说明

一般描述

Chemical structure: ß-lactam

应用

Ceftriaxone was 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.

生化/生理作用

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 toxicity.[4]

其他说明

Keep container tightly closed in a dry and well-ventilated place.
