In addition, it presents an updated overview of small‐molecule OGA inhibitors, with either carbohydrate or noncarbohydrate scaffolds. For the biopharma industry investment, business development and competitive intelligence professionals who require information to support financing, partnering and licensing activities, BCIQ provides accurate information and context to support profitable and strategic decision making. Novel non-carbohydrate O-GlcNAcase inhibitors with CNS drug properties as potential treatment for Alzheimer’s disease and tauopathies. Inhibition of O-GlcNAcase (OGA), the enzyme responsible for the removal of O-GlcNAc modification, has been shown to reduce tau pathology in several transgenic models. In order to identify new human O‐GlcNAcase inhibitors, a high‐throughput screening assay was performed based on the release of 4‐methylumbelliferol (4MU) from the pseudo substrate 4MU‐GlcNAc, initially using the bacterial OGA homologue from C. perfringens (CpOGA) which has recently been shown to be a good model of hOGA . Moreover, there are a number of mechanistically similar related enzymes such as β‐hexosaminidases (Hex), and the concomitant inhibition of these enzymes leads to undesirable lysosomal‐storage disorders.

Hastings NB, Wang X, Song L, Butts BD, Grotz D, Hargreaves R, Fred Hess J, Hong KK, Huang CR, Hyde L, Laverty M, Lee J, Levitan D, Lu SX, Maguire M, Mahadomrongkul V, McEachern EJ, Ouyang X, Rosahl TW, Selnick H, Stanton M, Terracina G, Vocadlo DJ, Wang G, Duffy JL, Parker EM, Zhang L. Mol Neurodegener. Screening-based discovery of drug-like O-GlcNAcase inhibitor scaffolds Helge C. Dorfmueller, Daan M.F. Recently, the discovery of small‐molecule OGA inhibitors has enabled the physiological function of O‐GlcNAcylation … A widely used tool for increasing cellular levels of O-GlcNAc. van Aalten* Division of Molecular Microbiology, College of Life Sciences, University of Dundee, Dundee DD1 5EH, Scotland, UK article info Article history: Received 16 October 2009 Revised 1 December 2009 Accepted 13 December 2009 Available online 16 December 2009 Edited by Judit … This protein modification is mainly governed by a pair of enzymes: O‐GlcNAc transferase (OGT) adds the N‐acetylglucosamine moiety to acceptor proteins, and O‐GlcNAcase (OGA) hydrolyses the sugar moiety from protein acceptors. NIH Pharmacological inhibition of O-GlcNAcase (OGA), the sole enzyme that removes O-GlcNAc, reproducibly slows neurodegeneration in various Alzheimer's disease (AD) mouse models manifesting either tau or amyloid pathology. Chemical structure. Please check your email for instructions on resetting your password. Here we described the in vitro and in vivo pharmacological properties of a novel and selective OGA inhibitor, MK-8719. When applied at nanomolar concentrations on live cells, these cell-penetrant molecules shift the Alzheimer’s disease; O-GlcNAc; Thiamet-G; autophagy; glycosylation; neurodegeneration. Irregular O‐GlcNAcylation is linked to several diseases including cancer, diabetes and neurodegeneration. Inhibition of O-GlcNAcase leads to elevation of O-GlcNAc tau and reduction of tauopathy and cerebrospinal fluid tau in rTg4510 mice. Beginning with carbohydrate-based lead molecules, we pursued an optimization strategy of reducing polar surface area to align the desired drug-like properties of potency, selectivity, high … Differential effects of an O-GlcNAcase inhibitor on tau phosphorylation. Sci Rep. 2019 May 13;9(1):7287. doi: 10.1038/s41598-019-43017-9. The glycosylation of nucleocytoplasmic proteins with O-linked N-acetylglucosamine residues (O-GlcNAc) is conserved among metazoans and is particularly abundant within brain. These data have stimulated interest in the possibility of using OGA-selective inhibitors as pharmaceuticals to alter the progression of AD. PUGNAc (CAS 132489-69-1) is an O-GlcNAcase (O-GlcNAc-β-N-acetylglucosaminidase) and β-hexosaminidase inhibitor (K i =46 and 36 nM, respectively).
