【Abstract】 Aim To design and synthesize a ser ie s of new oxazolidinone derivatives and evaluate their antibacterial activities in vitro primarily.Method Ten target compounds were synthesized in several steps with the starting material 3,4-dif l uoronitrobenzene and their antibacterial activities in vitro against Strap hylococcus aureus and Straphylococcus epidermidis were examined respective ly.R esults and conclusion The structures of the ten new compounds were confi rmed by 1H-NMR and MS.Pharmacological tests showed that compound 7f has the same potent antibacterial activity as that of the c ontrol drug linezolid and compoun ds 7a,8c and 8d also have some a ntibacterial activities.更多还原
