Description

[Technical field]

[0001] (Related Applications) This application claims priority to U.S. Provisional Application No. 62 / 883,264, filed August 6, 2019, which is incorporated by reference in its entirety. [Background technology]

[0002] The present invention generally relates to bicyclic heterocyclic compounds useful as kinase inhibitors, such as modulating IRAK4. The present invention provides bicyclic heterocyclic compounds, compositions containing the compounds, and methods of using them. The present invention further relates to pharmaceutical compositions containing at least one of the compounds described in the present invention, which are useful for treating conditions related to kinase modulation, and methods of inhibiting kinase activity (such as IRAK4 in mammals).

[0003] Toll / IL-1 receptor family members are key regulators of inflammation and host resistance. The Toll-like receptor (TLR) family recognizes molecular patterns derived from infectious organisms (e.g., bacteria, fungi, parasites, and viruses) (reviewed in Kawai, T. et al., Nature Immunol., 11:373-384 (2010)). Ligand binding to the receptor induces dimerization and recruitment of adaptor molecules to conserved cytoplasmic motifs in the receptor called Toll / IL-1 receptor (TIR) ​​domains. All TLRs except TLR3 recruit the adaptor molecule, MyD88. The IL-1 receptor family also contains a cytoplasmic TIR motif and recruits MyD88 upon ligand binding (reviewed in Sims, JE et al., Nature Rev. Immunol., 10:89-102 (2010)).

[0004] Members of the IRAK family of serine / threonine kinases are recruited to their receptors via interaction with MyD88. The family is composed of four members. Several lines of evidence have demonstrated that IRAK4 plays a critical and essential role in initiating signaling through MyD88-dependent TLR and IL-1R family members. Structural data confirm that IRAK4 directly interacts with MyD88 and then recruits either IRAK1 or IRAK2 to the receptor complex, facilitating downstream signaling (Lin, S. et al., Nature, 465:885-890 (2010)). IRAK4 directly phosphorylates IRAK1, facilitating downstream signaling to the E3 ubiquitin ligase TRAF6, which results in activation of the serine / threonine kinase TAK1 and subsequent activation of the NFκB pathway and MAPK cascade (Flannery, S. et al., Biochem. Pharmacol., 80:1981-1991 (2010)). A subset of human patients has been identified as lacking expression of IRAK4 (Picard, C. et al., Science, 299:2076-2079 (2003)). Cells from these patients are unresponsive to all TLR agonists except TLR3, as well as IL-1 family members such as IL-1β and IL-18 (Ku, C. et al., J. Exp. Med., 204:2407-2422 (2007)). Deletion of IRAK4 in mice resulted in a marked inhibition of IL-1, IL-18 and all TLR-dependent responses except TLR3 (Suzuki, N. et al., Nature, 416:750-754 (2002)).In contrast, deletion of either IRAK1 (Thomas, JA et al., J. Immunol., 163:978-984 (1999); Swantek, JL et al., J. Immunol., 164:4301-4306 (2000)) or IRAK2 (Wan, Y. et al., J. Biol. Chem., 284:10367-10375 (2009)) resulted in partial loss of signaling. Furthermore, IRAK4 is the only member of the IRAK family whose kinase activity has been shown to be required for initiation of signaling. Replacement of wild-type IRAK4 with a kinase-inactive mutant (KDKI) in the mouse genome attenuated signaling through all MyD88-dependent receptors, including IL-1, IL-18, and all TLRs except TLR3 (Koziczak-Holbro, M. et al., J. Biol. Chem., 282:13552-13560 (2007); Kawagoe, T. et al., J. Exp. Med., 204:1013-1024 (2007); and Fraczek, J. et al., J. Biol. Chem., 283:31697-31705 (2008)).

