Valorphin CAS NO.144313-54-2

Valorphin is a synthetic heptapeptide (H-Val-Val-Tyr-Pro-Trp-Thr-Gln-NH₂) derived from the β-chain of hemoglobin, with a molecular weight of approximately 560.7 Da and CAS number 144313-54-2. Supplied as a high-purity lyophilized powder, it belongs to the hemorphin family and serves as a research tool for studying opioid receptor interactions, neuroimmune signaling, and inflammatory pathways. Its structure includes key residues for receptor recognition and stability, making it valuable for investigating pain modulation, immune regulation, and the cross-talk between the nervous and immune systems in preclinical models.

1.MECHANISM OF ACTION

Valorphin exerts its biological effects primarily through binding to opioid receptors, particularly μ- and δ-opioid receptors, acting as an opioid peptide agonist. Activation of these G protein-coupled receptors leads to inhibition of adenylate cyclase, reduction in cAMP levels, and modulation of ion channel activity, resulting in analgesic and anti-nociceptive effects. Additionally, Valorphin may influence immune cell function and cytokine production through opioid receptor-mediated signaling, contributing to its immunomodulatory properties observed in experimental systems, though its exact receptor subtype selectivity and downstream pathways remain under characterization.

2.PRODUCT INDICATIONS

Valorphin is indicated for research applications in neuropharmacology, immunology, and pain research. It is used in in vitroassays, such as receptor binding studies and functional screenings, to characterize opioid receptor pharmacology and signaling mechanisms. In in vivomodels, the peptide is administered to investigate its effects on pain perception, inflammation, and neuroimmune interactions, providing insights into the role of hemorphins in disease pathophysiology. Valorphin also serves as a reference compound for structure-activity relationship studies and the development of novel opioid-based therapeutics targeting pain and inflammatory disorders.

3.CLINICAL EFFICACY OF PRODUCT

Valorphin has no established clinical efficacy, safety profile, or regulatory approval for human use. Preclinical studies have demonstrated its opioid receptor-mediated analgesic and potential immunomodulatory effects in animal models, but these findings are exploratory and limited to basic research. No controlled clinical trials have been conducted to evaluate its therapeutic benefits, dosing regimens, or adverse effects in humans, and its translation to clinical applications is hindered by insufficient pharmacokinetic, toxicological, and long-term safety data. The peptide remains strictly a research reagent for investigative purposes without validated diagnostic or therapeutic indications.
