Interestingly, some highly potent antibiotic compounds were found through this synthetic method, and some of them displayed a significant improvement in activity compared with the corresponding 1,4-diacylthiosemicarbazides. Compound 2n was the most active against Staphylococcus aureus with MIC (minimum inhibitory concentration) of 1.56 mg/mL, and compounds 2m and 2q were the most active against Bacillus
开发了一种合成 2-酰基氨基-1,3,4-恶二唑的有用方法。通过在 60 °C 的水中使用碘酸钾作为氧化剂,在两小时内以中等至极好的收率提供了范围广泛的 2-酰基氨基-1,3,4-恶二唑。该方法可以为在药物化学中生成一系列 2-acylamino-1,3,4-oxadiazoles 提供一条简便的捷径。有趣的是,通过这种合成方法发现了一些高效的抗生素化合物,其中一些与相应的 1,4-二酰基氨基硫脲相比,活性有了显着提高。化合物 2n 对金黄色葡萄球菌的活性最强,MIC(最小抑制浓度)为 1.56 mg/mL,化合物 2m 和 2q 对枯草芽孢杆菌的活性最强,MIC 为 0.78 mg/mL。
