Metabolite Identification
Common NameMezlocillin
DescriptionMezlocillin is only found in individuals that have used or taken this drug. It is a semisynthetic ampicillin-derived acylureido penicillin. It has been proposed for infections with certain anaerobes and may be useful in inner ear, bile, and CNS infections. [PubChem]By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, mezlocillin inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that mezlocillin interferes with an autolysin inhibitor.
