title: Novel 4-N-substituted aryl but-3-ene-1,2-dione derivatives of piperazinyloxazolidinones as antibacterial agents.
abstract: Novel (5S)-N-[3-(3-fluoro-4-{4-[2-oxo-4-(substituted aryl)-but-3-enoyl]-piperazin-1-yl}-phenyl)-2-oxo-oxazolidin-5-ylmethyl]-acetamide 3a-j analogues were synthesized and their in vitro antibacterial activity was evaluated. Most of the compounds of series showed superior in vitro activity against Gram-positive resistant strains than linezolid. Compound 3f is the most potent compound in the series with 0.04-0.39 microg/mL MIC.