[0005] Compared to wild-type animals, mouse models of IRAK4 KDKI have demonstrated reduced risk of multiple sclerosis (Staschke, KA et al., J. Immunol., 183:568-577 (2009)), rheumatoid arthritis (Koziczak-Holbro, M. et al., Arthritis Rheum., 60:1661-1671 (2009)), atherosclerosis (Kim, TW et al., J. Immunol., 186:2871-2880 (2011) and Rekhter, M. et al., Biochem. Biophys. Res. Comm., 367:642-648 (2008)), and myocardial infarction (Maekawa, Y. et al., Circulation, 120:1401-1414 (2013)). (2009)) significantly reduced disease severity. As mentioned above, IRAK4 inhibitors block all MyD88-dependent signaling. MyD88-dependent TLRs have been shown to contribute to the pathogenesis of multiple sclerosis, rheumatoid arthritis, cardiovascular disease, metabolic syndrome, sepsis, systemic lupus erythematosus, inflammatory bowel disease (e.g., Crohn's disease and ulcerative colitis), autoimmune uveitis, asthma, allergy, type I diabetes, and allograft rejection (Keogh, B. et al., Trends Pharmacol. Sci., 32:435-442 (2011); Mann, DL, Circ. Res., 108:1133-1145 (2011); Horton, CG et al., Mediators Inflamm., Article ID 498980 (2010), doi:10.1155 / 2010 / 498980; Goldstein, DR et al., J. Heart Lung Transplant., 24:1721-1729 (2012)). (2005); and Cario, E., Inflamm. Bowel Dis., 16:1583-1597 (2010)). Oncogenically active MyD88 mutations in diffuse large B-cell lymphoma have been identified as sensitive to IRAK4 inhibition (Ngo, VN et al., Nature, 470:115-121 (2011)).Whole genome sequencing has also identified MyD88 mutations associated with chronic lymphocytic leukemia, suggesting that IRAK4 inhibitors may also be useful in treating leukemia (Puente, XS et al., Nature, 475:101-105 (2011)).

[0006] In addition to inhibiting TLR signaling, IRAK4 inhibitors also inhibit signaling by IL-1 family members. Neutralization of IL-1 has been shown to be effective against several diseases, such as gout; gouty arthritis; type 2 diabetes; autoinflammatory diseases (such as cryopyrin-associated periodic fever syndrome (CAPS), TNF receptor-associated periodic syndrome (TRAPS), familial Mediterranean fever (FMF), adult Still's disease, etc.); systemic juvenile idiopathic arthritis; stroke; graft-versus-host disease (GVHD); smoldering multiple myeloma; recurrent pericarditis; osteoarthropathy; and emphysema (Dinarello, CA, Eur. J. Immunol., 41:1203-1217 (2011) and Couillin, I. et al., J. Immunol., 183:8195-8202 (2009)). In a mouse model of Alzheimer's disease, inhibition of IL-1 receptor improved cognitive impairment, reduced tau pathology, and reduced amyloid-β oligomers (Kitazawa, M. et al., J. Immunol., 187:6539-6549 (2011)). IL-1 has also been shown to be closely related to adaptive immunity and to activate the differentiation of a subset of TH17 effector T cells (Chung, Y. et al., Immunity, 30:576-587 (2009)). Therefore, IRAK4 inhibitors are predicted to be effective against TH17-related diseases such as multiple sclerosis, psoriasis, inflammatory bowel disease, autoimmune uveitis, and rheumatoid arthritis (Wilke, CM et al., Trends Immunol., 32:603-661 (2011)).

[0007] Because symptoms can be ameliorated by treatments such as modulation of protein kinases, it is apparent that novel compounds capable of modulating protein kinases (e.g., IRAK4) and methods using these compounds may provide substantial therapeutic benefit to a wide range of patients.

In the methods of the present invention, the other therapeutic agents may be administered before, simultaneously, or after the administration of the compounds of the present invention. The present invention also provides pharmaceutical compositions capable of treating IRAK4 kinase-related conditions (e.g., TLR and IL-1 family receptor-mediated diseases described above).

[0086] The compositions of the present invention may contain and be formulated with other therapeutic agents as described above according to techniques well known to those skilled in the art of pharmaceutical formulation, for example, using conventional solid or liquid vehicles or diluents, as well as pharmaceutical excipients (e.g., additives, binders, preservatives, stabilizers, flavoring agents, and the like) of a type appropriate to the desired method of administration.

[0087] Accordingly, the present invention further includes compositions comprising one or more compounds of formula (I) and a pharma- ceutically acceptable carrier.

[0088] "Pharmaceutically acceptable carrier" refers to a medium generally accepted in the field of delivering biologically active agents to animals, particularly mammals. Pharmaceutically acceptable carriers are formulated according to many factors well within the expertise of those skilled in the art. These factors include, but are not limited to, the type and nature of the active agent being formulated, the patient to whom the composition containing the active agent will be administered, the intended route of administration of the composition, and the targeted therapeutic index. Pharmaceutically acceptable carriers include both aqueous and non-aqueous liquid media, as well as a variety of solid and semi-solid dosage forms. Such carriers can include many different components and additives in addition to the active agent, and such additional components are included in the formulation for a variety of reasons, such as for stabilization of the active agent, binders, and the like, known to those skilled in the art. Descriptions of suitable pharmacopoeia acceptable carriers and factors in selecting them can be found in a variety of readily available texts, such as Remington's Pharmaceutical Sciences, 17th Edition (1985), the entire contents of which are incorporated herein by reference.

