Pexiganan Acetate (also known as Locilex, MSI-78, Cytolex, Pexiganan (acetate)) is a metabolic research peptide. Pexiganan Acetate is a cell membrane disrupting agent studied for its antimicrobial properties.

Pexiganan Acetate is an antimicrobial peptide that functions as a cell membrane disrupting agent. It is being investigated for its potential therapeutic applications, particularly in the treatment of diabetic foot infections. Research has included studies on its stability in drug formulations and its efficacy in topical applications compared to systemic antimicrobial therapy for mildly infected diabetic foot ulcers. Pexiganan Acetate has reached Phase 3 clinical trials for diabetic foot.
