A new series of metronidazole-1,2,3-triazole derivatives 6a–o was synthesized and evaluated as Helicobacter pylori urease inhibitors. All the synthesized compounds were more potent than standard inhibitor thiourea against urease. Among the synthesized compounds, compound 6f (IC50 = 1.975 ± 0.25 µM) with inhibitory activity around 11-fols more than thiourea (IC50 = 22.00 ± 0.14 µM) was the most potent
合成了一系列新的甲硝唑-1,2,3-三唑衍生物6a-o,并作为幽门螺杆菌脲酶抑制剂进行了评估。所有合成的化合物都比标准抑制剂硫脲对脲酶更有效。在合成的化合物中,化合物 6f (IC50 = 1.975 ± 0.25 µM) 的抑制活性比硫脲 (IC50 = 22.00 ± 0.14 µM) 高 11-fos 左右,是最有效的化合物。该化合物的动力学研究表明,化合物 6f 以非竞争性模式抑制脲酶。基于分子模型研究,化合物 6f 指向双镍中心,并通过 H 键和 T 形 π-π 疏水相互作用与关键残基 His492 和 Asp633 稳定。此外,它通过与His593和Arg609的相互作用锚定在活性位点腔中的螺旋-转角-螺旋基序上。最后,
