Melanotan 2
Melanotan 2 is a cyclic lactam analog of alpha-MSH (CAS 121062-08-6) whose defining structural feature is a lactam bridge between Asp5 and Lys10, which enhances metabolic stability relative to the linear parent peptide. Nanomolar affinity at MC1R, MC3R, MC4R, and MC5R defines its pharmacological profile as a non-selective melanocortin receptor agonist and the reference tool compound for broad melanocortin pharmacology research. MC4R-focused investigations specifically deploy it to characterize hypothalamic and limbic signaling pathways in neuronal cell culture models. Supplied lyophilized for in vitro research use only.
