Description_x000D_ Application_x000D_ 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._x000D_ PUGNAc has been used as an inhibitor of O-GlcNAc-β-N-acetylglucosaminidase._x000D_ Biochem/physiol Actions_x000D_ 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)._x000D_ PUGNAc is an in vitro and in vivo inhibitor of peptide O-GlcNAc-β-N-acetylglucosaminidase, the enzyme which removes O-linked N-acetylglucosamine (O-GlcNAc) from O-linked glycosylated proteins.
