摘要
目的探究中药复方茵连痛风颗粒中对黄嘌呤氧化酶有抑制作用的活性成分。方法依据文献报道,建立了茵连痛风颗粒中所含化合物的结构数据库;以黄嘌呤氧化酶为靶标,使用Auto Dock Vina软件对这些化合物进行虚拟筛选,并用Auto Dock Tool对代表性活性成分与黄嘌呤氧化酶的作用模式进行了分析。结果茵连痛风颗粒所含物质中有13个化合物与黄嘌呤氧化酶的结合能在-9.0 kcal·mol-1以下,其中主要为黄酮类成分。结合模式分析表明这些活性分子可以与黄嘌呤氧化酶的活性位点形成-相互作用、疏水相互作用和氢键相互作用。结论茵连痛风颗粒中含有黄嘌呤氧化酶抑制剂,可通过降低尿酸的生成发挥抗痛风作用。
