Description
[0001] KINASE MODULATORS AND METHODS OF USE THEREOF Field of the Invention The invention provides compounds that modulate the activity of kinases, such as Tyrosine Kinase 2 (TYK2). Background A variety of medical conditions that affect millions of people are caused or exacerbated by unregulated activity of protein kinases. For example, aberrant kinase activity is associated with autoimmune diseases, inflammatory diseases, bone diseases, metabolic diseases, neurological and neurodegenerative diseases, cancer, cardiovascular diseases, allergies, asthma, Alzheimer's disease, Parkinson's disease, skin disorders, eye diseases, infectious diseases and hormone-related diseases. For many such disorders, however, no effective inhibitor or activator exists for the particular kinase that causes the disorder or its symptoms. Consequently, patients continue to suffer from an array of disorders due to the lack of suitable medicaments for their conditions. Summary The invention provides compounds that modulate the activity of protein kinases that are associated with human diseases, disorders, and conditions. In particular, compounds of the invention inhibit TYK2, a member of the Janus Kinase (JAK) family of non-receptor protein kinases. Altered or unregulated activity of TYK2 promotes inflammation and is implicated in autoimmune diseases, such as psoriasis, lupus, multiple sclerosis, and inflammatory bowel disease. Thus, embodiments of the invention are useful as pharmaceutical compositions for treatment of such autoimmune conditions.

Janus tyrosine kinase (JAK) family members are regulators of multiple signal transduction pathways initiated by membrane Type I and Type II cytokine receptors. There are 4 JAK family members including JAK1, JAK2, JAK3, and TYK2 (Schwartz et al, 2017). One such association is with signal transducer and activator of transcription (STAT) signal transduction mediated cytokine responses. The JAK-STAT signaling pathway is a chain of interactions between proteins in a cell, and is involved in processes such as immunity, cell division, cell death, and tumor formation (Aaronson et al Science 2002). The binding of Type I and Type II cytokine receptor ligands, such as interferons and interleukins, to cell-surface receptors, causes the receptors to dimerize, which brings the receptor-associated JAKs into close proximity (Jalini et al, Genes and Cancer 2011), and sets off a sequence of downstream changes. There is a large body of evidence establishing the contribution of JAK-dependent cytokines to immunopathology, and clinical benefit can be provided by blocking these cytokines with biologics and small-molecule inhibitors. Some examples of this are the blockade of IL-6 in rheumatoid arthritis or IL-12 / IL-23 in inflammatory bowel disease (IBD) (Schwartz et al 2017). The tyrosine kinase 2 (TYK2) member of the JAK family specifically plays a role in the downstream signaling of Interleukin (IL)-12, IL-23, and type I interferons (Baker and Isaacs, Ann Rheum Dis., 2018; Burke et al, Sci Trans Med, 2019). Like other JAK family members, TYK2 heterodimerizes with other JAK family members to provide ligand specificity and regulate downstream signal transduction pathways (Fig 1). Many of these pathways are altered in diseases and drive chronic inflammation in IBD, Psoriasis, and systemic lupus erythematosus (SLE) (Schwartz et al, Nat Rev Drug Dis, 2017). In addition to the role of TYK2 signaling cascades in disease there has been a strong body of genetic evidence of pointing to a role for TYK2. Genetic association studies have linked the TYK2 locus to an impact of the susceptibility in SLE, psoriasis, and multiple sclerosis (MS). This identification has been replicated and expanded in a number of recent analyses, and TYK2 is now recognized as a susceptibility gene in a variety of inflammatory and autoimmune diseases, including type I diabetes (T1D). The common characteristic of these diseases are changes in immunological function and activation, and downstream damage to target organs (Li et al, PLOS One, 2020). The use of small-molecule inhibitors of TYK2 have allowed for the confirmation of several of these hypotheses. Previous work in human derived PBMCs have demonstrated the ability of TYK2 inhibition to reduce IL-12 / IL-23 signaling in rodents and humans TYK2 inhibition has also proven efficacious in preclinical models of disease for psoriasis and ulcerative colitis (Burke et al, Sci Trans Med, 2020). The preclinical effects in rodents have since translated to humans with deucravacitinib demonstrating efficacy in Psoriasis patirnts (Armstrong et al, Ann of Rheu Dis, 2020). The genetic contribution of TYK2 has also been confirmed preclinically with the use of TYK2 knockout (KO) or transgenic (TG)animals. For example, Type I interferon signaling is reduced in in TYK2 KO animals as compared to WT mice (Karaghiosoff, Immunity, 2000) and TG animals with the P1104 protective variant of TYK2 are almost completely protected in the experimental autoimmune encephalitis (EAE) mouse model of MS (Gorman et al, Frnt in Immunology, 2019). Together, this large body of evidence provides supportive data for the role of cytokine signaling, and the support for the development of safe TYK2 inhibitors for a variety of inflammatory disorders. The invention provides compounds that modulate the activity of protein kinases that are associated with human diseases, disorders, and conditions. In particular, compounds of the invention inhibit TYK2, a member of the Janus Kinase (JAK) family of non-receptor protein kinases. Altered or unregulated activity of TYK2 promotes inflammation and is implicated in autoimmune diseases, such as psoriasis, lupus, multiple sclerosis, and inflammatory bowel disease. Thus, embodiments of the invention are useful as pharmaceutical compositions for treatment of such autoimmune conditions. The invention also provides methods of using the compounds to modulate kinase activity in cells and to treat conditions, such as autoimmune conditions, for which modulation of kinase activity provides a therapeutic benefit.

