General description

4-Nitrophenyl N-acetyl-β-D-galactosaminide is a chromogenic substrate for enzymes N-acetyl-β-D-galactosaminidase and N-Acetyl-β-D-hexosaminidase. It is membrane-permeable and serves as a substrate for the enzyme 6-sulfotransferase in Golgi vesicles.

Application

4-Nitrophenyl N-acetyl-β-D-galactosaminide has been used:
  • as a synthetic substrate in the glycosyl hydrolase assay of Yersinia pseudotuberculosis protein
  • as a substrate in -β-hexosaminidase assay in adenocarcinomic human alveolar basal epithelial cells A549
  • as a substrate for N-acetyl-β-D-galactosaminidase assay in rat kidney tissue extracts

The syntheses of 4-nitrophenyl beta-glycosides of the 3-thio and 4-thio analogues of the two principal 2-acetamido-2-deoxy-hexoses found in living systems, GlcNAc and GalNAc, are described. While synthesis of the 4-thio analogues could be achieved via nucleophilic displacements of sulfonate derivatives
