Description

[0001] HETEROBICYCLIC DERIVATIVES AS ITK INHIBITORS FIELD OF THE INVENTION The present invention relates to novel compounds having ITK inhibitory activity. This invention also relates to pharmaceutical compositions containing them, processes for their preparation and their use in the treatment of several disorders. BACKGROUND OF THE INVENTION ITK (interleukin-2-inducible T-cell kinase; also known as EMT or TSK) is a member of the TEC family of nonreceptor tyrosine kinases together with BTK, TEC, TXK, and BMX. The TEC-family kinases are characterized by a common domain organization consisting of an N-terminal pleckstrin-homology domain (PH) important for recruitment to the plasma membrane. Following the PH domain there is a proline-rich Tec homology region (TH) relevant for the protein activation state and the Src homology 2 (SH2) and 3 (SH3) domains that regulate protein-protein interactions. On the carboxy-terminal end lies the specific kinase catalytic domain. ITK is specially expressed in T lymphocytes, natural killer cells and mast cells. ITK is considered to be the predominant Tec kinase in T cells being a critical contributor to the strength of signal delivered by the T cell receptor (TCR). TCR stimulation leads to phosphorylation of associated cytoplasmic proteins, and accumulation of Phosphatidylinositol (3,4,5)-trisphosphate (PIP3) in the plasma membrane, leading to recruitment of ITK to the TCR signaling complex. ITK is then phosphorylated by LCK, triggering its autophosphorylation and full activation. Activated ITK subsequently phosphorylates and activates phospholipase C gamma 1 (PLC-γ1), leading to the generation of phosphatidylinositol 4,5-bisphosphate (PIP2) and diacylglycerol (DAG) that serve as second messengers. These phospholipid metabolites stimulate signaling via calcium mobilization, activation and translocation of transcription factors like AP-1, IRF4 and NFAT into the nucleus, induction of transcription and the production and release of relevant cytokines like IL-2, IL-4 and IL-17A among others. By modulating TCR signaling, ITK regulates multiple outcomes including cell activation, differentiation, proliferation, and function such as cytokine production in different subsets of T lymphocytes including Th1, Th2, Th17, T regulatory cells and CD8+Tcells. Considering the potential of ITK to modulate T cell function, numerous studies suggest that ITK could be involved in various inflammatory diseases and cancer. Regarding inflammatory diseases, ITK is increased in the skin of patients suffering from atopic dermatitis and also elevated levels of ITK were found in peripheral blood T cells. ITK - / - mice show reduced inflammation in models of acute contact hypersensitivity reactions and treatment with ITK inhibitor or using siRNA against ITK could also reduce inflammatory symptoms in mice. Evidences in allergic asthma show a contradictory role, as there are studies showing that ITK deficiency leads to less cell infiltration and less mucous production whereas other studies demonstrated that the loss has no beneficial effect and instead leading to T cell hyperplasia. In models of experimental autoimmune encephalomyelitis, which serves as a model for multiple sclerosis, depletion of ITK results in a diminished disease severity in mice with less transmigration of CD4+ cells into the central nervous system and across the brain endothelial barrier as well as reduced secretion of Th1 and Th17 effector cytokines. Potential involvement of ITK in oncogenesis has also been described. Inhibition of ITK may be beneficial for treatment of T-cell lymphoma. ITK is highly expressed and phosphorylated in in angioimmunoblastic T cell lymphoma and is a potential anti-cancer drug target. The ITK inhibitor CPI-818 shows preclinical anti-tumour activity and is currently in clinical trials in patients with relapsed / refractory T cell lymphoma. In view of the numerous conditions that are contemplated to benefit by treatment involving modulation of the ITK pathway or of the ITK kinase it is immediately apparent that new compounds that modulate ITK pathways and use of these compounds should provide substantial therapeutic benefits to a wide variety of patients. Several companies are developing ITK inhibitors, but many of these also target additional tyrosine kinases. For instance, ritlecitinib is a marketed small molecule that covalently and irreversibly inhibits Janus kinase 3 (JAK3) and the TEC family of kinases (BTK, BMX, ITK, TXK, and TEC). ATI-2138 is a dual ITK / JAK3 inhibitor currently in phase II clinical trials for the treatment of autoimmune and inflammatory diseases. Similarly, VIT-801 is a dual ITK / BTK inhibitor that is expected to begin clinical development soon. A key aspect in the field of ITK inhibitors is finding compounds with the required selectivity to ensure proper safety profile in a clinical setting. There remains the need for new effective and selective compounds that avoid inhibition of kinases such as JAK kinases that are associated in some cases with adverse effects such as infections, thrombosis and hematological, liver enzymes or lipids alterations among others.

