Abstract

Liver targeting of antiviral nucleoside analogs can be obtained by conjugating these drugs with the hepatotropic molecule lactosaminated serum albumin. We describe a new coupling procedure which uses the imidazolides of the phosphoric ester derivatives of the drugs in an alkaline medium. By this procedure conjugates are obtained with a high drug/carrier molar ratio and without the unwanted protein chemical changes produced by carbodiimides usually employed for this coupling.
