ABSTRACT The spectrum of activity of ceftaroline was evaluated against 1,247 bacterial isolates representing 44 different species or phenotypic groups. For the majority of species, the activity of ceftaroline was comparable or superior to that of ceftriaxone. MIC and/or disk diffusion quality control ranges of ceftaroline were determined for five standard ATCC reference strains.

AbstractA series of new coumarin derivatives has been synthesized by condensation of 4-chloro-3-nitrocoumarin and the appropriate arylamine and sulfonamide in ethyl acetate in the presence of triethylamine. The synthesized compounds were screened for their in vitro antimicrobial activity against thirteen strains of bacteria and three fungal/yeast strains using disk diffusion assays. They were shown to possess a wide range of activities from almost completely inactive compounds to medium active ones. (4-[(5-Chloropyridin-2-yl)amino]-3-nitro-2H-chromen-2-one) showed similar activity against Klebsiella pneumoniae as tetracycline.
