Contexto de pesquisa
Perfil de pesquisa de Melanotan II
Melanotan II is a cyclic alpha-MSH analog studied across multiple melanocortin receptors, including MC1R and central MC3R or MC4R pathways. Research covers melanogenesis, receptor selectivity, cyclic-AMP signaling, appetite-related observations, and other central melanocortin responses. This broader receptor profile distinguishes it from Melanotan I, which is generally approached as a more pigment-centered reference, and from PT-141, which is studied primarily for central melanocortin signaling. Melanotan II is best selected for comparative receptor pharmacology where broad melanocortin activity is intentional. Early experimental findings do not establish safety or suitability for personal, cosmetic, or clinical use.
Molecular class
Cyclic seven-residue melanocortin analog
Sequence / composition
An acetylated cyclic alpha-MSH analog containing norleucine and D-phenylalanine residues.
Research design note
Cyclization and non-native residues differentiate this construct from native alpha-MSH and broaden its receptor research profile.
Mecanismo proposto
A cyclic alpha-MSH analog with agonist activity across several melanocortin receptors, including MC1R and central MC3R/MC4R. This broader profile links pigment signaling with appetite, autonomic, and sexual-response pathways.
Efeitos relatados em estudos
- Early human studies reported increased skin pigmentation and spontaneous erectile responses under experimental conditions.
- Animal studies report reduced food intake and changes in energy-balance and central melanocortin signaling.
- Nausea, flushing, yawning, appetite changes, and pigment or nevus changes have been reported or observed.
Desfechos comuns de pesquisa
MC1R, MC3R, and MC4R potency, cyclic AMP, melanin, skin reflectance, food intake, body mass, erectile response, blood pressure, heart rate, nausea, and pigment changes.
Evidências e limitações
Preclinical and limited early human pharmacology exists, but there is no approved Melanotan II product and long-term safety is not established.
