Abstract

Some coumarin 7-substituted cephalosporins and related sulfones were prepared and an antimicrobial assay was performed. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) carried out on cephalosporins showed a potential activity of some of the synthesized compounds against Gram-positive microorganisms. The tests performed on the corresponding sulfones showed no significant activity, neither as antimicrobial agents nor as inhibitors of beta-lactamase. An association of sulfone 6a with ampicillin was observed to inhibit Gram-positive microorganisms with a lower MIC than for ampicillin alone. (C) 1998 Elsevier Science S.A. All rights reserved.
