Opiorphin
Based on 1 Customer Validation
Opiorphin, an opioid peptide, is a potent enkephalin-inactivating zinc ectopeptidases in human inhibitor. Opiorphin inhibits two enkephalin-catabolizing ectoenzymes, human neutral ecto-endopeptidase, hNEP (EC 3.4.24.11) with an IC50 value of 11 μM, and human ecto-aminopeptidase, hAP-N (EC 3.4.11.2). Opiorphin displays potent analgesic activity by activating endogenous opioid-dependent transmission.

Biological Activity
Opiorphin (1-100 μM; the mouse isolated colon) causes contractile effects in mouse distal colon in a concentration-dependent manner and enhances the contractile response induced by Met-enkephalin[1].
Opiorphin (0-50 μM; hNEP or hAP-N transformed HEK293 cell line) is a dual inhibitor of enkephalin-degrading hNEP and hAP-N in vitro. Opiorphin inhibits Mca-BK2 endoproteolysis by the cell-surface recombinant hNEP with an IC50 value of 33 μM. and inhibits the Ala-pNA cleavage by hAP-N with an IC50 value of 65 μM[2].
