Descripciòn

Polymyxin B Sulfate is a potent antibacterial agent and a relatively toxic antibiotic. Polymyxin B Sulfate also is a antiendotoxin agent. Polymyxin B Sulfate shows endotoxin-neutralizing properties can be used as adjunctive research in gram-negative sepsis. Polymyxin B Sulfate shows antibacterial activities in vitro and in vivo[1][2][3].

In Vitro

Polymyxin B Sulfate shows antibacterial activities with MICs of 0.5 mg/l for E. coli strain IH3080[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Polymyxin B Sulfate (0.5-120 mg/kg; s.c.) shows antibacterial activities in thigh or lung infection mouse model[2].
Polymyxin B Sulfate (2 mg/kg, s.c.) shows potent in mouse bactericidal effect against E. coli strain IH3080[3].
