Duramycin is used in medical research and therapeutic development due to its ability to bind to phosphatidylethanolamine, a lipid found in cell membranes. This property makes it valuable in enhancing the delivery of drugs across epithelial tissues, particularly in the lungs. It has been investigated for use in treating cystic fibrosis by improving chloride and fluid transport, helping to clear mucus from airways. Additionally, duramycin shows potential as an antimicrobial agent against certain gram-positive bacteria, although its primary focus in development is for its bioactive effects on cell membrane function and ion transport. It is also explored in topical applications for skin and eye conditions where membrane stabilization and hydration are beneficial.
