Abstract
Description
Technical Field
[0001] Cross - Reference to Related Applications This application claims priority to U.S. Provisional Patent Application No. 62 / 619,643, filed on January 19, 2018, entitled "CARDIAC SARCOMERE INHIBITORS" and U.S. Provisional Patent Application No. 62 / 745,724, filed on October 15, 2018, entitled "CARDIAC SARCOMERE INHIBITORS", the entire contents of which are hereby incorporated by reference for all purposes.
[0002] Heterocyclic compounds, pharmaceutical compositions containing such compounds, and methods of treating various heart diseases and conditions with such compounds are provided herein.
Background Art
[0003] This disclosure relates to certain chemical entities that selectively modulate the sarcomere, specifically, certain chemical entities, pharmaceutical compositions, and methods for treating various heart diseases and conditions.
[0004] The sarcomere is composed of a network of contractile and structural proteins that regulate myocardial function. The components of the sarcomere are targeted for the treatment of various heart diseases and conditions, for example, by increasing contractility or promoting complete relaxation to modulate contractile and diastolic functions respectively. The force and velocity of myocardial contraction are major determinants of organ function and are modulated by the periodic interaction of actin and myosin. The regulation of actin - myosin binding is determined by the network of thin - filament regulatory proteins and the intracellular Ca 2+ level. Troponin complex and tropomyosin are thin - filament proteins that govern the availability of the actin - binding site, and essential and regulatory light chains, as well as myosin - binding protein C, modulate the position and mechanical properties of myosin.
[0005] Abnormalities in the sarcomere have been identified as a cause driving various heart diseases and conditions such as hypertrophic cardiomyopathy (HCM) and heart failure with preserved ejection fraction (HFpEF). Mutations in sarcomeric proteins cause disease by bringing about either "high" or "low" contractility in the myocardium. By using sarcomere modulators, contractility can be rebalanced, and the disease process can be halted or reversed. SUMMARY OF THE INVENTION MEANS FOR SOLVING THE PROBLEM
[0006] Current agents targeting the sarcomere, such as inotropes (drugs that increase the contractile ability of the heart), lack selectivity for heart tissue, thereby resulting in recognized adverse effects that limit the use of inotropes. These adverse effects include cell damage caused by increased energy consumption rate, aversion to relaxation abnormalities, and potential arrhythmogenic side effects that may result from increased cytosolic Ca++ and cyclic AMP concentrations in the myocardium stimulated by the inotropic action. Considering the limitations of current agents, new approaches are needed to improve cardiac function in HCM and HFpEF.
[0007] There remains a strong need for agents that explore new mechanisms of action and can have better outcomes with respect to symptom relief, safety, and patient mortality both in the short - term and long - term. New agents with an improved therapeutic index compared to current agents will provide a means to achieve these clinical outcomes. The selectivity of agents targeting the sarcomere (e.g., by targeting cardiac myosin) has been identified as an important means to achieve this improved therapeutic index. The present disclosure provides such agents (particularly sarcomere inhibitors), and methods of using them. These agents are selective allosteric inhibitors of cardiac myosin that have little or no effect on smooth muscle myosin. The benefits of these compounds include a broader therapeutic index, less impact on heart relaxation, better pharmacokinetics, and better safety.
[0008] The present disclosure provides chemical entities, pharmaceutical compositions and methods for the treatment of heart failure, including HCM and HFpEF. The compositions are inhibitors of the myocardial segment, for example, inhibitors of myocardial myosin.

DETAILED DESCRIPTION OF THE INVENTION
[0032] Definition As used herein, the following words and phrases generally are intended to have the meanings as set forth below, unless the context in which they are used indicates otherwise.

Similarly, the term "salt" includes solvates of the salts of the compounds.
[0034] "Alkyl" includes straight-chain and branched carbon chains having the indicated number of carbon atoms, for example, from 1 to 20 carbon atoms, or from 1 to 8 carbon atoms, or from 1 to 6 carbon atoms. For example, C 1~6 Alkyl includes both straight-chain and branched-chain alkyls of 1 to 6 carbon atoms. When naming an alkyl residue having a specific number of carbons, all branched and straight-chain versions having that number of carbons are intended to be included. Thus, for example, "propyl" includes n-propyl and isopropyl, and "butyl" includes n-butyl, sec-butyl, isobutyl, and t-butyl. Examples of alkyl groups include, but are not limited to, methyl, ethyl, propyl, isopropyl, n-butyl, sec-butyl, tert-butyl, pentyl, 2-pentyl, 3-pentyl, isopentyl, neopentyl, hexyl, 2-hexyl, 3-hexyl, and 3-methylpentyl.
