The Effect of Systematic Structural Modifications on the Antibacterial Activity of Novel Oxazolidinones

A novel series of tetraethylene glycol (TEG) triazolyl and squaramide containing oxazolidinones were synthesized and tested for their antibacterial activity against a selected panel of Gram-positive and Gram-negative bacteria. The 4-TEG-triazolyl derivatives were prepared by ‘click reaction’. The introduction of the TEG and squaramide groups did not favor antibacterial activity. The three nucleoside-containing oxazolidinones were also prepared by ‘click’’ methodology resulted in weak antibacterial activity.
