PT-141 (also known as Bremelanotide) is a synthetic cyclic heptapeptide analog of the alpha-melanocyte-stimulating hormone ($\alpha$-MSH) with the amino acid sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH. Originally investigated as a potential sunless tanning agent, it was later discovered to activate specific melanocortin receptors (primarily MC3R and MC4R) in the central nervous system, bypassing the traditional vascular pathway to induce arousal. It is extensively researched for its role in regulating sexual motivation, libido, and physiological arousal responses in both males and females. Preclinical and clinical evaluations focus on its central nervous system mechanisms, its distinct pharmacological profile compared to phosphodiesterase type 5 inhibitors, and its potential applications in treating hypoactive sexual desire dysfunction.
