Intermedine
Also known as: Intermedin, Melanocyte-stimulating hormone (intermediate lobe), Pars intermedia MSH, β-MSH (in some species)
Summary
Intermedine (also known as α-MSH variant or intermedin in some contexts, but classically refers to the melanocyte-stimulating hormone found in the pars intermedia of the pituitary) is an endogenous peptide hormone. It is a naturally occurring melanocortin peptide structurally related to α-MSH, produced by the pars intermedia of the pituitary gland. It activates melanocortin receptors to stimulate pigmentation and exerts various pleiotropic effects including modulation of inflammation, feeding behavior, and cardiovascular function. It is primarily a research tool and not approved for therapeutic use.
Mechanism of Action
Binds to melanocortin receptors (MC1R, MC3R, MC4R, MC5R) as an agonist; stimulates adenylyl cyclase via Gs protein coupling, increasing intracellular cAMP. Promotes melanogenesis, has anti-inflammatory effects, and influences energy homeostasis.
