A series of 2-phenyl-5-methyl-2H-1,2,3-triazole-4-carboxylic acids/carbohydrazides as analogues of febuxostat were synthesized and evaluated for their in vitro xanthine oxidase (XO) inhibitory activity.
合成了一系列作为非布索坦类似物的2-苯基-5-甲基-2 H -1,2,3-三唑-4-羧酸/碳酰肼,并对其体外黄嘌呤氧化酶(XO)抑制活性进行了评估。
Design, synthesis, and biological evaluation of 5-(4-(pyridin-4-yl)-1<i>H</i>
-1,2,3-triazol-1-yl)benzonitrile derivatives as xanthine oxidase inhibitors
compounds were designed, synthesized, and identified as XO inhibitors. SAR analysis revealed that a carbon atom occupying the X3 position is not as effective as a nitrogen atom, and an iso-pentyloxy or a cyclopentyloxy at the 2-position of benzonitrile moiety will benefit the inhibitory potency. The Lineweaver–Burk plot revealed that compound lk acted as a mixed-type xanthineoxidaseinhibitor and the molecular
