A synthetic cyclic analog of alpha-MSH researched for skin tanning and secondarily appetite and sexual function; not approved, with notable safety concerns.
A non-selective melanocortin agonist (MC1R, MC3R, MC4R, MC5R). At skin MC1R it raises cAMP and the PKA-CREB-MITF pathway to drive eumelanin (tanning); centrally MC3R/MC4R suppress appetite and stimulate arousal. It crosses the blood-brain barrier.
