摘要

The increased incidence of bacterial resistance to available antibiotics represents a major global health problem and highlights the need for novel anti-infective therapies. Antimicrobial peptides (AMPs) represent promising alternatives to conventional antibiotics. AMPs are versatile, have almost unlimited sequence space, and can be tuned for broad-spectrum or specific activity against microorganisms. However, several obstacles remain to be overcome in order to develop AMPs for medical use, such as toxicity, stability, and bacterial resistance. We lack standard experimental procedures for quantifying AMP activity and do not yet have a clear picture of the mechanisms of action of AMPs. The rational design of AMPs can help solve these issues and enable their use as new antimicrobials. Here we provide an overview of the main physicochemical features that can be engineered to achieve enhanced bioactivity and describe current strategies being used to design AMPs.
