Colistin B sulfate
Colistin B (Polymyxin E2) sulfate is a major component of Colistin (HY-113678) and also an antibacterial agent active against multidrug-resistant Gram-negative bacteria. Colistin B sulfate exerts apoptotic effects on human renal proximal tubular cells. Colistin B sulfate induces mild to moderate renal histological damage in mouse models. Colistin B sulfate can be used in the research of multidrug-resistant Gram-negative bacterial infections.
