prolyl endopeptidase (prep)

Salidroside is a bioactive phenolic glycoside compound isolated from Rhodiola rosea and is a prolyl endopeptidase inhibitor. Salidroside can alleviate cachexia symptoms in a tumor cachexia mouse model by activating mTOR signaling and protect dopaminergic neurons by enhancing PINK1/Parkin-mediated mitochondrial autophagy. Salidroside can also inhibit the growth of cancer cells by regulating the CDK4-cyclin D1 pathway to block the G1 phase and/or regulating the Cdc2-cyclin B1 pathway to block the G2 phase.

β-Elemonic Acid (3-Oxotirucallenoic Acid) exhibits anti-inflammatory effects. Beta-Elemonic acid inhibits proliferation by inducing hypoploid cells and cell apoptosis, the anticancer effects of beta-Elemonic acid are related to the MAPK signaling pathway, ROS activation and glutathione depletion in human A549 lung cancer cells. Beta-Elemonic acid exhibits prolyl endopeptidase inhibitory activities.

Oroxylin A 7-O-β-d-glucuronide and wogonoside should also be served as the chemical markers together with baicalin for the quality control of herbs and proprietary traditional Chinese medicine (PTCM) products of radix Scutellariae. Oroxylin A 7-O-glucuronide, Oroxin A, and Oroxin B can bind to the "stem" region of α-hemolysin (α-HL), when inhibiting the hemolytic activity of α-HL. Oroxylin A 7-O-glucuronide and 4', 5, 7-trihydroxy-6-methoxyflavone at a concentration of 100 microM inhibit 34 and 43% of total prolyl oligopeptidase (POP) activity, respectively.

KYP-2047 is a very potent, selective Prolyl oligopeptidase (POP) inhibitor.

BR102910 (4-Thiazolecarboxamide, N-[2-[(2S)-2-cyano-4,4-difluoro-1-pyrrolidinyl]-2-oxoethyl]-2-[(3,4-dichlorophenyl)methyl]-) is a selective inhibitor of fibroblast activated protein (FAP).

Linderene acetate is a competitive inhibitor against Prolyl endopeptidase.

Picromycin is a 14-membered macrolide antibiotic and Prolyl endopeptidase (PREP) inhibitor. Pikromycin shows activity against gram-positive bacteria including mycobacteria.

Y-29794 Tosylate (Y-29794) is an orally active, effective, and specific non-peptide-prolyl endopeptidase (PPCE) inhibitor.

Z-Pro-prolinal (N-Benzyloxycarbonyl-L-prolyl-L-prolinal) is a specific and orally active inhibitor of prolyl endopeptidase (PREP) with an IC50 of 0.4 nM against porcine PREP [1] [2] [3].

Z-Pro-Pro-CHO acts as a prolyl oligopeptidase inhibitor with half-maximal inhibitory concentrations (IC50) of 0.16 μM for human prolyl oligopeptidase and 0.01 μM for Schistosoma mansoni prolyl oligopeptidase [1].

Z-Pro-Pro-aldehyde-dimethyl acetal is a potent prolyl endopeptidase (PREP) inhibitor, effectively impeding the activity of this cytoplasmic serine endoprotease with an IC50 of 12 nM. Its significance lies in its role in modulating cognitive dysfunction associated with aging and neurodegenerative conditions, such as Alzheimer's disease [1] [2].

DOTA.SA.FAPi TFA is a bifunctional chelator composed of squaric acid (squaric acid) and UAMC1110, integrating the properties of DATA5m and DOTA. It exhibits inhibitory activity against fibroblast activation protein (FAP) with an IC50 of 0.9 nM and targets the prolyl endopeptidase (PREP) with an IC50 of 5.4 μM. After labeling with 68Ga, DOTA.SA.FAPi TFA serves as a PET tracer for cancer research.
