We find that short OGA, which possesses O-GlcNAcase catalysis machinery like that of long OGA, exhibits comparative resistance to previously described potent inhibitors of long OGA and lysosomal hexosaminidases, including PUGNAc and NAG-thiazoline, suggesting a role for the HAT domain in O-GlcNAcase catalysis. These findings should aid the advancement of OGA inhibitors within the clinic. Oxid Med Cell Longev. Would you like email updates of new search results? Our study supports OGA inhibition being a feasible therapeutic strategy for hindering the progression of AD and other neurodegenerative diseases. When applied at nanomolar concentrations on live cells, these cell-penetrant molecules shift the Orally active. Irregular O‐GlcNAcylation is linked to several diseases including cancer, diabetes and neurodegeneration. ABSTRACT: Inhibition of O-GlcNAcase (OGA) has emerged as a promising therapeutic approach to treat tau pathology in neurodegenerative diseases such as Alzheimer’s disease and progressive supranuclear palsy. Shows antitauopathic effects in vivo. This enzyme catalyses the removal of the O-GlcNAc post-translational modification in the following chemical reaction: -3-O--L-serine + H2O ⇌ -L-serine + N-acetyl-D-glucosamine -3-O--L-threonine + H2O ⇌ -L-threonine + N-acetyl-D-glucosamine Kuang H, Tan CY, Tian HZ, Liu LH, Yang MW, Hong FF, Yang SL.

In vitro, this compound is a potent inhibitor of the human OGA enzyme with comparable activity against the corresponding … 2012;7(4):e35277. 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).  |  These data have stimulated interest in the possibility of using OGA-selective inhibitors as pharmaceuticals to alter the progression of AD. We focus on the catalytic mechanism and substrate recognition by OGA. 2 Protects cardiac function after trauma-hemorrhage which is mediated by increased protein O-GlcNAc levels. USA.gov. 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. The mechanisms mediating the neuroprotective effects of OGA inhibitors, however, remain poorly understood. The reagent su 2020 Oct 19;21(20):7739. doi: 10.3390/ijms21207739. O-GlcNAcylation is an essential posttranslational modification in metazoa. 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. Inhibition of O-GlcNAcase leads to elevation of O-GlcNAc tau and reduction of tauopathy and cerebrospinal fluid tau in rTg4510 mice. These compounds exhibited low micromolar affinity for OGT and inhibited O-GlcNAcylation of peptides and protein substrates in vitro (IC 50 =18 μM for goblin1) [ 44 ]. van Aalten*†2 *Medical Research Council Protein Phosphorylation and Ubiquitylation Unit, College of Life Sciences, University of Dundee, Dundee DD1 5EH, U.K. O-GlcNAcylation is a post-translational modification consisting of the addition of a single N-acetyl-glucosamine residue (GlcNAc) to specific serine/threonine residues of proteins.The addition of GlcNAc has been compared to phosphorylation, and there may be significant interplay between the two … European Journal of Pharmaceutical Sciences.

This review highlights recent insights into the structure of human O‐GlcNAcase and its isoforms. Modulation of O-GlcNAc levels with small molecule inhibitors of O-GlcNAc hydrolase (OGA) is a useful strategy to probe the role of this modification in a range of cellular processes. This effect correlates with increased nucleocytoplasmic levels of O ‐linked N ‐acetylglucosamine ( O ‐GlcNAc)‐modified proteins, and genetic knockdown of OGA expression closely phenocopies both these effects. 2020 Feb;26(2):155-166. doi: 10.1111/cns.13216.
