inflammation and cancer. In this paper, a series of bicyclo[3.1.0]hexane-based nucleosides was synthesized and evaluated for their P1 receptor affinities in radioligand binding studies. The study focused on modifications at 1-, 2-, and 6-positions of the purine ring and variations of the 5′-position at the bicyclo[3.1.0]hexane moiety, closing existing gaps in the structure–affinity relationships.

腺苷A 3受体是治疗和诊断炎症和癌症的有希望的靶标。在本文中,合成了一系列基于双环[3.1.0]己烷的核苷,并在放射性配体结合研究中评估了它们对 P1 受体的亲和力。该研究的重点是嘌呤环的 1-、2-和 6-位修饰以及双环[3.1.0]己烷部分 5'-位的变化,以弥补结构-亲和力关系中现有的空白。最有效的衍生物30显示出中等的 A 3 AR 亲和力(K i为 0.38 μM)和高 A 3 R 选择性。在功能性 P2Y 1中进一步评估了在 5'-位置变化的化合物子集R 分析,显示没有脱靶活性。
