What is the Meaning of PT-141?

PT-141, or Bremelanotide, is a synthetic peptide analog of alpha-melanocyte-stimulating hormone (alpha-MSH) primarily utilized clinically for the treatment of hypoactive sexual desire disorder (HSDD) in premenopausal women. Although structurally related to tanning agents, its mechanism of action is distinct, focusing centrally on sexual arousal pathways rather than melanogenesis. Its application represents a targeted pharmacological approach to specific aspects of sexual health signaling.

What is the Origin of PT-141?

PT-141 is an abbreviation derived from its research history, specifically from the fact that it was developed by Palatin Technologies and was the 141st compound screened in a specific series. It is a laboratory designation that has become the common nomenclature for this specific therapeutic peptide.

What is the Mechanism of PT-141?

This peptide functions as a potent agonist at the melanocortin receptors, particularly MC3-R and MC4-R, located within the central nervous system, specifically in the hypothalamus. Activation of these receptors modulates dopaminergic pathways that are integral to the brain's sexual response circuitry. Unlike treatments targeting peripheral circulation, PT-141 works directly on the central neuroendocrine regulation of sexual desire.