DETAILED DESCRIPTION OF THE INVENTION When describing the compounds, compositions, combinations and methods of the present invention, the following terms have the following meanings, unless otherwise indicated. Definitions The term "therapeutically effective amount" refers to an amount sufficient to effect treatment when administered to a patient in need of treatment. The term "treatment" as used herein refers to the treatment of a disease or medical condition in a human patient which includes: (a) preventing the disease or medical condition from occurring, i.e., prophylactic treatment of a patient; (b) ameliorating the disease or medical condition, i.e., causing regression of the disease or medical condition in a patient; (c) suppressing the disease or medical condition, i.e., slowing the development of the disease or medical condition in a patient; or (d) alleviating the symptoms of the disease or medical condition in a patient. As used herein, the term “pharmaceutically acceptable salt” refers to a salt prepared from a base or acid which is acceptable for administration to a patient, such as a mammal. Such salts can be derived from pharmaceutically-acceptable inorganic or organic bases and from pharmaceutically-acceptable inorganic or organic acids. As used herein, a N-oxide is formed from the tertiary basic amines or imines present in the molecule, using a convenient oxidising agent. As used in the present invention, the term tautomer means two or more forms or isomers of an organic compound that readily could be interconverted into each other via a common chemical reaction called tautomerization. This reaction commonly results in the formal migration of a hydrogen atom or proton, accompanied by a switch of a single bond and adjacent double bond. The concept of tautomerizations is called tautomerism. Because of the rapid interconversion, tautomers are generally considered to be the same chemical compound. In solutions in which tautomerization is possible, a chemical equilibrium of the tautomers will be reached. The exact ratio of the tautomers depends on several factors, including temperature, solvent and pH. The compounds of the invention may exist in both unsolvated and solvated forms. The term solvate is used herein to describe a molecular complex comprising a compound of the invention and an amount of one or more pharmaceutically acceptable solvent molecules. The term hydrate is employed when said solvent is water. Examples of solvate forms include, but are not limited to, compounds of the invention in association with water, acetone, dichloromethane, 2-propanol, ethanol, methanol, dimethylsulfoxide (DMSO), ethyl acetate, acetic acid, ethanolamine, or mixtures thereof. The invention also includes isotopically-labelled compounds of the invention, wherein one or more atoms is replaced by an atom having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes suitable for inclusion in the compounds of the invention include isotopes of hydrogen, such as2H and3H, carbon, such as11C,13C and14C, chlorine, such as36CI, fluorine, such as18F, iodine, such as123I and125I, nitrogen, such as13N and15N, oxygen, such as15O,17O and18O, phosphorus, such as32P, and sulfur, such as35S. Preferred isotopically-labelled compounds include deuterated derivatives of the compounds of the invention. As used herein, the term deuterated derivative embraces compounds of the invention where in a particular position at least one hydrogen atom is replaced by deuterium. Deuterium (D or2H) is a stable isotope of hydrogen which is present at a natural abundance of 0.015 molar %. Isotopically-labelled compounds derivatives of the invention can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described herein, using an appropriate isotopically-labelled reagent in place of the non-labelled reagent otherwise employed. In the case of compounds of the invention that are solids, it is understood by those skilled in the art that the inventive compounds and salts may exist in different crystalline or polymorphic forms, or in an amorphous form, all of which are intended to be within the scope of the present invention. Compounds of the present invention containing one or more chiral centre may be used in enantiomerically or diastereoisomerically pure form, or in the form of a mixture of isomers. As used herein, unknown configurations of a chiral center are denoted by the configurational descriptors R* or S*. An example of such notation would be (R*)-1-(4-((5- (tetrahydro-2H-pyran-4-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)-2- azabicyclo[3.1.1]heptan-2-yl)prop-2-en-1-one, wherein (R*) means that the configuration of the chiral center present in the compound is unknown, being R or S, in this case arbitrarily denoted as R, as opposed to (S*)-1-(4-((5-(tetrahydro-2H-pyran-4-yl)-7H-pyrrolo[2,3- d]pyrimidin-4-yl)amino)-2-azabicyclo[3.1.1]heptan-2-yl)prop-2-en-1-one, which has the inverse configuration at same position. In case that more than one chiral center is present, the configurational descriptors R* or S* in each chiral center are assigned independently from one another. An example of such situation would be 1-((3S,5R)-3-methyl-5-((3-((2R*,4R*)-2-methyltetrahydro-2H-pyran-4- yl)-1H-pyrrolo[2,3-b]pyridin-4-yl)oxy)piperidin-1-yl)prop-2-en-1-one, wherein (2R*,4R*) means that both chiral centers at the C2 and at the C4 position of the tetrahydropyrane ring are unknown, being each of them either R or S independently. In this same example, the chiral centers at the C3 and C5 positions of the piperidine ring are known to be S and R respectively.

