  摘要：

  合成了几种与N6-苄基腺苷有关的N6-（芳烷基）腺苷，并确定了它们的A1和A2腺苷受体结合亲和力。环状衍生物N6-（1-萘甲基）腺苷产生非常有效的A2激动剂（A1 Ki = 24 nM，A2 Ki = 9.1 nM），而N6-（9-蒽基甲基）腺苷实际上是无活性的（A1 Ki = 9,000 nM ，A 2 Ki = 29,000 nM）。有趣的是，结构相似的N6-（9-芴基甲基）腺苷是迄今为止报道的最有效的A2激动剂，A2结合的Ki为4.9 nM，A1结合的Ki为5.1 nM。N6-9-芴基腺苷和N6- [2-（9-芴基）乙基]腺苷的同系物对任一腺苷受体显示很少或没有活性。这些试剂对离体大鼠心脏的心率和冠状动脉血流的影响分别与其A1和A2结合亲和力平行。

  Previous structure-coronary vasoactivity correlations of the N6-alkyladenosine analogues of N6-[(R)-1-phenyl-2-propyl]adenosine, 1, support the hypothesis that the coronary artery A2 adenosine receptor contains an N6 region of specialized structure. The part of this receptor region that binds the 2-propyl moiety of 1 determines stereoselectivity and contributes to coronary vasoactivity. The present study uses 92 adenosine analogues containing an aryl group in the N6 substituent to test the hypothesis that the N6 receptor region contains an aryl subregion that binds the phenyl moiety of 1 and thereby contributes to its coronary vasoactivity. N6-Aralkyladenosines are often more potent than their alkyl congeners. Two methylene residues seem to provide optimum separation of the aryl group from N6. Among adenosines with semirigid N6 substituents, N6-[(1R,2S)-trans-2-phenylcyclohexyl]adenosine was uniquely active, evidence that when 1 occupies the receptor, the axis of the propyl C-1 to phenyl C-1 bond is nearly in the plane described by N6 and propyl C-1 and C-2. The torsion angle around this bond is unknown. Replacing the phenyl group of N6-2-phenethyladenosine with a thienyl or a 3-pyridyl group raises activity. The structure-activity relationships of the N6-(arylethyl)-, the N6-(arylmethyl)-, and the N6-phenyladenosines differ strinkingly from each other. Taken together, such results support the idea that the N6 region of the dog coronary artery A2 adenosine receptor includes an aryl subregion.
