Abstract
Description
Technical Field
[0001] The present invention provides compounds that modulate the activity of kinases, such as tyrosine kinase 2 (TYK2). Background Art
[0002] A wide variety of medical conditions that affect millions of people are caused or exacerbated by unregulated protein kinase activity. 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 diseases, eye diseases, infectious diseases, and hormone-related diseases. However, for many of these conditions, there are no effective inhibitors or activators for the specific kinase that causes the condition or its symptoms. As a result, patients continue to suffer from a range of conditions due to a lack of suitable drugs for their conditions. Summary of the invention
[0003] 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). Such an association is produced with the cytokine response mediated by signal transduction and activator of transcription (STAT) signal transduction. The JAK-STAT signal transduction pathway is an interaction chain between proteins in cells 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 leads to receptor dimerization, which brings the receptor-related JAKs into close proximity (Jalini et al., Genes and Cancer 2011), and triggers a series of downstream changes. There is a lot of evidence to prove the contribution of JAK-dependent cytokines to immunopathology, and clinical benefits can be provided by blocking these cytokines with biologics and small molecule inhibitors. Some examples of this are blocking IL-6 in rheumatoid arthritis or IL-12 / IL-23 in inflammatory bowel disease (IBD) (Schwartz et al. 2017).
[0004] The tyrosine kinase 2 (TYK2) member of the JAK family plays a specific role in 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 ( Figure 1Many of these pathways are altered in disease and drive chronic inflammation in IBD, psoriasis, and systemic lupus erythematosus (SLE) (Schwartz et al., Nat Rev Drug Dis, 2017).
[0005] In addition to the role of the TYK2 signaling cascade in disease, there is already strong genetic evidence pointing to a role for TYK2. Genetic association studies have linked the TYK2 locus to effects on susceptibility to SLE, psoriasis, and multiple sclerosis (MS). This identification has been replicated and expanded in many recent analyses, and TYK2 is now considered a susceptibility gene for a variety of inflammatory and autoimmune diseases, including type 1 diabetes (T1D). Common features of these diseases are alterations in immune function and activation, as well as downstream damage to target organs (Li et al., PLOS One, 2020).
[0006] The use of TYK2 small molecule inhibitors has confirmed several of these hypotheses. Previous work in human-derived PBMCs has demonstrated the ability of TYK2 inhibition to reduce IL-12 / IL-23 signaling in rodents and humans. TYK2 inhibition has also been shown to be effective in preclinical disease models of psoriasis and ulcerative colitis (Burke et al., Sci Trans Med, 2020). Preclinical effects in rodents have been applied to humans, showing the efficacy of deucravacitinib in patients with psoriasis (Armstrong et al., Ann of Rheu Dis, 2020). The genetic contribution of TYK2 has also been confirmed preclinically by using TYK2 knockout (KO) or transgenic (TG) animals. For example, type I interferon signaling is reduced in TYK2 KO animals 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). In summary, this large body of evidence provides supportive data for the role of cytokine signaling and supports the development of safe TYK2 inhibitors for a variety of inflammatory conditions.
[0007] The present invention provides compounds that modulate the activity of protein kinases associated with human diseases, disorders and conditions. In particular, the compounds of the present 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 associated with autoimmune diseases such as psoriasis, lupus, multiple sclerosis and inflammatory bowel disease. Therefore, embodiments of the present invention can be used as pharmaceutical compositions for treating such autoimmune disorders. The present invention also provides methods for using these compounds to modulate kinase activity in cells and treat disorders such as autoimmune disorders where modulating kinase activity provides therapeutic benefits.

[0359] Pharmaceutical composition
[0360] The present invention provides a pharmaceutical composition containing one or more of the above compounds or pharmaceutically acceptable esters, prodrugs, hydrates, solvates or salts of such compounds, optionally in combination with a pharmaceutically acceptable carrier. The present invention further provides such compounds for the preparation of drugs for treating one or more diseases mentioned herein.
[0361] The pharmaceutical composition may contain a therapeutically effective amount of one or more compounds of the present invention. The therapeutically effective amount of a compound according to the present invention refers to the amount of the compound that effectively prevents, alleviates or improves disease symptoms or prolongs the survival of the treated subject. The determination of a therapeutically effective amount is within the technical scope of the art.
[0362] The therapeutically effective amount or dosage of the compound according to the present invention can vary within a wide range and can be determined in a manner known in the art. This dosage can be adjusted according to the individual needs in each specific case, including the specific compound used, the route of administration, the disease treated, and the patient treated.
