[0051] Any formula given herein, such as Formula (I) or (Ia), is intended to represent compounds having structures depicted by the structural formula as well as certain variations or forms. In particular, compounds of any formula given herein may have asymmetric centers and therefore exist in different enantiomeric or diastereomeric forms. All optical isomers and stereoisomers of the compounds of the general formula, and mixtures thereof in any ratio, are considered within the scope of the formula. Thus, any formula given herein is intended to represent a racemate, one or more enantiomeric forms, one or more diastereomeric forms, one or more atropisomeric forms, and mixtures thereof in any ratio. Where a compound of Table 1 is depicted with a particular stereochemical configuration, also provided herein is any alternative stereochemical configuration of the compound, as well as a mixture of stereoisomers of the compound in any ratio. For example, where a compound of Table 1 has a stereocenter that is in an “S” stereochemical configuration, also provided herein is enantiomer of the compound wherein that stereocenter is in an “R” stereochemical configuration. Likewise, when a compound of Table 1 has a stereocenter that is in an “R” configuration, also provided herein is enantiomer of the compound in an “S” stereochemical configuration. Also provided are mixtures of the compound with both the “S” and the “R” stereochemical configuration. Additionally, if a compound of Table 1 has two or more stereocenters, also provided are any enantiomer or diastereomer of the compound. For example, if a compound of Table 1 contains a first stereocenter and a second stereocenter with “R” and “R” stereochemical configurations, respectively, also provided are stereoisomers of the compound having first and second stereocenters with “S” and “S” stereochemical configurations, respectively, “S” and “R” stereochemical configurations, respectively, and “R” and “S” stereochemical configurations, respectively. If a compound of Table 1 contains a first stereocenter and a second stereocenter with “S” and “S” stereochemical configurations, respectively, also provided are stereoisomers of the compound having first and second stereocenters with “R” and “R” stereochemical configurations, respectively, “S” and “R” stereochemical configurations, respectively, and “R” and “S” stereochemical configurations, respectively. If a compound of Table 1 contains a first stereocenter and a second stereocenter with “S” and “R” stereochemical configurations, respectively, also provided are stereoisomers of the compound having first and second stereocenters with “R” and “S” stereochemical configurations, respectively, “R” and “R” stereochemical configurations, respectively, and “S” and “S” stereochemical configurations, respectively. Similarly, if a compound of Table 1 contains a first stereocenter and a second stereocenter with “R” and “S” stereochemical configurations, respectively, also provided are stereoisomers of the compound having first and second stereocenters with “S” and “R” stereochemical configurations, respectively, “R” and “R” stereochemical configurations, respectively, and “S” and “S” stereochemical configurations, respectively. Furthermore, certain structures may exist as geometric isomers (i.e., cis and trans isomers), as tautomers, or as atropisomers. Additionally, any formula given herein is intended to refer also to any one of hydrates, solvates, and amorphous and polymorphic forms of such compounds, and mixtures thereof, even if such forms are not listed explicitly. In some embodiments, the solvent is water and the solvates are hydrates.

[0052] The compounds of the present disclosure can also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. For example, the present disclosure also embraces isotopically-labeled variants of the present disclosure which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having the atomic mass or mass number different from the predominant atomic mass or mass number usually found in nature for the atom. All isotopes of any particular atom or element as specified are contemplated within the scope of the compounds of the present disclosure and include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, sulfur, fluorine, chlorine and iodine, such as .sup.2H (“D”), .sup.3H, .sup.11C, .sup.13C, .sup.14C, .sup.13N, .sup.15N, .sup.15O, .sup.17O, .sup.18O, .sup.32P, .sup.33P, .sup.35S, .sup.18F, .sup.36Cl, .sup.123I and .sup.125I.

