Adding Fat Chains to Lactoferricin Peptides Improves Selectivity for Bacteria Over Human Cells

In VitroPreliminary evidence
The takeaway

N-acylation (adding fatty acid chains) of a human lactoferricin-derived peptide improved its selectivity for bacterial membranes over human cell membranes — a chemical modification strategy for safer antimicrobial peptides.

Key finding

N-acylation of a human lactoferricin-derived peptide improved membrane selectivity: maintaining or enhancing antibacterial activity while reducing tox

What the researchers found

N-acylation of a human lactoferricin-derived peptide improved membrane selectivity: maintaining or enhancing antibacterial activity while reducing toxicity to human cells — demonstrating lipid modification as a strategy for improving antimicrobial peptide therapeutic windows.
