Peptide Therapeutics Versus Superbugs: Highlight on Current Research and Advancements

Antibiotics have saved several millions of lives, but its persistent use of antibiotics in the treatment of various infections, whether bacterial, fungal, viral or parasitic has lead to the development of antibiotic resistance. The rapid emergence of antibiotic resistant strains poses a serious challenge to existing antimicrobial therapies. Due to the increase in drug-resistant pathogens and failure of antibiotics the urgent need for the discovery of novel antimicrobials has been continuously emphasized in the global forum. Here we review about antimicrobial peptides (AMPs), their structural insights and recent developments. We had summarized the major classes, mechanism of action and biophysical parameters that modulate therapeutic potency of AMPs. Also, we had briefed the challenges involved in developing therapeutic peptides and the global market potential for peptide therapeutics.
