4,3-e][1,4]diazepin-5(1H)-one (1), a series of isomeric 5-(phenyl-substituted)pyrazolo[4,3-e][1,4] diazepin-8-ones 3a-f were prepared and tested for their ability to bind to the benzodiazepine receptor. All compounds 3a-f display affinities for the benzodiazepine receptor in the microM range of concentration; in particular 5-phenyl-3-methyl-6,7-dihydropyrazolo[4,3-e][1,4] diazepin-8(7H)-one (3a) is
根据利培西m的抗焦虑特性,1-乙基-4,6-二氢-3-甲基-8-苯基吡唑并[4,3-e] [1,4]二氮杂-5(1H)-一(1) ,制备了一系列异构的5-(苯基取代的)吡唑并[4,3-e] [1,4]二氮杂pin-8-酮3a-f,并测试了它们与苯并二氮杂receptor受体结合的能力。所有化合物3a-f在microM浓度范围内均表现出对苯二氮杂receptor受体的亲和力;特别是5-苯基-3-甲基-6,7-二氢吡唑并[4,3-e] [1,4] diazepin-8(7H)-一(3a)在抑制[3H]方面的效力降低了两个数量级。氟硝西epa比地西epa具有更大的结合力,并且对苯并二氮杂receptor受体的亲和力实际上与其结构异构体利培西epa和氯硝西ze的亲和力相当。
