Descriptions of PT-141 :

PT-141 or Bremelanotide is the generic term for a research peptide being studied for its possible use in helping to improve sexual dysfunction in both men (erectile dysfunction or impotence) and women (sexual arousal disorder).

PT-141 was developed from the tanning peptide Melanotan 2, which is a synthetically produced variant of a peptide hormone naturally produced in the body that stimulates melanogenesis that is known as alpha-Melanocyte stimulating hormone.

MSH, activates certain melanocortin receptors in the process of exerting its effects. Indeed, MSH also exerts potent influence over lipid metabolism, appetite, and sexual libido. Resultantly,

PT-141 has been shown in studies to exhibit libido-enhancing effects by activating the melanocortin receptors MC1R and MC4R, but not skin tanning. Melanotan 1 and Melanotan 2 have been researched for their use in protecting against the harmful effects of ultraviolet radiation from sunlight due to their melanogenesis-stimulating properties.

PT-141, or bremelanotide, belongs to the new class of synthetic proteins that work as melanocortin agonists. It is a peptidic compound under new drug development process known as palatin technology. Its molecular formula is C50H68N14O10; Its molecular weight/mass is 1025.2.

The similarity of currently available (FDA-approved) mechanisms of medical treatment for ED means that medical practitioners are generally limited to treating patients with adverse reactions to this class (PDE5 inhibitors). As Hellstrom wrote:
The currently available agents of erectile dysfunction (ED) have the same mechanism of action and pharmacological properties. Therefore, they have the same limitations, including the focus on erection as a terminal organ process. One of the relatively undeveloped areas of research is the potential to have central agents to improve male sexual responses. Various neurohormonal and neurotransmitter systems are involved in male sexual responses, including testosterone, dopamine, serotonin and melanocortin systems. Studies are under way to determine the utility of centrally acting drugs as monotherapy or adjunctive therapy in men with ED or other forms of sexual dysfunction. Bremelanotide is a melanocortin agonist that has been tested in men with ED and can prove to be one of the first central acting agents with clinical utility in male sexual dysfunction.
