series of compounds were designed. The inhibitory activity against XOR of all compounds was evaluated and their structure–activity relationships determined. The inhibitory activity against XOR of compounds I was weak, with a half-maximal inhibitory concentration (IC50) value > 10 μmol, whereas the inhibitory activity of compounds II and III was increased significantly, among which compounds IIIa (IC50 = 26
基于对非布索坦与黄嘌呤氧化还原酶 (XOR) 之间相互作用的分析,采用生物电子等排策略,使用四唑替代非布司他的羧基-噻唑片段。设计了三个系列的化合物。评估了所有化合物对 XOR 的抑制活性,并确定了它们的结构-活性关系。化合物I对XOR的抑制活性较弱,半数抑制浓度(IC 50)值>10 μmol,而化合物II和III的抑制活性显着增加,其中化合物IIIa(IC 50 = 26.3 ± 1.21 纳米)和IIIc(IC 50 = 29.3 ± 0.88 nM) 是最好的。分子对接表明,四唑可以进入活性腔而不是羧基,并保留了非布索坦和 XOR 之间的大部分相互作用。对于化合物III,不存在与异或的 Asn768 和 Thr1010 的氢键,但引入了一些新的相互作用以提高效力。恶嗪酸钾/次黄嘌呤诱导的小鼠急性高尿酸血症模型也显示化合物IIIa、IIIc和IIIe具有显着的低尿酸血症作用(P <
