  • Xanthine Oxidase Inhibitory and Molecular Docking Studies on Pyrimidones
    作者:Humaira Zafar、Sarosh Iqbal、Sumaira Javaid、Khalid M. Khan、Muhammad I. Choudhary
    DOI:10.2174/1573406413666171129224919

    Background: Xanthine oxidase is an important enzyme which catalyzes the production of uric acid and superoxide anion from xanthine. The over-production of these products leads to different disease conditions. For instance, uric acid is responsible for hyperuricemia, gout, and arthritis, while superoxide anion contributes to the oxidative stress, and related diseases. Hence XO is an important pharmacological target for the treatment of a range of diseases. Methods: Based on the structural resemblance of pyrimidines with xanthine, a series of previously synthesized ethyl 6- methyl-2-oxo-1, 2, 3, 4-tetrahydro-5-pyrimidinecarboxylate derivatives were evaluated for XO inhibitory activity. Results: Among 25 pyrimidone derivatives, 22 were found to be good to weak inhibitors with IC50 values in the range of 14.4 - 418 µM. Compounds 3, 14, 15, 18, and 21-23 were significant inhibitors, and thus analyzed for their kinetic parameters. Among them compounds 14, 15, 18, and 23 were competitive, 21 and 22 showed non-competitive, while 23 was a mixed-type of inhibitor. Molecular docking studies highlighted the interactions of these inhibitors with critical amino acids of XO, such as Val1011, Phe649, Lys771, and others. Moreover, the cytotoxicity studies on these selected inhibitors showed all these compounds to be non-cytotoxic. Conclusion: These non-cytotoxic, significant XO inhibitors can thus be further investigated for the treatment of hyperuricemia, and gout.
    背景:黄嘌呤氧化酶是催化黄嘌呤产生尿酸和超氧阴离子的一种重要酶。这些产物的过度产生会导致不同的疾病。例如,尿酸是高尿酸血症、痛风和关节炎的罪魁祸首,而超氧阴离子则会导致氧化应激和相关疾病。因此,XO 是治疗一系列疾病的重要药理靶点。 方法:根据嘧啶与黄嘌呤结构相似的特点,对之前合成的一系列 6-甲基-2-氧代-1,2,3,4-四氢-5-嘧啶羧酸乙酯衍生物的 XO 抑制活性进行了评估。 结果:在 25 种嘧啶酮衍生物中,有 22 种是良好至较弱的抑制剂,其 IC50 值在 14.4 - 418 µM 之间。化合物 3、14、15、18 和 21-23 具有显著的抑制作用,因此对其动力学参数进行了分析。分子对接研究强调了这些抑制剂与 XO 的关键氨基酸(如 Val1011、Phe649、Lys771 等)之间的相互作用。结论:因此,可以进一步研究这些无细胞毒性的 XO 重要抑制剂,以治疗高尿酸血症和痛风。