[0035] When a range of values is given (e.g., C 1~6 alkyl), each value within the range, and all intervening ranges, are included. For example, "C 1~6 alkyl" includes C1, C2, C3, C4, C5, C6, C 1~6 , C 2~6 , C 3~6 , C 4~6 , C 5~6 , C 1~5 , C 2~5 , C 3~5 , C 4~5 , C 1~4 , C 2~4 , C 3~4 , C 1~3 , C 2~3 and C 1~2 alkyl.
[0036] "Alkenyl" refers to a branched or straight-chain unsaturated alkyl group having the indicated number of carbon atoms (e.g., 2 to 8 or 2 to 6 carbon atoms) and at least one carbon-carbon double bond. The group can be in either the cis or trans configuration (Z or E configuration) with respect to the double bond. Alkenyl groups include, but are not limited to, ethenyl, propenyl (e.g., prop-1-en-1-yl, prop-1-en-2-yl, prop-2-en-1-yl (allyl), prop-2-en-2-yl) and butenyl (e.g., but-1-en-1-yl, but-1-en-2-yl, 2-methyl -prop-1-en-1-yl, but-2-en-1-yl, but-2-en-1-yl, but-2-en-2-yl, buta-1,3-dien-1-yl, buta-1,3-dien-2-yl).
[0037] "Alkynyl" refers to a branched or straight-chain unsaturated alkyl group having the indicated number of carbon atoms (e.g., 2 to 8 or 2 to 6 carbon atoms) and at least one carbon-carbon triple bond. Alkynyl groups include, but are not limited to, ethynyl, propynyl (e.g., prop-1-yn-1-yl, prop-2-yn-1-yl) and butynyl (e.g., but-1-yn-1-yl, but-1-yn-3-yl, but-3-yn-1-yl).
[0038] "Cycloalkyl" refers to a non-aromatic, fully saturated carbocyclic ring having the indicated number of carbon atoms, e.g., 3 to 10 or 3 to 8 or 3 to 6 ring carbon atoms. The cycloalkyl group may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). Examples of cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl, as well as bridged and cage-type ring groups (e.g., norbornane, bicyclo[2.2.2]octane). Further, one ring of a polycyclic cycloalkyl group may be aromatic, provided that the polycyclic cycloalkyl group is attached to the parent structure via a non-aromatic carbon. For example, the 1,2,3,4-tetrahydronaphthalen-1-yl group (the moiety is attached to the parent structure via a non-aromatic carbon atom) is a cycloalkyl group, while 1,2,3,4-tetrahydronaphthalen-5-yl (the moiety is attached to the parent structure via an aromatic carbon atom) is not considered a cycloalkyl group. Examples of polycyclic cycloalkyl groups consisting of cycloalkyl groups fused to an aromatic ring are described below.
[0039] "Cycloalkenyl" refers to a non-aromatic carbocyclic ring containing the indicated number of carbon atoms (e.g., 3 to 10, or 3 to 8, or 3 to 6 ring carbon atoms) and at least one carbon-carbon double bond. The cycloalkenyl group may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). Examples of cycloalkenyl groups include cyclopropenyl, cyclobutenyl, cyclopentenyl, cyclopentadienyl and cyclohexenyl, as well as bridged and basket-type ring groups (e.g., bicyclo[2.2.2]octene). Further, one ring of a polycyclic cycloalkenyl group may be aromatic, provided that the polycyclic cycloalkenyl group is attached to the parent structure through a non-aromatic carbon atom. For example, inden-1-yl (the moiety is attached to the parent structure through a non-aromatic carbon atom) is considered a cycloalkenyl group, while inden-4-yl (the moiety is attached to the parent structure through an aromatic carbon atom) is not considered a cycloalkenyl group. Examples of polycyclic cycloalkenyl groups consisting of cycloalkenyl groups fused to an aromatic ring are described below.
[0040] "Aryl" refers to an aromatic carbocyclic ring having the indicated number of carbon atoms, e.g., 6 to 12 or 6 to 10 carbon atoms. The aryl group may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). In some examples, both rings of the polycyclic aryl group are aromatic (e.g., naphthyl). In other examples, the polycyclic aryl group may include a non-aromatic ring fused to an aromatic ring, provided that the polycyclic aryl group is attached to the parent structure through an atom in the aromatic ring. Thus, the 1,2,3,4-tetrahydronaphthalen-5-yl group (the moiety is attached to the parent structure through an aromatic carbon atom) is considered an aryl group, while 1,2,3,4-tetrahydronaphthalen-1-yl (the moiety is attached to the parent structure through a non-aromatic carbon atom) ) is not considered an aryl group. However, the term "aryl" does not include, and is not overlapping with, "heteroaryl" as defined herein regardless of the point of attachment (e.g., both quinolin-5-yl and quinolin-2-yl are heteroaryl groups). In some examples, aryl is phenyl or naphthyl. In certain cases, aryl is phenyl. Additional examples of aryl groups containing an aromatic carbocyclic ring fused to a non-aromatic ring are described below.
