Overview

Melanotan II is a synthetic cyclic heptapeptide analog of α-melanocyte-stimulating hormone. It is a widely studied research probe of the melanocortin-receptor family.

Mechanism & receptor biology

It acts as a non-selective agonist across melanocortin receptors (including MC1R and MC4R). Research examines MC1R-linked pigmentation pathways and MC4R-linked central signaling in model systems.

Research context

Used in melanocortin-pharmacology research as a broad-spectrum reference agonist.
