Melanotan-2 a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH), MT-2 primarily targets the MC1R receptor, which is involved in pigmentation regulation. In laboratory research, MT-2 has demonstrated an ability to stimulate melanin production, leading to visible pigmentation changes in animal models. This property makes it particularly valuable for studies investigating skin protection mechanisms and adaptive coloration.
Beyond pigmentation, MT-2 has been shown to influence energy metabolism, appetite, and exploratory behavior through its interaction with MC3R and MC4R receptors. These broader physiological effects highlight its utility in studying the interconnected pathways of metabolism, neuroendocrine regulation, and behavioral adaptation within research environments.