Within the oral mucosal cavity, delivery of drugs is classified into three categories: (a) sublingual delivery, which is systemic delivery of drugs through the mucosal membranes lining the floor of the mouth, (b) buccal delivery, which is drug administration through the mucosal membranes lining the cheeks (buccal mucosa), and (c) local delivery, which is drug delivery into the oral cavity. Pharmaceutical products to be administered via the oral mucosal can be designed using mucoadhesive, quick dissolve tablets and solid lozenge formulations, which are formulated with one or more mucoadhesive (bioadhesive) polymers and / or oral mucosal permeation enhancers. iv) Inhaled administration The heterobicyclic derivatives of the invention can also be administered by inhalation, typically in the form of a dry powder from a dry powder inhaler or as an aerosol spray from a pressurized container, pump, spray, atomizer (preferably an atomizer using electrohydrodynamics to produce a fine mist), or nebulizer, with or without the use of a suitable propellant. v) Nasal mucosal administration The heterobicyclic derivatives of the invention may also be administered via the nasal mucosal. Typical compositions for nasal mucosa administration are typically applied by a metering, atomizing spray pump and are in the form of a solution or suspension in an inert vehicle such as water optionally in combination with conventional excipients such as buffers, anti-microbials, tonicity modifying agents and viscosity modifying agents vi) Parenteral Administration The heterobicyclic derivatives of the invention may also be administered directly into the blood stream, into muscle, or into an internal organ. Suitable means for parenteral administration include intravenous, intraarterial, intraperitoneal, intrathecal, intraventricular, intraurethral, intrasternal, intracranial, intramuscular and subcutaneous. Suitable devices for parenteral administration include needle (including microneedle) injectors, needle-free injectors and infusion techniques. Parenteral formulations are typically aqueous solutions which may contain excipients such as salts, carbohydrates and buffering agents (preferably to a pH of from 3 to 9), but, for some applications, they may be more suitably formulated as a sterile non- aqueous solution or as a dried form to be used in conjunction with a suitable vehicle such as sterile, pyrogen-free water. The preparation of parenteral formulations under sterile conditions, for example, by lyophilization, may readily be accomplished using standard pharmaceutical techniques well known to those skilled in the art. The solubility of compounds of the invention used in the preparation of parenteral solutions may be increased by the use of appropriate formulation techniques, such as the incorporation of solubility-enhancing agents. vii) Rectal / lntravaginal Administration The heterobicyclic derivatives of the invention may be administered rectally or vaginally, for example, in the form of a suppository, pessary, or enema. Cocoa butter is a traditional suppository base, but various alternatives may be used as appropriate. Formulations for rectal / vaginal administration may be formulated to be immediate and / or modified release. Modified release formulations include delayed-, sustained-, pulsed-, controlled-, targeted and programmed release. viii) Ocular Administration The heterobicyclic derivatives of the invention may also be administered directly to the eye or ear, typically in the form of drops of a micronized suspension or solution in isotonic, pH- adjusted, sterile saline. Other formulations suitable for ocular and aural administration include ointments, biodegradable {e.g. absorbable gel sponges, collagen) and nonbiodegradable (e.g. silicone) implants, wafers, lenses and particulate or vesicular systems, such as niosomes or liposomes. Such formulations may also be delivered by iontophoresis. Formulations for ocular / aural administration may be formulated to be immediate and / or modified release. Modified release formulations include delayed-, sustained-, pulsed-, controlled-, targeted, or programmed release. The amount of the heterobicyclic derivative of the invention administered will be dependent on the subject being treated, the severity of the disorder or condition, the rate of administration, the disposition of the compound and the discretion of the prescribing physician. However, an effective dosage is typically in the range of 0.01-3000 mg, more preferably 0.5-1000 mg of active ingredient or the equivalent amount of a pharmaceutically acceptable salt thereof per day. Daily dosage may be administered in one or more treatments, preferably from 1 to 4 treatments, per day. Preferably, the pharmaceutical compositions of the invention are made up in a form suitable for oral or topical administration, being particularly preferred oral administration. The amount of each active which is required to achieve a therapeutic effect will, of course, vary with the particular active, the route of administration, the subject under treatment, and the particular disorder or disease being treated.

