摘要: 目的 研究具有抗菌作用的噁唑烷酮衍生物的构效关系。方法 (S)-[3-(3--4-吗啉-4--苯基)噁唑烷-2--5-]-甲醇甲磺酸酯和仲胺的取代反应合成了7(S)-5-氮杂环亚甲基-3-(3--4-吗啉-4--苯基)噁唑烷-2-酮衍生物, 其结构通过1H NMR和元素分析或质谱确证。结果 所合成的7个化合物对所测的20株细菌均没有明显的体外抗菌活性。结论 用氮杂环亚甲基取代吗啉噁酮的5位乙酰胺甲基降低化合物的抗菌活性。

Abstract: Aim To study the structure-activity relationship of antibacterial oxazolidinone derivatives. Methods Seven (S)-5-(heterocycle methylene)-3-(3-fluoro-4-morpholin-4-yl-phenyl)-oxazolidin-2-ones were synthesized by the substitution of (S)-[3-(3-fluoro-4-morpholin-4-yl-phenyl)-oxazolidin-2-one-5-yl]-methanol mesylate with some secondary amines and the structures of the product were confirmed by 1H NMR and elemental analyses or MS. Results None of the seven compounds showed potent activity against the tested 20 strains of bacteria in vitro. Conclusion The replacement of 5-acetylaminometyl of Linezolid by 5-(heterocycle methylene) lost the antibacterial activity.
