Abstract
Description
[Technical Field]
[0001] Application field of the invention The present invention relates to substituted 4H-pyrrolo[3,2-c]pyridin-4-one compounds, methods for their preparation and their use. [Background technology]
[0002] Background of the Invention The epidermal growth factor receptor (EGFR or EGF receptor) receptor tyrosine kinase family consists of four members: EGFR (Erbb1, Her1), ERBB2 (Her2), ERBB3 (Her3), and ERBB4 (Her4). EGFR mediates activation of MAPK and PI3K signaling pathways, thereby regulating cell proliferation, differentiation, migration, and survival (Pao et al., 2010). EGFR gene amplification, overexpression, and mutations are frequently observed in various cancer indications and are associated with poor prognosis (Gridelli et al., 2015).
[0003] In lung adenocarcinoma, EGFR mutations are prevalent in approximately 15% of Western patients and up to 50% of East Asian patients (Paez et al., 2004). These mutations typically occur in one of four exons, exons 18–21, in the kinase domain of EGFR (Paez et al., 2004). The most common activating mutations in EGFR are a point mutation in exon 21 substituting arginine for leucine (L858R) and a small in-frame deletion in exon 19 (del 19 / del746–750) that removes four amino acids (Pao et al., 2010). The FDA-approved inhibitors gefitinib, erlotinib, and afatinib targeting mutations in EGFR exons 18, 19, and 21 are effective in patients, but responses are often short-lived (Mok et al., 2009; Sequist et al., 2013). Resistance frequently develops in these patients in response to the acquisition of a second mutation, T790M (Pao et al., 2005). Second-generation inhibitors, such as afatinib, irreversibly target this mutation but remain potent inhibitors of wild-type EGFR, resulting in dose-limiting toxicity and a lack of efficacy in patients. Osimertinib, a third-generation irreversible inhibitor, maximizes activity against T790M while minimizing activity against wild-type EGFR, making it effective in patients with T790M mutations and currently the standard of care for T790M-positive patients (Mok et al., 2017). Osimertinib has also been approved as first-line treatment for patients with EGFR exon 19 or 21 mutations (Soria et al., 2018).
[0004] However, patients also acquire resistance to irreversible third-generation EGFR inhibitors, such as osimertinib. One of the major osimertinib resistance mechanisms identified is the mutation of cysteine to serine at position 797, resulting in the loss of the covalently interacting cysteine and loss of sensitivity to irreversible EGFR inhibitors, at which point patients who progress are currently left with limited treatment options (Thress et al., 2015; Oxnard et al., 2018). Such C797S mutations can also occur in the absence of T790M mutations, even when osimertinib is used as first-line treatment (Ramilingham et al., 2018a; Ramilingham et al., 2018b). Novel targeted therapies that can specifically address EGFR-C797S acquired resistance mutations would be highly beneficial for these patients.
[0005] In contrast, small in-frame insertions in EGFR exon 20, with the exception of A763_Y764insFQEA, are resistant to all clinically approved EGFR inhibitors at achievable doses in lung cancer patients, constituting an unmet medical need ( Yasuda et al., 2013 ).
[0006] Patients with EGFR exon 20 insertions, such as V769_D770insASV, D770_N771insSVD, D770_N771insNPG, N771_P772insH, H773_V774insH, H773_V774insNPH, and V774_C775insHV, exhibit significantly lower response rates to all currently approved EGFR-targeted therapies, resulting in significantly reduced progression-free survival and overall survival (Chen et al., 2016). This has been shown for first-generation inhibitors erlotinib and gefitinib, as well as the second-generation inhibitor afatinib (Chen et al., 2016; Yang et al., 2015).
[0007] Therefore, the standard of care for patients with EGFR exon 20 insertions is currently chemotherapy.
[0008] The same resistance profile has been observed for exon 20 insertion mutations in ERBB2 (e.g., ERBB2 A775_G776insYVMA, which has the highest prevalence), another member of the EGF receptor family ( Arcila et al., 2012 ), and some of the rarer EGFR mutations, such as L681Q ( Chiu et al., 2015 ).
[0009] Several irreversible EGFR exon 20 inhibitors are currently in clinical trials for the treatment of patients with EGFR exon 20 insertions: osimertinib, originally approved for the treatment of patients with T790M-mutant NSCLC (Floc'h et al., 2018); poziotinib (HM-781-36B), an unapproved pan-Hertz inhibitor targeting EGFR, Her2 / neu, and Her4 (Robichaux et al., 2018); and TAK-788 (AP32788) (Doebele et al., ASCO 2018). Initial clinical data have been published for poziotinib and TAK-788. Both compounds demonstrate clear clinical efficacy in patients with EGFR exon 20 insertions. However, major adverse events mediated by inhibition of wild-type EGFR have been reported in both clinical trials, which may limit their clinical utility.
[0010] More recently, new preclinical data have been published for two additional compounds showing activity against EGFR exon 20 insertions: TAS6417 (TCP-064) and compound 1a (Hasako et al., 2018; Jang et al., 2018). Clinical results for these two compounds are not yet available. [Prior art documents] [Non-patent literature]

[0012] In summary, mutant EGFR is a promising drug target for cancer treatment. In particular, patients who exhibit primary resistance to approved anti-EGFR therapies due to EGFR exon 20 insertions currently have few treatment options, and there is a great need for novel, alternative, and / or improved therapeutic agents to provide these patients with effective and tolerable treatments (Oxnard et al., 2013). Therefore, potent inhibitors of mutant EGFR, especially those harboring exon 20 insertion mutations that exhibit improved selectivity over wild-type EGFR, would be valuable compounds to complement treatment options either as single agents or in combination with other drugs.
