conversion from a hydroxy group to amine group. To further investigate the structure–activity relationships of these pyrimidine-containing xanthine oxidase inhibitors and explore the contribution of amino or hydroxy group on xanthine oxidase inhibitory potency, several 2-phenylpyrimidine derivatives with amino or hydroxy functional group were designed and synthesized. Thereafter, the structure–activity research
黄嘌呤氧化酶是尿酸合成的关键限速酶,因此黄嘌呤氧化酶抑制剂被认为是高尿酸血症和痛风的有希望的治疗方法之一。在我们之前的研究中,一系列 2-(4-alkoxy-3-cyano)phenyl-6-oxo-1,6-dihydropyrimidine-5-carb 酸和 2-(4-alkoxy-3-cyano)phenyl-6-合成亚氨基-1,6-二氢嘧啶-5-羧酸,在体外表现出色黄嘌呤氧化酶抑制效力。有趣的是,分子对接研究表明,这些化合物与黄嘌呤氧化酶的相互作用行为在从羟基转化为胺基后发生了变化。为了进一步研究这些含嘧啶的黄嘌呤氧化酶抑制剂的构效关系并探索氨基或羟基对黄嘌呤氧化酶抑制效力的贡献,设计并合成了几种具有氨基或羟基官能团的 2-苯基嘧啶衍生物。此后,构效研究和分子建模研究证明羟基和氨基可作为药效团元素用于设计2-苯基嘧啶类黄嘌呤氧化酶抑制剂。特别地,优化的化合物,2-(3-cyano-