[0053] In some variations, any of the compounds described herein, such as a compound of Formula (I) or (Ia), or any variation thereof, or a compound of Table 1 may be deuterated (e.g., a hydrogen atom is replaced by a deuterium atom). In some of these variations, the compound is deuterated at a single site. In other variations, the compound is deuterated at multiple sites. Deuterated compounds can be prepared from deuterated starting materials in a manner similar to the preparation of the corresponding non-deuterated compounds. Hydrogen atoms may also be replaced with deuterium atoms using other method known in the art. Indication of an atom indicates isotopic variants of said atom, for instance, an explicit or implicit hydrogen includes deuterium at that position.

Preparation of Ethyl 5-(N-((3R,4S)-6-chloro-7-fluoro-4-hydroxychroman-3-yl)sulfamoyl)-2-methyl-1H-pyrrole-3-carboxylate (Intermediate 24.1)

[0274] Ethyl ((3R,4S)-6-chloro-7-fluoro-4-hydroxychroman-3-yl)carbamate (157 mg, 0.54 mmol) was dissolved in ethanol (5.0 mL), and 50% aqueous NaOH (1 ml) was added. The resulting mixture was stirred at 100° C. for 16 h. It was cooled to room temperature, and ethanol removed under reduced pressure. The resulting solution was diluted with water (10 mL) and extracted with ethyl acetate (3×25 mL). The organic extracts were combined, dried over sodium sulfate and concentrated to a glassy solid. The solid was dissolved in dichloromethane (2.0 mL) and diisopropylethylamine (0.283 ml, 1.63 mmol) was added. Ethyl 5-(chlorosulfonyl)-2-methyl-1H-pyrrole-3-carboxylate (0.150 g, 0.60 mmol) was added, and the resulting mixture was stirred and room temperature for 15 min. The reaction was diluted with additional dichloromethane (20 mL), washed with 0.1 M HCl (15 mL), brine and dried over sodium sulfate. Concentration under reduced pressure provided a tan solid which was purified with silica gel using 30% ethyl acetate/hexanes, followed by reverse phase HPLC using a 40 min gradient from 10-100% acetonitrile/water with 0.1% formic acid (Phenomenex Gemini 5 micron C18 column, 150×21 mm, Axia Pack) to give 0.147 g (63%) of ethyl 5-(N-((3R,4S)-6-chloro-7-fluoro-4-hydroxychroman-3-yl)sulfamoyl)-2-methyl-1H-pyrrole-3-carboxylate as a white solid. .sup.1H NMR (400 MHz, Methanol-d.sub.4) δ 7.32 (d, J=8.3 Hz, 1H), 7.03 (s, 1H), 6.69 (d, J=10.4 Hz, 1H), 4.46 (d, J=3.7 Hz, 1H), 4.26 (q, J=7.1 Hz, 2H), 4.04 (t, J=10.4 Hz, 1H), 3.94 (dd, J=10.4, 3.7 Hz, 1H), 3.70 (dt, J=10.4, 3.7 Hz, 1H), 2.52 (s, 3H), 1.34 (t, J=7.1 Hz, 3H).

Preparation of N-((3R,4S)-6-chloro-7-fluoro-4-hydroxychroman-3-yl)-4-(3-cyano-3-methylazetidine-1-carbonyl)-5-methyl-1H-pyrrole-2-sulfonamide

