PT-141 (Bremelanotide) – Synthetic Cyclic Heptapeptide | Research Use Only

PT-141, also known as Bremelanotide (or Bremelanotide acetate in salt form), is a synthetic cyclic heptapeptide derived from alpha-melanocyte-stimulating hormone (α-MSH). It is classified in scientific literature as a melanocortin receptor agonist and is structurally engineered with a lactam-bridged cyclic core.

PT-141 contains an N-terminal acetylation and a cyclic peptide structure designed for enhanced receptor interaction in experimental models.
