A new series of 8-(p-substituted-phenyl/benzyl)xanthines has been synthesized and evaluated in vitro for adenosine receptor binding affinity and in vivo for bronchospasmolytic effects. It was observed that the nature of substituent at para-position of 8-phenyl/benzyl group on the xanthine scaffold remarkably affects the binding affinity and selectivity of xanthine derivatives for various adenosine receptor
已经合成了一系列新的8-(对-取代的苯基/苄基)黄嘌呤,并在体外评估了腺苷受体的结合亲和力,在体内评估了支气管痉挛作用。据观察,取代基在性质对位上的黄嘌呤骨架8-苯基/苄基的-位显着地影响各种腺苷受体亚型以及它们的支气管痉挛的效果的结合亲和力和黄嘌呤衍生物的选择性。新合成的8-苯基黄嘌呤对A 2A受体显示有效的结合亲和力和明显的选择性,并且还产生有效的支气管痉挛作用。在C 8上用苄基部分取代苯环 黄嘌呤骨架的分离导致腺苷受体亲和力和支气管溶解作用显着降低。
