studies towards development of new drugs with a lower rate in emergence of bacterial resistance have been conducted. The molecular docking analysis gives a possibility to predict the activity of new compounds before to perform their synthesis. In this work, the molecular docking analysis of 64 Linezolid dipeptide-type analogues was performed to predict their activity. The most negative scores correspond
已经进行了针对细菌耐药性出现率较低的新药开发的全球研究。分子对接分析使人们有可能在进行合成之前预测新化合物的活性。在这项工作中,对64个Linezolid二肽型类似物进行了分子对接分析,以预测其活性。最负的分数对应于六个Fmoc保护的类似物(9as,9bs,9bu,10as,10ax和10ay),其中Fmoc基团在PTC中与Linezolid相互作用。合成了26种不同的Fmoc保护的Linezolid二肽型类似物9(as-bz)和10(as-bz),并在抗菌实验中进行了测试。化合物9as,9ay,9ax,10as,10ay和9bu对临床分离出的A组链球菌显示出显着活性。类似物10ay还显示出对ATCC 25923金黄色葡萄球菌菌株以及MRSA-3,MRSA-4和MRSA-5临床分离株的高活性,MIC值低于利奈唑胺。9bu对结核分枝杆菌的多药耐药临床分离株表现出最高的活性。最后,使用ARPE
