A series of flexible urea derivatives have been synthesized and demonstrated as selective cardiac myosin ATPase activator. Among them 1-phenethyl-3-(3-phenylpropyl)urea (1, cardiac myosin ATPase activation at 10?μM?=?51.1%; FS?=?18.90; EF?=?12.15) and 1-benzyl-3-(3-phenylpropyl)urea (9, cardiac myosin ATPase activation?=?53.3%; FS?=?30.04; EF?=?18.27) showed significant activity in?vitro and in?vivo. The change of phenyl ring with tetrahydropyran-4-yl moiety viz., 1-(3-phenylpropyl)-3-((tetrahydro-2H-pyran-4-yl)methyl)urea (14, cardiac myosin ATPase activation?=?81.4%; FS?=?20.50; EF?=?13.10), and morpholine moiety viz., 1-(2-morpholinoethyl)-3-(3-phenylpropyl)urea (21, cardiac myosin ATPase activation?=?44.0%; FS?=?24.79; EF?=?15.65), proved to be efficient to activate the cardiac myosin. The potent compounds 1, 9, 14 and 21 were found to be selective for cardiac myosin over skeletal and smooth myosins. Thus, these urea derivatives are potent scaffold to develop as a newer cardiac myosin activator for the treatment of systolic heart failure.

In the presence of BF3, a series of symmetrical and unsymmetrical ethers reacted with epichlorohydrin and 2-[(benzyloxy)methyl] oxirane, two terminal epoxides, to afford 1-alkoxy-3-chloropropan-2-ol and 1-alkoxy-3-(benzyloxy)propan-2-ol. The cleavage of unsymmetrical ethers occurred via an SN2 or SN1 mechanism. Secondary epoxides did not give similar ring-opening products. Copyright
