Description
O-[2-ACETAMIDO-2-DEOXY-D-GLUCOPYRANOSYLI], also known as PUGNAc, is a (phenylcarbamoyl)oxime analog of N-acetylglucosamine (GlcNAc) that plays a crucial role in the post-translational modification of proteins. It is a white to off-white solid and acts as a reversible inhibitor of nuclear cytoplasmic O-GlcNAcase and acetyltransferase (NCOAT), a β-N-acetylglucosaminidase that removes GlcNAc from O-glycosylated proteins. PUGNAc also inhibits other hexosaminidases and exochitinases, albeit with less potency.

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).

Check Digit Verification of cas no
The CAS Registry Mumber 132489-69-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,8 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 132489-69:
(8*1)+(7*3)+(6*2)+(5*4)+(4*8)+(3*9)+(2*6)+(1*9)=141
141 % 10 = 1
So 132489-69-1 is a valid CAS Registry Number.
