1

A synthetic cyclic lactam heptapeptide analogue of the endogenous hormone alpha-melanocyte-stimulating hormone (α-MSH), investigated for potent and selective agonism at melanocortin-3 and melanocortin-4 receptors. Studied in preclinical neuroendocrine research for MC3-R/MC4-R receptor binding kinetics, downstream cAMP and IP3 signalling cascade activation, melanocyte pigment production pathway modulation, and appetite regulation mechanisms. Used as a research tool in melanocortin receptor selectivity profiling, appetite suppression pathway mechanistic studies, and comparative α-MSH analogue receptor interaction studies.

Frequently Asked Questions

Melanotan II is a synthetic cyclic heptapeptide analogue of alpha-melanocyte stimulating hormone (alpha-MSH). It is a non-selective melanocortin receptor agonist that activates MC1R, MC3R, MC4R, and MC5R, producing a broader pharmacological profile than selective agonists.
