Description

Ranalexin CAS NO 155761-99-2 is a synthetic antimicrobial peptide (AMP) analog, designed to mimic the potent, broad-spectrum activity of natural host defense peptides. This compound matters for its potential to address the critical challenge of microbial resistance, offering a novel mechanism of action that disrupts bacterial cell membranes. It is needed by researchers in pharmaceutical development, biotechnology, and academia focused on next-generation anti-infective agents, as well as by manufacturers in the advanced intermediates sector for high-value active pharmaceutical ingredient (API) synthesis.

Application

• Pharmaceutical Research & Development: As a lead compound or reference standard in the discovery and development of novel antibiotic and antifungal therapies.
• Biochemical Studies: For investigating the structure-activity relationships (SAR) and mechanisms of action of antimicrobial peptides against resistant pathogens.
• Advanced Intermediate: Utilization in the multi-step synthesis of complex peptide-based active pharmaceutical ingredients (APIs).
• Microbiology & Diagnostics: As a tool compound for studying bacterial membrane permeability and developing new antimicrobial susceptibility testing methods.
• Cosmeceutical Applications: Exploration in high-end skincare formulations for its potential preservative and anti-inflammatory properties.
• Veterinary Medicine Development: Research into new therapeutic agents for bacterial infections in animals.
