novel families of A2B adenosine receptor antagonists were identified in the context of the structural exploration of the 3,4-dihydropyrimidin-2(1H)-one chemotype. The most appealing series contain imidazole, 1,2,4-triazole, or benzimidazole rings fused to the 2,3-positions of the parent diazinone core. The optimization process enabled identification of a highly potent (3.49 nM) A2B ligand that exhibits
在3,4-dihydropyrimidin- 2-2 (1 H)-one化学型的结构探索的背景下,确定了三个新的A 2B腺苷受体拮抗剂家族。最具吸引力的系列包含与母体重氮酮核心的2,3-位稠合的咪唑,1,2,4-三唑或苯并咪唑环。通过优化过程,可以鉴定出对A 1,A 2A和A 3表现出完全选择性的高效(3.49 nM)A 2B配体受体。功能性cAMP实验的结果证实了代表性配体的拮抗作用。通过基于基于人A 2A受体晶体结构构建的受体驱动的对接模型的分子模型研究,证实了该系列中鉴定出的主要SAR趋势。