[0041] "Heteroaryl" refers to an aromatic ring (e.g., 5- to 12-membered or 5- to 10-membered heteroaryl) containing a display number of atoms composed of one or more heteroatoms selected from N, O, and S (e.g., 1, 2, 3, or 4 heteroatoms), with the remaining ring atoms being carbon. The heteroaryl group does not contain adjacent S and O atoms. In some embodiments, the total number of S and O atoms in the heteroaryl group is 2 or less.

[0044] In other examples, the polycyclic heteroaryl group may include a non-aromatic ring (e.g., cycloalkyl, cycloalkenyl, heterocycloalkyl, heterocycloalkenyl) fused to the heteroaryl ring, provided that the polycyclic heteroaryl group is attached to the parent structure through an atom in the aromatic ring. For example, the 4,5,6,7-tetrahydrobenzo[d]thiazol-2-yl group (the moiety is attached to the parent structure through an aromatic carbon atom) is regarded as a heteroaryl group, while 4,5,6,7-tetrahydrobenzo[d]thiazol-5-yl (the moiety is attached to the parent structure through a non-aromatic carbon atom) is not regarded as a heteroaryl group. Examples of polycyclic heteroaryl groups consisting of a heteroaryl ring fused to a non-aromatic ring are described below.
[0045] "Heterocycloalkyl" refers to a non-aromatic, fully saturated ring (e.g., 3- to 10-membered or 3- to 7-membered heterocycloalkyl) having a indicated number of atoms composed of one or more heteroatoms selected from N, O, and S (e.g., one, two, three, or four heteroatoms), with the remaining ring atoms being carbon. The heterocycloalkyl group may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). Examples of heterocycloalkyl groups include oxiranyl, aziridinyl, azetidinyl, pyrrolidinyl, imidazolidinyl, pyrazolidinyl, piperidinyl, piperazinyl, morpholinyl, and thiomorpholinyl. Examples include thiomorpholine S-oxide and thiomorpholine S,S-dioxide. Further, one ring of a polycyclic heterocycloalkyl group may be aromatic (e.g., aryl or heteroaryl), provided that the polycyclic heterocycloalkyl group is attached to the parent structure via a non-aromatic carbon or nitrogen atom. For example, the 1,2,3,4-tetrahydroquinolin-1-yl group (the moiety is attached to the parent structure via a non-aromatic nitrogen atom) is considered a heterocycloalkyl group, while the 1,2,3,4-tetrahydroquinolin-8-yl group (the moiety is attached to the parent structure via an aromatic carbon atom) is not considered a heterocycloalkyl group. Examples of polycyclic heterocycloalkyl groups consisting of heterocycloalkyl groups fused to an aromatic ring are described below.
[0046] "Heterocycloalkenyl" has a number of atoms composed of one or more heteroatoms selected from N, O, and S (e.g., 1, 2, 3, or 4 heteroatoms), with the remaining ring atoms being carbon, and at least one double bond being derived from the removal of one molecule of hydrogen from adjacent carbon atoms, adjacent nitrogen atoms, or adjacent carbon and nitrogen atoms of the corresponding heterocycloalkyl, and represents a non-aromatic ring (e.g., 3- to 10-membered or 3- to 7-membered heterocycloalkyl). The heterocycloalkenyl group may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). Examples of heterocycloalkenyl groups include dihydrofuranyl (e.g., 2,3-dihydrofuranyl, 2,5-dihydrofuranyl), dihydrothiophenyl (e.g., 2,3-dihydrothiophenyl, 2,5-dihydrothiophenyl), dihydropyrrolyl (e.g., 2,3-dihydro-1H-pyrrolyl, 2,5-dihydro- 1H-pyrrolyl), dihydroimidazolyl (e.g., 2,3-dihydro-1H-imidazolyl, 4,5-dihydro-1H-imidazolyl), pyranyl, dihydropyranyl (e.g., 3,4-dihydro-2H-pyranyl, 3,6-dihydro-2H-pyranyl), tetrahydropyridinyl (e.g., 1,2,3,4-tetrahydropyridinyl, 1,2,3,6-tetrahydropyridinyl), and dihydropyridine (e.g., 1,2-dihydropyridine, 1,4-dihydropyridine). Further, one ring of a polycyclic heterocycloalkenyl group may be aromatic (e.g., aryl or heteroaryl), provided that the polycyclic heterocycloalkenyl group is attached to the parent structure via a non-aromatic carbon or nitrogen atom. For example, the 1,2-dihydroquinolin-1-yl group (the moiety is attached to the parent structure via a non-aromatic nitrogen atom) is regarded as a heterocycloalkenyl group, while the 1,2-dihydroquinolin-8-yl group (the moiety is attached to the parent structure via an aromatic carbon atom) is not regarded as a heterocycloalkenyl group. Examples of polycyclic heterocycloalkenyl groups composed of heterocycloalkenyl groups fused to an aromatic ring are described below.
