PT141 is a highly potent synthetic peptide analogue of α-MSH that may elicit aphrodisiac effects through stimulation of melanocortin receptors. PT141 consists of seven amino acids and is a cyclic, shortened lactam variant of alpha-Melanocyte-stimulating(α-MSH), a multifunctional peptide that regulates a broad array of physiological functions. In studies, bremelanotide was shown to induce lordosis in an animal model and was also effective in treating dysfunction in both men (erectile dysfunction or impotence) and women.

Introduction:
Bremelanotide or PT-141 is the generic term for a new research peptide for use in helping improve sexual dysfunction in men (erectile dysfunction or impotence) as well as helping improve sexual dysfunction in women (sexual arousal disorder).

Bremelanotide, PT-141 does not act on the vascular system like the former compounds but it is known and has been shown to help increase sexual activity in both male and female mammals. Bremelanotide PT-141 allegedly works by activating melanocortin receptors in the brain, therefore helping increase ones sexual stimulation.

Application:
1. Bremelanotide PT 141 was developed from the peptide hormone Melanotan II.

2. Effective in treating sexual dysfunction in men - impotence / erectile dysfunction and premature ejaculation.

3. Effective in treating sexual dysfunction in women - sexual arousal disorder

4. Does not act upon the vascular system.

5. Increases sexual desire via the central nervous system.

6. Increases libido and sexual desire, helps enhance sexual intercourse satisfaction .


Purity
PT-141 has a peptide purity level that exceeds 99.0% as determined by HPLC and MS. This peptide was synthesized with no additives and is supplied as a white lyophilized (freeze-dried) powder.


Usage
Bremelanotide, similarly to its analogues α-MSH and melanotan II, acts as a non-selective agonist of all of the melanocortin receptors except MC2, where it lacks significant affinity. Reported activity of the drug is as follows:
MC1 (Ki = 0.68 nM)
MC2 (Ki > 1000 nM)
MC3 (Ki = 72.07 nM)
MC4 (Ki = 19.25 nM)
MC5 (Ki = 166.8 nM)

Bremelanotide appears to stimulate sexual desire and arousal completely or mostly via activation of the MC4 receptor (the MC3 receptor may also be involved). It modulates inflammation and limits ischemia via activation of the MC1 and MC4 receptors.

According to Palatin Technologies' original 2003 patent for bremelanotide, it possesses approximately 50 times the potency of melanotan II as an inducer of erection in male rats. In addition, it was stated in the patent that the therapeutic window of bremelanotide in animals (specifically, the range of induction of the desired sexual arousal relative to the induction of side effects including nausea, yawning, stretching, and decreased appetite) was >1,000-fold, whereas that of melanotan II was only 3- to 4-fold. They concluded that bremelanotide would be more tolerable than melanotan II.
