Xanthine oxidase is a complex molybdoflavoprotein that catalyses the hydroxylation of xanthine to uric acid. Fifty three analogues of 1-acetyl-3,5-diaryl-4,5-dihydro(1H)pyrazoles were rationally designed and synthesized and evaluated for in vitro xanthine oxidase inhibitory activity for the first time. Some notions about structure activity relationships are presented. Six compounds 41, 42, 44, 46,
黄嘌呤氧化酶是一种复杂的钼黄素蛋白,可催化黄嘌呤羟化为尿酸。合理设计和合成了1-乙酰基3,5-二芳基-4,5-二氢(1 H)吡唑的53种类似物,并首次评估了其体外黄嘌呤氧化酶抑制活性。提出了有关结构活动关系的一些概念。六种化合物41,42,44,46,55和59被认为是最有效对抗XO带IC 50范围为5.3μM至15.2μM。化合物59成为最有效的XO抑制剂(IC 50 = 5.3μM)。通过分子模拟已经确定了59与XO活性位点氨基酸残基的一些重要相互作用。
