A series of novel pyridazinone derivatives (II) having a phenoxypropanolamine moiety was synthesized. Their hypotensive and β-blocking activities were evaluated after intravenous administration of the compounds to anesthetized rats. Among them, the 5-chloro-2-cyanophenoxy derivative (29) showed the promising dual activities and was selected for further studies.
合成了一系列具有苯氧基丙醇胺结构的新型哒嗪酮衍生物(II)。在静脉注射给麻醉大鼠后,评估了它们的降压和β-阻断活性。其中,5-氯-2-氰基苯氧基衍生物(29)显示出有前途的双重活性,并被选中进行进一步研究。
