The antimicrobial peptides and their potential clinical applications.

ABSTRACT: Nowadays, the bacterial drug resistance leads to serious healthy problem worldwide due to the long-term use and the abuse of traditional antibiotics result in drug resistance of bacteria. Finding a new antibiotic is becoming more and more difficult. Antimicrobial peptides (AMPs) are the host defense peptides with most of them being the cationic (positively charged) and amphiphilic (hydrophilic and hydrophobic) α-helical peptide molecules. The membrane permeability is mostly recognized as the well-accepted mechanism to describe the action of cationic AMPs. These cationic AMPs can bind and interact with the negatively charged bacterial cell membranes, leading to the change of the electrochemical potential on bacterial cell membranes, inducing cell membrane damage and the permeation of larger
