Ferrocin B is an iron-containing cyclic decapeptide antibiotic found in the bacterium Pseudomonas fluorescens YK-310, exhibiting strong antibacterial activity primarily against Gram-negative bacteria, with particularly potent inhibitory effects on Pseudomonas aeruginosa. In a mouse infection model, Ferrocin B shows a half effective dose (ED50) of 0.593 mg/kg against P. aeruginosa. Ferrocin B holds potential for research in the field of anti-infective therapies[1].