[0013] The present invention provides compounds that inhibit mutant EGFR, in the presence or absence of the C797S mutation, specifically EGFR containing one or more exon 20 insertion mutations, L858R mutations, or small in-frame deletions of exon 19. These compounds further have reduced activity relative to wild-type EGFR.
[0014] The compounds of the present invention have been found to have surprising and advantageous properties.
[0015] In particular, the compounds of the present invention surprisingly inhibit mutant EGFR carrying exon 20 insertion mutations, particularly with an IC of less than 5 nM. 50These compounds were found to effectively inhibit mutant EGFR carrying the D770_N771ins SVD exon 20 insertion. Furthermore, these compounds were further found to exhibit differentiation potency of less than 1 μM in EGFR V769_D770insASV, D770_N771insSVD, D770_N771insNPG, N771_P772insH, or H773_V774insNPH exon 20 insertions, including the BA / F3 cell line. Furthermore, the compounds described herein are active in the BA / F3 cell line carrying D770_N771insSVD C797S. Additionally, the compounds described herein potently inhibit the growth of BA / F3 cell lines harboring EGFR activating mutations with or without the C797S acquired resistance mutation (EGFR E746_A750del, L858R, E746_A750del C797S, L858R C797S), a rare EGFR mutation (EGFR L681Q) or the ERBB2 exon 20 insertion A775_G776insYVMA.
[0016] Surprisingly, these compounds show at least 5-fold selectivity in anti-proliferation assays over the EGFR D770_N771ins SVD exon 20 insertion, including BA / F3 cell line, and wild-type EGFR, including BA / F3 cells, and therefore may be used for the treatment or prevention of diseases of uncontrolled cell proliferation, growth and / or survival, inappropriate cellular immune response, or uncontrolled cell proliferation, diseases involving proliferation and / or survival, inappropriate cellular immune response, or inappropriate cellular inflammatory response mediated by mutant EGFR with exon 20 insertion mutations and / or diseases that reduce (or block) proliferation in cells with EGFR exon 20 insertion mutations, such as hematological tumors, solid tumors, and / or metastases thereof, e.g., leukemia and myelodysplastic syndromes, malignant lymphomas, head and neck tumors, including brain tumors and brain metastases, thoracic tumors, including non-small cell and small cell lung tumors, gastrointestinal tumors, endocrine tumors, breast and other gynecological tumors, urological tumors, including kidney tumors, bladder tumors, and prostate tumors, skin tumors, and sarcomas, and / or metastases thereof.

[0049] Compounds of general formula (I) may exist as isotopic variations. Thus, the present invention includes one or more isotopic variations of compounds of general formula (I), particularly deuterium-containing compounds of general formula (I).
[0050] The term "isotopic variant" of a compound or reagent is defined as a compound that exhibits an unnatural proportion of one or more isotopes that constitute such compound.
[0051] The term "isotopic variant of a compound of general formula (I)" is defined as a compound of general formula (I) that exhibits unnatural proportions of one or more isotopes that constitute such compound.
[0052] The expression "unnatural proportion" should be understood to mean that the proportion of such isotope is higher than the natural abundance, and the natural abundance of an isotope as applied in this context is described in "Isotopic Compositions of Elements 1997", Pure Appl. Chem., 70(1), 217-235, 1998. Such isotopes include stable and radioactive isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine, bromine and iodine, for example, 2 H (deuterium), 3 H (tritium), 11 C. 13 C. 14 C. 15 N, 17 O. 18 O. 32 P, 33 P, 33 S, 34 S, 35 S, 36 S, 18 F, 36 Cl, 82 Br, 123 I, 124 I, 125 I, 129 I and 131 I.
[0053] For the treatment and / or prevention of the disorders identified herein, isotopic variants of compounds of general formula (I) in one embodiment contain deuterium ("deuterium-containing compounds of general formula (I)"). 3 H or 14 Isotopic variations of compounds of general formula (I) incorporating one or more radioactive isotopes, such as C, are useful, for example, in drug and / or substrate tissue distribution studies. These isotopes are particularly preferred for their ease of incorporation and detectability. 18 F or 11 Positron-emitting isotopes such as C may be incorporated into the compounds of general formula (I). These isotopic variants of the compounds of general formula (I) are useful for in vivo imaging applications. Deuterium-containing and 13C-containing compounds can be used for mass spectrometry analysis (HJ Leis et al., Curr. Org. Chem., 1998, 2, 131) in the context of preclinical or clinical trials.
