Description

Polymyxin B is an antibiotic. Polymyxin B inhibits Gram-negative infections by binding to the LPS of the bacterial wall with high affinity. Polymyxin B neutralizes the effect of endotoxin. Polymyxin B induces bacterial death by increasing its permeability. Polymyxin B is used in endotoxemia research[1][3].

In Vitro

Polymyxin B (10 μg/mL, 6 h) decreases the TNF-α and IL-10 production in Human peripheral blood mononuclear cells (PBMC) [3].

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

In Vivo

Polymyxin B (5-20 mg/kg for i.v; once daily for seven days) reaches the nephrotoxicity endpoint at 20 mg/kg instead of 5 mg/kg in Sprague-Dawley rats model[2].
