Y-29794 tosylate

Description

Y-29794 Tosylate is an orally active, potent and specific non-peptide prolyl endopeptidase (PPCE) inhibitor. Y-29794 selectively and competitively inhibited rat brain PPCE (Ki = 0.95 nM) in a reversible manner. Ex vivo study demonstrated that Y-29794 could penetrate into brain to exhibit dose-dependent and long-lasting inhibition. Furthermore, Y-29794 could potentiate the effect of TRH on the release of ACh in the rat hippocampus. Y-29794 prevents the progression of A beta-like deposition in the hippocampus of the SAM.

Uses

Y-29794 tosylate is a selective, orally active inhibitor for non-peptide prolyl endopeptidase (PREP), with an IC50 of 3 nM and a Ki of 0.95 nM. Y-29794 tosylate enhances the effect of thyrotropin-releasing hormone (TRH) on the release of ACh in the rat hippocampus, exhibits potential neuroprotective efficacy. Y-29794 tosylate exhibits anticancer activity through inhibition of the IRS1-AKT-mTORC1 pathway. Y-29794 tosylate penetrates the brain-blood barrier (BBB)[1][2].