[0047] Examples of polycyclic rings composed of aromatic rings (e.g., aryl or heteroaryl) fused to non-aromatic rings (e.g., cycloalkyl, cycloalkenyl, heterocycloalkyl, heterocycloalkenyl) include indenyl, 2,3-dihydro-1H-indenyl, 1,2,3,4-tetrahydronaphthalenyl, benzo[1,3]dioxolyl, tetrahydroquinolinyl, 2,3-dihydrobenzo[1,4]dioxinyl, indolinyl, isoindolinyl, 2,3-dihydro-1H-indazolyl, 2,3-dihydro-1H-benzo[d]imidazolyl, 2,3-dihydrobenzofuranyl, 1,3-dihydroisobenzofuranyl, 1,3-dihydrobenzo[c]isoxazolyl, 2,3-dihydrobenzo[d]isoxazolyl, 2,3-dihydrobenzo[d]oxazolyl, 2,3-dihydrobenzo[b]thiophenyl, 1,3-dihydrobenzo[c]thiophenyl, 1,3-dihydrobenzo[c]isothiazolyl, 2,3-dihydrobenzo[d]isothiazolyl, 2,3-dihydrobenzo[d]thiazolyl, 5,6-dihydro-4H-cyclopenta[d]thiazolyl, 4,5,6,7-tetrahydrobenzo[d]thiazolyl, 5,6-dihydro-4H-pyrrolo[3,4-d]thiazolyl, 4,5,6,7-tetrahydrothiazolo[5,4-c]pyridinyl, indolin-2-one, indolin-3-one, isoindolin-1-one, 1,2-dihydroindazol-3-one, 1H-benzo[d]imidazol-2(3H)-one, benzofuran-2(3H)-one, benzofuran-3(2H)-one, isobenzofuran-1(3H)-one, benzo[c]isoxazol-3(1H)-one, benzo[d]isoxazol-3(2H)-one, benzo[d]oxazol-2(3H)-one, benzo[b]thiophen-2(3H)-one, benzo[b]thiophen-3(2H)-one, benzo[c]thiophen-1(3H)-one, benzo[c]isothiazol-3(1H)-one, benzo[d]isothiazol-3(2H)-one, benzo[d]thiazol-2(3H)-one, 4,5-dihydropyrrolo[3,4-d]thiazol-6-one, 1,2-dihydropyrazolo[3,4-d]thiazol-3-one, quinolin-4(3H)-one, quinazolin-4(3H)-one, quinazolin-2,4(1H,3H)-dione, quinoxalin-2(1H)-one, quinoxalin-2,3(1H,4H)-dione, cinnolin-4(3H)-one, pyridin-2(1H)-one, pyrimidin-2(1H)-one, pyrimidin-4(3H)-one, pyridazin-3(2H)-one, 1H-pyrrolo[3,2-b]pyridin-2(3H)-one, 1H-pyrrolo[3,2-c]pyridin-2(3H)-one, 1H-pyrrolo[2,3-c]pyridin-2(3H)-one, 1H-pyrrolo[2,3-b]pyridin-2(3H)-one, 1,2-dihydropyrazolo[3,4-d]thiazol-3-one and 4,5-dihydropyrrolo[3,4-d]thiazol-6-one are included. As discussed herein, whether each ring is considered to be an aryl, heteroaryl, cycloalkyl, cycloalkenyl, heterocycloalkyl or heterocycloalkenyl group depends on the atom to which the moiety is attached to the parent structure, which is determined.

As used herein, "modulation" refers to a change in activity as a direct or indirect response to the presence of a chemical entity described herein, compared to the activity in the absence of the chemical entity. The change can be an increase or a decrease in activity and can be due to a direct interaction of the chemical entity with its target or due to an interaction of the chemical entity with one or more other factors that later affect the activity of the target. For example, the presence of a chemical entity can increase or decrease target activity (directly or indirectly) by, for example, directly binding to the target, increasing or decreasing target activity (directly or indirectly) of another factor, or increasing or decreasing (directly or indirectly) the amount of target present in a cell or organism.
