The synthesis of spirapril (5), spiraprilat (25), their RSS stereoisomers, and their glycyl (18b) and lysyl (36, 37) analogues is described. These compounds were evaluated in vivo for inhibition of angiotensin converting enzyme (ACE), and selected compounds were evaluated for in vitro ACE inhibition (spirapril ID50 16 micrograms/kg; spiraprilat IC50 0.8 nM, ID50 8 micrograms/kg). In anesthetized rats
描述了spirapril(5),spiraprilat(25),其RSS立体异构体及其甘氨酰(18b)和赖氨酰(36、37)类似物的合成。在体内评估这些化合物对血管紧张素转化酶(ACE)的抑制作用,并对选定的化合物评估体外ACE抑制作用(螺哌普利ID50为16微克/千克;螺旋体IC50为0.8 nM,ID50为8微克/千克)。在麻醉的大鼠中,iv酯5和36比依那普利更有效,而二酸25和37在体外比依那普利拉更有效。在清醒的大鼠中,口服剂量为0.03-1 mg / kg和依那普利(0.1-1 mg / kg)的依那普利(2)具有持续的活性。从这项工作中,选择了spirapril作为抗高血压药进行临床评估。
