Opiorphin
Opiorphin is an endogenous 5-residue opioid peptide (Gln-Arg-Phe-Ser-Arg) first isolated from human saliva. Initial research with mice shows the compound has a painkilling effect greater than that of morphine. It works by stopping the normal breakdown of enkephalins, natural pain-killing opioids in the spinal cord. Opiorphin originates from the N-terminal region of the protein PROL1 (proline rich, lacrimal 1) and inhibits three proteases: neutral ecto-endopeptidase (MME), ecto-aminopeptidase N (ANPEP) and a dipeptidyl peptidase DPP3. This protease inhibitory action extends the duration of enkephalins, which are natural pain killers that are released in response to specific potentially painful stimuli. 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[1][2].
