Technical Field
[0002] The present invention relates to novel substituted bicyclic derivatives capable of selectively inhibiting the phosphorylation of myosin light chain mediated by ROCK2 and / or Rho kinase, methods for preparing the same, formulations thereof, and their use for the manufacture of pharmaceuticals, as well as pharmaceutically acceptable salts, diastereomers, enantiomers, and racemates.
Background Art
[0003] Rho-related coiled-coil protein kinases (ROCKs / Rho kinases / Rho-associated kinases) are downstream effectors of the small GTPase Rho (Rho A, Rho B, Rho C, and Rho E) and belong to the serine / threonine kinase family. Active GTP-bound Rho mediates several biological functions, including smooth muscle contraction, cell motility, and cell division, through the action of ROCKs. ROCK proteins were identified in 1996 as proteins that bind to Rho GTPases. Two proteins were isolated independently as p160 and p164. Later, these were recognized as ROCK-1 and ROCK-2, respectively, and were found to be isoforms of Rho-associated kinases. The two isoforms, ROCK-1 (ROCK-b / p160) and ROCK-2 (ROCK-a / p164), share 92% homology in their amino acid sequences. These structures consist of a catalytic kinase domain located at the N-terminus, a coiled-coil region (600 amino acids) followed by a Rho-binding domain, and a plextrin homology (PH) domain at the C-terminus. They are expressed in different sites, and distinct physiological roles have been identified for each. ROCK-1 transcript (a gene on chromosome 18) is widely expressed throughout the body, particularly prominently in the liver, kidneys, spleen, testes, thymus, and blood cells, while ROCK-2 mRNA (on chromosome 2) is more abundantly expressed in skeletal muscle and the brain, suggesting specialized roles in these regions.
[0004] ROCK inhibitors have been investigated for use in numerous diseases, including cerebral ischemia, hypertension, erectile dysfunction, glaucoma, osteoporosis, cardiac hypertrophy, diabetic cardiomyopathy, retinopathy, pulmonary hypertension, and atherosclerosis. However, their practical application is limited due to a lack of knowledge regarding the involvement of specific ROCK isoforms. It remains unclear whether isoform-specific targeting or inhibition of ROCK as a whole leads to superior therapeutic effects. Despite incomplete specificity to ROCK isoforms, as well as incomplete specificity to other serine / threonine kinases such as PRK2, PKC, cAMP-dependent protein kinases, and citron kinase, some nonspecific ROCK2 inhibitors have shown promising results in certain conditions such as glaucoma and hypertension. However, although some research-based findings have elucidated many unknowns regarding the specific functions of ROCK1 and ROCK2, further research is needed before isoform-selective ROCK2 inhibitors can be clinically used. Since ROCK plays a central role in the organization of the actin cytoskeleton, complete inhibition of both isoforms is likely to cause adverse events in patients. Therefore, selective inhibition of ROCK2 may have a higher specificity index than dual inhibition of ROCK1 and ROCK2. Thus, understanding the individual functions of each isoform in specific diseases will help improve safety and specificity, as well as expand the therapeutic range of ROCK inhibitors.

[0018] In this disclosure, the articles "a" and "an" are used to indicate that the grammatical object of the article is one or more (i.e., at least one). For example, "an element" means one or more elements.
[0019] In this disclosure, the term "and / or" means either "and" or "or" unless otherwise specified. The term "or" means "and / or" unless it explicitly refers to an option only or the options are mutually exclusive, but this disclosure supports both the definition referring to an option only and the definition referring to "and / or".
[0020] "Optional" or "optionally" means that the event or situation described thereafter may or may not occur, and the description includes both the cases in which such event or situation occurs and the cases in which it does not. For example, "optionally substituted aryl" includes both "aryl" and "substituted aryl" as defined herein. Those skilled in the art will understand that there is no intention to introduce any substitution or substitution pattern for any group containing one or more substituents that is sterically unrealizable, synthetically impractical, and / or inherently unstable.
