PT-141

PT-141, also known as bremelanotide, is a synthetic cyclic peptide developed from the α-melanocyte-stimulating hormone (α-MSH) peptide framework. Its defined cyclic structure makes it a compound of interest in laboratory research involving melanocortin receptors, peptide-receptor interactions, and associated molecular signaling pathways.

Bremelanotide is a seven-amino-acid peptide with structural modifications that distinguish it from naturally occurring α-MSH. Laboratory characterization has demonstrated affinity for melanocortin receptor subtypes, including MC1R and MC4R.

This PT-141 product is supplied as a research material for controlled biochemical, receptor-focused, and analytical applications.
