SUBSTITUTED CYCLOBUTYLAMINE DERIVATIVE

摘要

Substituted cyclobutylamine derivatives with novel structures represented by general formula (I), wherein R1 to R4 and Q represent each a specific substituent and, in particular, Q represents a quinolone derivative of a specific structure. These derivatives are useful as antibacterial compounds which have excellent antibacterial actions over a wide scope of bacteria including gram-negative and gram-positive ones, exert potent antibacterial activities particularly on methicillin-resistant Staphylococcus aureus (MRSA), penicillin-resistant Streptococcus pneumoniae and quinolone-resistant bacteria and are excellent in the in vivo dynamics and safety.
