Tyrocidine complex is primarily used as an antimicrobial agent due to its ability to disrupt bacterial cell membranes, making it effective against a range of Gram-positive bacteria. It is often employed in research settings to study bacterial resistance mechanisms and membrane interactions. In the medical field, it has been explored for its potential in treating topical infections, particularly in cases where traditional antibiotics are less effective. Additionally, it serves as a tool in biochemistry for understanding peptide-lipid interactions and the structural dynamics of antimicrobial peptides. Its application, however, is limited by its toxicity to human cells, which restricts its use to external or experimental contexts.
