Description

N(G)-Aminoarginine is a chemically modified derivative of the essential amino acid L-arginine, featuring an additional amino group on the guanidino side chain. This structural modification makes it a valuable biochemical building block and research tool for studying nitric oxide synthase (NOS) pathways and protein arginylation. It is primarily sought after by researchers and manufacturers in the pharmaceutical, biotechnology, and life science sectors for applications in biochemical research, peptide synthesis, and as a potential precursor for novel therapeutic agents.

Application

• Biochemical Research: Used as a substrate analog or inhibitor in enzymatic studies, particularly for nitric oxide synthase (NOS) and arginase.
• Pharmaceutical Intermediates: Serves as a key building block in the synthesis of novel peptide-based drugs and bioactive compounds.
• Proteomics & Cell Biology: Employed in studies of post-translational modifications, specifically protein arginylation, which regulates protein stability and function.
• Diagnostic Reagent Development: Utilized in the formulation of assay kits and reagents for research and clinical diagnostics related to the urea cycle and arginine metabolism.
• Academic & Industrial R&D: A critical reagent for universities, contract research organizations (CROs), and biotech companies exploring cardiovascular, neurological, and metabolic diseases.
