A new set of amino-3,5-dicyanopyridines was synthesized and biologically evaluated at the adenosine receptors (ARs). This chemical class is particularly versatile, as small structural modifications can influence not only affinity and selectivity, but also the pharmacological profile. Thus, in order to deepen the structure–activity relationships (SARs) of this series, different substituents were evaluated
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
