Cefmetazole lactone

CAS: 70993-70-3

Cefmetazole lactone is an antibiotic, classified as a cephalosporin, which is a type of β-lactam antimicrobial compound. It is derived from the Cephalosporium fungus, known for its progenitor antimicrobial properties. As a second-generation cephalosporin, cefmetazole lactone operates by inhibiting bacterial cell wall synthesis, essentially interfering with the transpeptidation process of peptidoglycan, a critical component of the bacterial cell wall. This disruption leads to cell lysis and eventual bacterial death, mainly affecting Gram-positive and some Gram-negative bacteria.
