Compound information
What is PT-141?
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analog of α-melanocyte-stimulating hormone (α-MSH). It functions as a non-selective melanocortin receptor agonist with preferential activity at MC3R and MC4R. Studied in laboratory settings for its central nervous system signaling profile, distinct from peripheral vasoactive pathways.
