New adenosine receptor ligands were designed as hybrid structures between previously synthesized substituted dicyanopyridines and aminopyrimidines, yielding two series of cyano-substituted diphenylaminopyrimidines. We were interested in assessing the effect of this substitution pattern on both affinity and intrinsic activity, as the dicyanopyridines comprised both agonists and inverse agonists, whereas
新的腺苷受体配体被设计为先前合成的取代的二氰基吡啶和氨基嘧啶之间的杂化结构,产生了两个系列的氰基取代的二苯基氨基嘧啶。我们感兴趣的是评估这种取代模式对亲和力和内在活性的影响,因为双氰基吡啶既包含激动剂又包含反向激动剂,而原始的氨基嘧啶仅是反向激动剂。已发现,尽管某些化合物也对腺苷A(2A)受体具有亲和力,但新化合物通常对腺苷A(1)受体具有选择性。在cAMP第二信使分析中,这些化合物起反向激动剂的作用,而不是激动剂。在更多的A(1)受体选择性化合物中,有5种(LUF6048),
