Antibacterial evaluation of compounds I against Staphylococcus aureus and Enterococcus faecalis gave the following results. The 2,4- and 2,5-disubstituted derivatives have weak or no antibacterial activity. Antibacterial activities of 3,4-disubstituted compounds are comparable to those of the 4-monosubstituted analogues for small 3-substituents (smaller than Br), but decline rapidly for larger 3-substituents
合成和结构-活性关系(SAR)的研究对5-(乙酰氨基甲基)恶唑烷酮(I)芳香环中不同的多取代模式对抗菌活性的影响。通过先前描述的六步合成法(Gregory,WA;等人,J.Med.Chem。[公式:参见文本] 1989,32,1673),3-取代的化合物的亲电芳族取代反应制备化合物I,和3,4-二取代化合物的官能团互换反应。化合物I对金黄色葡萄球菌和粪肠球菌的抗菌评价给出以下结果。2,4-和2,5-二取代的衍生物具有弱的或没有抗菌活性。抗菌活性3,对于小的3-取代基(小于Br),4-二取代的化合物与4-单取代的类似物相当,但是对于较大的3-取代基则迅速下降。3,4-环氧基衍生物的活性与其开链类似物相当。3,5-二取代的和3,4,5-和2,4,6-三取代的衍生物没有抗菌活性。
