General description

Chemical structure: ß-lactam

Application

Ceftriaxone was used to study drug-induced immune hemolytic anemias, prophylactic strategies to reduce neonatal encephalopathy, pentylenetetrazole-evoked convulsions, 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 toxicity.

This study investigated the hypothesis that ceftriaxone preconditioning ameliorates brain damage in neonatal animals through glutamate transporter 1 (GLT-1) upregulation. Sprague Dawley rats were pretreated with ceftriaxone, erythromycin, minocycline, or saline for 5 consecutive days starting from postnatal day 2

In this paper, the selectively enhanced antibacterial effects of ZnO nanorods with several kinds of conventional medical antibiotics are investigated. Compares to gentamicin, clarithromycin and ofloxacin, ZnO nanorods could obviously achieve synergistic antibacterial effects with ceftriaxone against Escherichia coli (E.

Glutamate is an essential neurotransmitter regulating brain functions. Excitatory amino acid transporter (EAAT)-2 is one of the major glutamate transporters primarily expressed in astroglial cells. Dysfunction of EAAT2 is implicated in acute and chronic neurological disorders, including stroke/ischemia, temporal lobe
