Title: Innovations in Antimicrobial Peptides by Judith H Brown

Introduction

Judith H Brown is an accomplished inventor based in Falls Church, VA (US). She has made significant contributions to the field of antimicrobial peptides, particularly through her innovative research and development of modified peptide analogues.

Latest Patents

Judith H Brown holds a patent for "Antimicrobial magainin modified peptides." This invention focuses on designing and synthesizing peptides that exhibit improved broad-spectrum antimicrobial activity. The modified peptides are created by replacing low helical potential amino acid residues with high helical potential residues. Additionally, modifications to the termini enhance the amphiphilic structures and prolong antimicrobial activity by reducing susceptibility to protease degradation. For instance, residues such as Ser.sup.8, Gly.sup.13, and Gly.sup.18 in magainin II are modified with Ala, which has a higher propensity for helical structure. The patent demonstrates that these modified peptide analogues can exhibit an increase in antimicrobial activity by up to two orders of magnitude, while maintaining low hemolytic activity compared to magainin 1.
