Biological Activity: HB43 is a synthetic amphipathic cationic α-helical peptide, as well as an antibacterial/anticancer peptide. HB43 reduces the number of Methicillin (HY-121544)-resistant Staphylococcus aureus in biofilms in a dose-dependent manner. When loaded into chitosan nanoparticles, it achieves sustained release, and this effect is particularly pronounced under acidic conditions[1][2].
