[Tyr9]- β-MSH (porcine); (Tyr49)-β-Lipotropin (41-58) (porcine) CAS NO.198281-81-1

[Tyr⁹]-β-MSH (porcine); (Tyr⁴⁹)-β-Lipotropin (41-58) (porcine) is a high-purity synthetic peptide representing two distinct but related porcine-derived sequences: the Tyr⁹-modified form of β-melanocyte-stimulating hormone (β-MSH) and the Tyr⁴⁹-modified fragment of β-lipotropin (41-58). Both sequences are derived from the same precursor protein and share melanocortin receptor binding properties. Manufactured under stringent quality controls with HPLC-verified purity and comprehensive analytical documentation, this dual-sequence product provides researchers with a species-specific tool for studying melanocortin system function, receptor pharmacology, and comparative endocrinology in porcine models and related research systems.

1.MECHANISM OF ACTION

This product contains two bioactive peptide sequences that primarily function through activation of melanocortin receptors (MC1R, MC3R, MC4R, MC5R). Upon receptor binding, these peptides activate G-protein coupled signaling pathways, leading to increased intracellular cAMP levels through adenylate cyclase activation. The downstream effects include regulation of melanogenesis (pigment production), energy homeostasis, appetite regulation, anti-inflammatory responses, and neuroendocrine functions. The Tyr⁹ modification in β-MSH and Tyr⁴⁹ modification in β-lipotropin fragment may influence receptor binding affinity, metabolic stability, or signaling potency compared to native sequences, making this product valuable for structure-activity relationship studies and receptor pharmacology research.
