As part of a continuing study, we designed and synthesized four series of 1-phenylimidazole-4-carboxylic acid derivatives as xanthine oxidoreductase (XOR) inhibitors, evaluated their in vitro inhibitory potencies against XOR and hypouricemic effects in mice, and determined their structure-activity relationships (SARs). Most of the compounds exhibited in vitro XOR inhibition at the nanomolar level.
作为一项持续研究的一部分,我们设计并合成了四个系列的作为黄嘌呤氧化还原酶(XOR)抑制剂的1-苯基咪唑-4-羧酸衍生物,评估了它们在小鼠中对XOR和低尿酸作用的体外抑制能力,并确定了它们的结构-活动关系(SAR)。大多数化合物在纳摩尔水平上表现出体外XOR抑制作用。与非布索坦相比(半最大抑制浓度[IC50]值为7.0 nM),化合物Ie和IVa表现出最有希望的XOR抑制作用,IC50值分别为8.0和7.2 nM。在草酸钾/次黄嘌呤诱导的急性和长期高尿酸血症小鼠模型中,化合物Ie和IVa显示出明显的低尿酸潜能(P <0.05),与非布索坦相比稍弱,与之相似,分别。更有趣的是,与长期高尿酸血症小鼠组相比,这两种化合物均具有通过降低肌酐和尿素氮水平来改善肾脏损害的能力(P <0.05),而非布索坦则无明显作用。