[0054] Isotopic variants of compounds of general formula (I) can generally be prepared by methods known to those skilled in the art (e.g., those described in the schemes and / or examples herein) by substituting an isotopic variant of the reagent, in one embodiment, a deuterium-containing reagent. Depending on the desired site of deuteration, deuterium from DO can be incorporated directly into the compound or into a reagent useful for synthesizing such a compound (Esaki et al., Tetrahedron, 2006, 62, 10954; Esaki et al., Chem. Eur. J., 2007, 13, 4052). Deuterium gas is also a useful reagent for incorporating deuterium into molecules. Catalytic deuteration of olefinic bonds (H.J. Leis et al., Curr. Org. Chem., 1998, 2, 131; J.R. Morandi et al., J. Org. Chem., 1969, 34(6), 1889) and acetylenic bonds (H.H. Han, J. Am. Chem. Soc., 1952, 74(12), 3018; S. Chandrasekhar et al., Tetrahedron, 2011, 52, 3865) are rapid routes for deuterium incorporation. Metal catalysts (i.e., Pd, Pt, and Rh) in the presence of deuterium gas can be used to directly exchange hydrogen for deuterium in hydrocarbon-containing functional groups (J.G. Atkinson et al., U.S. Pat. No. 3,966,781). Various deuterated reagents and synthetic building blocks are commercially available from companies such as C / D / N Isotopes, Quebec, Canada; Cambridge Isotope Laboratories Inc., Andover, MA, USA; and CombiPhos Catalysts, Inc., Princeton, NJ, USA.Further information on the state of the art regarding deuterium-hydrogen exchange can be found, for example, in Hanzlik et al., J. Org. Chem. 55, 3992-3997, 1990; R.P. Hanzlik et al., Biochem. Biophys. Res. Commun. 160, 844, 1989; P.J. Reider et al., J. Org. Chem. 52, 3326-3334, 1987; M. Jarman et al., Carcinogenesis 16(4), 683-688, 1993; J. Atzrodt et al., Angew. Chem., Int. Ed. 2007, 46, 7744; K. Matoishi et al., J. Chem. Soc. Chem. Commun. 2000, 1519-1520; K. Kassahun et al., WO2012 / 112363.
[0055] The term "deuterium-containing compound of general formula (I)" is defined as a compound of general formula (I) in which one or more hydrogen atoms are replaced with one or more deuterium atoms, and the abundance of deuterium at each deuteration position of the compound of general formula (I) is greater than the natural abundance of deuterium (about 0.015%). In particular, in a deuterium-containing compound of general formula (I), the abundance of deuterium at each deuteration position of the compound of general formula (I) is greater than 10%, 20%, 30%, 40%, 50%, 60%, 70%, or 80%, and in one embodiment, greater than 90%, 95%, 96%, or 97%, and in another embodiment, greater than 98% or 99% at that position. It is understood that the abundance of deuterium at each deuteration position is independent of the abundance of deuterium at other deuteration positions.
[0056] The selective incorporation of one or more deuterium atoms into a compound of general formula (I) can alter the physicochemical properties (e.g., acidity [A. Streitwieser et al., J. Am. Chem. Soc., 1963, 85, 2759; C.L. Perrin et al., J. Am. Chem. Soc., 2007, 129, 4490], basicity [C.L. Perrin et al., J. Am. Chem. Soc., 2003, 125, 15008; C.L. Perrin in Advances in Physical Organic Chemistry, 44, 144; C.L. Perrin et al., J. Am. Chem. Soc., 2005, 127, 9641], lipophilicity [B. Testa et al., Int. J. Pharm., 1984, 19(3), 271]) and / or metabolic profile of the molecule, and can alter the ratio of metabolites to parent compounds or the amount of metabolites formed. Such changes can provide certain therapeutic benefits and may therefore be desirable in some situations. A decrease in the rate of metabolism and metabolic switching (changing the ratio of metabolites) has been reported (DJ Kushner et al., Can. J. Physiol. Pharmacol., 1999, 77, 79; AEMutlib et al., Toxicol. Appl. Pharmacol., 2000, 169, 102). These changes in exposure to parent drugs and metabolites can have important consequences for the pharmacodynamics, tolerability, and efficacy of deuterium-containing compounds of general formula (I). In some cases, deuterium substitution reduces or eliminates the formation of undesirable or toxic metabolites and enhances the formation of desirable metabolites (e.g., Nevirapine: AM Sharma et al., Chem. Res. Toxicol., 2013, 26, 410; Uetrecht et al., Chemical Research in Toxicology, 2008, 21, 9, 1862; Efavirenz: AEMutlib et al., Toxicol. Appl. Pharmacol., 2000, 169, 102). In other cases, the primary effect of deuteration is to decrease the rate of systemic clearance, thereby increasing the biological half-life of the compound.Potential clinical benefits would include the ability to maintain similar systemic exposure with reduced peak levels and increased trough levels. This may result in fewer side effects and enhanced efficacy, depending on the pharmacokinetic / pharmacodynamic relationship of the specific compound. Indiplon (AJ Morales et al., Abstract 285, The Journal of Clinical Oncology, Vol. 15, No. 15, 2015). th North American Meeting of the International Society of Xenobiotics, San Diego, CA, October 12-16, 2008), ML-337 (C.J. Wenthur et al., J.Med.Chem., 2013, 56, 5208), and odanacatib (K. Kassahun et al., WO2012 / 112363) are examples of this deuteration effect. Additional cases have been reported in which a decrease in metabolic rate results in increased drug exposure without altering the rate of systemic clearance (e.g., rofecoxib: F. Schneider et al., Arzneim.Forsch.Drug.Res., 2006, 56, 295; telaprevir: F. Maltais et al., J.Med.Chem., 2009, 52, 7993). Deuterated drugs that exhibit this effect may have reduced dosage requirements (e.g., fewer administrations or lower doses to achieve the desired effect) and / or may produce a lower metabolite burden.
[0057] The compound of general formula (I) may have multiple potential attack sites for metabolism. To optimize the above effects on physicochemical properties and metabolic profile, a deuterium-containing compound of general formula (I) with one or more specific patterns of deuterium-hydrogen exchange can be selected. In particular, the deuterium atoms of the deuterium-containing compound of general formula (I) are bonded to carbon atoms and / or to the cytochrome P of the compound of general formula (I), for example. 450 It is located in a position that is an attack site for metabolic enzymes such as
[0058] When plural forms of words such as compounds, salts, polymorphs, hydrates, solvates, etc. are used herein, this is understood to also mean a single compound, salt, polymorph, isomer, hydrate, solvate, etc.
