Product Description
Mechanism of action
Cefmetazole is a cephamycin-class lactam antibiotic structurally related to cefoxitin. Its 7methoxy substituent confers enhanced stability against many plasmid- and chromosomal-mediated lactamases, including certain ESBLs and AmpC enzymes. It binds penicillin-binding proteins (PBPs), inhibiting the transpeptidation step of peptidoglycan synthesis. This disrupts the bacterial cell wall, leading to osmotic lysis. Cefmetazole has strong activity against anaerobes and challenging gram-negative organisms, including some resistant Enterobacteriaceae.
Benefits and advantages
Used in ESBL/AmpC resistance modelling, anaerobic-pathogen studies, cephamycin SAR profiling, PBP-binding research, lactamase inhibition investigations, and polymicrobial infection modelling. Valuable for exploring lactam stability mechanisms in resistant gram-negative populations.
Side effects and risks
Risks include hypersensitivity, GI disturbances, hepatic enzyme elevation, coagulation interference, and selection of resistant strains. Handle under lactam antimicrobial containment protocols.
