Description

D-Ornithine is a non-proteinogenic amino acid and the D-isomer of the biologically active L-ornithine. This specific enantiomer is a valuable chiral building block and intermediate in organic synthesis and pharmaceutical research. It is primarily utilized in the development of novel bioactive compounds, including enzyme inhibitors and peptide mimetics. Industries such as pharmaceutical R&D, fine chemical synthesis, and academic research require high-purity D-Ornithine CAS NO 348-66-3 for advanced applications.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the research and development of new drug candidates, particularly enzyme inhibitors and receptor antagonists.
• Biochemical Research: Used as a substrate or inhibitor in enzymatic studies to investigate metabolic pathways, such as the urea cycle and polyamine biosynthesis.
• Peptide Synthesis: Incorporated into custom peptides and peptidomimetics to study structure-activity relationships and create novel therapeutic agents.
• Fine Chemical Production: Serves as a starting material or intermediate in the multi-step synthesis of complex, high-value specialty chemicals.
• Nutritional Science Studies: Employed in comparative metabolic studies to understand the differential biological effects of D- and L-amino acid isomers.
• Cosmetic Ingredient Research: Investigated for potential use in advanced skincare formulations targeting cellular metabolism and repair.