[0059] By "stable compound" or "stable structure" is meant a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.
[0060] The compounds of the present invention may contain one or more asymmetric centers, depending on the location and nature of the various substituents desired. The asymmetric carbon atoms may be in the (R) or (S) configuration, resulting in a racemic mixture in the case of a single asymmetric center, and a diastereomeric mixture in the case of multiple asymmetric centers. In certain instances, asymmetry may also exist due to restricted rotation around a given bond, for example, the central bond adjacent to the two substituted aromatic rings of a particular compound.
[0061] Substituents on a ring may also be present in either the cis or trans form, and all such configurations (including enantiomers and diastereomers) are intended to be included within the scope of the present invention.
[0062] Preferred compounds are those that produce the more desirable biological activity. Also included within the scope of the present invention are separated, pure or partially purified isomers and stereoisomers or racemic or diastereomeric mixtures of the compounds of the present invention. Purification and separation of such materials can be accomplished by standard techniques known in the art.
[0063] Optical isomers can be obtained by resolving racemic mixtures according to conventional processes, for example, by the formation of diastereomeric salts or covalent diastereomers using optically active acids or bases. Examples of suitable acids are tartaric acid, diacetyltartaric acid, ditoluoyltartaric acid, and camphorsulfonic acid. Diastereomeric mixtures can be separated into their individual diastereomers based on their physical and / or chemical differences by methods known in the art, such as chromatography or fractional crystallization. The optically active base or acid is then liberated from the separated diastereomeric salts. Different methods for the separation of optical isomers include the use of chiral chromatography (e.g., chiral HPLC columns), with or without conventional derivatization, optimally selected to maximize the separation of the enantiomers. Suitable chiral HPLC columns are manufactured by Daicel (e.g., Chiracel OD and Chiracel OJ, among many others), and are all routinely selectable. Enzymatic separations, with or without derivatization, are also useful. The optically active compounds of this invention can likewise be obtained by chiral syntheses utilizing optically active starting materials.
[0064] For the purpose of limiting different types of isomers to one another, see IUPAC Rules Section E (Pure Appl Chem 45, 11-30, 1976).
[0065] The present invention includes all possible stereoisomers of the compounds of the present invention, either as a single stereoisomer or as any mixture of said stereoisomers, e.g., as R- or S-isomers, or E- or Z-isomers, in any ratio. Isolation of a single stereoisomer of a compound of the present invention, e.g., a single enantiomer or a single diastereomer, can be achieved by any suitable state-of-the-art method, such as, for example, chromatography, in particular chiral chromatography.
[0066] Furthermore, the compounds of the present invention may exist as tautomers. For example, any compound of the present invention containing a pyrazole moiety as a heteroaryl group can exist as, for example, a 1H tautomer, or a 2H tautomer, or a mixture of any amounts of the two tautomers, or a triazole moiety can exist as, for example, a 1H tautomer, a 2H tautomer, or a 4H tautomer, or a mixture of any amounts of the 1H, 2H, and 4H tautomers: [ka]

[0070] The compounds of the present invention can exist as hydrates or solvates, where the compounds of the present invention contain polar solvents, particularly water, methanol or ethanol, for example, as structural elements of the crystal lattice of the compounds. The amount of polar solvent, particularly water, can be in a stoichiometric or non-stoichiometric ratio. In the case of stoichiometric solvates, for example, hydrates, hemi-, semi-, mono-, sesqui-, di-, tri-, tetra-, penta-, etc., can be solvates or hydrates, respectively. The present invention includes all such hydrates or solvates.
[0071] Furthermore, the compounds of the present invention can exist in free form, for example as a free base, or as a free acid, or as a zwitterion, or can exist in the form of a salt, which can be either an organic or inorganic addition salt, in particular any pharmaceutically acceptable organic or inorganic addition salt conventionally used in pharmacy.
[0072] The term "pharmaceutically acceptable salts" refers to relatively non-toxic, inorganic or organic acid addition salts of compounds of the present invention. See, e.g., S. M. Berge et al., "Pharmaceutical Salts," J. Pharm. Sci. 1977, 66, 1-19.
[0073] Suitable pharmaceutically acceptable salts of the compounds of the present invention can be, for example, acid addition salts of compounds of the present invention having a nitrogen atom in the chain or ring, e.g., sufficiently basic, for example, acid addition salts with inorganic acids such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, bisulfuric acid, phosphoric acid or nitric acid, or acid addition salts with formic acid, acetic acid, acetic acid, pyruvic acid, trifluoroacetic acid, propionic acid, butyric acid, hexanoic acid, heptanoic acid, undecanoic acid, lauric acid, benzoic acid, salicylic acid, 2-(4-hydroxybenzoyl)-benzoic acid, camphoric acid, cinnamic acid, cyclopentanepropionic acid, digluconic acid, 3-hydroxy-2-naphthonic acid, nicotinic acid, pamoic acid, pectic acid, persulfate, 3-phenyl Acid addition salts with organic acids such as propionic acid, picric acid, pivalic acid, 2-hydroxyethanesulfonic acid, itaconic acid, sulfamic acid, trifluoromethanesulfonic acid, dodecylsulfuric acid, ethanesulfonic acid, benzenesulfonic acid, paratoluenesulfonic acid, methanesulfonic acid, 2-naphthalenesulfonic acid, naphthalenedisulfonic acid, camphorsulfonic acid, citric acid, tartaric acid, stearic acid, lactic acid, oxalic acid, malonic acid, succinic acid, malic acid, adipic acid, alginic acid, maleic acid, fumaric acid, D-gluconic acid, mandelic acid, ascorbic acid, glucoheptanoic acid, glycerophosphoric acid, aspartic acid, sulfosalicylic acid, hemisulfuric acid, and thiocyanic acid.
