Macrolides have been modified to a large extent by structural and functional variants to expand their spectrum of activity and overcome resistance. Ketolides are new generation 14-membered ring macrolides derived by chemical modification of the readily available erythromycin A. We have designed and synthesized bicyclic oxazolidinone-δ-lactones to mimic the "left segment" periphery of ketolides.Key words: macrolide, ketolide, 50S r-RNA, segment mimetics.
