Description
Cefmetazole is a semisynthetic second generation cephalosporin antibiotic derived from cephamycin. It is effective against a variety of gram-negative and gram-positive bacteria, exhibiting more efficacy against many gram-negative enteric bacteria than many first generation cephalosporins. In addition, cefmetazole has been used to research its effect on the expression and inhibition of the penicillin binding proteins, especially PBP2 and PBP4.
Cephalosporins are a type of β-lactam antibiotic consisting of a four-membered β-lactam ring bound to a six-membered dihydrothiazine ring. This two-ring system causes distortion of the β-lactam amide bond, resulting in decreased resonance stabilization and increased reactivity. β-lactams inhibit the formation of peptidoglycan cross-links within bacterial cell walls by targeting penicillin-binding proteins or PBPs. Consequently, the bacterial cell wall becomes weak and cytolysis occurs. Cephalosporins are less susceptible to β-lactamases than the penicillin β-lactam antibiotics.
