Description

Pristinamycin CAS NO 270076-60-3 is a synergistic antibiotic complex belonging to the streptogramin class, valued for its potent activity against Gram-positive bacteria, including multidrug-resistant strains. Its primary commercial significance lies in its role as a critical active pharmaceutical ingredient (API) for human and veterinary medicine, addressing the growing global challenge of antimicrobial resistance. This product is essential for pharmaceutical manufacturers, research institutions, and veterinary drug formulators developing targeted therapeutic solutions.

Application

• Pharmaceutical API: Core ingredient in the formulation of human antibiotics, particularly for treating skin, respiratory, and soft tissue infections caused by resistant pathogens.
• Veterinary Medicine: Used in the development of antimicrobial treatments for livestock and companion animals to combat bacterial infections.
• Research & Development: Serves as a reference standard and key intermediate in microbiological research, pharmacology studies, and the development of new antibacterial agents.
• Combination Therapy: Employed in synergistic antibiotic combinations to enhance efficacy and overcome bacterial resistance mechanisms.
