Melanotan II

Melanotan II was originally developed as a synthetic analogue of α-MSH to investigate melanocortin receptor biology. Unlike endogenous α-MSH, Melanotan II exhibits improved stability and prolonged biological activity, allowing researchers to better characterize melanocortin signaling pathways across multiple tissues. Current laboratory research investigates Melanotan II across several areas: Melanogenesis and Pigmentation Biology Melanotan II activates melanocortin receptors on melanocytes, particularly MC1R, stimulating intracellular cAMP signaling and increasing eumelanin synthesis. This pathway has made MT-II an important experimental tool for studying: * Melanin biosynthesis * Pigment cell signaling * UV-response mechanisms * Skin photobiology * Melanocyte physiology ⸻ Melanocortin Receptor Pharmacology Melanotan II functions as a non-selective agonist across several melanocortin receptors including: * MC1R * MC3R * MC4R * MC5R Because these receptors regulate diverse physiological systems, MT-II is frequently used to investigate receptor pharmacology, intracellular signaling cascades, and receptor selectivity in vitro and in animal models. ⸻ Neuroendocrine Research Experimental studies continue to explore melanocortin signaling within the central nervous system, including its roles in: * Appetite regulation * Energy homeostasis * Neuroendocrine pathways * Behavioral neuroscience * Autonomic nervous system signaling These investigations primarily aim to better understand melanocortin receptor function rather than establish therapeutic applications. ⸻ Metabolic Research The melanocortin system is closely linked with whole-body energy regulation. Melanotan II has therefore been utilized experimentally in studies examining: * Food intake regulation * Body weight physiology * Energy expenditure * Metabolic signaling pathways * Central regulation of feeding behavior Research in this area remains primarily preclinical. ⸻ Receptor Signaling Studies Melanotan II serves as a reference compound in laboratories investigating: * GPCR activation * Ligand-receptor interactions * Signal transduction * Receptor internalization * Drug discovery targeting melanocortin pathways Its relatively high potency and stability make it a common experimental standard in melanocortin receptor research. ⸻ Quality Attributes * High-purity peptide suitable for laboratory research * Verified by HPLC analytical testing * Lyophilized powder for long-term storage stability * Manufactured for research applications under quality-controlled conditions ⸻ Important Notice This material is supplied strictly for laboratory research purposes only. * Research Use Only (RUO) * Not approved for therapeutic or diagnostic use * Not intended for human consumption * Not intended for veterinary use * Must be handled only by qualified research professionals Melanotan II is not approved by the U.S. FDA for cosmetic tanning or other clinical use, and health authorities have warned against use of unregulated products marketed for these purposes.
