Description

Oxytocin, 1-(3-Mercaptopropanoic Acid)-8-L-Arginine- CAS NO 38679-66-2 is a synthetic analog of the neuropeptide hormone oxytocin, characterized by a specific modification at the 1-position with 3-mercaptopropanoic acid and at the 8-position with L-arginine. This engineered structure is designed to enhance stability and receptor-binding specificity for advanced research and development applications. It is a critical compound for pharmaceutical researchers, biochemists, and developers in the life sciences sector focusing on neuroendocrinology, peptide therapeutics, and receptor studies.

Application

• Pharmaceutical Research & Development: As a key reference standard and active ingredient in the development of novel peptide-based therapeutics targeting the oxytocin receptor pathway.
• Neurobiological Studies: Used in in vitro and in vivo research to investigate the role of oxytocin and its analogs in social behavior, bonding, stress response, and neuronal signaling.
• Biochemical Assay Development: Serves as a high-purity ligand in receptor binding assays, fluorescence polarization assays, and other high-throughput screening (HTS) platforms.
• Peptide Chemistry & Conjugation: The modified structure provides a reactive thiol group (from mercaptopropanoic acid) for site-specific conjugation, making it valuable for creating labeled probes (e.g., fluorescent, biotinylated) or peptide-drug conjugates.
• Academic Research: Essential for university and institutional labs studying endocrinology, pharmacology, and cellular communication mechanisms.
• Veterinary Pharmaceutical Development: Potential application in research for animal health products, particularly those related to parturition and lactation.
