Synthesis, biological evaluation of new oxazolidino-sulfonamides as potential antimicrobial agents

Abstract A number of linezolid-like oxazolidino-sulfonamides ( 7a – y and 8a – b ) were designed and synthesized with a view to develop antimicrobial agents with improved properties. Most of the synthesized compounds showed good to moderate activity against a panel of standard Gram-positive and Gram-negative bacteria and fungal strains. The compounds 7i and 7v exhibited significant activity, with a MIC value of 2.0–6.0 μg/mL against a panel of Gram-positive and Gram-negative bacteria. These compounds also showed activity against Candida albicans , with a MIC value of 4.0 μg/mL. A correlation of the antimicrobial activity with calculated lipophilicity values ( C log P ) is also presented.
