[0001] KINASE MODULATORS AND METHODS OF USE THEREOF
[0002] Field of the Invention
[0003] The invention provides compounds that modulate the activity of kinases, such as Tyrosine Kinase 2 (TYK2).
[0004] Background
[0005] 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, multiple sclerosis, 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 sy mptoms. Consequently, patients continue to suffer from an array of disorders due to the lack of suitable medicaments for their conditions.
[0006] Summary
[0007] 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 pharmacal 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.

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 fonnation (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 lire 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 biologies 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).
[0109] 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 (SEE) (Schwartz et al, Nat Rev Drug Dis, 2017).
[0110] 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 SEE, 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, PEGS One. 2020).
[0111] 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 patients (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 Pl 104 protective variant of TYK2 are almost completely protected in the experimental autoimmune encephalitis (EAE) mouse model of MS (Gorman et al. Fmt in Immunology7, 2019). Together, this large body7of 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.
[0112] The invention provides compounds that modulate tire 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 treatinent 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.

[0270] The bromination reaction converts compound 1-1 to compound 1-2, followed by a nucleophilic substitution with compound IV- 1 to afford compound 1-3, which is deprotected to obtain compound I- 4.
[0271] Similarly, compound III- 1 is brominated to obtain compound III -2, followed by a nucleophilic substitution with compound IV- 1 to afford compound III-3, which undergoes a C-N coupling reaction to give compound III -4, a subsequent deprotection of compound III -4 then occurs to obtain diamine III- 5.
[0272] Starting from compound II-l, N-protection with SEMC1 obtains compound II-2, followed by an aromatic nucleophilic substitution with compound IV-2 to afford compound II-3, which is deprotected to give compound II -4.
[0273] With compounds 1-4 and II-4, a urea formation mediated by phenyl carbonochloridate is conducted to obtain compound V-l. followed by a reduction to give compound V-2. With the substrates III-5 and II-4. compound V-2 can also be synthesized through a urea formation mediated by phenyl carbonochloridate. The compound of formula A is derived from compound V-2 through an aromatic nucleophilic cyclization. In the case when ¥ is protected nitrogen (N-PG). a deprotection converts compound A to the compound of formula B.
[0274] In General Synthetic Scheme II, primary alcohol VI-1 is purchased from commercial sources or prepared according to the literature methods. A brief description of selected steps listed in the General Scheme II is provided herein.
[0275] Oxidation of alcohol VI- 1 to aldehyde VI -2, followed by an imine formation affords compound VI-3, which is reduced to compound VI-4. Deprotection of compound VI-4 leads to the formation of compound VI-5, which is brominated to obtain compound VI-6. The N protection converts compound VI-6 to compound VI-7, followed by a C-N coupling reaction to afford compound VI-8, which undergoes deprotection to afford diamine VI-9.
[0276] With compounds II-4 and VI-9, a urea formation mediated by pheny l carbonochloridate is conducted to obtain compound V-3, which is then converted to the compound of formula C through an aromatic nucleophilic cyclization. In the case when ¥ is protected nitrogen (N-PG), a further deprotection is needed to convert compound C to the compound of formula D.
