Two short series of compounds with 1H‐indole skeleton, bearing hydantoin and piperazine nuclei respectively, were synthesized. Some compounds of these two series were tested for their calcium‐antagonistic activity on K+‐depolarized smooth muscle (rabbit auricolar artery and guinea‐pig taenia caeci) and their negative inotropic action on atrial muscle from guinea‐pig hearts.
合成了两个具有 1H-吲哚骨架的短系列化合物,分别带有乙内酰脲和哌嗪核。测试了这两个系列中的一些化合物对 K + 去极化平滑肌(兔耳廓动脉和豚鼠绦虫)的钙拮抗活性及其对豚鼠心脏心房肌的负性肌力作用。