[0074] Further suitable pharmaceutically acceptable salts of compounds of the invention that are sufficiently acidic are alkali metal salts, such as sodium or potassium salts, alkaline earth metal salts, such as calcium or magnesium salts, ammonium salts, or salts with organic bases that provide physiologically acceptable cations, such as N-methyl-glucamine, dimethyl-glucamine, ethyl-glucamine, lysine, dicyclohexylamine, 1,6-hexadiamine, ethanolamine, glucosamine, sarcosine, serinol, tris-hydroxy-methyl-aminomethane, aminopropanediol, sovak's base, 1-amino-2,3,4-butanetriol. Additionally, basic nitrogen-containing groups may be quaternized with agents such as lower alkyl halides, e.g., methyl, ethyl, propyl, and butyl chlorides, bromides, and iodides; dialkyl sulfates, such as dimethyl, diethyl, and dibutyl sulfates; and diamyl sulfate, long chain halides, such as decyl, lauryl, myristyl, and stearyl chlorides, bromides, and iodides; and aralkyl halides, such as benzyl and phenethyl bromide.
[0075] Those skilled in the art will further recognize that acid addition salts of the claimed compounds can be prepared via any of a number of known methods by reacting the compounds with the appropriate inorganic or organic acid. Alternatively, alkali and alkaline earth metal salts of acidic compounds of the invention are prepared via a variety of known methods by reacting the compounds of the invention with the appropriate base.
[0076] The present invention includes all possible salts of the compounds of the present invention, either as single salts or as any mixture of said salts, in any proportion.
[0077] When compounds are referred to herein, particularly in the experimental part, for the synthesis of intermediates and examples of the present invention, as salt forms with corresponding bases or acids, the exact stoichiometry of said salt forms obtained by the respective preparation and / or purification process is in most cases unknown.
[0078] Unless otherwise specified, for example, "hydrochloride", "trifluoroacetate", "sodium salt", or "xHCl", "xCF3COOH", "xNa + A suffix to a chemical name or structural formula such as "" should be understood to simply refer to the salt form and not to a stoichiometric specification.
[0079] This also applies if the synthetic intermediates or example compounds or salts thereof are obtained by the described preparation and / or purification processes as solvates, such as hydrates, of unknown stoichiometry (if defined).
[0080] Salts include water-insoluble salts and particularly water-soluble salts.
[0081] Furthermore, derivatives of the compound of formula (I) and their salts (bioprecursors or prodrugs) that are converted to the compound of formula (I) or its salt in a biological system are encompassed by the present invention. The biological system is, for example, a mammalian organism, particularly a human subject. The bioprecursors are, for example, converted to the compound of formula (I) or its salt by metabolic processes.
[0082] As used herein, the term "in vivo hydrolyzable ester" is understood to mean an in vivo hydrolyzable ester of a compound of the present invention containing a carboxy or hydroxy group, for example, a pharmaceutically acceptable ester that is hydrolyzed in the human or animal body to produce the parent acid or alcohol. Suitable pharmaceutically acceptable esters for carboxy include, for example, alkyl, cycloalkyl, and optionally substituted phenylalkyl, particularly benzyl ester, C-C alkoxymethyl ester, for example, methoxymethyl, C-C alkanoyloxymethyl ester, for example, pivaloyloxymethyl, phthalidyl ester, C-C cycloalkoxycarbonyloxy-C-C alkyl ester, for example, 1-cyclohexylcarbonyloxyethyl, 1,3-dioxolen-2-onylmethyl ester, for example, 5-methyl-1,3-dioxolen-2-onylmethyl, and C-C alkoxycarbonyloxyethyl ester, for example, 1-methoxycarbonyloxyethyl, and may be formed at any carboxy group in the compound of the present invention.
[0083] In vivo hydrolyzable esters of the compounds of the present invention containing a hydroxy group include inorganic esters such as phosphate esters and [α]-acyloxyalkyl ethers, as well as related compounds that yield the parent hydroxy group as a result of in vivo hydrolysis of the ester decomposition. Examples of [α]-acyloxyalkyl ethers include acetoxymethoxy and 2,2-dimethylpropionyloxymethoxy. The in vivo hydrolyzable ester-forming groups selected for hydroxy include alkanoyl, benzoyl, phenylacetyl and substituted benzoyl and phenylacetyl, alkoxycarbonyl (yielding alkyl carbonate esters), dialkylcarbamoyl and N-(dialkylaminoethyl)-N-alkylcarbamoyl (yielding carbamates), dialkylaminoacetyl, and carboxyacetyl. The present invention encompasses all such esters.
[0084] Furthermore, the present invention includes all possible crystalline forms or polymorphs of the compounds of the present invention, either as a single polymorph or as a mixture of two or more polymorphs, in any proportion.
