study, a number of A- and B-ring carboxylated aurone derivatives were synthesized and evaluated for their ability to inhibit xanthine oxidase in vitro. According to the results obtained, two different ranges of inhibitory activity were observed. The aurones with carboxylic acid group at the 4′-position of B-ring were found to be potent inhibitors of the enzyme with IC50 values in the low micromolar
黄嘌呤氧化酶是治疗高尿酸血症和痛风的潜在靶标。在这项研究中,合成了许多A环和B环羧化的金酮衍生物,并评估了它们在体外抑制黄嘌呤氧化酶的能力。根据获得的结果,观察到两个不同范围的抑制活性。发现在B环的4'-位具有羧酸基团的金黄色素是该酶的有效抑制剂,其IC 50值在低微摩尔范围内。这些化合物的作用比在6-位具有羧基甲氧基的A-环修饰的金酮的作用高约50倍。使用分子对接计算解释了黄嘌呤氧化酶活性位点中羧化金氧烷的结合方式。
