PT-141 (bremelanotide) is a cyclic melanocortin analog research peptide focused on MC4R activation, studied in central melanocortin signaling and receptor pathway research.
PT-141, known in literature as bremelanotide, is a cyclic melanocortin research peptide derived from Melanotan 2. It is studied primarily for its activation of the melanocortin-4 receptor (MC4R), a centrally expressed receptor involved in a range of signaling cascades, and serves as a key probe in CNS melanocortin pathway research.
