MT-2 (Melanotan 2 Acetate)
Melanotan II is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It is a non-selective agonist of melanocortin receptors MC1R through MC5R. Research interest centers on its activation of MC1R (melanogenesis), MC3R and MC4R (metabolic and appetite regulation), and related neuroendocrine signaling.
MT-2 (Melanotan 2 Acetate) definition
MT-2 (Melanotan II) is a synthetic cyclic heptapeptide alpha-melanocyte-stimulating hormone (α-MSH) analog with broader melanocortin-receptor selectivity than MT-1. Research models examine its agonism across MC1R, MC3R, MC4R, and MC5R, supporting comparative pharmacology research on melanocortin pathway signaling. Research use only. Supplied by Nexus Laboratory with batch-level certificate of analysis documenting HPLC purity, mass spectrometry identity, and endotoxin screening.
