Rattusin and Methods of its Use
Researchers at Oklahoma State University have identified a novel defensin-related antimicrobial peptide, with the minimum inhibitory concentrations (MICs) in the range of 2-8 -M against a broad spectrum of Gram-negative and Gram-positive bacterial strains, including antibiotic-resistant strains. Unlike any defensins, this novel peptide has a unique cysteine-spacing pattern and maintains antibacterial activity in the presence of physiological concentrations of NaCl and MgCl2. In addition, this peptide shows no appreciable toxicity to mammalian cells at up to 100 �M, demonstrating a strong potential in both systemic and topical antibacterial therapies.
