Chemical compound

Leumorphin, also known asdynorphin B1–29, is anaturally occurringendogenous opioidpeptide.[1][2][3] Derived as aproteolyticcleavage product ofresidues 226-254 ofprodynorphin (preproenkephalin B),[4][5] leumorphin is a nonacosapeptide (29amino acids in length) and has thesequence Tyr-Gly-Gly-Phe-Leu-Arg-Arg-Gln-Phe-Lys-Val-Val-Thr-Arg-Ser-Gln-Glu-Asp-Pro-Asn-Ala-Tyr-Ser-Gly-Glu-Leu-Phe-Asp-Ala. It can be further reduced todynorphin B (dynorphin B-13) anddynorphin B-14 bypitrilysin metallopeptidase 1 (formerly referred to as "dynorphin-converting enzyme"), anenzyme of theendopeptidase family.[6][7][8] Leumorphin behaves as a potent and selectiveκ-opioid receptoragonist, similarly to other endogenous opioid peptide derivatives of prodynorphin.[9][10]