In certain embodiments, the invention provides a pharmaceutical composition comprising a compound of Formula (I) – (V), or a pharmaceutically acceptable salt, stereoisomer, or solvate thereof, and a pharmaceutically acceptable carrier or diluent. In certain embodiments, the invention provides a method of inhibiting TYK2 activity in a subject in need thereof with a compound of Formula (I) – (V), or a pharmaceutically acceptable salt, stereoisomer, or solvate thereof or a pharmaceutical composition. In certain embodiments, the invention provides a method of treating a TYK2-mediated disease or disorder comprising administering to a subject in need thereof a compound of Formula (I) – (V), or a pharmaceutically acceptable salt, stereoisomer, or solvate thereof or a pharmaceutical composition. In certain embodiments, the TYK2-mediated disease or disorder is an autoimmune disorder, an inflammatory disorder, a proliferative disorder, an endocrine disorder, a neurological disorder, or a disorder associated with transplantation. Pharmaceutical compositions The present invention provides pharmaceutical compositions containing one or more compounds described above, or a pharmaceutically acceptable ester, prodrug, hydrate, solvate or salt of such a compound, optionally in combination with a pharmaceutically acceptable carrier. The invention further provides such compounds for the preparation of a medicament for the treatment of one or more diseases mentioned herein. A pharmaceutical composition may contain one or more compounds of the invention in a therapeutically effective amount. A therapeutically effective amount of a compound in accordance with this invention means an amount of compound that is effective to prevent, alleviate or ameliorate symptoms of disease or prolong the survival of the subject being treated. Determination of a therapeutically effective amount is within the skill in the art. The therapeutically effective amount or dosage of a compound according to this invention can vary within wide limits and may be determined in a manner known in the art. Such dosage may be adjusted to the individual requirements in each particular case including the specific compound being administered, the route of administration, the condition being treated, as well as the patient being treated. Compositions of the invention may include a vehicle for delivery of one or more compounds of the invention. For example, the composition may contain particles, such as nanoparticles, microparticles, liposomes, micelles, and virus particles. Examples of pharmacologically acceptable salts of sufficiently basic compounds of the invention are salts of physiologically acceptable mineral acids like hydrochloric, hydrobromic, sulfuric and phosphoric acid; or salts of organic acids like methanesulfonic, p-toluenesulfonic, lactic, acetic, trifluoroacetic, citric, succinic, fumaric, maleic and salicylic acid. Further, a sufficiently acidic compound of the invention may form alkali or earth alkali metal salts, for example sodium, potassium, lithium, calcium or magnesium salts; ammonium salts; or organic base salts, for example methylamine, dimethylamine, trimethylamine, triethylamine, ethylenediamine, ethanolamine, choline hydroxide, meglumin, piperidine, morpholine, tris-(2- hydroxyethyl)amine, lysine or arginine salts; all of which are also further examples of salts of the invention. Compounds of the invention may be solvated, especially hydrated. The hydratization / hydration may occur during the process of production or as a consequence of the hygroscopic nature of the initially water free compounds of the invention. The solvates and / or hydrates may e.g. be present in solid or liquid form. It should be appreciated that certain compounds of the invention may have tautomeric forms from which only one might be specifically mentioned or depicted in the following description, different geometrical isomers (which are usually denoted as cis / trans isomers or more generally as (E) and (Z) isomers) or different optical isomers as a result of one or more chiral carbon atoms (which are usually nomenclatured under the Cahn-Ingold-Prelog or R / S system). All these tautomeric forms, geometrical or optical isomers (as well as racemates and diastereomers) and polymorphous forms are included in the invention. Since the compounds of the invention may contain asymmetric C-atoms, they may be present either as achiral compounds, mixtures of diastereomers, mixtures of enantiomers or as optically pure compounds. The present invention comprises both all pure enantiomers and all pure diastereomers, and also the mixtures thereof in any mixing ratio. According to a further embodiment of the present invention, one or more hydrogen atoms of the compounds of the present invention may be replaced by deuterium. Deuterium modification improves the metabolic properties of a drug with little or no change in its intrinsic pharmacology. Deuterium substitution at specific molecular positions improves metabolic stability, reduces formation of toxic metabolites and / or increases the formation of desired active metabolites. Accordingly, the present invention also encompasses the partially and fully deuterated compounds of the invention. The term hydrogen also encompasses deuterium. The therapeutic use of compounds according to the invention, their pharmacologically acceptable salts, solvates and hydrates, respectively, as well as formulations and pharmaceutical