Design and synthesis of biaryloxazolidinone derivatives containing amide or acrylamide moiety as novel antibacterial agents against Gram-positive bacteria

Abstract A series of novel biaryloxazolidinone derivatives containing amide and acrylamide structure were designed, synthesized and evaluated for their antibacterial activity. Most compounds generally exhibited potent antibacterial activity with MIC values of 1 μg/mL against S. aureus, MRSA, MSSA, LREF and VRE pathogens, using linezolid and radezolid as positive controls. Compound 17 exhibited good antibacterial activity with MIC values of 0.5 μg/mL against S. aureus, MRSA, MSSA and VRE and 0.25 μg/mL against LREF. The results indicated that compound 17 might serve as a potential hit-compound for further investigation.
