Abstract
Background: In this article, a series of novel oxazolidinone derivatives containing dithiocarbamate moieties have been designed and synthesized. Methods: Their antibacterial activities were measured against Staphylococcus aureus, vancomycin-resistant Enterococcus faecium (VREF), linezolid-resistant Enterococcus faecalis (LREF) and Streptococcus agalactiae (GBS) by minimal inhibitory concentration (MIC) assays. Results: Dithiocarbamates were found conducive to the maintenance of antibacterial activity. Most of them exhibited potent activity against Gram-positive pathogens comparable to linezolid. The most promising compound A8 showed remarkable antibacterial activity against S.aureus, VREF, LREF, and GBS pathogens with MIC values between 0.25 and 1 μg/mL, which might be a promising drug candidate for further investigation. Conclusion: A series of novel oxazolidinone derivatives containing dithiocarbamate moieties might be promising drug candidates for further investigation.
