This study mainly focused on the modification of the X2 position in febuxostat analogs. A series of 1-phenyl-1H-1,2,3-triazole-4-carboxylic acid derivatives (1a-s) with an N atom occupying the X2 position was designed and synthesized. Evaluation of their inhibitory potency in vitro on xanthine oxidase indicated that these compounds exhibited micromolar level potencies, with IC50 values ranging from
这项研究主要集中在非布索坦类似物中X 2位置的修饰。设计并合成了一系列N原子占据X 2位的1-苯基-1 H -1,2,3-三唑-4-羧酸衍生物(1a-s)。评估其体外对黄嘌呤氧化酶的抑制力表明,这些化合物表现出微摩尔水平的效价,IC 50值为0.21 µM至26.13μM。其中化合物1s(IC 50 = 0.21μM)表现出最有希望的抑制作用,并且其效力比别嘌呤醇高36倍,但仍然比先导化合物Y-700低13倍,这意味着可以在X 2位置稠合的极性原子是效力不佳。Lineweaver-Burk图显示化合物1s作为混合型黄嘌呤氧化酶抑制剂。对结构-活性关系的分析表明,在4'-位的亲脂性醚尾(例如间-甲氧基苯并)具有更大的抑制效力。分子建模为这项研究中观察到的结构-活性关系提供了合理的解释。
