| Hazard Information | Back Directory | [Description]
Proteins can be modified post-translationally by the addition of O-linked N-acetylglucosamine (O-GlcNAc). Nuclear cytoplasmic O-GlcNAcase and acetyltransferase (NCOAT) is a β-N-acetylglucosaminidase that removes GlcNAc from O-glycosylated proteins. PUGNAc is a (phenylcarbamoyl)oxime analog of GlcNAc that reversibly inhibits NCOAT (Ki = 40-110 nM).1,2 It also less potently inhibits other hexosaminidases and exochitinases.2,3,4 (Z)-PUGNAc is a stereoisomer of PUGNAc that is a more potent inhibitor of NCOAT than the (E) isomer, both in vitro and in cells.5 | [Chemical Properties]
White to Off-White Solid | [Uses]
O-(2-acetamido-2deoxy-D-glucopyranosylidene)amino-N-phenylcarbamate (PUGNAc) has been used to evaluate the effects of silibinin on O-GlcNAc levels of glycoproteins in Adult Retinal Pigment Epithelial-19 (ARPE-19) cells. It has also been used as a component of the HEPES lysis buffer for rat brain samples. | [Uses]
An inhibitor of O-GlcNAcase, hexosaminidase A, and hexosaminidase B | [Biological Activity]
O -GlcNAc- β - N -acetylglucosaminidase ( O -GlcNAcase) and β -hexosaminidase inhibitor (K i values are 46 and 36 nM respectively) that increases O -GlcNAc levels ~ 2-fold in HT29 cells. Z -linked isomer is more potent than the E isomer. | [Biochem/physiol Actions]
O-(2-acetamido-2deoxy-D-glucopyranosylidene)amino-N-phenylcarbamate (PUGNAc) induces insulin resistance in 3T3-L1 adipocytes by reducing insulin-prompting phosphorylation of protein kinase B (Akt) and glycogen synthase kinase 3β (GSK3β). | [storage]
