Description

Cecropin B CAS NO 80451-05-4 is a cationic antimicrobial peptide originally isolated from the hemolymph of the giant silk moth, *Hyalophora cecropia*. This compound is of significant interest due to its potent, broad-spectrum activity against bacteria, fungi, and certain parasites, offering a promising alternative to conventional antibiotics. It is primarily utilized in advanced research and development within the pharmaceutical, biotechnology, and life sciences sectors, particularly for studying novel antimicrobial mechanisms and developing new therapeutic agents.

Application

• Antimicrobial Research: Fundamental and applied research into novel mechanisms of action against drug-resistant bacterial and fungal strains.
• Pharmaceutical Development: Serves as a lead compound or model for the design and synthesis of new peptide-based antibiotic therapies.
• Biotechnology & Life Sciences: Used in studies of innate immunity, peptide structure-activity relationships (SAR), and host-defense peptide engineering.
• Biomaterial Coatings: Investigation into surface functionalization for medical devices and implants to prevent biofilm formation and microbial colonization.
• Veterinary Medicine: Exploration of applications in animal health for treating infections, given its natural origin and potent activity.
• Cosmeceutical Research: Potential use in developing preservative systems or active ingredients for skincare formulations targeting microbial issues.
