novel series of 2,6-diaza-5-oxobicyclo[5.4.0]undeca-1(7),8,10-triene derivatives exhibited antagonistic activity for vasopressin V1 and V2 receptors. Most of these compounds were synthesized and showed a high affinity potential for V2 receptor and low to moderate affinity potential for V1 receptor. The most potent and V2-selective compound, N-[4-[2,6-diaza-6-[2-(4-methylpiperazinyl)-2-oxoethyl] -5- oxobicyclo[5
进行本研究以评估新系列的2,6-二氮杂-5-氧代双环[5.4.0] undeca-1(7),8,10-三烯衍生物是否表现出对血管加压素V1和V2受体的拮抗活性。这些化合物大多数都是合成的,对V2受体显示出高亲和力,对V1受体显示出低至中等的亲和力。最有效和V2选择性的化合物N- [4- [2,6-二氮杂-6- [2-(4-甲基哌嗪基)-2-氧代乙基] -5-氧代双环[5.4.0] undeca-1(7 ),8,10-三烯-2-基]-羰基]苯基1] [2-(4-甲基苯基)苯基]-甲酰胺(11b),对V2受体表现出2.9 nM的IC50,对于V1受体表现出200 nM的IC50 , 分别。当对大鼠口服给药时,11b与对照大鼠相比,尿量增加了约18倍。
