合成了一组新的氨基-3,5-二氰基吡啶,并在腺苷受体 (AR) 上进行了生物学评估。这种化学类别特别通用,因为小的结构修饰不仅会影响亲和力和选择性,还会影响药理学特征。因此,为了加深该系列的构效关系(SAR),在二氰基吡啶支架的不同位置评估了不同的取代基。一般来说,本文报道的化合物显示出纳摩尔级的结合亲和力,并且与人类 (h) A 1和 A 2A AR 的相互作用比与其他亚型的相互作用更好。进行了 hAR 结构的对接研究以合理化观察到的亲和力数据。感兴趣的是化合物1和5, 它可以被认为是泛配体,因为它以相当的纳摩尔结合亲和力结合所有 ARs (A 1 AR: 1 , K i = 9.63 nM; 5 , K i = 2.50 nM; A 2A AR: 1 , K i = 21 nM ;5,Ki = 24 nM;A 3 AR:1,Ki = 52 nM;5,Ki = 25 nM;A 2B AR:1,EC
