Melanotan (MT)-II improves impaired social behavior indicators in mouse models of autism spectrum disorder. Melanotan (MT)-II induces weight loss, reduces food intake and exerts anorectic effects. Melanotan (MT)-II increases intracavernous pressure and erectile activity in brown rats. Melanotan (MT)-II can be used in studies related to memory impairment, anxiety, reduced exploratory behavior, autism spectrum disorder, obesity and erectile dysfunction.

Tetracosactide (Tetracosactrin) is an analogue of adrenocorticotrophic hormone (ACTH). Tetracosactide is the agonist for melanocortin-4 receptor (MC4R) that activates human MC4R with an EC₅₀ of 0.65 nM. Tetracosactide can stimulate the release of corticosteroids such as cortisol from the adrenal gland. Tetracosactide is currently used for the research of ulcerative colitis and Crohn's disease, juvenile/adult rheumatoid arthritis and osteoarthrosis.

MK-0493 is an orally active melanocortin-4 receptor (MC4R) agonist. MK-0493 reduces food intake, suppresses weight gain, elevates blood pressure at high doses, and exhibits preclinical erectile regulatory activity. MK-0493 can be used in research related to obesity.
