Synthesis and biological evaluation of substituted benzo[h]cinnolinones and 3H-benzo[6,7]cyclohepta[1,2-c]pyridazinones: higher homologs of the antihypertensive and antithrombotic 5H-indeno[1,2-c]pyridazinones

that of acetylsalicylic acid, most of the benzo[h]cinnolinones exhibited significant antihypertensive, inotropic, and antithrombotic properties. In this respect, the 8-amino (3b) and 8-acetylamino (3c) together with the 4,4a-dehydro analogue of 3c (11) were found to possess the most potent and long-lasting antihypertensive activity. In particular, the dextro isomer of 3c was more active than the racemic
几个取代的苯并[h]肉桂酮3和3H-苯并[6,7]环庚[1,2-c]哒嗪酮4被设计为5H-茚并[1,2-c]哒嗪酮2的较不刚性的同类物。合成并测试为抗高血压药,正性肌力药,抗血栓药,抗炎药和抗溃疡药。尽管七元环衍生物仅显示出与乙酰水杨酸相当的抗血栓形成特性,但大多数苯并[h]肉桂醇酮显示出显着的抗高血压,正性肌力和抗血栓形成特性。在这方面,发现8-氨基(3b)和8-乙酰氨基(3c)以及3c(11)的4,4a-脱氢类似物具有最有效和最持久的降压活性。特别地,3c的右旋异构体比消旋形式更具活性,心动过速效应更低。
