Research interest
Why researchers are interested
Brief notes on why PT-141 (Bremelanotide) appears in laboratory study designs. Research use only — not for human or veterinary use.
- Researchers are studying bremelanotide for melanocortin receptor signaling on the bench.
- Common research areas include MC3R/MC4R functional assays and near-analog comparisons.
- Of interest in studies that contrast free-acid versus amide-terminated cyclic scaffolds.
What is PT-141 (bremelanotide) in research?
PT-141 refers to bremelanotide, a cyclic heptapeptide melanocortin receptor agonist closely related to Melanotan II but terminating as a free acid rather than a C-terminal amide. That structural difference is useful when laboratories need to compare MC-receptor potency, selectivity, and peptide handling across near-analog scaffolds on the research bench.
Sequence shorthand is Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH. Supplied only for qualified research protocols. Keep amide-versus-acid identity clear whenever Melanotan II is run as a comparator standard, and archive chromatograms with each lot number used.
Typical laboratory applications
Common uses include MC3R/MC4R functional assays, side-by-side ranking versus Melanotan II, and analytical method checks (HPLC retention, MS identity) for cyclic melanocortin peptides. Investigators also document light and moisture sensitivity of lyophilized aliquots during storage validation on the research bench.
Note the free-acid terminus when comparing mass spectra or chromatographic retention to amide-terminated Melanotan II reference standards in the same assay batch.
