polymyxin b1

Polymyxin B1, a potent antimicrobial lipopeptide derived from Bacillus polymyxa, has potential for treating multidrug-resistant Gram-negative bacterial infections.

Polymyxin B1-i is a polypeptide antibiotic.

Polymyxin B1-D-Leu-d7 TFA is a deuterium-labeled variant of Polymyxin B1. Derived from Bacillus polymyxa, Polymyxin B1 is a potent antibacterial lipopeptide and the major component of Polymyxin B. It disrupts bacterial cell membranes, leading to cell lysis, and is utilized in research on multidrug-resistant Gram-negative bacterial infections.

Polymyxin B1-[13C6,15N] Tfa Salt (Standard) is a reference standard of Polymyxin B1-[13C6,15N] Tfa Salt intended for quantitative analysis, quality control, and related biochemical research applications.

Polymyxin B Sulfate (Poly-RX) is a mixture of polymyxins B1 and B2, obtained from Bacillus polymyxa strains. They are basic polypeptides of about eight amino acids and have cationic detergent action on cell membranes. Polymyxin B Sulfate (Poly-RX) is used for infections with gram-negative organisms, but may be neurotoxic and nephrotoxic.
