Application

KYP-2047 may be used in prolyl endopeptidase-mediated cell signaling studies.

Biochem/physiol Actions

KYP-2047 clears the α-synuclein aggregates induced by oxidative stress in the neuronal cells. α-synuclein is the main component of Lewy bodies in Parkinson′s disease that cause neuronal cell death and dementia.
KYP-2047 is a very potent, selective inhibitor of Prolyl oligopeptidase (POP), also known as prolyl endopeptidase (PEP or PE). Ki = .023nM (porcine). KYP-2047 has been found to be neuroprotective against glutamate and oxygen, glucose deprivation in vitro. It has also been used to inhibit the formation of AcSDKP from its precursor 43-mer thymosin β4 (Tβ4). Ac-SDKP is involved in hemopoietic stem cell differentiation, is pro-angiogenic and antifibrogenic.

Decreased clearance of α-synuclein (aSyn) and aSyn protein misfolding and aggregation are seen as major factors in the pathogenesis of Parkinson's disease (PD) and other synucleinopathies that leads to disruption in neuronal function and eventually to cell death. Prolyl oligopeptidase

Prolyl oligopeptidase (prolyl endopeptidase, Prep), a multifunctional protease hydrolyzing -Pro-X- peptide bonds, is highly expressed in the mouse placenta, but the function during development is not known. We explored the possibility of Prep's involvement in placental differentiation. We cultured trophoblast

Prolyl endopeptidase (PREP) is a serine endopeptidase widely distributed in the body, and accumulated evidence suggests that PREP participates in inflammation and oxidative stress. Here, we explored the effect of PREP gene disruption on hepatic inflammation and oxidative stress status

British journal of pharmacology, 166(3), 1097-1113 (2012-01-12)
The aggregation of α-synuclein is connected to the pathology of Parkinson's disease and prolyl oligopeptidase (PREP) accelerates the aggregation of α-synuclein in vitro. The aim of this study was to investigate the effects of a PREP inhibitor, KYP-2047, on α-synuclein
