5-Thiourea and 5-dithiocarbamate oxazolidinones were synthesized as a continuation of research on 5-thiocarbonyl oxazolidinone antibacterial agents considering the hydrophobic parameters of the molecule. The structure-activity relationship (SAR) study revealed that the antibacterial activity on 5-thiocarbonyl oxazolidinones was significantly affected by the lipophilicity, especially the calculated
考虑到分子的疏水性参数,对5-硫代羰基恶唑烷酮抗菌剂的研究继续进行,合成了5-硫脲和5-二硫代氨基甲酸酯恶唑烷酮。结构-活性关系(SAR)研究表明,亲脂性显着影响对5-硫代羰基恶唑烷酮的抗菌活性,尤其是计算出的log P值以及5-亲水(或疏水)取代基与疏水(或亲水)之间的平衡苯环上的取代基。发现一些5-硫代羰基恶唑烷酮对革兰氏阳性细菌具有良好的体外抗菌活性,包括耐甲氧西林的金黄色葡萄球菌(MRSA)和耐万古霉素的肠球菌(VRE)。