[0085] In the context of the properties of the compounds of the present invention, the term "pharmacokinetic profile" refers to one single parameter or a combination thereof, including pharmacodynamic parameters such as permeability, bioavailability, exposure, and duration, or the magnitude of pharmacological effect, as measured in appropriate experiments. A compound with an improved pharmacokinetic profile can, for example, be used at a lower dose to achieve the same effect, can achieve a longer duration of action, or can achieve a combination of both effects.
[0086] The term "combination" as used herein is used as known to those skilled in the art and may exist as a fixed combination, a loose combination, or a kit-of-parts.
[0087] The term "fixed combination" in the present invention is used as known to those skilled in the art and is defined as a combination in which the first active ingredient and the second active ingredient are present together in one unit dose or single entity. One example of a "fixed combination" is a pharmaceutical composition in which the first active ingredient and the second active ingredient are present in admixture for simultaneous administration, such as in a formulation. Another example of a "fixed combination" is a pharmaceutical combination in which the first active ingredient and the second active ingredient are present in one unit, not in admixture.
[0088] A "non-fixed combination" or "kit-of-parts" as used herein is used as known to those skilled in the art and is defined as a combination in which the first active ingredient and the second active ingredient are present in two or more units. An example of a non-fixed combination or kit-of-parts is a combination in which the first active ingredient and the second active ingredient are present separately. The components of a non-fixed combination or kit-of-parts may be administered separately, sequentially, simultaneously, concurrently, or chronologically staggered. Any such combination of a compound of formula (I) of the present invention with an anti-cancer agent as defined below is an embodiment of the present invention.

[0120] The compounds of the present invention can be isolated and purified in a manner known per se, for example, by vacuum distillation of the solvent and recrystallization of the resulting residue from a suitable solvent, or by one of the usual purification methods, such as chromatography on a suitable support material. Furthermore, reverse-phase preparative HPLC may be applied. Compounds of the present invention having sufficiently basic or acidic functionality can be converted into salts, such as trifluoroacetate or formate salts in the case of sufficiently basic compounds, or ammonium salts in the case of sufficiently acidic compounds. These types of salts can be converted into their free base or free acid forms, respectively, by various methods known to those skilled in the art, or can be used as salts in subsequent biological assays. Furthermore, the drying process during isolation of the compounds of the present invention may not completely remove traces of cosolvents, particularly formic acid or trifluoroacetic acid, to form solvates or inclusion complexes. Those skilled in the art will recognize which solvates or inclusion complexes are acceptable for use in subsequent biological assays. It is to be understood that the particular form (e.g., salt, free base, free acid, solvate, inclusion complex) of a compound of the invention isolated and described herein is not necessarily the only form in which said compound can be applied in a biological assay to determine a specific biological activity.
[0121] Salts of compounds of formula (I) according to the present invention can be obtained by dissolving the free compound in a suitable solvent (e.g., a ketone such as acetone, methyl ethyl ketone, or methyl isobutyl ketone; an ether such as diethyl ether, tetrahydrofuran, or dioxane; a chlorinated hydrocarbon such as methylene chloride or chloroform; or a low molecular weight aliphatic alcohol such as methanol, ethanol, or isopropanol) containing the desired acid or base or to which the desired acid or base is then added. The acids or bases can be used in the preparation of the salt in equimolar or different ratios, depending on whether a monobasic or polybasic acid or base is involved and which salt is desired. The salt can be obtained by filtering, reprecipitating, precipitating with a non-solvent for the salt, or by evaporating the solvent. The obtained salt can be converted into the free compound, which can then be converted into a salt. In this way, pharmaceutically unacceptable salts, for example, obtainable as process products in industrial-scale production, can be converted into pharmaceutically acceptable salts by processes known to those skilled in the art. Particularly preferred are hydrochloride salts and the methods used in the Examples section.
[0122] Pure diastereomers and pure enantiomers of the compounds and salts according to the invention can be obtained, for example, by asymmetric synthesis, by using chiral starting compounds in the synthesis or by resolving the enantiomeric and diastereomeric mixtures obtained in the synthesis.
[0123] Enantiomeric and diastereomeric mixtures can be resolved into pure enantiomers and pure diastereomers by methods known to those skilled in the art. In one embodiment, diastereomeric mixtures are separated by crystallization, particularly fractional crystallization, or chromatography. Enantiomeric mixtures can be separated, for example, by forming diastereomers using a chiral auxiliary, resolving the resulting diastereomers, and removing the chiral auxiliary. For example, chiral acids can be used as chiral auxiliary to separate enantiomeric bases, such as mandelic acid, and chiral bases can be used to separate enantiomeric acids by forming diastereomeric salts. Furthermore, diastereomeric derivatives, such as diastereomeric esters, can be formed from enantiomeric mixtures of alcohols or acids using chiral acids or chiral alcohols, respectively, as chiral auxiliary. Furthermore, diastereomeric complexes or diastereomeric clathrates can be used to separate enantiomeric mixtures. Alternatively, enantiomeric mixtures can be resolved using chiral separation columns in chromatography. Another suitable method for isolating enantiomers is enzymatic separation.

[0162] Methods for treating kinase disorders The present invention also provides methods for treating disorders associated with aberrant mitogenic extracellular kinase activity, including, but not limited to, stroke, heart failure, hepatomegaly, cardiac hypertrophy, diabetes, Alzheimer's disease, cystic fibrosis, conditions of xenograft rejection, septic shock, or asthma.
[0163] Effective amounts of the compounds of the invention can be used to treat such disorders, including those diseases (e.g., cancer) mentioned in the Background section above. Nevertheless, such cancers and other diseases can be treated with the compounds of the invention regardless of the mechanism of action and / or the relationship between the kinase and the disorder.