Alternatively, compounds of Formula (Vb) can be treated with carboxylic acids of Formula (VIb) in the presence of a suitable coupling agent such as HATU or HBTU or T3P or HOBT to give compounds of Formula (Ib)

[0007] Scheme 6 As illustrated in Scheme 6, in the particular case where in the formula (Y)nthe value of n equals 0, compounds of Formula (IB) may be treated with amines of Formula (IVc) in the presence of a suitable base such as cesium carbonate or triethylamine or diisopropylethylamine in a suitable solvent such as acetonitrile or dimethylsulfoxide or ethanol or butanol or N-N-dimethylacetamide at a temperature ranging from 60-180 ºC with or without the use of microwave irradiation to give compounds of Formula (Vc). Alternatively, compounds of Formula (IB) may be treated with amines of Formula (IVc) under Buchwald-Hartwig amination conditions, in the presence of a suitable catalyst such as palladium (II) acetate or tetrakis(triphenylphosphine) palladium (0) in the presence of a ligand such as XantPhos or XPhos and a suitable base such as cesium carbonate in a suitable solvent such as dioxane to give compounds of Formula (Vc). Compounds of Formula (Vc) can then be treated with acyl chlorides of Formula (VIa) in the presence of a suitable base such as triethylamine or diisopropylethylamine in a suitable solvent such as dichloromethane at a temperature ranging from -20 to 60 ºC to give compounds of Formula (Ic). Alternatively, compounds of Formula (Vc) can be treated with carboxylic acids of Formula (VIb) in the presence of a suitable coupling agent such as HATU or HBTU or T3P or HOBT to give compounds of Formula (Ic)

[0008] Scheme 7 Alternatively, as illustrated in Scheme 7, in the particular case where in the formula (Y)nthe value of n equals 0, compounds of Formula (IB) may be treated with boronic acids or boronic esters of Formula (IVd) under Suzuki–Miyaura reaction conditions (Miyaura, N.; Suzuki, A.

Such reactions may be catalyzed by a suitable palladium catalyst such as [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) or tris(dibencylidenoacetone)dipalladium (0) in a solvent such as dioxane or dimethoxyethane or toluene or N,N’-dimethylformamide with or without water as a cosolvent, in the presence of a base such as cesium carbonate or sodium carbonate or potassium phosphate, at temperatures ranging from 60-140 ºC with or without the use of microwave irradiation to give compounds of Formula (Vd1). Compounds of Formula (Vd1) can then be reduced with hydrogen at a pressure between atmospheric pressure and 60 psi in the presence of a suitable catalyst such as palladium on carbon or platinum (IV) oxide or Nickel-Raney in a suitable solvent such as methanol or tetrahydrofurane or ethyl acetate or a mixture of them at a temperature between room temperature and 50 ºC to give compounds of Formula (Vd2). Compounds of Formula (Vd2) can then be treated with acyl chlorides of Formula (VIa) in the presence of a suitable base such as triethylamine or diisopropylethylamine in a suitable solvent such as dichloromethane at a temperature ranging from -20 to 60 ºC to give compounds of Formula (Id). Alternatively, compounds of Formula (Vd2) can be treated with carboxylic acids of Formula (VIb) in the presence of a suitable coupling agent such as HATU or HBTU or T3P or HOBT to give compounds of Formula (Id). Scheme 8 Alternatively, compounds of Formula (V) may be prepared as illustrated in Scheme 8 from dihalogenated compounds of Formula (X) by reaction with amines or alcohols of Formula (IV) in the presence of a suitable base and in a suitable solvent to give compounds of Formula (XI). Compounds of Formula (XI) may be reacted with boronic acids or boronic esters of Formula (XIa) under Suzuki–Miyaura reaction conditions (Miyaura, N.; Suzuki, A. Chem. Rev.1995, 95, 2457). Such reactions may be catalyzed by a suitable palladium catalyst such as [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) or tris(dibencylidenoacetone)dipalladium (0) in a solvent such as dioxane or dimethoxyethane or toluene or N,N’-dimethylformamide with or without water as a cosolvent, in the presence of a base such as cesium carbonate or sodium carbonate or potassium phosphate, at temperatures ranging from 60-140 ºC with or without the use of microwave irradiation to give compounds of Formula (XII). Compounds of Formula (XII) can then be reduced with hydrogen at a pressure between atmospheric pressure and 60 psi in the presence of a suitable catalyst such as palladium on carbon or platinum (IV) oxide or Nickel-Raney in a suitable solvent such as methanol or tetrahydrofurane or ethyl acetate or a mixture of them at a temperature between room temperature and 50 ºC to give compounds of Formula (V).

