Description

Oxytocin, Penicillamine(1)-Phenylalanyl(2)-Threonyl(4)-Ornithine(8)- is a synthetic, modified peptide analog of the neurohypophysial hormone oxytocin, designed for enhanced stability and specific receptor interaction. This compound is of significant interest in advanced pharmaceutical research and drug development due to its potential as a tool for studying oxytocin receptor pathways. It serves critical roles for researchers and manufacturers in the biotechnology and life sciences sectors, particularly those focused on neuroendocrinology, peptide therapeutics, and high-purity biochemical synthesis.

Application

• Pharmaceutical Research & Development: As a key reference standard and active pharmaceutical ingredient (API) intermediate in the development of novel oxytocin receptor agonists or antagonists.
• Biochemical Research: Utilized in in vitro and in vivo studies to investigate the physiological and behavioral roles of the oxytocin system, including social bonding, stress response, and parturition.
• Peptide Synthesis & Manufacturing: Serves as a high-purity building block for the custom synthesis of complex peptide sequences for clinical and preclinical studies.
• Diagnostic Development: Potential use in the development of immunoassays and other diagnostic tools for measuring oxytocin pathway activity.
• Academic Research: A critical reagent for universities and research institutions studying neuropeptides, G-protein-coupled receptors (GPCRs), and signal transduction mechanisms.
