Extracellular adenosine receptors have been divided into two major subtypes, called A1 and A2. Substitution of the adenosine molecule with appropriate groups at C2 or N6 is known to impart selectivity for the A2 receptor over the A1 receptor. In the present study, we investigated whether substitution at both C2 and N6 would have additive effects on the A2/A1 affinity ratio, thereby providing compounds
细胞外腺苷受体已被分为两种主要的亚型,称为A1和A2。已知在C2或N6处具有适当基团的腺苷分子的取代赋予A2受体相对于A1受体的选择性。在本研究中,我们研究了在C2和N6处取代是否会对A2 / A1亲和力比产生累加效应,从而为化合物提供比目前可用的试剂更高的A2选择性。令人失望的是,仅当在N6处有一个A1选择性基团时,可加性似乎才成立。例如,A1-选择性激动剂N6-环戊基腺苷的2-(苯氨基)取代导致对A2受体的选择性变化了70倍,但对A2-选择性激动剂N6- [2- (3,