Alternatively compounds of Formula (XI) can also be transformed directly into compounds of Formula (V) via a photochemical reaction by treatment with bromides of Formula (XIIIc) in the presence of a suitable catalyst such as [4,4′-Bis(1,1-dimethylethyl)-2,2′- bipyridine-N1,N1′]bis[3,5-difluoro-2-[5-(trifluoromethyl)-2-pyridinyl-N]phenyl- C]Iridium(III) hexafluorophosphate and [4,4′-bis(1,1-dimethylethyl)-2,2′-bipyridine] nickel (II) dichloride in the presence of a suitable reagent such as bis(trimethylsilyl)silyl- trimethylsilane and a base such as 2,6-dimethylpyridine in a solvent such as 1,2- dimethoxyethane under irradiation of visible light at wavelenght typically between 380 nm and 430 nm.

[0010] Scheme 10 Compounds of Formula (II) can also be prepared directly from compounds of Formula (X) as illustratedin Scheme 10 via a photochemical reaction, by treatment of compounds of Formula (X) with carboxylic acids of Formula (XIIIa) or carboxylic acid derivatives of Formula (XIIIb) in the presence of a suitable Nickel catalyst such as [4,4′-bis(1,1- dimethylethyl)-2,2′-bipyridine] nickel (II) dichloride and a suitable base such as sodium hydrogen carbonate in a suitable solvent such as N,N-dimethylacetamide and under irradiation of visible light at wavelenght typically between 380 nm and 430 nm. Alternatively, compounds of Formula (X) can also be transformed directly into compounds of Formula (II) via a photochemical reaction by treatment with bromides of Formula (XIIIc) in the presence of a suitable catalyst such as [4,4′-Bis(1,1-dimethylethyl)-2,2′- bipyridine-N1,N1′]bis[3,5-difluoro-2-[5-(trifluoromethyl)-2-pyridinyl-N]phenyl- C]Iridium(III) hexafluorophosphate and [4,4′-bis(1,1-dimethylethyl)-2,2′-bipyridine] nickel (II) dichloride in the presence of a suitable reagent such as Bis(trimethylsilyl)silyl- trimethylsilane and a base such as 2,6-dimethylpyridine in a solvent such as 1,2- dimethoxyethane under irradiation of visible light at wavelenght between 380 nm and 430 nm. In any step of the synthetic sequences described above, any reactant and intermediate can be used in a protected form to prevent certain functional groups from undergoing undesired reactions. In these cases, standard methods for the introduction and subsequent removal of these protecting groups can be used at any suitable step of the synthesis. Numerous protecting groups, their introduction and their removal are described in T. W. Greene and G. M. Wuts, Protecting Groups in Organic Synthesis, Third Edition, Wiley, New York, 1999, and references cited therein. In the cases where the above-described processes for the preparation of the compounds of this invention gives mixtures of stereoisomers, these stereoisomers may be separated at any convenient step of the synthetic route. In particular, the single enantiomers of racemic mixtures obtained during the synthesis may be separated by conventional techniques such as chiral chromatography, in particular, chiral HPLC and superfluid chromatography (SFC). This separation may take place at the final step of the synthetic sequence or at any intermediate stage of the synthesis, yielding enantiomerically pure intermediates that may be further transformed into the final products of the synthetic route. When more than one stereocenter is present in the molecules, mixtures of diastereomers may be obtained during the process of preparation of the compounds of this invention. In these cases, the use of conventional purification techniques may conduct to the isolation of single isomers or to the obtention of mixtures of two or more diastereomers, not necessarily in the same proportion. The syntheses of the compounds of the invention are illustrated by the following Examples (1 to 296) including Intermediates (1 to 27) and are given to provide a person skilled in the art with a sufficiently clear and complete explanation of the present invention but should not be considered as limiting of the essential aspects of its subject, as set out in the preceding portions of this description. Starting compounds are commercially available or may be obtained following the conventional synthetic methods already known in the art.
