Galactosamines

Benzyl-α-GalNAc is a potent O-glycosylation inhibitor. Benzyl-α-GalNAc effectively inhibits the proliferation and activation of LX-2 cells and suppresses the expression of collagen I/III, which has good potential for investigation in liver fibrosis. Benzyl-α-GalNAc also significantly enhances the anti-tumour activity of 5-Fluorouracil (HY-90006) (e.g. pancreatic cancer) by inhibiting O-glycosylation.

β-D-Galactosamine pentaacetate is an intermediate in the synthesis of triantennary N-Acetylgalactosamine ligands. β-D-Galactosamine pentaacetate can be studied in liver-targeted delivery of siRNA research.

AZP-531 is an analogue of unacylated ghrelin designed to improve glycaemic control and reduce weight.

4-Nitrophenyl-N-acetyl-β-D-galactosaminide has inhibitory activity against GlcNAc and GalNAc with K_is of 1.15 mM and 0.51 mM, respectively. 4-Nitrophenyl-N-acetyl-β-D-galactosaminide is extracted from Trichomonas foetus (T. foetus)

4-Methylumbelliferyl-N-acetyl-β-D-galactosaminide is a substrate for detecting β-galactosidase activity.