[0089] The compounds according to formula (I) may be administered by any method appropriate to the condition to be treated, which may vary depending on the need for site-specific treatment or the amount of compound of formula (I) to be delivered.

[0090] The present invention also includes a class of pharmaceutical compositions comprising a compound of formula (I) and one or more non-toxic, pharma- ceutically acceptable carriers and / or diluents and / or adjuvants (substances collectively referred to herein as "carriers") and, optionally, other active ingredients. The compound of formula (I) may be administered by any suitable route, preferably in the form of a pharmaceutical composition adapted for such route, and in a dosage effective for the intended treatment. The compounds and compositions of the present invention may be administered, for example, orally, transmucosally, or parenterally, including intravascularly, intravenously, intraperitoneally, subcutaneously, intramuscularly, and intrasternally, in dosage unit formulations containing conventional pharma-ceutically acceptable carriers, adjuvants, and vehicles. For example, pharmaceutical carriers may include mixtures of mannitol or lactose and microcrystalline cellulose. The mixtures may include additional ingredients, such as lubricants (e.g., magnesium stearate) and disintegrants (e.g., crospovidone). The carrier mixture may be filled into gelatin capsules or compressed into tablets. The pharmaceutical composition may be administered, for example, in oral dosage form or as an infusion.

[0091] For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, capsule, liquid capsule, suspension, or liquid. The pharmaceutical composition is preferably formulated in a dosage unit form with a specific amount of active ingredient. For example, the pharmaceutical composition may be provided as a tablet or capsule containing an amount of active ingredient ranging from about 0.1 to 1000 mg, preferably from about 0.25 to 250 mg, more preferably from about 0.5 to 100 mg. The appropriate daily dose to be administered to a human or other mammal may vary widely depending on the patient's condition and other factors, but can be determined using routine methods.

[0092] Any pharmaceutical composition discussed herein can be delivered orally, for example, via any acceptable and suitable oral formulation. Examples of oral formulations include, but are not limited to, tablets, troches, lozenges, aqueous and oily suspensions, dispersible powders or granules, emulsions, hard and soft capsules, liquid capsules, syrups, and elixirs. Pharmaceutical compositions for oral administration can be prepared according to any method known in the art for preparing pharmaceutical compositions for oral administration.

[0099] At least one emulsion of the compound of formula (I) may be prepared, for example, as an oil-in-water emulsion. The oil phase of the emulsion containing the compound of formula (I) may be composed of known ingredients in a known manner. The oil phase may be provided, for example, but not limited to, vegetable oils (e.g., olive oil and peanut oil), mineral oils (e.g., liquid paraffin), and mixtures thereof. The oil phase may include only an emulsifier, but may also include a mixture of at least one emulsifier and a fat or oil, or both a fat and an oil. Suitable emulsifiers include, but are not limited to, naturally occurring phosphatides (e.g., soybean lecithin), esters or partial esters derived from fatty acids and hexitol anhydrides (e.g., sorbitan monooleate), and condensation products of partial esters and ethylene oxide (e.g., polyoxyethylene sorbitan monooleate). Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier that acts as a stabilizer. It is also preferred to include both an oil and a fat. Together, the emulsifier, with or without a stabilizer, makes up the so-called emulsifying wax, and the wax, with oils and fats, makes up the so-called emulsifying ointment base, which forms the oily dispersed phase of the cream formulation.The emulsion may also include sweeteners, flavorings, preservatives, and / or antioxidants.Emulsifiers and emulsion stabilizers suitable for use in the formulation of the present invention include Tween 60, Span 80, cetostearyl alcohol, myristyl alcohol, glyceryl monostearate, sodium lauryl sulfate, glyceryl distearate, alone or with wax; or other materials known in the art.

