the alpha7 subtype of nAchRs, similar to the nonselective AR antagonist caffeine, taken as the reference compound. Along with the pharmacological evaluation, chemical stability of methyl 3-(((6-amino-3,5-dicyano-4-(furan-2-yl)pyridin-2-yl)sulfanyl)methyl)benzoate 10 was assessed in plasma matrices (rat and human), and molecular modeling studies were carried out to better rationalize the available structure-activity
为了进一步研究该支架获得腺苷受体(AR)配体的潜力,合成了一系列新的氨基-3,5-二氰基吡啶(1-31),并对其进行了生物学评估。通常,进行的修饰导致化合物具有高至良好的人(h)A1AR亲和力和反向激动剂谱。尽管大多数化合物是hA1AR选择性的,但某些衍生物的作用类似于混合的hA1AR反向激动剂/ A2A和A2B AR拮抗剂。后者的化合物(9-12)显示,它们通过涉及nAchRs的alpha7亚型的机制减轻了奥沙利铂诱导的神经性疼痛,该机制类似于非选择性AR拮抗剂咖啡因,被用作参考化合物。连同药理学评估,甲基3-(((6-氨基-3,
