Melanotan II acts as a non-selective agonist of the melanocortin receptors MC 1, MC 3, MC 4, and MC 5. [4]Melanotan II produces melanogenesis by activation of the MC 1 receptor, whereas its clinically documented sexual effects are thought to be related to its ability to activate the MC 4 receptor (though the MC 3 is thought to also possibly be involved).
An additional analogue called melanotan II causes enhanced libido and erections in most male test subjects and arousal with corresponding genital involvement in most female test subjects. [9] Bremelanotide (formerly PT-141) which stemmed from melanotan II research is currently under development for its aphrodisiac effects.
They include afamelanotide (melanotan) and melanotan II, the former of which has been approved as a treatment to reduce photosensitivity in erythropoietic protoporphyria in the United States. [3] Bremelanotide , another analogue of α-MSH, is available in the United States not as a photoprotective agent, but for the treatment of hypoactive ...
Bremelanotide is an active metabolite of melanotan II that lacks the C-terminal amide group. [17] Aside from melanotan II and endogenous melanocyte-stimulating hormones like α-MSH, other peptide analogues of the same family as bremelanotide include afamelanotide (NDP-α-MSH), modimelanotide, and setmelanotide.
At therapeutic dose levels, it activates MC1R and MC4R. [16] Setmelanotide (Imcivree) is an MC4R agonist approved for chronic weight management in patients with genetic obesity. [17] [18] Afamelanotide (Scenesse) is an MC1R agonist approved for patients with erythropoietic protoporphyria to increase pain-free light exposure. [19] Clinical trials
A number of products are sold online and in gyms and beauty salons as "melanotan" or "melanotan-1" which discuss afamelanotide in their marketing. [17] [18] [19] Without a prescription, these drugs are not legally sold in many jurisdictions and are potentially dangerous. [20] [21] [22] [23]
PF-00446687 is a drug developed by Pfizer for the treatment of erectile dysfunction, which is a non-peptide agonist selective for the melanocortin receptor subtype MC 4.It was found to be active in preliminary human trials, with the 200mg dose being of similar effectiveness to 100mg sildenafil, though lower doses were ineffective.
Melanotan II; Modimelanotide; Setmelanotide was approved by FDA as first-ever therapy for chronic weight management (IMCIVREE).The setmelanotide was advanced first-in-class, precision medicine that is designed to directly address the underlying cause of obesities driven by genetic deficits in the melanocortin-4 (MC4) receptor pathway.