[0021] Unless otherwise specified, the term “optionally substituted” means that the group is either unsubstituted or substituted with one or more of the substituents listed for that group (e.g., 0, 1, 2, 3, 4, or 5 or more, or any number derivable therefrom), and these substituents may be the same or different. In one embodiment, an optionally substituted group has one substituent. In another embodiment, an optionally substituted group has two substituents. In another embodiment, an optionally substituted group has three substituents. In another embodiment, an optionally substituted group has four substituents. In another embodiment, an optionally substituted group has five substituents. For example, an optionally substituted alkyl group may be a fully saturated alkyl chain (i.e., a pure hydrocarbon). Alternatively, the same optionally substituted alkyl group may have substituents other than hydrogen. For example, it can be bonded at any position on the chain to a halogen atom, a hydroxyl group, or any other substituent described herein. Thus, the term “optionally substituted” means that a given chemical structure portion may contain other functional groups, but does not necessarily have additional functional groups.
[0022] The term "alkyl," when used alone or as part of a larger group such as "arylalkyl" or "cycloalkyl," refers to a linear or branched hydrocarbon group having 1 to 10 carbon atoms, 1 to 8 carbon atoms, 1 to 6 carbon atoms, or 1 to 4 carbon atoms (unless otherwise specified), including, for example, methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, and n-hexyl. Alkyl groups may be unsubstituted or substituted with one or more suitable substituents.

The ring or ring system of a heterocycloalkyl group may be linked to other parts of a compound via carbon or nitrogen atoms, if present. A heterocycloalkyl group may have a total of 3 to 10 atoms, or 3 to 8 atoms, or 5 to 8 atoms in the ring system (unless otherwise specified). A heterocycloalkyl group may have one or more carbon-carbon double bonds or carbon-heteroatom double bonds in the cyclic group, provided that the cyclic group is not aromatized by their presence.
[0026] Examples of heterocycloalkyl groups include azetidinyl, azilidinyl, pyrrolidinyl, piperidinyl, piperazinyl, homopiperazinyl, morpholino, thiomorpholino, tetrahydrofuranil, tetrahydrothiofuranil, tetrahydropyranil, and pyranyl. Heterocycloalkyl groups may be unsubstituted or substituted with one or more suitable substituents.
[0027] In this specification, the term "halo" includes fluorine, chlorine, bromine, and iodine. In this specification, "alkoxy" refers to the alkyl groups linked via oxygen, examples of which include methoxy, ethoxy, isopropoxy, and tert-butoxy. Furthermore, alkoxy also refers to polyethers such as -O-(CH2)2-O-CH3. The alkoxy may be unsubstituted or substituted with one or more suitable substituents.
[0028] In this specification, the term "aryl" refers to an unsubstituted or substituted monocyclic or polycyclic aromatic group, including, for example, carbocyclic aromatic groups such as phenyl and naphthyl, and heteroaromatic groups such as pyridyl, furanyl, and thiophenyl. The term "aryl" also includes aromatic rings (such as phenyl and pyridyl rings) fused to nonaromatic carbocyclic or heterocyclic rings. The term "aryl" is interchangeable with "aryl ring," "aromatic group," and "aromatic ring." A heteroaryl group has 4 to 14 atoms in a heteroaromatic ring, of which 1 to 9 are independently selected from the group consisting of oxygen, sulfur, and nitrogen. A heteroaryl group has 1 to 3 heteroatoms in a 5 to 8-membered aromatic group. Aryl or heteroaryl can be monocyclic or bicyclic aromatic groups. Typical aryl and heteroaryl groups include, for example, phenyl, quinolineyl, indazoyl, indolyl, dihydrobenzodioxynyl, 3-chlorophenyl, 2,6-dibromophenyl, pyridyl, pyrimidinyl, 3-methylpyridyl, benzothienyl, 2,4,6-tribromophenyl, 4-ethylbenzothienyl, furanyl, 3,4-diethylfuranyl, naphthyl, 4,7-dichloronaphthyl, pyrrole, pyrazole, imidazole, and thiazole.

