Cephalosporins

Celphalosporins are a class of β-lactam antibiotics. β-lactams interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBPs are enzymes that catalyze a pentaglycine cross-link between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine cross-link, the integrity of the cell wall is severely compromised, and ultimately leads to cell lysis and death. First generation cephalosporins are typically active against gram-positive bacteria with successive generations having an increasingly broadened activity against gram-negative bacteria. GoldBio’s catalog of cephalosporins contains antibiotics across four generations of cephalosporin activity. Cephalosporins are historically inactive against Listeria, Atypicals (including Mycoplasma and Chlamydia), MRSA, and Enterococci.
