persistence of ligand-protein interactions over time. Predictions of a favorable substitution of a 5-phenyl group with thiophene and an insertion of a three-methylene spacer between the 5-aromatic and alkyl amino moieties were largely consistent with empirical results. The substitution of a key carboxylate group on the core phenyl ring with tetrazole or truncation of the 5-aryl group reduced affinity. The
P2Y14受体(P2Y14R)通过激活嗜中性粒细胞的运动来介导炎症活动,但已知的拮抗剂种类却很少。我们已经研究了3-(4-苯基-1 H-1,2,3-三唑-1-基)-5-(芳基)苯甲酸拮抗剂支架的结构-活性关系,并通过对接和分子动力学来辅助( MD)在P2Y14R同源性模型上进行仿真。使用高吞吐量MD Python环境的计算管道指导了模拟设计。候选物的选择基于配体-蛋白质的形状和互补性以及配体-蛋白质相互作用随时间的持久性。与噻吩有利地取代5-苯基和在5-芳族和烷基氨基之间插入3-亚甲基间隔基的预测在很大程度上与实验结果一致。核心苯环上的关键羧酸酯基团被四唑取代或5-芳基基团的截短降低了亲和力。使用荧光测定法,最有效的拮抗剂是伯3-氨基丙基同类物20(MRS4458)和苯基对甲酰胺30(MRS4478)。
