Antimicrobial peptides

Given the low bioavailability of relevant AMPs in nature, biotechnological interventions with genetic engineering and synthetic biology strategies for enhanced AMP synthesis have been a key focus in industry [1]. With this, as synthetic peptide development approaches have improved, the potential of synthetic AMPs to counteract pathogens and emerging infections has grown – they can now be designed with multifaceted mechanisms of action and act as antiviral, antibacterial and antifungal agents.

Key categories of AMPs currently in development include receptor-binding peptides, membrane-active peptides, membrane-lytic peptides and inhibitory peptides (such as cell wall-inhibiting peptides) [2]. AMPs generally affect highly preserved structures and can be used against specific targets such as peptidoglycans in Gram-negative and Gram-positive bacteria, and glucan in the fungal cell wall. Other peptides are particularly active on biofilm destabilizing the microbial communities. Synthetic peptides have also been marked as a potential solution to help combat antibiotic-resistant microbes such as drug-resistant Staphylococcus aureus. They can also act intracellularly – for instance, on protein biosynthesis or DNA replication [3].

As well as mimicking pharmacological properties, structural and amino acid sequence improvements can also be used to address challenges associated with natural AMPs, such as instability when used as a drug, host toxicity, rapid degradation by proteases and loss of activity in presence of serum and high salt concentrations [2,3]. Short-sequence AMPs (<20 amino acids) can be used to combine optimal antimicrobial activity with inexpensive chemical synthesis and modifications required to ensure stability, low toxicity and microbial specificity, and are compatible with large-scale production [4].
