详细说明

Sigma Aldrich - C5793

Application
Ceftriaxone is used to study drug-induced immune hemolytic anemias 1, prophylactic strategies to reduce neonatal encephalopathy 2, pentylenetetrazole-evoked convulsions 3, the effect of expression, binding, and inhibition of PDP1 and other penicillin-binding proteins (PBPs) on bacterial cell wall mucopeptide synthesis.
Biochem/physiol Actions
Ceftriaxone is a third-generation cephalosporin antibiotic that disrupts the synthesis of the peptidoglycan layer of bacterial cell walls. It is effective against gram-positive and gram-negative bacteria. Ceftriaxone is thought to increase EAAT2 pump expression in the central nervous system and to reduce glutamatergic toxicity4.