[0031] In this specification, “substituent” refers to a molecular portion covalently bonded to an atom within the molecule in question. For example, a cyclic substituent may be a halogen, alkyl group, haloalkyl group, or other group covalently bonded to an atom constituting the ring (preferably a carbon or nitrogen atom). Substituents of aromatic groups are generally covalently bonded to the ring carbon atom. The term “substitution” refers to replacing a hydrogen atom in a molecular structure with a substituent so that the valence of the specified atom is not exceeded and a chemically stable compound (i.e., a compound that can be isolated, characterized, and tested for biological activity) is obtained from the substitution.
[0032] As described above, certain groups are either unsubstituted or substituted with one or more suitable substituents (identical or different groups) other than hydrogen at one or more available positions, usually positions 1, 2, 3, 4, or 5. When a particular group is substituted, it is substituted with one, two, three, or four substituents independently selected. Suitable substituents include halo, alkyl, haloalkyl, aryl, hydroxy, alkoxy, hydroxyalkyl, and amino groups.

[0038] Prodrug derivatives of the compounds of the present invention can be prepared by methods known to those skilled in the art (for example, see Saulnier et al., Bioorg. Med. Chem.

[0039] The compounds of the present invention can be prepared as individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereomer compounds, and then separating the diastereomers to recover the optically pure enantiomers. The separation of the enantiomers can be performed using a covalent diastereomer derivative or a dissociable complex (e.g., a crystalline diastereomer salt) of the compound of the present invention. Each diastereomer has different physical properties (e.g., melting point, boiling point, solubility, reactivity, etc.), and these differences can be easily utilized for separation. The diastereomers can be separated by chromatography or by separation / resolving techniques based on differences in solubility. The optically pure enantiomers are then recovered together with the resolving agent by practical means that do not cause racemization. A detailed description of the techniques applicable to separating stereoisomers from a racemic mixture of the compound can be found in Jean Jacques, Andre Collet, and Samuel H. Wilen, "Enantiomers, Racemates and This is described in "Resolutions" (John Wiley And Sons, Inc., 1981), and the full disclosures of that document are incorporated herein by reference.

These methods generally involve administering an effective amount of the compounds described herein, their salts, diastereomers, enantiomers, racemates, hydrates, solvates, prodrugs, and / or compositions thereof, to a subject or contacting kinase-expressing cells in order to modulate or inhibit a signaling cascade. These methods are also used to modulate, and in particular inhibit, downstream processes or cellular responses induced by the activation of specific kinase signaling cascades. These methods can also be implemented in vitro or in vivo as therapeutic approaches toward the treatment or prevention of diseases characterized by, caused by, or associated with the activation of kinase-dependent signaling cascades.
[0057] In the therapeutic applications of compounds provided herein, including compounds of Formula 1, salts, diastereomers, enantiomers, racemates, hydrates, solvates, or prodrugs thereof, these compounds are administered alone or as part of a pharmaceutical composition in therapeutically effective amounts. Accordingly, this specification provides pharmaceutical compositions comprising at least one of the compounds described herein, including at least one compound of Formula 1, a pharmaceutically acceptable salt, diastereomer, enantiomer, racemate, hydrate, solvate, or prodrug thereof, and one or more pharmaceutically acceptable carriers, diluents, adjuvants, or excipients.
