  • Anti liver disease drug R-YEEE and method of synthesizing branched galactose-terminal glycoproteins
    Patent number: 6383812
    Abstract: The present invention provides a novel method of synthesizing branched galactose-terminal glycoproteins. A number of these glycoproteins have binding affinity to the asialoglycoprotein receptor. The present invention also provides novel conjugates having branched galactose-terminal glycoproteins that is complexed to a therapeutically effective agent, such as an isolated protein, polysacharides, lipids and radioactive isotope. These conjugates may be used to deliver the therapeutically effective agent to mammalian cells generally, and to hepatocytes specifically.
