Description

Argipressin, Pro(4)- CAS NO 112935-95-2 is a synthetic peptide analog of the endogenous hormone vasopressin, specifically modified at the proline-4 position. This modification is critical for enhancing its metabolic stability and receptor selectivity, making it a valuable research and development tool. It is primarily utilized by pharmaceutical researchers, biotech companies, and academic institutions engaged in advanced endocrinology, cardiovascular research, and the development of novel peptide-based therapeutics.

Application

• Pharmaceutical Research & Development: As a reference standard and active pharmaceutical ingredient (API) in the development of vasopressin receptor agonists and antagonists.
• Biochemical Assays: Used in receptor binding studies, signal transduction research, and enzyme inhibition assays to study the vasopressinergic system.
• Endocrinology Studies: Investigation of water balance, blood pressure regulation, and stress response mechanisms in preclinical models.
• Peptide Chemistry: Serves as a key intermediate or model compound for studying peptide stability, structure-activity relationships (SAR), and novel synthetic methodologies.
• Diagnostic Development: Potential use in the calibration and development of diagnostic kits for hormonal disorders.
