Melanotan-II Mechanism of action:
Melanotan II acts as a non-selective agonist of the melanocortin receptors, MC1, MC3, MC4, MC5. Like other melanocortinergic peptides, such as the melanocyte-stimulating hormones (MSHs) and afamelanotide, but unlike adrenocorticotropic hormone (ACTH), melanotan II lacks affinity for the MC2 receptor. Reported activity of the drug is as follows:
MC1 (Ki = 0.686 nM)
MC2 (Ki > 1000 nM)
MC3 (Ki = 34.1 nM)
MC4 (Ki = 6.60 nM
MC5 (Ki = 46.1 nM)
The melanogenesis produced by melanotan II is caused by activation of the MC1 receptor, whereas its sexual effects are thought to be related to its ability to activate the MC4 receptor (though the MC3 is thought to possibly also be involved). Other effects of melanotan II, mostly regarded as adverse effects, include flushing, nausea, vomiting, stretching, yawning, and loss of appetite (the last via activation of MC4).
Melanotan II produces bremelanotide, which, comparatively, is reported to be approximately 50-fold more potent as an inducer of sexual arousal in rats, as an active metabolite.
