fused 5H-pyridazino[4,5-b]indoles (7-10), substituted in positions 1 and 4 by hydrazine and/or amino groups, have been synthesized. These new compounds present a planar topography, a dipole with an adjacent acidic proton, and a basic hydrogen-acceptor site opposite the dipole. These compounds have some resemblance to carbazeram and other pyridazino agents with cardiotonic activity. Some of the new compounds
合成了一些稠合的5H-吡啶并[4,5-b]吲哚(7-10),在1和4位被肼和/或氨基取代。这些新化合物呈现出平面形貌,具有相邻酸性质子的偶极子以及与偶极子相对的碱性氢受体位点。这些化合物与具有强心活性的咔巴zer和其他哒嗪酮剂相似。本文所述的一些新化合物具有肌力活性(表I和II),具有作为血小板凝集抑制剂的补充作用(表III和IV)。1-Hydrazino-4-(3,5-二甲基)-1-pyrazolyl-5H-pyridazino [4,5-b]吲哚盐酸盐(7a.HCl)是文献中描述的第一种具有PDE-抑制剂活性的化合物IV和作为TXA2合成酶的选择性抑制剂(表V)。
