CAY10742 is an orally bioavailable oxadiazole antibiotic.1 It is active against the Gram-positive bacteria S. aureus, S. epidermidis, S. haemolyticus, B. cereus, B. licheniformis, E. faecalis, and E. faecium (MICs = 1-4 μg/ml), including laboratory strains and clinical isolates with varying degrees of resistance to methicillin, vancomycin, linezolid, and other antibiotics. CAY10742 (40 mg/kg) reduces the number of bacteria in mouse neutropenic thigh models of linezolid-sensitive or -resistant methicillin-resistant S. aureus (MRSA) infection.
