- Peptide
- Scientific name
- Bremelanotide — N-acetyl-L-norleucyl-L-alpha-aspartyl-L-histidyl-D-phenylalanyl-L-arginyl-L-tryptophyl-L-lysine (2→7)-lactam
- Amino acids
- 7
- Sequence
- Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH
- Molecular weight
- 1025.2 g/mol
- Formula
- C50H68N14O10
- CAS
- 189691-06-3
- Origin
- Synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (alpha-MSH); not gene-encoded — N-acetylated, built with norleucine and D-phenylalanine and closed by an Asp2→Lys7 side-chain lactam bridge.
- Lyophilized (powder)
- -20°C · stable long-term; protect from light and moisture
- Reconstituted
- 2-8°C · use within ~30 days; avoid repeated freeze-thaw cycles
- Room temperature
- Lyophilized powder tolerates brief ambient exposure during shipping and handling, but sustained storage above 2-8°C once reconstituted promotes hydrolysis and aggregation of the peptide. No compound-specific stability study for PT-141 was located in the fetched literature; the guidance above is standard handling for a lyophilized synthetic peptide, not a literature-derived specification.
