Abstract

An aryl p-(trifluoromethyl) substituent increases the affinity of 1,3-disubstituted 8-phenylxanthines at A2a-adenosine receptors, while having little effect on affinity at A1-adenosine receptors. In contrast, an aryl p-(trifluoromethyl) substituent has little effect on affinity of 3,7-disubstituted and 1,3,7-trisubstituted 8-phenylxanthines. An aryl p-sulfo substituent reduces affinity of all 8-phenylxanthines at A1- and A2a-adenosine receptors. An 8-(trifluoromethyl) substituent markedly reduces affinity of 1,3-dialkylxanthines at both A1- and A2a-adenosine receptors. In contrast, 8-(trifluoromethyl)caffeine retains affinity for A2a-adenosine receptors, but does lose affinity for A1-adenosine receptors. 8-Bromo-, 8-acryl-, and 8-pent-1-enylcaffeines are also selective for A2-adenosine receptors, while 8-cyclobutylcaffeine is nonselective. 8-[trans-2-(tert-butyloxycarbonyl)vinylcaffeine is 20-fold selective for Aza vs A1 receptors.

摘要

芳基对（三氟甲基）取代基可增加1,3 - 二取代8 - 苯基黄嘌呤对A2a - 腺苷受体的亲和力，而对其对A1 - 腺苷受体的亲和力影响较小。相比之下，芳基对（三氟甲基）取代基对3,7 - 二取代和1,3,7 - 三取代8 - 苯基黄嘌呤的亲和力影响较小。芳基对磺基取代基会降低所有8 - 苯基黄嘌呤对A1 - 和A2a - 腺苷受体的亲和力。8 - （三氟甲基）取代基会显著降低1,3 - 二烷基黄嘌呤对A1 - 和A2a - 腺苷受体的亲和力。相比之下，8 - （三氟甲基）咖啡因对A2a - 腺苷受体仍保留亲和力，但对A1 - 腺苷受体则失去亲和力。8 - 溴 - 、8 - 丙烯基 - 和8 - 戊 - 1 - 烯基咖啡因对A2 - 腺苷受体也具有选择性，而8 - 环丁基咖啡因则无选择性。8 - [反式 - 2 - （叔丁氧羰基）乙烯基]咖啡因对A2a受体与A1受体的选择性为20倍。
