Antibacterial and Anti-Inflammatory Activity of Branched Peptides Derived from Natural Host Defense Sequences.

Antibiotic resistance is a major global health threat, necessitating the development of new treatments and diverse molecules to combat severe infections and preserve the efficacy of existing drugs. Antimicrobial peptides (AMPs) offer a versatile arsenal against bacteria, and peptide structure branching can enhance their resistance to proteases and improve their overall efficacy. A small library of peptides derived from natural host defense peptides and synthesized in a tetrabranched form was selected against
