to the benzodiazepine receptor (BZR) in rat brain tissue. The most active compound was the 8-bromo-9-(3-formamidobenzyl) analogue 16 (IC50 = 0.011 microM), which was 1000-fold more active than the parent 9-benzyl-6-(dimethylamino)-9H-purine (1) and nearly as active as diazepam. Although substitution of a m-formamido group and an 8-bromo substituent on 1 imparted potent BZR binding activity, neither
合成了一系列9-(3-氨基苄基)-6-(二甲基氨基)-9H-嘌呤(8)的8-取代类似物,并测试了它们与大鼠脑组织中苯并二氮杂receptor受体(BZR)结合的能力。活性最高的化合物是8-溴9-(3-甲酰胺基苄基)类似物16(IC50 = 0.011 microM),其活性比母体9-苄基-6-(二甲氨基)-9H-嘌呤( 1)几乎与地西epa一样活跃。尽管在1上取代m-甲酰胺基和一个8-溴取代基赋予了强效的BZR结合活性,但16和11个类似物在修饰的Geller-Seifter冲突方案上均未表现出显着的抗焦虑活性。
