General Description
PT-141 is an artificially synthesized cyclic heptapeptide derivative, belonging to the class of melanocortin receptor agonists.
Chemical essence of PT-141: It is an analog of alpha melanocyte stimulating hormone (α - MSH), with a molecular formula of C₅₀H₆₈N₁₄O₁₀, and a CAS number of 189691-06-3.
Mechanism of action of PT-141: mainly through the blood-brain barrier, it specifically activates the melanocortin 4 receptor (MC4R) in the hypothalamus and limbic system of the brain, thereby regulating sexual desire and response, which is different from traditional drugs that act on peripheral blood vessels. PT-141 can only be used for laboratory development research.
The Development of PT-141
PT-141 is developed from Melanotan 2 peptide, which has been tested as a sun free tanning agent. In the initial testing, Melanotan 2 did indeed cause tanning, but it also caused unexpected side effects such as sexual arousal and spontaneous erections in nine out of ten initial male volunteer test subjects.
Palatin completed phase 2B clinical trials in premenopausal women with FSD. Preliminary data analysis and top line results are expected to be released in the first half of the fourth quarter of 2012. Research has shown that PT-141 is effective in treating male (erectile dysfunction or impotence) and female (sexual arousal disorder) sexual dysfunction. Unlike Viagra and other related drugs, it does not act on the vascular system, but directly increases libido through the nervous system.
