four optical isomers of TZC-5665 (1), a candidate for the treatment of congestive heart failure, was achieved by the reaction of chiral diaminopyridazinone (2) with chiral glycidyl ether. (3). The hypotensive and beta-blocking activities of 1 and its optical isomers were examined when given intravenously into anesthetized rats. Furthermore these compounds were evaluated for inhibitory activity on cAMP
通过手性二氨基哒嗪酮(2)与手性缩水甘油醚的反应,实现了TZC-5665的四种旋光异构体(1)的合成,该化合物可用于治疗充血性心力衰竭。(3)。静脉注射麻醉大鼠时,检查了1及其旋光异构体的降压和β阻滞活性。此外,评估了这些化合物对cAMP磷酸二酯酶III的抑制活性。在四种光学异构体中,Ra,Sb-one(1c)具有TZC-5665(1)的基本活性。
