of the necessary starting materials by a simple process of inspection, given the examples herein

When the reaction is substantially complete, the product of Formula (I) is isolated by conventional means, for example by filtration.
The compound of formula (2) is either commercially available or is prepared by means well know in the art. One example of the preparation of a compound of formula (2) in which X1 is nitrogen is shown in Reaction Scheme IA.
In general, a protected amino ester of formula (a) is reacted with hydrazine hydrate in a protic solvent, for example ethanol. The reaction is carried out at a temperature of about 50-90° C., for about 1-5 hours. When the reaction is substantially complete, the product of formula (b) is isolated by conventional means.

A carboxylic acid of formula (4) in which Z is a halogen, for example chloro, bromo, or iodo, is reacted with an amine of formula (2) in the same manner as described in Reaction Scheme I. The compound of formula (5) thus prepared is then reacted with a boronic acid derivative of R3, for example 3-pyridine boronic acid, in the presence of a phosphine ligand of a palladium halide derivative, for example dppf(Pd)Cl2 (diphenylphosphineferrocenepalladium chloride) and a mild base, for example potassium carbonate. The reaction is typically conducted in a mixture of inert solvents, for example a mixture of toluene, water, and ethanol, for about 60-100° C. for about 1-4 hours. When the reaction is substantially complete, the product of Formula (I) is isolated by conventional means, for example by reverse-phase HPLC.
A compound of Formula (I) in which R3 is a non-aromatic ring can be prepared by displacement of Z with a nucleophile, for example an amine, particularly a cyclic amine, or with an alcohol or thiol derivative. Typically, if the nucleophile is an amine, the reaction is carried out using the amine as a solvent if possible, or the reaction is carried out in a polar aprotic solvent, such as N,N-dimethylformamide, dimethylsulfoxide, or N-methylpyrrolidine, for example. The reaction mixture is maintained at about 80-119° C. for about 1-10 hours. When the reaction is substantially complete, the product of Formula (I) is isolated by conventional means, for example by reverse-phase HPLC.

The compound of formula (3) is placed in a sealable flask with an amine of formula R1NH2 together with a formamide of formula R1NHCHO in an inert solvent, for example toluene, in the presence of an acid, for example trifluoroacetic acid. The sealed flask is heated at about 100° C. for about 12-48 hours. When the reaction is substantially complete, the product is isolated by conventional means, for example by flash chromatography.
To a suspension of a compound of formula (4) in an inert solvent, for example toluene, is added N,N-dimethylformamide/N,N-dimethylacetamide complex. To this mixture is added a compound of formula R1NH2 and a carboxylic acid, for example acetic acid. The mixture is heated at about 100-160° C. in a microwave reactor for about 10-60 minutes. When the reaction is substantially complete, the product of Formula (I) is isolated by conventional means, for example by filtration of the precipitated solid.
Reaction Scheme IIIB shows the preparation of a compound of Formula (I) in which X1 is carbon.
To a solution of an imine of formula (5) in an inert solvent, or a mixture of inert solvents, for example a mixture of dimethoxyethane and methanol, is added toluenesulfonylmethyl isocyanide and an amine of formula R1NH2. The mixture is maintained at about 40-60° C. for about 6-24 hours, optionally adding a further amount of the isocyanide. When the reaction is substantially complete, the product of formula (6) is isolated by conventional means, for example by chromatography.
The compound of formula (6) is then converted to a compound of Formula (I) in which X1 is carbon in the same manner as described in Reaction Scheme II.
The following synthetic schemes represent a summary of specific reaction conditions used in the preparation of intermediates and compounds of Formula (I) of the present invention.
The amino moiety of the compound of formula (1) as an alkyl ester, for example a methyl ester, is first protected, for example as a benzyloxycarbonyl derivative. In general, the aminoester is dissolved in an inert solvent, for example a mixture of acetone and water, at about 0° C., and an amino protecting agent added, for example benzyloxycarbonyl chloride. The reaction mixture is allowed to warm to about room temperature for about 12-30 hours.

The ability of compounds to inhibit ASK1 kinase activity was determined using a time resolved fluorescence resonance energy transfer [TR-FRET] assay utilizing biotinylated myelin basic protein [biotin-MBP] as the protein substrate. A Beckman Biomek FX liquid handling robot was utilized to spot 2 μL/well of compounds in 2.44% aqueous DMSO into low volume 384-well polypropylene plates [Nunc, #267460] to give a final concentration of between 100 μM and 0.5 nM compound in the kinase assay. A Deerac Fluidics Equator was used to dispense 3 μL/well of 0.667 ng/μL [Upstate Biotechnologies, #14-606, or the equivalent protein prepared in-house] and 0.1665 ng/mL biotin-MBP [Upstate Biotechnologies, #13-111] in buffer (85 mM MOPS, pH 7.0, 8.5 mM Mg-acetate, 5% glycerol, 0.085% NP-40, 1.7 mM DTT and 1.7 mg/mL BSA) into the plates containing the spotted compounds. The enzyme was allowed to pre-incubate with compound for 20 minutes prior to initiating the kinase reaction with the addition of 5 μL/well 300 μM ATP in buffer (50 mM MOPS, pH 7.0, 5 mM Mg-acetate, 1 mM DTT, 5% DMSO) using the Deerac Fluidics Equator. The kinase reactions were allowed to proceed for 20 minutes at ambient temperature and were subsequently stopped with the addition of 5 μL/well 25 mM EDTA using the Deerac Fluidics Equator. The Biomek FX was then used to transfer 1 μL/well of each completed kinase reaction to the wells of an OptiPlate-1536 white polystyrene plate [PerkinElmer, #6004299] that contained 5 μL/well detection reagents (1.11 nM Eu-W1024 labeled anti-phosphothreonine antibody [PerkinElmer, #AD0094] and 55.56 nM streptavidin allophycocyanin [PerkinElmer, #CR130-100] in 1×LANCE detection buffer [PerkinElmer, #CR97-100]). The TR-FRET signal was then read on a Perkin Elmer Envision plate reader after incubating the plates at ambient temperature for 2 hours. The 100% inhibition positive control wells were generated by switching the order of addition of the EDTA and ATP solutions described above. These wells and 0% inhibition wells containing spots of 2.44% DMSO at the beginning of the assay were used in calculating the % inhibition for the test compounds.
When tested by the above method, the compounds of Formula (I) inhibited ASK1. For example;
