N6-(indol-3-yl)alkyl derivatives of adenosine were synthesized. The adenosine receptor affinity and the antinociceptive activity of these compounds were assessed in binding studies and the phenylbenzoquinone-induced writhing test. Most of these analogues exhibited a potent analgesic activity without side effects. Among them, compound 3c (UP 202-32) bound to A1 (Ki = 110 nM) and A2 (Ki = 350 nM) adenosine receptors
合成了腺苷的新型N6-(吲哚-3-基)烷基衍生物。在结合研究和苯基苯醌诱导的扭体试验中评估了这些化合物的腺苷受体亲和力和抗伤害感受活性。这些类似物中的大多数表现出有效的镇痛活性而没有副作用。其中,化合物3c(UP 202-32)以特定方式与A1(Ki = 110 nM)和A2(Ki = 350 nM)腺苷受体结合,因为它不与许多其他受体(尤其是阿片样物质结合位点)相互作用。苯基苯醌试验(ED50 = 3.3 mg / kg口服)中的抗伤害感受活性被8-环戊基茶碱拮抗,表明腺苷能机制是该化合物观察到的镇痛作用的基础。