compositions also lie within the scope of the present invention. The pharmaceutical compositions according to the present invention may comprise at least one compound of the invention as an active ingredient and, optionally, carrier substances and / or adjuvants. The present invention also relates to prodrugs which are composed of a compound of the invention and at least one pharmacologically acceptable protective group which will be cleaved off under physiological conditions, such as an alkoxy-, arylalkyloxy-, acyl-, acyloxymethyl group (e.g. pivaloyloxymethyl), an 2-alkyl-, 2-aryl- or 2-arylalkyl oxycarbonyl-2-alkylidene ethyl group or an acyloxy group as defined herein, e.g. ethoxy, benzyloxy, acetyl or acetyloxy or, especially for a compound of the invention, carrying a hydroxy group (-OH): a sulfate, a phosphate (-OPO3 or -OCH2OPO3) or an ester of an amino acid. For example, compositions may contain pro-drugs of the hydroxy group of a compound of the invention. As used herein, the term pharmaceutically acceptable ester especially refers to esters which hydrolyze in vivo and include those that break down readily in the human body to leave the parent compound or a salt thereof. Suitable ester groups include, for example, those derived from pharmaceutically acceptable aliphatic carboxylic acids, particularly alkanoic, alkenoic, cycloalkanoic and alkanedioic acids, in which each alkyl or alkenyl moiety advantageously has not more than 6 carbon atoms. Examples of particular esters include, but are not limited to, formates, acetates, propionates, butyrates, acrylates and ethylsuccinates. The present invention also relates to a prodrug, a biohydrolyzable ester, a biohydrolyzable amide, a polymorph, tautomer, stereoisomer, metabolite, N-oxide, biohydrolyzable carbamate, biohydrolyzable ether, physiologically functional derivative, atropisomer, or in vivo-hydrolysable precursor, diastereomer or mixture of diastereomers, chemically protected form, affinity reagent, complex, chelate and a stereoisomer of the compounds of the invention. As mentioned above, therapeutically useful agents that contain compounds of the invention, their solvates, salts or formulations are also comprised in the scope of the present invention. In general, compounds of the invention will be administered by using the known and acceptable modes known in the art, either alone or in combination with any other therapeutic agent. For oral administration such therapeutically useful agents can be administered by one of the following routes: oral, e.g. as tablets, dragees, coated tablets, pills, semisolids, soft or hard capsules, for example soft and hard gelatin capsules, aqueous or oily solutions, emulsions, suspensions or syrups, parenteral including intravenous, intramuscular and subcutaneous injection, e.g. as an injectable solution or suspension, rectal as suppositories, by inhalation or insufflation, e.g. as a powder formulation, as microcrystals or as a spray (e.g. liquid aerosol), transdermal, for example via an transdermal delivery system (TDS) such as a plaster containing the active ingredient or intranasal. For the production of such tablets, pills, semisolids, coated tablets, dragees and hard, e.g. gelatin capsules, the therapeutically useful product may be mixed with pharmaceutically inert, inorganic or organic excipients as are e.g. lactose, sucrose, glucose, gelatine, malt, silica gel, starch or derivatives thereof, talc, stearinic acid or their salts, dried skim milk, and the like. For the production of soft capsules one may use excipients as are e.g. vegetable, petroleum, animal or synthetic oils, wax, fat, polyols. For the production of liquid solutions, emulsions or suspensions or syrups one may use as excipients e.g. water, alcohols, aqueous saline, aqueous dextrose, polyols, glycerin, lipids, phospholipids, cyclodextrins, vegetable, petroleum, animal or synthetic oils. Particularly useful are lipids, such as phospholipids (e.g., natural origin and / or with a particle size between 300 to 350 nm) in phosphate buffered saline (pH = 7 to 8, e.g., 7.4). For suppositories one may use excipients as are e.g. vegetable, petroleum, animal or synthetic oils, wax, fat and polyols. For aerosol formulations one may use compressed gases suitable for this purpose, as are e.g. oxygen, nitrogen and carbon dioxide. The pharmaceutically useful agents may also contain additives for conservation, stabilization, e.g. UV stabilizers, emulsifiers, sweetener, aromatizers, salts to change the osmotic pressure, buffers, coating additives and antioxidants. In general, in the case of oral or parenteral administration to adult humans weighing approximately 80 kg, a daily dosage of about 10 mg to about 10,000 mg, or from about 20 mg to about 1,000 mg, should be appropriate, although the upper limit may be exceeded when indicated. The daily dosage can be administered as a single dose or in divided doses, or for parenteral administration, it may be given as continuous infusion or subcutaneous injection. Methods of making compounds The invention also provides methods of making compounds of the invention, such as those described above. Synthesis schemes for making specific compounds of Formula (I) are provided in the Examples below. Methods of treating conditions The compounds and compositions of the invention modulate activity of one or more protein kinases. The compounds and compositions may inhibit, activate, or otherwise alter kinase activity.
