腺苷 A 2B受体 (A 2B AR) 的阻断代表了一种潜在的癌症免疫治疗新策略。在本研究中,我们设计、合成并表征了基于 8-对磺基苯基黄嘌呤支架的不可逆 A 2B AR 拮抗剂。通过进行配体洗脱和动力学实验,在基于放射性配体结合和生物发光共振能量转移 (BRET) 的 Gα 15蛋白激活测定中证实了不可逆结合。p -(1-Propylxanthin-8-yl)benzene sulfonyl fluoride ( 6a , PSB-21500) 是本系列中最有效和选择性不可逆的 A 2B AR 拮抗剂,具有明显的 K人类 A 2B AR 的i值为 10.6 nM ,与其他 AR 亚型相比,选择性 > 38 倍。相应的 3-环丙基取代的黄嘌呤衍生物6c (PSB-21502) 具有类似的效力,但与 A 1 - 和 A 2A AR相比没有选择性。反应性磺酰氟基团与延长的黄嘌呤 8-取代基 (
