A novel series of analogues of (E)-4,5-dihydro-6-[2-[4-(1H-imidazol-1-yl) phenyl]ethenyl]-3(2H)-pyridazinone was synthesized as a variation on the imazodan series. The compounds were evaluated for (i) hemodynamic activity, (ii) cyclic AMP-phosphodiesterase inhibitory activity (human platelets and guinea pig heart tissue), and (iii) platelet aggregation inhibitory activity. The insertion of the ethenyl
合成了(E)-4,5-二氢-6- [2- [4-(1H-咪唑-1-基)苯基]乙烯基] -3(2H)-哒嗪酮的一系列类似物。咪唑烷系列。评价化合物的(i)血液动力学活性,(ii)环状AMP-磷酸二酯酶抑制活性(人血小板和豚鼠心脏组织)和(iii)血小板聚集抑制活性。乙烯基部分在苯基和二氢哒嗪酮环之间的插入产生了新的化合物,这些化合物保留了母体咪唑烷系列的强力肌力/血管扩张活性,并增强了血小板凝集抑制力。在该系列中最有效的化合物3d表现出体内抗血栓形成活性。这些新的哒嗪酮类似物的合成和生物学活性已有报道。