[0058] Furthermore, these compounds and compositions are administered alone or in combination with one or more additional therapeutic agents. Non-limiting examples of additional therapeutic agents include immune checkpoint inhibitors and immunogenic cell death (ICD) inducing chemotherapeutic agents. Non-limiting examples of immune checkpoint inhibitors include PD-1 inhibitors, PD-L1 inhibitors, and CTLA-4 inhibitors. Non-limiting examples of immunogenic cell death (ICD) inducing chemotherapeutic agents may include doxorubicin, idarubicin, mitoxantrone, tautomycin, calculin A, salbrinal, oxaliplatin, bleomycin, and cyclophosphamide. Methods of administration of these compounds and compositions include, but are not limited to, intravenous administration, inhalation, oral administration, rectal administration, parenteral administration, intravitreal administration, subcutaneous administration, intramuscular administration, intranasal administration, transdermal administration, topical administration, intraocular administration, oral administration, intratracheal administration, bronchial administration, sublingual administration, or optic nerve administration. The compounds provided herein are administered by known pharmaceutical formulations, including tablets, capsules, or elixirs for oral administration, suppositories for rectal administration, sterile solutions or suspensions for parenteral or intramuscular administration, and lotions, gels, ointments, or creams for topical administration. In some embodiments, these pharmaceutical compositions are formulated as tablets, pills, capsules, liquids, inhalants, nasal sprays, suppositories, solutions, gels, emulsions, ointments, eye drops, or ear drops.
[0059] The effective therapeutic dose varies depending particularly on the target disease, its severity, the patient's age and relative health status, the efficacy of the compound administered, the method of administration, and the desired treatment. The required dose also differs depending on the method of administration, the specific condition being treated, and the desired effect.
[0060] The compound of Formula 1 inhibits one or more protein kinases and is useful in treating protein kinase-mediated diseases and disorders such as cancer, autoimmune diseases, fibrotic diseases, cardiovascular diseases, and neurodegenerative diseases.
[0061] As used herein, the term “biological specimen” means a specimen taken outside of an animal body, and includes, but is not limited to, cell cultures or their extracts, biopsy material taken from an animal or its extracts, and blood, saliva, urine, feces, semen, tears, other bodily fluids or their extracts. Inhibition of kinase activity in biological specimens, particularly ROCK kinase activity, is useful for a variety of purposes known to those skilled in the art. Examples of such purposes include, but are not limited to, the preservation of biological specimens and biological assays.
[0062] In this specification, “ROCK-mediated disease” or “condition” means any disease or other adverse condition in which ROCK is known to be involved. ROCK is involved in various important physiological functions in the vascular system, including smooth muscle contraction, cell proliferation such as the proliferation of vascular smooth muscle cells, cell adhesion, and cell migration (Hu & Lee, Expert Opin. Ther. Targets, 9 (4):715-36, 2005; Shimokawa & Takeshita, Arterioscler). See Thromb. Vase. Biol. 25(9):1767-75, 2005). ROCK is also involved in inflammatory responses mediated by leukocyte migration, such as in autoimmune diseases and allergic reactions (see Wettschureck et al., J. Mol. Med. 80:629-38, 2002). Abnormal activation of the Rho / ROCK pathway has been observed in various central nervous system diseases (see Mueller et al., Nature Rev., 4:387-98, 2005). Furthermore, ROCK is involved in tumor cell migration and invasion (see Riento & Ridley, Nature Rev. 4:446-56, 2004) and osteoporosis (Ohnaka et al., Biochem. He has also been involved in Biophys., Res. Commun. 287(2):337-4, 2001).

[0074] [ka]
[0075] A bicyclic acid (2) was reacted with thionyl chloride or oxalyl chloride in dichloromethane in the presence of a catalytic amount of GMF to obtain acylchloride (3). The obtained acylchloride (3) was coupled with a bicyclic heteroaryl compound (4) by a Friedel-Crafts acylation reaction in an organic solvent (dichloromethane or dichloroethane) in the presence of a Lewis acid (aluminum chloride, titanium chloride, or stannous chloride) to obtain ketone (5). The obtained ketone (5) was reacted with an alkyl bromide, alkyl chloride, or alkyl epoxide in an organic solvent (dimethylformamide, acetone, dioxane, acetonitrile, dichloromethane, or dichloroethane) and reacted at room temperature (RT) to 150°C for 5 to 24 hours in the presence of an inorganic base (NaHCO3, Na2CO3, K2CO3, CS2CO3, K2HPO4, or K3PO4) to obtain an N-alkylated compound (6).
