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). It also less potently inhibits other hexosaminidases and exochitinases. (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.
Chemische Eigenschaften
White to Off-White Solid
Verwenden
An inhibitor of O-GlcNAcase, hexosaminidase A, and hexosaminidase B
Biologische Aktivit?t
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.
