PT-141

PT-141 (Bremelanotide) is a synthetic melanocortin receptor agonist primarily studied for its effects on sexual function and arousal.

Key research areas include:

• Stimulation of sexual desire and arousal (in both men and women)

• Activation of MC3 and MC4 melanocortin receptors in the central nervous system

• Potential treatment of hypoactive sexual desire disorder (HSDD)

• Influence on libido independent of hormonal pathways

It is a metabolite-related analog of Melanotan II and has been investigated for its central nervous system effects on sexual motivation and response.
