General description

Melanotan II induces melanogenesis and thus increases skin pigmentation. It is an analog of α-melanocyte stimulating hormone.

Application

Melanotan II acetate salt has been used to study its inhibitory effects on feeding and energy expenditure in rats.

Biochem/physiol Actions

Melanotan II is a MC3-R/MC4-R melanocortin agonist.
