Conjugation of Ctx(Ile)-Ha Antimicrobial Peptides to Chitosan Ultrathin Films by -Acetylcysteine Improves Peptide Physicochemical Properties and Enhances Biological Activity.

The importance of obtaining new compounds with improved antimicrobial activity is a current trend and challenge. Some polymers such as chitosan have shown promising bactericidal properties when they are structurally modified, which is due to the binding versatility provided by their free amines. Likewise, antimicrobial peptides (AMPs) have received attention in recent years because of their bactericidal activity that is similar to or even better than that of conventional drugs, and they exhibit a low induction rate of antimicrobial resistance.
