Application

Z-Pro-prolinal was used to inhibit activation of rekallikrein in Prolylcarboxypeptidase assay in HUVECs. ZPP was also used in assays to identify enzymes important in the processing of angiotensin peptides in human glomerular endothelial cells.

Biochem/physiol Actions

Z-Pro-prolinal is a potent, selective inhibitor of Prolyl oligopeptidase (POP), also known as prolyl endopeptidase (PEP or PE). Ki = 1 nM.

POP has been connected to memory and mood through regulation of the brain levels of its peptide substrates, which include AVP, substance P, neurotensin and TRH and is a potential target in cognitive function, memory, and neurodegenerative disorders such as amnesia, Alzheimer′s disease, and depression. POP has recently been reported to be involved in the release of the tetrapeptide acetyl-N-Ser-Asp-Lys-Pro (Ac-SDKP) from its precursor, 43-mer thymosin β4 (Tβ4). Ac-SDKP is involved in hemopoietic stem cell differentiation, is pro-angiogenic and antifibrogenic.

The intraglomerular renin-angiotensin system (RAS) is linked to the pathogenesis of progressive glomerular diseases. Glomerular podocytes and mesangial cells play distinct roles in the metabolism of angiotensin (ANG) peptides. However, our understanding of the RAS enzymatic capacity of glomerular endothelial

Angiotensin converting enzyme 2 (ACE2) is an enzyme that limits activity of the renin-angiotensin system (RAS) and also serves as a receptor for the SARS-CoV-2 Spike (S) protein. Binding of S protein to ACE2 causes internalization which activates local RAS.

The serine protease prolylcarboxypeptidase (PRCP), isolated from human umbilical vein endothelial cells (HUVECs), is a plasma prekallikrein (PK) activator. PRCP cDNA was cloned in pMT/BIP/V5-HIS-C, transfected into Schneider insect (S2) cells, and purified from serum-free media. Full-length recombinant PRCP (rPRCP)

Previous studies have shown that prolyl oligopeptidase (PREP) negatively regulates autophagy and increases the aggregation of alpha-synuclein (αSyn), linking it to the pathophysiology of Parkinson's disease. Our earlier results have revealed that the potent small molecular PREP inhibitor KYP-2047 is
