产品描述

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]
