Magainin I is widely studied for its antimicrobial properties, particularly in medical and pharmaceutical applications. It is effective against a broad spectrum of microorganisms, including bacteria, fungi, and viruses, making it a promising candidate for developing new antibiotics, especially in the face of increasing antibiotic resistance. Its mechanism involves disrupting microbial cell membranes, leading to cell death. Additionally, it is explored for use in wound healing and as a coating for medical devices to prevent infections. Research also investigates its potential in cancer therapy, as it can selectively target and destroy cancer cells while sparing healthy ones. Its natural origin and low toxicity enhance its appeal for therapeutic use.
