Abstract :
A series of novel aryl-substituted triazolyl d-galactosamine derivatives was synthesized as ligands for the carbohydrate recognition domain of the major subunit H1 (H1-CRD) of the human asialoglycoprotein receptor (ASGP-R). The compounds were biologically evaluated with a newly developed competitive binding assay, surface plasmon resonance and by a competitive NMR binding experiment. With compound 1b, a new ligand with a twofold improved affinity to the best so far known d-GalNAc was identified. This small, drug-like ligand can be used as targeting device for drug delivery to hepatocytes.