[0114] (Manufacturing method) The compounds of the present invention can be prepared by various methods well known to those skilled in the art of organic synthesis. The compounds of the present invention can be prepared using the methods described below and synthetic methods known in the art of organic chemical synthesis, or variations thereof that will be understood by those skilled in the art. Preferred methods include, but are not limited to, the following:

[0115] The reactions and techniques described in this section are carried out in solvents suitable for the reagents and materials used and are appropriate for the transformations effected. It is also understood that in the description of the synthetic methods described below, all reaction conditions presented (including the choice of solvent, reaction atmosphere, reaction temperature, experimental time and work-up method) are selected to be conditions that are standard for the reaction, which should be readily recognized by those skilled in the art. It is understood by those skilled in the art of organic synthesis that the functional groups present on various parts of the molecule must be compatible with the reagents and reactions presented. Such restrictions on the substituents compatible with the reaction conditions will be readily apparent to those skilled in the art, and alternative methods must be used. The reactions may require the decision to change the order of synthetic steps or to select a particular reaction sequence differently in order to obtain the desired compound of the invention. It is also recognized that another important consideration in planning any synthetic route in this field is the judicious selection of protecting groups used to protect reactive functional groups present in the desired compound described in the invention. For the experienced experimenter, an authoritative reference describing many protecting group alternatives is Protective Groups In Organic Synthesis by Greene et al. (Third Edition, Wiley & Sons, 1999).

[0116] Compounds of formula (I) may be prepared according to the methods outlined in the following schemes (e.g., Scheme 1). An appropriately substituted bromoaniline 1A may be reacted with diethyl 2-(ethoxymethylene)malonate in a solvent (e.g., toluene) and then further reacted in diphenyl ether at elevated temperature (e.g., reflux) to give the 6,6 bicyclic intermediate 1B. 1B may be reacted with a chlorinating reagent (e.g., POCl 3) to give derivatives such as 1C. Intermediate 1C may be reacted with various amines in the presence of a base to give compounds such as 1D. Intermediate 1D may be converted to acid 1E by reaction with an alkaline base such as NaOH in the presence of a solvent and water. Intermediate acid 1E may be converted to amide 1F by reaction with various amines under standard amide bond forming conditions. Finally, 1F may be reacted with various cross-coupling agents (e.g. boronic acids and esters) in the presence of a transition metal catalyst and a base to produce compounds of general formula I. [ka]

[0117] Certain compounds of formula I may also be prepared as outlined in Scheme 2. Utilizing intermediate 1D, the compound may be reacted with a variety of cross-coupling agents to form intermediates (e.g., 2B). The ester functionality of 2B may be converted to an acid by standard saponification methods (LiOH / THF / water) to give acid 2C. Intermediate 2C may then be reacted with a variety of imide acids in the presence of a coupling agent (e.g., Bop) to form coupling products which may then be reacted with hydrazine to give 1,2,4-triazole analogs (2-I). [ka]

[0118] Additionally, other compounds of formula I may be prepared as outlined in Scheme 3. Using 1D as starting material, the ester functionality may be converted to alcohol intermediate 3B by reaction with a reducing agent (e.g., DIBAL-H). After oxidation, aldehyde 3C may be obtained, which may be further converted to alkyne 3D. This alkyne intermediate may be used as a starting material for various heterocycles (e.g., isoxazoles and triazoles). For example, 3D may be reacted with hydroxyimidoyl chloride to form isoxazole intermediate 3E, which may be further reacted with a cross-coupling agent to obtain compounds of general formula I (3-IB in Scheme 3). Furthermore, alkyne 3D may be reacted with various alkyl azides to obtain 1,2,3-triazole intermediates (e.g., 3F). Furthermore, 3F may be reacted with an aryl cross-coupling agent to obtain other compounds of general formula I (3-IA in Scheme 3). [ka]

The methods and conditions used in these examples, and the actual compounds prepared in these examples, are not meant to be limiting, but are meant to illustrate how the compounds of the present invention may be prepared. The starting materials and reagents used in these examples are generally commercially available or reported in the chemical literature, or may be prepared by using steps described in the chemical literature, unless the preparation method is described herein. The present invention is further defined in the following examples, which should be understood to be given by way of illustration only. From the above discussion and examples, one skilled in the art will be able to ascertain the essential features of the present invention, and may make changes and modifications to adapt the present invention to a wide range of conditions and applications without departing from the spirit and scope of the invention. As a result, the present invention is not limited by the examples described below, but rather is defined by the claims appended hereto.

[0120] In the described examples, the phrase "dried and concentrated" generally refers to drying a solution in an organic solvent with either sodium sulfate or magnesium sulfate, followed by filtration and removal of the solvent from the filtrate (generally under reduced pressure and at a temperature appropriate to the stability of the material being prepared).