[0076] The N-alkylated compound (6) was also prepared by using a bicyclic heteroaryl compound (4) as a starting material, performing N-alkylation under the aforementioned reaction conditions to obtain (7), and then carrying out a Friedel-Crafts acylation reaction using acylchloride (3).
[0077] The N-alkylated compound (6) was reacted under Suzuki reaction conditions using a palladium catalyst (Pd(OAc)2, Pd2(dba)3, Pd(PPh3)4, or Pd(dppf)Cl2.DCM) to obtain compound (1) in the presence of an inorganic base (NaHCO3, Na2CO3, K2CO3, Cs2CO3, CsF, K2HPO4, or K3PO4) at room temperature (RT) to 150°C for 5 to 24 hours.
[0078] Alternatively, the N-alkylated compound (6) could also be prepared starting from a bicyclic compound, as shown in Method 2 below.
[0079] [ka]
[0080] Bicyclic heteroaryl compound (4) was reacted with N-iodosuccinimide (NIS) in an organic solvent (DMF, acetone, dioxane, acetonitrile, dichloromethane, or dichloroethane) at room temperature (RT) for 2 to 24 hours to obtain iodized bicyclic heteroaryl compound (8). Iodobicyclic heteroaryl compound (8) was reacted with alkyl bromide alkyl chloride or alkyl epoxide in an organic solvent (DMF, acetone, dioxane, acetonitrile, dichloromethane, or dichloroethane), and an inorganic base (NaHCO3, Na2CO3, K2CO3, Cs2CO3, K2HPO4, or K3PO4) was added, and the reaction was carried out for 5 to 24 hours under conditions of room temperature (RT) to -150°C. The N-alkylated compound (10) was alternatively prepared by N-alkylating the bicyclic heteroaryl compound (4) to obtain (9), and then iodizing (9) using N-iodosuccinimide (NCI) as described above. The bicyclic acid (2) was bonded with N-methoxymethanamine hydrochloride in an organic solvent (DMF, tetrahydrofuran, dichloromethane, or dichloroethane) using a coupling reagent (DCC, EDCI, HATU, HBTU, PyBop, or PyBrop) at room temperature for 2 to 24 hours to obtain winerebamide (11). This winerebamide (11) was converted to ketone (6) by reacting with the bicyclic heteroaryl iodide compound (10) in THF at a low temperature (-78 to 0°C) in the presence of a Grignard reagent.

[0083] The nuclear magnetic resonance (NMR) and mass spectrometry (MS) spectra obtained for the following examples and the compounds described herein were consistent with the spectra of the compounds according to the formulas described herein.
[0084] Liquid chromatography-mass spectrometry (LC-MS) method: 1. Samples were analyzed at room temperature at a flow rate of 1.5 mL / min using an Agilent Technologies 6120 MSD system equipped with a Zorbax Eclipse XDB-C18 (3.5 μm) reversed-phase column (4.6 × 50 mm). 2. The mobile phase was prepared by using solvent A (water / 0.1% formic acid) and solvent B (acetonitrile / 0.1% formic acid) for 5 minutes, and then diluting them by 95% / 5% to 0% / 100% (A / B). 3. The mass spectrum (m / z) was recorded using electro-spray ionization (ESI). 4. Ionization data was rounded to the nearest integer.
[0085] Proton NMR spectrum: Unless otherwise noted, all NMR spectra were measured using a Varian series Mercury 400 or 500 MHz NMR spectrometer. All observed protons are reported in ppm values at low magnetic fields from tetramethylsilane, using abbreviations conventionally used to denote major peaks, such as s (singlet), d (doublet), t (triplet), q (quartet), m (multiplet), and brs (broad singlet).
