p-Nitrophenyl 2-Acetamido-3,4,6-tri-O-acetyl-β-D-glucopyranoside (CAS 13089-27-5)

p-Nitrophenyl 2-Acetamido-3,4,6-tri-O-acetyl-β-D-glucopyranoside is a chemically synthesized glycoside used extensively in the study of enzymatic activities, particularly those of glycosidases and glycosyltransferases involved in carbohydrate metabolism. The compound features a p-nitrophenyl moiety linked to a β-D-glucopyranoside structure, which is further modified by acetylation at the 3, 4, and 6 positions and an acetamido group at the 2 position. This glycoside serves as a substrate in enzyme assays where the cleavage of the glycosidic bond by specific enzymes releases p-nitrophenol, a compound that can be easily detected spectrophotometrically due to its yellow coloration upon ionization in alkaline conditions. This characteristic makes it particularly useful for quantifying enzyme kinetics and determining substrate specificity, facilitating detailed studies on the catalytic mechanisms of enzymes that modify or degrade glycosidic bonds. In research, this compound is invaluable for probing the action of N-acetyl-β-D-glucosaminidases, enzymes critical in the processing of glycoproteins and glycolipids in cells. Understanding these enzymes helps explain fundamental biological processes such as cell signaling, pathogen interaction, and cellular waste management, contributing significantly to the fields of biochemistry and molecular biology. This glycoside′s use is strictly confined to research applications, providing insights into enzyme behavior and assisting in the development of inhibitors that could be used to regulate these crucial biological processes.
