The synthesis of novel 6-[4-(1H-imidazol-1-yl)phenyl]-1,2,4-triazolo[4,3-b]pyridazines 8a-f and related compounds is described. Although the intermediate hydrazine derivatives 7 and 9 possess good positive inotropic activity, the fused bicyclic pyridazines 8a-f are significantly less potent than the 3(2H)-pyridazinone 5. Compounds 8a-f are potent but nonselective inhibitors of cardiac phosphodiesterase
描述了新型6- [4-(4-(1H-咪唑-1-基)苯基] -1,2,4-三唑并[4,3- b ]哒嗪8a-f和相关化合物的合成。尽管中间体肼衍生物7和9具有良好的正性肌力活性,但是稠合的双环哒嗪8a-f的效力明显低于3(2 H)-哒嗪酮5。化合物8a-f是有效的但非选择性的心脏磷酸二酯酶抑制剂。
