Abstract
The effects of side chain modification and chirality in linezolid-like 1,2,4-oxadiazoles have been studied to design new potent antibacterials against Gram-positive multidrug-resistant pathogens. The adopted strategy involved a molecular modelling approach, the synthesis and biological evaluation of new designed compounds, enantiomers separation and absolute configuration assignment. Experimental determination of the antibacterial activity of the designed (S)-1-((3-(4-(3-methyl-1,2,4-oxadiazol-5-yl) phenyl)-oxazolidin-2-one-5-yl) methyl)-3-methylthiourea and (S)-1-((3-(3-fluoro-4-(3-methyl-1,2,4-oxadiazol- 5-yl) phenyl)-oxazolidin-2-one-5-yl) methyl)-3-methylthiourea against multidrug resistant linezolid bacterial strains was higher than that of linezolid.
