0]hept- 2-en-2-yl)oxy]-2H-1-benzopyrans and their analogues were synthesized and evaluated on potassium channel opening and hypotensive activities. Compound (-)-13B with a (4-methyl-5-oxo-3,4-diazabicyclo[4.1.0]hept-2-en-2-yl)oxy group for the 4-position of the benzopyran ring was 3 times as potent as EMD 57283 (II), the lead compound, in hypotensive activity. The results would demonstrate that 5-oxo-3,4-diazabicyclo[4
一系列的3,4-二氢-3-羟基-4-[(5-氧代-3,4-二氮杂双环[4.1.0]庚二-2-烯-2-基)氧基] -2H-1-苯并吡喃和合成了它们的类似物,并对钾通道的开放和降压活性进行了评估。对于苯并吡喃环的4-位具有(4-甲基-5-氧代-3,4-二氮杂双环[4.1.0]庚-2-烯-2-基)氧基的化合物(-)-13B为3在降压活动中的功效是主要化合物EMD 57283(II)的两倍。结果表明5-氧代-3,4-二氮杂双环[4.1.0]庚-2-烯-2-基氧基部分作为苯并吡喃型钾通道开放剂的4-位上的取代基是有效的。
