A series of N-arylalkanyl 2-naphthamides (Xa~e), which were predicted from virtual molecular docking on a built xanthine oxidase template as potential inhibitors, were synthesized. Their inhibitory activity against xanthine oxidase was assayed. Among these prepared, compounds Xb (IC50 13.6 μM), Xc (IC50 13.1 μM), and Xd (IC50 12.5 μM) showed comparable inhibitory activity to allopurinol (IC50 22.1 μM)
合成了一系列N-芳基烷基 2-萘酰胺 ( Xa ~ e ),这些化合物是从构建的黄嘌呤氧化酶模板上的虚拟分子对接预测的,作为潜在的抑制剂。测定了它们对黄嘌呤氧化酶的抑制活性。在这些制备物中,化合物Xb (IC 50 13.6 μM)、Xc (IC 50 13.1 μM)和Xd (IC 50 12.5 μM)显示出与别嘌醇(IC 50 22.1 μM)相当的抑制活性。体外测定结果与分子对接分数 Δ G有很好的相关性 = -16.99、-17.66 和 -17.13 Kcal/mol,分别。在氧酸钾诱导的高尿酸血症小鼠模型中,口服Xc - Ac(40mg/Kg)过氧乙酰化Xc可使血尿酸水平较正常对照组降低 60%, 与高尿酸血症小鼠组相比,具有统计学意义 ( p < .01)。
