Description

Oxytocin, 1-Penicillamyl-Leu(2)- is a synthetic derivative of the neuropeptide hormone oxytocin, modified with a penicillamine group at the N-terminus. This structural modification is significant for research into receptor binding, stability, and the development of novel peptide-based therapeutics and biochemical tools. It is primarily utilized by pharmaceutical R&D departments, academic research institutions, and biotechnology companies focused on neuroendocrinology and peptide chemistry.

Application

• Biochemical Research: Used as a reference standard or probe in studies of oxytocin receptor (OTR) interactions, binding affinity, and signal transduction pathways.
• Pharmaceutical Development: Serves as a key intermediate or model compound in the design and synthesis of novel peptide analogs with potential therapeutic applications.
• Neuroscience Studies: Employed in experimental models to investigate the role of oxytocin and its analogs in social behavior, stress response, and neuronal function.
• Stability & Metabolism Studies: The modified structure makes it valuable for researching peptide stability, degradation pathways, and metabolic fate.
• Diagnostic Tool Development: Can be utilized in the development of immunoassays or other diagnostic methods for detecting oxytocin-related activity.
