Description

Dl-Cycloserine CAS NO 68-39-3 is a broad-spectrum antibiotic and a structural analog of the amino acid D-alanine. This compound is valued for its unique mechanism of action, which involves inhibiting bacterial cell wall synthesis, making it a critical agent in research and development. It is primarily utilized by pharmaceutical manufacturers, research institutions, and diagnostic developers working on antimicrobial therapies and biochemical studies.

Application

• Pharmaceutical Intermediate: Serves as a key starting material or active pharmaceutical ingredient (API) in the synthesis of antibiotic formulations.
• Microbiological Research: Used as a selective agent in culture media to study bacterial resistance mechanisms and cell wall biosynthesis.
• Tuberculosis Treatment: Employed as a second-line agent in combination therapies for multidrug-resistant tuberculosis (MDR-TB).
• Enzyme Inhibition Studies: Acts as an inhibitor for alanine racemase and D-alanine:D-alanine ligase in biochemical assays.
• Veterinary Medicine: Incorporated into treatments for bacterial infections in animals.
• Diagnostic Reagent: Used in diagnostic kits and tests for microbial identification and susceptibility testing.
