RESUMEN
Intracellular pathogens can thrive within mammalian cells and are inaccessible to many antimicrobial agents. Herein, we present a facile method of enhancing the cell penetrating and antibacterial properties of cationic amphiphilic polyproline helices (CAPHs) with modifications to the hydrophobic moiety at the N-terminus. These altered CAPHs display superior cell penetration within macrophage cells, and in some cases, minimal cytotoxicity. Furthermore, one CAPH, Pentyl-P14 exhibited excellent antibacterial activity against multiple strains of pathogenic bacteria and promoted the clearance of intracellular Shigella within macrophages.
