A series of (1H-1,2,3-triazol-4-yl)methoxybenzaldehyde derivatives containing an anthraquinone moiety were synthesized and identified as novel xanthine oxidase inhibitors. Among them, the most promising compounds 1h and 1k were obtained with IC50 values of 0.6 μM and 0.8 μM, respectively, which were more than 10-fold potent compared with allopurinol. The Lineweaver-Burk plot revealed that compound
合成了一系列含有蒽醌部分的(1 H -1,2,3-三唑-4-基)甲氧基苯甲醛衍生物,并将其鉴定为新型黄嘌呤氧化酶抑制剂。其中,获得最有前途的化合物1h和1k的IC 50值分别为0.6μM和0.8μM,与别嘌呤醇相比,具有50倍以上的效力。Lineweaver-Burk图显示化合物1h充当了混合型黄嘌呤氧化酶抑制剂。SAR分析表明,对于抑制效力,苯甲醛部分比蒽醌部分起着更重要的作用。黄嘌呤氧化酶被1h显着抑制的基础 通过分子模型研究合理化。
