Abstract
A bifunctional compound with a monosaccharide and a NSligand, and more particularly, a bifunctional compound with a NSligand and aminohexylacetyl galactosamine (ah-GalNAc) is provided. A method for preparing the bifunctional compound with a monosaccharide and a NSligand is also provided, including activating a carboxyl group in an organic ligand, reacting the activated carboxyl group with a galactopyranoside through amidation, and then hydrolyzing. The bifunctional compound of the present invention is widely useful in nuclear medicine for preparation of liver imaging agents for assisting in correct diagnosis of diseases.
