Short antimicrobial lipo-α/γ-AA hybrid peptides.

The last two decades have seen the rise of antimicrobial peptides (AMPs) to combat emerging antibiotic resistance. Herein we report the solid-phase synthesis of short lipidated α/γ-AA hybrid peptides. This family of lipo-chimeric peptidomimetics displays potent and broad-spectrum antimicrobial activity against a range of multi-drug resistant Gram-positive and Gram-negative bacteria.
