Tigecycline

Tigecycline is a broad-spectrum glycylcycline antibiotic that binds to the bacterial 30S ribosome, blocking the entry of transfer RNA, which halts protein synthesis and inhibits bacterial growth. It is active against a panel of 1,924 European clinical bacterial isolates including S. aureus, S. epidermidis, S. pneumoniae, E. faecalis, E. faecium, E. coli, K. pneumoniae, P. aeruginosa, and P. mirabilis strains (MICs = In vivo, tigecycline (6.25 mg/kg twice daily for 5 days) decreases levels of C. difficile cytotoxin activity and spore formation in cecum and colon in a mouse model of C. difficile infection. Formulations containing tigecycline have been used in the treatment of a variety of bacterial infections.Formal Name: 4S,7-bis(dimethylamino)-9-[[2-[(1,1-dimethylethyl)amino]acetyl]amino]-1,4S,4aS,5,5aR,6,11,12a-octahydro-3,10,12,12aS-tetrahydroxy-1,11-dioxo-2-naphthacenecarboxamide.
