Scorpion venom as a source of new antimicrobial agents Abstract The escalating global threat of antimicrobial resistance necessitates urgent discovery of novel therapeutic agents. Scorpion venom, a complex cocktail of bioactive molecules, has emerged as a promising reservoir of antimicrobial peptides (AMPs) with potent activity against multidrug-resistant pathogens. This review comprehensively examines the structural and functional diversity of scorpion-derived AMPs and their therapeutic potential. Scorpion venom AMPs exhibit remarkable structural heterogeneity. Their physicochemical properties, characterized by cationic charge, amphipathicity, and α-helical or β-sheet conformations, underpin their antimicrobial efficacy. These peptides demonstrate broad-spectrum antimicrobial activity encompassing Gram-positive and Gram-negative bacteria, fungi, viruses, and parasites. Mechanistically, scorpion AMPs employ multifaceted strategies including membrane disruption through pore format...
