Design and synthesis of sulfonamidophenylethylureas as novel cardiac myosin activator

Design and synthesis of sulfonamidophenylethylureas as novel cardiac myosin activator To optimize the lead urea scaffold 1 and 2 as selective cardiac myosin ATPase activator, a series of urea derivatives have been synthesized to explore its structure activity relationship. Among them N,N-dimethyl-4-(2-(3-(3-phenylpropyl)ureido)ethyl)benzenesulfonamide (13, CMA = 91.6%, FS = 17.62%; EF = 11.55%), N,N-dimethyl-4-(2-(1-methyl-3-(3-phenylpropyl)ureido)ethyl)benzene sulfonamide (40, CMA = 52.3%, FS = 38.96%; EF = 24.19%) and N,N-dimethyl-4-(2-(3-methyl-3-(3-phenylpropyl)ureido)ethyl)benzenesulfonamide (41, CMA = 47.6%, FS = 23.19%; EF = 15.47%) proved to be efficient to activate the cardiac myosin in vitro and in vivo. Further the % change in ventricular cell contractility at 5 μM of 13 (47.9 ± 3.2), 40 (45.5 ± 2.4) and 41 (63.5 ± 2.2) showed positive inotropic effect in isolated rat ventricular myocytes.

Abstract

To optimize the lead urea scaffold 1 and 2 as selective cardiac myosin ATPase activator, a series of urea derivatives have been synthesized to explore its structure activity relationship. Among them N,N-dimethyl-4-(2-(3-(3-phenylpropyl)ureido)ethyl)benzenesulfonamide (13, CMA = 91.6%, FS = 17.62%; EF = 11.55%), N,N-dimethyl-4-(2-(1-methyl-3-(3-phenylpropyl)ureido)ethyl)benzene sulfonamide (40, CMA = 52.3%, FS = 38.96%; EF = 24.19%) and N,N-dimethyl-4-(2-(3-methyl-3-(3-phenylpropyl)ureido)ethyl)benzenesulfonamide (41, CMA = 47.6%, FS = 23.19%; EF = 15.47%) proved to be efficient to activate the cardiac myosin in vitro and in vivo. Further the % change in ventricular cell contractility at 5 μM of 13 (47.9 ± 3.2), 40 (45.5 ± 2.4) and 41 (63.5 ± 2.2) showed positive inotropic effect in isolated rat ventricular myocytes. The potent compounds 13, 40, 41 were highly selective for cardiac myosin over skeletal and smooth muscle myosin, thus proving them these new urea derivatives is a novel scaffold for discovery of cardiac myosin activators for the treatment of systolic heart failure.
