Description:
PT-141 (Bremelanotide, CAS 189691-06-3) is a synthetic cyclic heptapeptide analogue of α-melanocyte-stimulating hormone (α-MSH), featuring the molecular formula C50H68N14O10. As a selective agonist of melanocortin receptors, primarily MC3R and MC4R, it is supplied as a white to off-white lyophilized powder, which is slightly soluble in water (requires sonication) and polar solvents such as DMSO and methanol. This product is light and moisture sensitive, and its stability is maintained for up to 2 years when stored at -20°C in lyophilized form, while reconstituted solutions require storage at 2–8°C and protection from repeated freeze-thaw cycles.
It serves as the key active pharmaceutical ingredient (API) for the treatment of hypoactive sexual desire disorder (HSDD) in premenopausal women, and is also widely applied in scientific research focusing on melanocortin receptor signaling pathways, sexual function regulation, and the development of novel therapies targeting sexual dysfunction and other conditions related to melanocortin receptor modulation.
