Abstract:
Over the last 60 years, only four new classes of antibiotics have been introduced, while the prevalence of antibiotic-resistant Gram-positive and Gram-negative bacteria has risen. This underscores the urgent need for new antibacterial therapeutics. This commentary leverages the recent exploration of γ-substituted-N-acylated-N-aminoethyl amino acid peptides (γ-AApeptides) to mimic the structures and function of natural antimicrobial peptides (AMPs), highlighting the promise and limitations for developing a new, effective treatment for antibiotic-resistant bacteria.
