132489-69-1 Usage
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). 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.

Uses
Different sources of media describe the Uses of 132489-69-1 differently. You can refer to the following data:
1. An inhibitor of O-GlcNAcase, hexosaminidase A, and hexosaminidase B
2. 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.
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.