[0164] The term "aberrant kinase activity" or "aberrant tyrosine kinase activity" includes any abnormal expression or activity of the kinase-encoding gene or the polypeptide it encodes. Examples of such abnormal activity include, but are not limited to, overexpression of the gene or polypeptide; gene amplification; mutations that result in constitutively active or hyperactive kinase activity; gene mutations, deletions, substitutions, additions, etc.

[0166] Methods for treating angiogenic disorders The present invention also provides methods for treating disorders and diseases associated with excessive and / or aberrant angiogenesis.
[0167] Inappropriate and ectopic angiogenesis can be harmful to an organism. Many pathological conditions are associated with the growth of extraneous blood vessels. These include, for example, diabetic retinopathy, ischemic retinal vein occlusion, and retinopathy of prematurity [Aiello et al., New Engl. J. Med. 1994, 331, 1480; Peer et al., Lab. Invest. 1995, 72, 638], age-related macular degeneration [AMD; Lopez et al., Invest. Opthalmol. Vis. Sci. 1996, 37, 855], neovascular glaucoma, psoriasis, retrolental fibroplasia, angiofibroma, inflammation, rheumatoid arthritis (RA), restenosis, in-stent restenosis, and vascular graft restenosis. Furthermore, the increased blood supply associated with cancerous and neoplastic tissues promotes proliferation, leading to rapid tumor growth and metastasis. Furthermore, the growth of new blood and lymphatic vessels in tumors provides an escape route for rebel cells, promoting metastasis and the spread of cancer. Thus, the compounds of the present invention can be utilized to treat and / or prevent any of the above-mentioned angiogenic disorders, for example, by inhibiting and / or reducing angiogenesis; by inhibiting, blocking, reducing, decreasing, etc., endothelial cell proliferation or other types involved in angiogenesis, and by inducing cell death (e.g., apoptosis of such cell types).

[0183] The oils that can be used in the parenteral formulations of the present invention include oils of petroleum, animal, vegetable or synthetic origin, such as peanut oil, soybean oil, sesame oil, cottonseed oil, corn oil, olive oil, petroleum and mineral oil.Suitable fatty acids include oleic acid, stearic acid, isostearic acid and myristic acid.Suitable fatty acid esters include, for example, ethyl oleate and isopropyl myristate. Suitable soaps include alkali metal, ammonium, and triethanolamine salts of fatty acids, and suitable surfactants include cationic surfactants such as dimethyldialkylammonium halides, alkylpyridinium halides, and alkylamine acetates; anionic surfactants such as alkyl, aryl, and olefin sulfonates, alkyl sulfates, olefin sulfates, ether and monoglyceride sulfates, and sulfosuccinates; nonionic surfactants such as fatty amine oxides, fatty acid alkanolamides, and poly(oxyethylene-oxypropylene) or ethylene oxide or propylene oxide copolymers; and amphoteric surfactants such as quaternary ammonium salts of alkyl β-aminopropionates and 2-alkylimidazolines, and mixtures thereof.
[0184] The parenteral compositions of the present invention generally contain from about 0.5% to about 25% by weight of the active ingredient in solution. Preservatives and buffering agents may also be advantageously used. To minimize or eliminate injection site irritation, such compositions may, in one embodiment, contain a nonionic surfactant having a hydrophile-lipophile balance (HLB) of from about 12 to about 17. The amount of surfactant in such formulations, in one embodiment, ranges from about 5% to about 15% by weight. The surfactant may be a single component having the above HLB or a mixture of two or more components having the desired HLB.
[0185] Examples of surfactants used in parenteral formulations are the class of polyethylene sorbitan fatty acid esters, e.g., sorbitan monooleate, and high molecular weight adducts of ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol.
[0186] The pharmaceutical composition can be in the form of a sterile injectable aqueous suspension.This suspension can be prepared according to known methods using suitable dispersing or wetting agents and suspending agents, such as sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; natural phospholipids such as lecithin, condensation products of alkylene oxides and fatty acids, such as polyoxyethylene stearate, condensation products of ethylene oxide and long-chain aliphatic alcohols, such as heptadecaethyleneoxycetanol, condensation products of ethylene oxide and partial esters derived from fatty acids and hexitols, such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide and partial esters derived from fatty acids and hexitol anhydrides, such as polyoxyethylene sorbitan monooleate.

Diluents and solvents that can be used include, for example, water, Ringer's solution, isotonic sodium chloride solution, and isotonic glucose solution. In addition, sterile fixed oils are conventionally used as solvents or suspending media. For this purpose, any non-irritating fixed oil, including synthetic monoglycerides or diglycerides, can be used. In addition, fatty acids, such as oleic acid, can be used to prepare injectables.
[0188] The compositions of the present invention may also be administered in the form of suppositories for rectal administration of drugs. These compositions can be prepared by mixing the drug with a suitable non-irritating additive that is solid at room temperature but liquid at rectal temperature, and therefore melts in the rectum to release the drug. Such materials include, for example, cocoa butter and polyethylene glycol.
[0189] Controlled release formulations for parenteral administration include liposomal, polymeric microsphere and polymeric gel formulations known in the art.
[0190] It may be desirable or necessary to introduce pharmaceutical compositions into patients via mechanical delivery.The construction and use of mechanical delivery devices for drug delivery are well known in the art.Direct administration techniques, such as direct administration of drugs to the brain, usually involve placing a drug delivery catheter into the patient's ventricular system to bypass the blood-brain barrier.One such implantable delivery system used to transport drugs to specific anatomical regions of the body is described in U.S. Patent No. 5,011,472 (issued April 30, 1991).

