PT-141, also known as Bremelanotide, is a synthetic peptide derived from the melanocortin hormone family. It has been studied in laboratory settings for its activity at the melanocortin-4 receptor (MC4R), a receptor located in the central nervous system and associated with neuroendocrine signalling.

Research interest in PT-141 has centred on its role in centrally mediated physiological pathways, particularly those involved in behavioural and hormonal responses. It stands out from other compounds due to its mechanism of action through the brain rather than peripheral systems.
