  • Publication number: 20070258986
    Abstract: In accordance with the present invention, compounds, compositions and methods are provided that allow for the administration of a bioactive agent to an organism, including a human or an animal. The present invention can be used to treat or prevent a disease and/or disorder with a bioactive agent, or can be used to safely vaccinate a human or animal against a bioactive agent. The invention can also be used as a method for the delivery of bioactive agents for the treatment or prevention of a disease and/or a disorder, particularly targeted delivery of bioactive agents through the administration of glycoconjugates containing a bioactive agent bound to a targeting compound through a modified saccharide residue.
