including the comparative molecular field analysis (CoMFA) method, on 52 antagonists of the A2B adenosine receptor with known biological activity were performed to identify the three-dimensional features responsible for A2B adenosine receptor antagonist activity. On the basis of these and previous results on the potent antagonist effect of 8-pyrazolyl-xanthines at human A2BAR, a new series of compounds
对具有已知生物学活性的52种A 2B腺苷受体拮抗剂进行了分子建模研究,包括比较分子场分析(CoMFA)方法,以鉴定负责A 2B腺苷受体拮抗剂活性的三维特征。基于这些和先前关于8-吡唑基-黄嘌呤对人A 2B AR的强效拮抗作用的结果,合成了一系列新的化合物,并在针对人A 1,A 2A,A 3和A的结合研究中进行了评估。一个2B人工鱼礁。与以前的系列相比,选择性有了显着提高,保持了对人类A 2B的效力如8- [3-(4-氯-6-三氟甲基-1 H-苯并咪唑-2-基-甲氧基)-1-甲基-1 H-吡唑-5-基] -1所示,获得了受体。,3-二丙基-3,7-二氢嘌呤-2,6-二酮衍生物66:K i A 2B = 9.4 nM,IC 50 hA 2B = 26 nM hA 1 / hA 2B = 269,hA 2A / hA 2B > 106,hA 3 / hA 2B > 106。这项研究还导致鉴定了一
