The synthesis and antibacterial activity of several new 5-((3-oxoisothiazol-2(3H)-yl)methyl)-3-phenyloxazolidin-2-ones 8 and analogous 2-(4-substituted phenyl)-3(2H)-isothiazolones 3 and 4 substituted at 4 and/or 3-positions of the phenyl moiety with different groups of which some have shown to increase the antibacterial activity of both 3-aryl-2-oxazolidinones and 3(2H)-isothiazolones is described
几种新的5-((3-oxoisothiazol-2(3H)-yl)methyl)-3-phenyloxazolidin-2-ones 8和类似的2-(4-取代苯基)-3(2H)-的合成及抗菌活性描述了在苯基部分的4和/或3位被不同基团取代的异噻唑酮3和4,其中一些已显示出增加3-芳基-2-恶唑烷酮和3(2H)-异噻唑酮的抗菌活性。活性最高的化合物是异噻唑基恶唑烷酮8a,未取代的j和8b具有4-F取代苯环的化合物,对某些测试的微生物显示出比类似的3(2H)-异噻唑酮更高的活性,并且与利奈唑胺,万古霉素和环丙沙星具有可比或更高的活性。F的位置变化和/或使用较大的取代基使化合物的活性降低或没有活性。对小鼠成纤维细胞(NIH / 3T3)细胞的细胞毒性评估表明,这些化合物在非细胞毒性浓度下具有抗菌活性。
