Introducing all-hydrocarbon staples into short alpha-helical amphipathic antimicrobial peptides increases their hydrophobicity, hydrophobic moment, rigidity and generally alpha-helicity in water. Stapling generally makes the peptides more resistant to proteolytic degradation, particularly those that are doubly stapled. The introduction of olefinic amino acid residues and conformational restriction by stapling make the peptides significantly more hemolytic, and lead to a decrease of their antimicrobial potency against pathogenic bacteria. Unfortunately, the stapling of those peptides is not rendering compounds that would have better pharmacological qualities than the native unmodified potent peptides.
