A series of 5-thiocarbamate oxazolidinones was prepared and tested for in vitro and in vivo antibacterial activities. The results of in vitro antibacterial activity indicated that the 5-thiocarbamate group was a suitable substituent for the activity by the 5-moderate hydrophilicity. The compounds within a favorable log P value range were found to have potent in vitro antibacterial activity against gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). Compounds 3a and 4h were superior to linezolid in both in vitro and in vivo potency and were considered to be hopeful compounds. We also discuss the pharmacokinetic properties of several compounds in mice.
制备了一系列 5-硫代氨基甲酸酯噁唑烷酮,并对其进行了体外和体内抗菌活性测试。体外抗菌活性结果表明,5-硫代氨基甲酸酯基团具有 5-适度亲水性,是一种合适的活性取代基。在有利的对数值范围内的化合物对革兰氏阳性菌(包括耐甲氧西林金黄色葡萄球菌(MRSA)和耐万古霉素肠球菌(VRE))具有强效的体外抗菌活性。化合物 3a 和 4h 的体外和体内效力均优于利奈唑胺,被认为是有希望的化合物。我们还讨论了几种化合物在小鼠体内的药代动力学特性。
