Impact of chemical modifications on the antimicrobial and hemolytic activity of helical amphipathic peptide Lasioglossin LL-III

Abstract

Insect venom is abundant in potential antimicrobial peptides (AMPs), which can serve as novel alternatives to conventional antibiotics. Among them, Lasioglossin III LL-III) is a promising candidate with a broad spectrum against many fungi strains and both types of bacteria, whereas almost non-toxic to red blood cells. Many chemical approaches have been recently applied to improve its pharmacological properties and provide useful information regarding structure–activity relationships. Hence, this review focused on highlighting the lesson learned from each modification and supporting the future design of potent, selective, and metabolically stable AMPs.
