Description

Mersacidin CAS NO 128104-18-7 is a potent type B lantibiotic, a class of peptide antibiotics characterized by post-translationally modified amino acids. This compound matters for its significant antimicrobial activity, particularly against Gram-positive bacteria, including methicillin-resistant *Staphylococcus aureus* (MRSA). It is primarily needed by researchers in pharmaceutical development and microbiology for studying novel antibiotic mechanisms and by manufacturers exploring its potential in therapeutic and preservative applications.

Application

• Antimicrobial Research: A key tool for studying the structure, biosynthesis, and mode of action of lantibiotics against resistant bacterial strains.
• Pharmaceutical Development: Serves as a lead compound or model for developing new anti-infective agents targeting drug-resistant pathogens.
• Microbiological Studies: Used in laboratory settings to investigate bacterial cell wall biosynthesis and inhibition mechanisms.
• Biochemical Reagent: Employed as a standard or reference material in assays measuring antimicrobial potency or lantibiotic activity.
• Preservative Exploration: Potential application in research for developing natural preservative systems in specific controlled environments.
