Design, synthesis and biological evaluation of N-(4-alkoxy-3-(1H-tetrazol-1-yl)phenyl) heterocyclic aromatic amide derivatives as xanthine oxidase inhibitors
amide framework of N-(4-((3-cyanobenzyl)oxy)-3-(1H-tetrazol-1-yl)phenyl)isonicotinamide (compound 1) reported in our previous work, a series of N-(4-alkoxy-3-(1H-tetrazol-1-yl)phenyl) heterocyclicaromatic amide derivatives were designed, synthesized and evaluated as novel amide-based XO inhibitors. Structure-activity relationship campaign identified the most promising compound g25 (IC50 = 0.022 μM), which
黄嘌呤氧化酶(XO)是一种黄素蛋白,存在于各种生物体中,可催化人体内尿酸的形成。基于我们之前工作中报道的N -(4-((3-cyanobenzyl)oxy)-3-(1 H -tetrazol-1-yl)phenyl)isoicotinamide (compound 1 ) 的酰胺骨架,一系列N - (4-alkoxy-3-(1 H -tetrazol-1-yl)phenyl) 杂环芳族酰胺衍生物被设计、合成和评估为新型酰胺基 XO 抑制剂。构效关系活动确定了最有希望的化合物g25 (IC 50 = 0.022 μM),它具有特殊的 1 H-imidazole-5-carboxamide 支架并呈现出与托吡司他相当的 XO 抑制效力 (IC 50 = 0.017 μM)。酶动力学研究表明,化合物g25是一种混合型 XO 抑制剂。分子对接和分子动力学表明,g25 的咪唑 NH与XO 的 Glu1261

There are two symmetry-independent molecules in the unit cell of the title compound, C(7)H(5)N(5)O(3). The tetrazole and phenyl rings are essentially planar and are not coplanar in either molecule [dihedral angles 30.2 (1) and 7.0 (1) degrees]. In the structure, four molecules are connected by O-H...N bridges, forming four-membered molecular aggregates which are linked together by a complex three-dimensional hydrogen-bond network.
