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.

    HUP-55
    		Inhibitor
    HUP-55 is a prolyl endopeptidase inhibitor (IC50 = 5 nM). HUP-55 reduces the dimerization of α-synuclein in Neuro2a cells and induces autophagy (Autophagy) in HEK293 cells. It also decreases the increase in reactive oxygen species (ROS) production induced by hydrogen peroxide in SH-SY5Y cells at a concentration of 10 µM. In a mouse Parkinson’s disease model, HUP-55 (10 mg/kg) improves motor function (reduces the use frequency of the impaired paw) and decreases the levels of harmful oligomers of α-synuclein in the striatum caused by overexpression of α-synuclein.
