  Inotropic, vasodilator and low Km, cAMP-selective, cGMP-inhibited phosphodiesterase (PDE III) inhibitory activities of 4a-methyl-4,4a-dihydro-5H-indeno[1,2-c]pyridazin-3(2H)-ones and 4a-methyl-4,4a,5,6-tetrahydrobenzo[h]cinnolin-3(2H)-ones

  摘要：

  Novel 7-substituted-4,4a-dihydro-4a-methyl-5H-indenol[1,2-c]pyridazin-3[2H]-ones and 8-substituted-4a-methylbenzo[h]cinnolin-3[2H]-ones have been synthesized and their PDE III inhibitory, inotropic and vasodilator potencies compared with those of their normethyl analogues and their bicyclic 4,5-dihydro-6-phenylpyridazinone analogues. The structure-activity relationships of the tricyclic pyridazinones differ from those of bicyclic pyridazinones mainly in respect of the effect of introducing the methyl group into the pyridazinone ring. Whilst in the 4,5-dihydro-6-phenylpyridazin-3(2H)-ones, introduction of a 5-methyl group has been widely reported to lead to compounds of significantly greater potency, the novel tricyclic 4a-methylpyridazinones showed similar levels of inotropic, vasodilator and PDE III inhibitory potency to their normethyl analogues. Possible reasons for this difference in behaviour are discussed.

  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
