Targeted covalent inhibitors of urease were developed on the basis of the catechol structure. Forty amide and ester derivatives of 3,4-dihydroxyphenylacetic acid, caffeic acid, ferulic acid and gallic acid were obtained and screened against Sporosarcinia pasteurii urease. The most active compound, namely propargyl ester of 3,4-dihydroxyphenylacetic acid exhibited IC = 518 nM andk/K = 1379 M s. Inhibitory activity of this compound was better and toxicity lower than those obtained for the starting compound - catechol. The molecular modelling studies revealed a mode of binding consistent with structure-activity relationships.
基于儿茶酚结构，开发了靶向脲酶的共价抑制剂。得到了 3,4-二羟基苯乙酸、咖啡酸、阿魏酸和没食子酸的 40 个酰胺和酯衍生物，并对巴斯德氏固氮螺菌脲酶进行了筛选。最活跃的化合物，即 3,4-二羟基苯乙酸的炔丙酯，表现出 IC=518 nM 和 k/K=1379 M s。与起始化合物儿茶酚相比，该化合物的抑制活性更好，毒性更低。分子建模研究揭示了一种与构效关系一致的结合模式。
