A series of new derivatives of 4-hydrazino-5H-pyridazino[4,5-b]indole (5) and 4-hydrazinopyridazino[4,5-a]indole (12) have been synthesized to investigate their activities as selective thromboxane synthetase inhibitors as well as antihypertensive agents. Several of the prepared compounds were found to be selective thromboxane synthetase inhibitors, in concordance with the Gorman model. The most potent
合成了一系列新的4-肼基-5H-哒嗪[4,5-b]吲哚(5)和4-肼基吡啶并嗪[4,5-a]吲哚(12)衍生物,以研究其作为选择性血栓烷合成酶的活性。抑制剂以及降压药。与Gorman模型一致,发现几种制备的化合物是选择性的血栓烷合成酶抑制剂。最有效的是8-(苄氧基)-3,4-二氢-4-氧代-5H-哒嗪[4,5-b]吲哚(3c)和8-甲氧基-4-肼基-5H-哒嗪[4,5 -b]吲哚(5)。该最后一种化合物不抑制前列环素的形成,并且显示出与肼屈嗪相似的降压活性。小鼠5a的急性毒性。HCl约为肼苯哒嗪的2.2倍。