[0215] Various aspects of the invention described in this application are illustrated by the following examples, which are not meant to limit the invention in any way.
[0216] The test experiments described herein serve to illustrate the invention, and the invention is not limited to the experiments given.
[0217] Experimental section - General section All reagents whose synthesis is not described in the experimental section are either commercially available, are known compounds, or can be formed from known compounds by known methods by those skilled in the art.
[0218] The compounds and intermediates produced according to the methods of the present invention may require purification. Purification of organic compounds is well known to those skilled in the art, and there may be several ways to purify the same compound. In some cases, purification may not be necessary. In some cases, compounds can be purified by crystallization. In some cases, impurities can be removed by trituration with an appropriate solvent. In some cases, compounds can be purified by chromatography, particularly flash column chromatography, using, for example, a Biotage automated purification system (SP4® or Isolera Four®) and a Biotage SNAP cartridge KP-Sil® or KP-NH® in combination with an eluent (e.g., a gradient of hexane / ethyl acetate or DCM / methanol). In flash column chromatography, unmodified ("normal") silica gel can be used, as well as amino-functionalized silica gel. In the experimental section, when referring to flash column chromatography or flash chromatography without specifying the stationary phase, normal silica gel was used.
[0219] In some cases, compounds can be purified by preparative HPLC using, for example, a Waters automated purifier equipped with a diode array detector and / or an online electrospray ionization mass spectrometer in combination with a suitable pre-packed reverse-phase column and eluent (e.g., a gradient of water and acetonitrile, which may contain additives such as trifluoroacetic acid, formic acid, or aqueous ammonia).
[0220] In some cases, the purification methods described above can provide compounds of the present invention having sufficiently basic or acidic functionalities in the form of a salt, such as a trifluoroacetate or formate salt in the case of a sufficiently basic compound of the present invention, or an ammonium salt in the case of a sufficiently acidic compound of the present invention. This type of salt can be converted to its free base or free acid form, respectively, by various methods known to those skilled in the art, or can be used as a salt in subsequent biological assays. It should be understood that the specific form (e.g., salt, free base, etc.) of a compound of the present invention isolated and described herein is not necessarily the only form in which the compound can be applied to biological assays to determine specific biological activity.

[0232] NMR spectrum: Given in the following paragraphs 1 The multiplicity of proton signals in H NMR spectra reflects the observed signal morphology and does not take into account any higher-order signal phenomena. As a rule, chemical shift data refer to the center of the signal in question. In the case of broad multiplets, a range is specified. Signals obscured by solvent or water are either tentatively assigned or not listed. Strongly broadened signals (e.g., caused by rapid rotation of molecular moieties or by proton exchange) are also tentatively assigned (often called broad multiplets or broad singlets) or not listed.
[0233] of selected compounds 1 H-NMR data is 1 The peaks are listed in the form of a H-NMR peak list, where for each signal peak, a δ value in ppm is given, followed by the signal intensity reported in parentheses. δ value-signal intensity pairs from different peaks are separated by commas. Thus, the peak list is: δ1 (intensity 1), δ2 (intensity 2), ..., δ i (strength i ), …, δ n (strength n ) in the general form
[0234] The intensity of a sharp signal correlates with the signal's height (cm) in the printed NMR spectrum. When compared to other signals, this data can be correlated with the actual ratio of signal intensities. For broad signals, two or more peaks, or signal centers, are shown along with their relative intensities compared to the most intense signal displayed in the spectrum. 1 The H-NMR peak list is a classic 1 It is similar to a H-NMR reading and therefore usually includes all peaks listed in a classical NMR interpretation. 1 Similar to a H-NMR printout, the peak list includes solvent signals, signals originating from stereoisomers of a particular target compound, impurity peaks,13 The peaks of the target compound may show C satellite peaks and / or spinning side bands. The peaks of the stereoisomers and / or impurities are typically shown at lower intensities (e.g., >90% purity) compared to the peaks of the target compound. Such stereoisomers and / or impurities are typical for a particular manufacturing process, and therefore, their peaks can be useful for identifying the reproduction of the manufacturing process based on "by-product fingerprints." The peaks of the target compound can be isolated by known methods (MestReC, ACD simulations, or using empirically evaluated expectation values), optionally using additional intensity filters, and such behavior is consistent with classical 1 This is similar to peak picking in H-NMR interpretation. A detailed description of reporting NMR data in the form of a peak list can be found in the publication "Citation of NMR Peaklist Data within Patent Applications" (see http: / / www.researchdisclosure.com / searching-disclosures, Research Disclosure Database Number 605005, 2014, 01 August 2014). In the peak picking routine, the parameter "MinimumHeight" can be adjusted between 1% and 4%, as described in Research Disclosure Database Number 605005. However, depending on the chemical structure and / or concentration of the compound being measured, it is reasonable to set the parameter "MinimumHeight" to <1%.

Potassium tert-butoxide (1.03 g, 9.14 mmol) was added, and the mixture was stirred at 0 °C for 1 h. The reaction mixture was slowly diluted with saturated ammonium chloride solution and extracted with EtOAc (3x). The organic phase was washed with brine, filtered through a water-repellent filter, concentrated under reduced pressure, and purified by flash chromatography (silica, hexane / EtOAc gradient 0-100%; EtOAc / EtOH gradient 0-35%) to give 1.18 g of the title compound (53% yield).
