In the present work, the urease inhibition activity of 1,3,4-oxadiazole bearing molecules was evaluated and were found to be potential inhibitors. 3,4-(Methylenedioxy)benzoic acid (1) was employed to synthesize 5-(3,4-methylenedioxyphenyl)-1,3,4-oxadiazol-2-thiol (4) via a series of steps. It was further stepped to yield S-substituted-5-(3,4-methylenedioxyphenyl)-1,3,4-oxadiazole derivatives (6a-h) on reaction with alkyl/aralkyl halides (5a-h) in DMF using LiH as an activator. All the synthesized compounds were well supported by IR, 1H NMR and EIMS spectral analysis. The enzyme inhibition activity against urease enzyme showed these molecules as potent inhibitors of this enzyme.
在本研究中,评估了含有1,3,4-噁二唑基团的化合物的尿素酶抑制活性,发现它们具有潜在的抑制作用。通过一系列步骤,使用3,4-亚甲二氧基苯甲酸(1)合成了5-(3,4-亚甲二氧基苯基)-1,3,4-噁二唑-2-硫醇(4)。进一步通过与烷基/芳烷基卤化物(5a-h)在DMF中使用LiH作为活化剂反应,生成了S-取代的5-(3,4-亚甲二氧基苯基)-1,3,4-噁二唑衍生物(6a-h)。所有合成的化合物均通过IR、1H NMR和EIMS光谱分析得到良好支持。对尿素酶的酶抑制活性显示这些分子是该酶的强效抑制剂。
