Prolyl Endopeptidase (PREP)

prolyl oligopeptidase; POP

Prolyl endopeptidase (PREP), also known as prolyl oligopeptidase (POP), a member of the serine protease family, which can specifically hydrolyze the peptide bond of the carboxylterminus of the proline residue in the polypeptide chain, has high activity in the liver. Accumulated evidence suggests that PREP participates in physiological and pathological processes, including maturation and degradation of peptides, inflammation, oxidative stress, autophagy, cell proliferation and cancer.

    RB 101
    		Inhibitor
    RB 101 is an active mixed inhibitor against two enzymes which metabolize the enkephalins neutral endopeptidase and aminopeptidase N. RB 101 has rather long-lasting antinociceptive effects. RB 101 inhibits the in vivo [3H]DPN binding both under basal conditions and after swim stress in mice. RB 101 can be used to determine the precise in vivo localization of enkephalinergic pathways recruited by various stimuli.

    ONO 1603
    		Inhibitor
    ONO 1603, a novel prolyl endopeptidase inhibitor investigated as a potential antidementia drug, demonstrated neuroprotective and neurotrophic effects in cerebellar granule cells similar to tetrahydroaminoacridine (THA). At a concentration of 0.03 microM, ONO 1603 promoted neuronal survival, enhanced neurite outgrowth, increased m3-muscarinic acetylcholine receptor (mAChR) mRNA levels, and stimulated mAChR-mediated signaling pathways. These findings suggest that ONO 1603 shares pharmacological similarities with THA, indicating its potential as a therapeutic agent for Alzheimer's disease by enhancing cholinergic neurotransmission and neuronal function.
