A series of linezolid analogues containing a hydrazone moiety were designed, synthesized and evaluated for their antibacterial activity. Most compounds exhibited more potent antibacterial activity against S.aureus, MRSA, MSSA, LREF and VRE pathogens as compared with linezolid and radezolid. Compounds 9a, 9c, 9f, 9g, 10m and 10t were more potent against tested clinical isolates of MRSA, MSSA, VRE and
设计,合成和评估了一系列含有a部分的利奈唑胺类似物的抗菌活性。与利奈唑胺和雷地唑利德相比,大多数化合物对金黄色葡萄球菌, MRSA,MSSA,LREF和VRE病原体表现出更强的抗菌活性。与利奈唑胺相比,化合物9a,9c,9f,9g,10m和10t对MRSA,MSSA,VRE和LREF的临床分离株更有效。化合物9a对人MAO-A表现出与利奈唑胺相当的活性以进行安全性评估,并在人肝微粒体中显示出适度的新陈代谢。最有前途的化合物9a显示针对显着的抗菌活性的金黄色葡萄球菌,MRSA,MSSA,LREF和VRE病原体的0.0675毫克/毫升,分别,为15至30倍利奈唑胺更有效MIC值。
