PT141 (Bremenalotide)

PT-141 (also known as bremelanotide) is a synthetic peptide that acts as a melanocortin receptor agonist, primarily engaging central melanocortin pathways (commonly associated with MC3R/MC4R signalling). In research settings, PT-141 is used to study neuroendocrine regulation of sexual motivation and arousal, including central mechanisms involved in libido, reward signalling, and autonomic responses. Because its primary activity is mediated through central nervous system pathways rather than direct vascular mechanisms, it’s frequently referenced in investigations of melanocortin-driven behavioural and physiological responses.
