Sequence
dNal-Cys-Tyr-D-Trp-Lys-Val-Cys-Thr-NH2 (Cys2–Cys7 disulfide)
XCYWKVCT
Length counts residues; formula and mass are the stored free-base values from cited sources; CAS and PubChem identify the substance in public registries. More detail: length & peptide bonds, molecular weight
Structure & modifications
X in the 1-letter field stands for D-2-naphthylalanine, which is not a canonical residue.
Notes
Lanreotide (BIM-23014) is a disulfide-cyclized somatostatin octapeptide related to octreotide but different at both termini.
| Octreotide | Lanreotide | |
|---|---|---|
| Position 1 | D-Phe | D-2-Nal (X in 1-letter) |
| C-terminus | Threoninol | Thr-NH2 |
| Disulfide | Cys2–Cys7 | Cys2–Cys7 |
| CAS | 83150-76-9 | 108736-35-2 |
Display notation is mandatory because naphthylalanine is non-canonical. Modification tags include disulfide, D-amino acid, C-terminal amidation, and unusual amino acid.
Acetate salts are common in products and may carry different registry numbers than the free base listed here (PubChem CID 6918013).
