    Cefiderocol

    NT$12,137.58

    Cefiderocol is a siderophore cephalosporin antibiotic with a catechol moiety on the 3-position side chain.  It has in vitro activity against the non-fermenting Gram-negative bacteria causing urinary tract infections. It combines a catechol-type siderophore and cephalosporin core with side chains similar to cefepime and ceftazidime.

    Mechanism of Action Cefiderocol binds to iron and enters the bacterial cell using the bacteria's own iron transport system to evade the bacterial porin channels, likened to the 'Trojan horse' and the siderophore technology is being explored. Cefiderocol acts by binding to and inhibiting penicillin-binding proteins (PBPs), preventing cell wall synthesis and ultimately causing death of the bacterial cell.
    Spectrum Siderophore antibiotics are effective against an array of ESBLs. They can also enter cells via passive diffusion through porin channels and is stable against all known classes of β-lactamases. Cefiderocol has in vitro and in vivo activity against Gram-negative bacteria including MDR Gram-negative bacteria, including carbapenem-resistant strains of Enterobacteriaceae, Pseudomonas aeruginosa, Acinetobacter baumannii, and Klebsiella pneumoniae.
    Microbiology Applications Cefiderocol (S-649266), a novel siderophore cephalosporin conjugated with a catechol moiety, has a characteristic antibacterial spectrum with a potent activity against a broad range of aerobic Gram-negative bacterial species, including carbapenem-resistant strains of Enterobacteriaceae and nonfermenting bacteria such as Pseudomonas aeruginosa and Acinetobacter baumannii. Cefiderocol has affinity mainly for penicillin-binding protein 3 (PBP3) of Enterobacteriaceae and nonfermenting bacteria similar to that of Ceftazidime.