[0060] The term "therapeutically effective amount" or "effective amount" refers to the amount of a compound disclosed and / or described herein that is sufficient to affect a treatment as defined herein when administered to a patient in need of such treatment. The therapeutically effective amount of a compound may be an amount sufficient to treat a disease responsive to modulation of a myocardial segment. The therapeutically effective amount will vary depending, for example, on the subject being treated and the disease state, the body weight and age of the subject, the severity of the disease state, the particular compound, the dosing regimen followed, the timing of administration, the mode of administration, all of which can be readily determined by one of ordinary skill in the art. The therapeutically effective amount may be determined experimentally, for example, by assaying the blood concentration of the chemical entity or theoretically by calculating the bioavailability.
[0061] "Treatment" (and related terms such as "treat", "treated", "treating") means preventing a disease or disorder (i.e., not causing the clinical symptoms of the disease or disorder) including one or more of inhibiting a disease or disorder, slowing or arresting the onset of clinical symptoms of a disease or disorder, and / or alleviating a disease or disorder (i.e., causing alleviation or regression from clinical symptoms). The terms encompass situations where the disease or disorder has already been experienced by the patient and situations where the disease or disorder has not currently been experienced but is expected to occur. The terms encompass both complete or partial reduction or prevention of a condition or disorder and complete or partial reduction of clinical symptoms of a disease or disorder.

In some embodiments, the one or more therapies include treatments that improve cardiac function by stimulating cardiac contractility (e.g., positive inotropes such as the β-adrenergic agonist dobutamine or the phosphodiesterase inhibitor milrinone). In other embodiments, the one or more therapies include treatments that reduce cardiac preload (e.g., diuretics such as furosemide) or cardiac afterload (any class of vasodilators including, but not limited to, calcium channel blockers, phosphodiesterase inhibitors, endothelin receptor antagonists, renin inhibitors or smooth muscle myosin modulators).
[0180] The compounds and compositions described and / or disclosed herein may be combined with one or more other therapies for treating HCM or HFpEF. In some embodiments, the compounds and / or compositions may be combined with verapamil and / or disopyramide, which are β-blockers.
[0181] General synthetic method The compounds of formulas (I), (Ia), (Ib), (Ic), (Id), (Ie), (If), (Ig), (Ih), (Ii), (Ij) and (Ik) are described herein by reference to exemplary synthetic schemes for their general preparation and subsequent specific examples thereof. One of ordinary skill in the art will recognize that, in order to obtain the various compounds herein, the starting materials can be suitably selected such that the ultimately desired substituents are carried through the reaction scheme, optionally with protection or without protection, as appropriate, to obtain the desired product. Alternatively, it may be necessary or desirable to use suitable groups that are carried through the reaction scheme and optionally replaced by the ultimately desired substituents. Further, one of ordinary skill in the art will recognize that protecting groups can be used to protect certain functional groups (amino, carboxy or side chain groups) from the reaction conditions and that such groups are removed under standard conditions when appropriate. Unless otherwise specified, for formulas (I), (Ia), (Ib), (Ic), (Id), (Ie), (If), (Ig), (Ih), (Ii), (Ij) and (Ik), the variables are as defined above.
[0182] If it is desired to obtain a particular enantiomer of a compound, this can be accomplished from the corresponding mixture of enantiomers using any suitable conventional procedure for separating or resolving enantiomers. Thus, for example, diastereomeric derivatives can be produced by reaction of a mixture of enantiomers (e.g., a racemate and a suitable chiral compound). The diastereomers can then be separated by any convenient means, e.g., by crystallization, and the desired enantiomer recovered. In another resolution process, a racemate can be separated using chiral high performance liquid chromatography. Alternatively, if desired, a particular enantiomer can be obtained by using a suitable chiral intermediate in one of the described processes.
[0183] If it is desired to obtain a specific isomer of the compound or otherwise purify the reaction product, chromatography, recrystallization and other conventional separation procedures may also be used with the intermediate or the final product.
[0184] The general methods for preparing the compounds described herein are shown in the methods exemplified below. The variable groups in the schemes provided herein are defined with respect to formula (I), (Ia), (Ib), (Ic), (Id), (Ie), (If), (Ig), (Ih), (Ii), (Ij) and (Ik) or any variant thereof. Other compounds described herein can be prepared by similar methods.
