Description
PT-141, also known as Bremelanotide, is a synthetic cyclic heptapeptide and a potent agonist of melanocortin receptors, primarily MC3R and MC4R. Derived from the α-melanocyte-stimulating hormone (α-MSH), PT-141 is extensively studied for its role in modulating neuroendocrine functions, particularly those related to sexual behavior and arousal mechanisms.
Unlike peripheral agents that target vascular pathways, PT-141 exerts its effects centrally by activating specific receptors in the hypothalamus, thereby influencing sexual desire and arousal through neural pathways