[0363] The compositions of the invention may include a vehicle for delivering one or more compounds of the invention. For example, the composition may contain particles, such as nanoparticles, microparticles, liposomes, micelles, and viral particles.
[0364] Examples of pharmacologically acceptable salts of sufficiently basic compounds of the present invention are salts of physiologically acceptable inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid and phosphoric acid; or salts of organic acids such as methanesulfonic acid, p-toluenesulfonic acid, lactic acid, acetic acid, trifluoroacetic acid, citric acid, succinic acid, fumaric acid, maleic acid and salicylic acid. In addition, sufficiently acidic compounds of the present invention can form alkali metal or alkaline earth metal salts, such as sodium salts, potassium salts, lithium salts, calcium salts or magnesium salts; ammonium salts; or organic base salts, such as methylamine, dimethylamine, trimethylamine, triethylamine, ethylenediamine, ethanolamine, choline hydroxide, meglumine, piperidine, morpholine, tri-(2-hydroxyethyl)amine, lysine or arginine salts; all of which are also further examples of salts of the present invention. The compounds of the present invention may be solvated, especially hydrated. Hydration / hydration may occur during the production process, or may occur due to the hygroscopicity of the initially anhydrous compound of the present invention. Solvates and / or hydrates may, for example, exist in solid or liquid form.
[0365] It should be understood that certain compounds of the present invention may have tautomeric forms (of which only one may be specifically mentioned or depicted in the following description), different geometric isomers (which are usually represented as cis / trans isomers or more generally as (E) and (Z) isomers) or different optical isomers (which are usually named under the Cahn-Ingold-Prelog or R / S system) due to one or more chiral carbon atoms. All of these tautomeric forms, geometric or optical isomers (as well as racemates and diastereomers) and polymorphic forms are included in the present invention. Since the compounds of the present invention may contain asymmetric C atoms, they may exist as non-chiral compounds, mixtures of diastereomers, mixtures of enantiomers or as optically pure compounds. The present invention includes all pure enantiomers and all pure diastereomers, as well as mixtures thereof in any mixing ratio.
[0366] According to another embodiment of the present invention, one or more hydrogen atoms of the compounds of this invention can be replaced by deuterium. Deuterium modification improves the metabolic characteristics of the drug, and its intrinsic pharmacology has little or no change. Deuterium substitution at specific molecular positions improves metabolic stability, reduces the formation of toxic metabolites and / or increases the formation of desired active metabolites. Therefore, the present invention also encompasses partially and fully deuterated compounds of the present invention. The term hydrogen also encompasses deuterium.
[0367] The therapeutic use of the compounds according to the present invention, their pharmacologically acceptable salts, solvates and hydrates, as well as preparations and pharmaceutical compositions are also within the scope of the present invention. The pharmaceutical composition according to the present invention may comprise at least one compound of the present invention as an active ingredient, optionally also comprising a carrier substance and / or an adjuvant.
[0368] The invention also relates to prodrugs consisting of a compound according to the invention and at least one pharmacologically acceptable protecting group which is cleaved off under physiological conditions, such as an alkoxy-, arylalkoxy-, acyl-, acyloxymethyl group (e.g. pivaloyloxymethyl), a 2-alkyl-, 2-aryl- or 2-arylalkyloxycarbonyl-2-alkyleneethyl group or an acyloxy group, such as ethoxy, benzyloxy, acetyl or acetoxy, or, in particular for compounds according to the invention carrying a hydroxyl group (-OH): a sulfate, a phosphate (-OPO) or a prodrug comprising a compound according to the invention and at least one pharmacologically acceptable protecting group which is cleaved off under physiological conditions, such as an alkoxy-, arylalkoxy-, acyl-, acyloxymethyl group (e.g. pivaloyloxymethyl) group, a 2-alkyl-, 2-aryl- or 2-arylalkyloxycarbonyl-2-alkyleneethyl group or an acyloxy group, such as ethoxy, benzyloxy, acetyl or acetoxy 3 or -OCH 2 OPO 3 ) or esters of amino acids. For example, the composition may contain a prodrug of a hydroxyl group of a compound of the invention.
[0369] As used herein, the term pharmaceutically acceptable ester refers in particular to esters that hydrolyze in vivo, and includes those esters that readily decompose 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 acids, olefinic acids, cycloalkanoic acids, and alkanedioic acids, wherein each alkyl or alkenyl moiety advantageously has no more than 6 carbon atoms.
