Description

4-[n-Methyl-4-(Methylamino)-L-Phenylalanine]Virginiamycin S1 is a chemically modified derivative of the natural antibiotic Virginiamycin S1, belonging to the streptogramin family. This compound is valued for its role as a key intermediate in advanced pharmaceutical research and development, particularly in the synthesis of novel antimicrobial agents. It is primarily targeted at research institutions, pharmaceutical R&D departments, and fine chemical manufacturers engaged in developing new therapeutic solutions against resistant bacterial strains.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of next-generation streptogramin antibiotics and other antimicrobial compounds.
• Biochemical Research: Used as a reference standard or probe in studies investigating bacterial protein synthesis inhibition and mechanism of action of streptogramins.
• Antimicrobial Development: Employed in R&D programs aimed at creating new drugs to combat multi-drug resistant (MDR) bacterial infections.
• Veterinary Medicine Research: Investigated for potential applications in developing advanced treatments for animal health, building on the history of virginiamycin use.
• Academic Studies: Utilized in university and institutional labs for teaching and research on antibiotic modification and structure-activity relationships (SAR).
