cephalothin

Cephalothin is a beta-lactam antibiotic, inhibits class C β-lactamase AmpC (Ki: 0.32 μM).

Cephalothin sodium (Cefalotin) binds to and inactivates penicillin-binding proteins (PBP) located on the inner membrane of the bacterial cell wall. Cephalothin sodium (Cefalotin) is the sodium salt form of cephalothin, a semisynthetic, beta-lactam, the first-generation cephalosporin antibiotic with bactericidal activity. PBPs participate in the terminal stages of assembling the bacterial cell wall, and in reshaping the cell wall during cell division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.

Deacetoxycephalothin is a biochemical.

Deacetylcephalothin Sodium Salt is an impurity in the synthesis of Cefalonium. It used as a long-acting intramammary cerate for the infusion of dairy cows.

Desacetyl cefapirin is an active metabolite of the cephalosporin antibiotic cefapirin .1 Desacetyl cefapirin is active against E. coli, K. pneumoniae, P. mirabilis, and S. aureus with MIC values of 120, 24, 34, and 0.42 μg ml, respectively.References1.
