RESUMO

BMS 284756 penetrated well into inflamed meninges (44% ± 11%) and produced good bactericidal activity (−0.82 ± 0.22 Δlog10 CFU/ml · h) in the treatment of experimental meningitis in rabbits due to a penicillin-sensitive strain. BMS 284756 monotherapy had a greater potency than the standard regimen of ceftriaxone and vancomycin (−0.49 ± 0.08 Δlog10 CFU/ml · h) against a penicillin-resistant strain (MIC, 4 mg/liter). Even against a penicillin- and quinolone-resistant strain, BMS 284756 showed good bactericidal activity (−0.52 ± 0.12 Δlog10 CFU/ml · h). The antibacterial activity of BMS 284756 was confirmed by time-killing assays over 8 h in vitro.