[0086] Example 1: Preparation of the compound [ka] Compound 1-1: (6-chlorochroman-3-yl)-[1-[2-(dimethylamino)ethyl]-6-(3-methoxy-1H-pyrazole-4-yl)pyrrolo[3,2-c]pyridine-3-yl]methanone (continues in step 5a.)
[0087] [ka]
[0088] Step 1: A mixture of 6-chlorochroman-3-carboxylic acid (6.0 g, 28.2 mmol), thionyl chloride (21.0 mL, 282.2 mmol), and DMF (0.1 mL, catalyst) was heated under reflux in toluene (60 mL) with stirring for 3 hours. The mixture was cooled to room temperature and concentrated to remove volatile organic solvents. The crude product was dissolved in acetonitrile (100 mL) and concentrated to obtain 1a as a light brown oily substance. 1a was used in the next step without purification.
[0089] Step 2: A mixture of 1a (5.4 g, 23 mmol) and 6-bromo-1H-pyrrolo[3,2-c]pyridine (3.7 g, 19 mmol) in dichloromethane (60 mL) was cooled in an ice bath, and aluminum chloride (9.4 g, 70 mmol) was added. At ℃ After stirring for 1 hour, saturated ammonium chloride aqueous solution (100 mL) was added at 0°C to stop the reaction and generate a solid precipitate. The mixture was then warmed to room temperature and stirred for a further 2 hours. The solid was collected by filtration and washed with methanol. The resulting solid was dried under high vacuum to obtain 1b as a white solid in 80% yield (7.4 g). LC / MS yielded 391.0 and 393.0 [M+H] + Detected.
[0090] Step 3: A mixture of 1b (800 mg, 2.1 mmol), potassium carbonate (1.76 g, 1.3 mmol, 770 μL), and 2-chloro-N,N-dimethylethanamine hydrochloride (690 mg, 6.4 mmol) was heated in DMF (20 mL) at 70°C for 16 hours. The mixture was poured into water (100 mL) and extracted with siRNA (100 mL). The organic layer was separated, washed with saturated brine (100 mL), dried over Na2SO4, filtered, and concentrated. The residue was purified by flash column chromatography on a silica gel column by gradient elution of 20–100% siRNA in hexane to obtain 1c as a white solid in 20% yield (202 mg). LC / MS analysis yielded 463.1 and 465.0 [M+H]+ It was detected.
[0091] Step 4: Intermediate 1c (202 mg, 43 μmol), a mixture of [3-methoxy-1-(p-toluylsulfonyl)pyrazole-4-yl]boronic acid (190 mg, 65 μmol), potassium carbonate (2 M aqueous solution, 54 μL), and tetrakis(triphenylphosphine)palladium (25.0 mg, 22 μmol) in 1,4-dioxane (10 mL), was degassed with argon gas for 5 minutes. The resulting mixture was heated to 70°C and shaken overnight. The mixture was cooled to room temperature, concentrated, poured into water (50 mL), and extracted twice with ethyl acetate (50 mL). The combined organic layer was dried over Na₂SO₄, filtered, and concentrated to obtain 1d. The residue was used in the next step without purification.
[0092] Step 5a for tosyl (Ts) protected pyrazole compound: A solution of 1d (crude, 230 mg) in THF (1 mL) was cooled on an ice bath and treated with 2N sodium hydroxide solution (2.0 mL). After stirring the solution at 0°C for 30 minutes, it was neutralized with 1N hydrochloric acid solution (4.0 mL) and diluted with  (30 mL) and saturated Na₂CO₃ solution (30 mL). The aqueous layer was separated and extracted with Â. The combined organic layers were dried over Na₂SO₄, filtered, treated with silica gel, and evaporated under reduced pressure.