[0285] 2.0 M NaOH (2.0 mL) was added to ethyl 5-(N-((3R,4S)-6-chloro-7-fluoro-4-hydroxychroman-3-yl)sulfamoyl)-2-methyl-1H-pyrrole-3-carboxylate (45 mg, 0.10 mmol, 1.0 equiv) in ethanol (2.0 mL) before being heated to 100° C. After 5 h, the reaction was returned to rt and ethanol removed by rotary evaporation. The pH was adjusted to 3 using 1.0 M HCl and extracted with ethyl acetate (3×10 mL). The organic extracts were combined, dried over sodium sulfate, filtered, and concentrated under reduced pressure. The remaining solid was dissolved in N-methylpyrrolidone (1.5 mL) before 3-methylazetidine-3-carbonitrile hydrochloride (27 mg, 0.20 mmol), HBTU (76 mg, 0.20 mmol), HOBt (27 mg, 0.20 mmol) and diisopropylethylamine (0.087 mL, 0.50 mmol) were added and the resulting solution was stirred at room temperature for 30 min. The reaction mixture was purified by reverse phase HPLC (10->100% MeCN/water with 0.1% formic acid, Phenomenex Gemini 5 micron Cis column, 150×21 mm, Axia Pack) to give the product as a white solid (31 mg, 64%). .sup.1H NMR (400 MHz, Methanol-d.sub.4) δ 7.32 (d, J=8.3 Hz, 1H), 6.86 (s, 1H), 6.69 (d, J=10.3, 1H), 4.69 (s, 1H), 4.52-4.19 (m, 3H), 4.04 (td, J=10.4, 1.1 Hz, 2H), 3.93 (ddd, J=10.6, 3.9, 1.1 Hz, 1H), 3.72 (ddd, J=10.3, 4.4, 3.4 Hz, 1H), 2.49 (s, 3H), 1.69 (s, 3H).

BIOLOGICAL EXAMPLES

Example B-1. In Vitro Model of Dose-Dependent Myofibril ATPase Modulation

[0304] Dose responses were measured using a calcium-buffered, pyruvate kinase and lactate dehydrogenase-coupled ATPase assay containing the following reagents (concentrations expressed are final assay concentrations): Potassium PIPES (12 mM), MgCl.sub.2 (2 mM), ATP (1 mM), DTT (1 mM), BSA (0.1 mg/ml), NADH (0.5 mM), PEP (1.5 mM), pyruvate kinase (4 U/ml), lactate dehydrogenase (8 U/ml), and antifoam (90 ppm). The pH was adjusted to 6.80 at 22° C. by addition of potassium hydroxide. Calcium levels were controlled by a buffering system containing 0.6 mM EGTA and varying concentrations of calcium, to achieve a free calcium concentration of 1×10.sup.−4 M to 1×10.sup.−8 M.

[0305] Bovine cardiac myofibrils were obtained by homogenizing the appropriate tissue in the presence of detergent. Such treatment removes membranes and majority of soluble cytoplasmic proteins but leaves intact cardiac sarcomeric acto-myosin apparatus. Concentrations of myofibrils were adjusted to achieve the necessary rate of ATP hydrolysis (typically 0.25-1.0 mg/ml).

[0306] Chemical entity dose responses were measured at the calcium concentration corresponding to 25% of maximal ATPase activity (pCa.sub.25), so a preliminary experiment was performed to test the response of the ATPase activity to free calcium concentrations in the range of 1×10.sup.−4 M to 1×10.sup.−8 M. Subsequently, the assay mixture was adjusted to the pCa.sub.25. Assays were performed by first preparing a dilution series of test chemical entity, each with an assay mixture containing potassium Pipes, MgCl.sub.2, BSA, DTT, pyruvate kinase, lactate dehydrogenase, myofibrils, antifoam, EGTA, CaCl.sub.2), and water. The assay was started by adding an equal volume of solution containing potassium Pipes, MgCl.sub.2, BSA, DTT, ATP, NADH, PEP, antifoam, and water. ATP hydrolysis was monitored by absorbance at 340 nm. The resulting dose response curve was fit by the 4 parameter equation y=Bottom+((Top−Bottom)/(1+((EC50/X){circumflex over ( )}Hill))). The AC1.4 is defined as the concentration at which ATPase activity was 1.4-fold higher than the bottom of the dose curve. AC1.4 values reported in the table below are mean values based on a minimum of two independent tests. For compounds for which two independent tests were performed, the individual values were within two-fold of each other. For compounds for which more than two independent tests were performed, the typical error is mean+/−20-30%.
