Corynecin II is a chloramphenicol-like antibiotic originally isolated from Corynebacterium. It inhibits the growth of Gram-positive and Gram-negative bacteria, including S. faecalis, S. aureus, B. subtilis, E. coli, P. aeruginosa, P. vulgaris, S. sonnei, S. typhosa, and K. pneumoniae (MICs = 5.2-83 μg/ml).
Corynecin II is a member of a naturally-occurring complex of chloramphenicol-like acyl nitrophenylpropylamines isolated from Corynebacterium hydrocarboclastus in 1972. Corynecin II is active against Gram positive and Gram negative bacteria. Although less potent than chloramphenicol, corynecin II shows a similar species selectivity.
