The invention is directed to pharmaceutical compositions and methods for delivery of a therapeutic or diagnostic agent from one bodily compartment to one or more other bodily compartment by administering one of the following conjugates: a polymer having multiple functional groups at least one of which is covalently bound to a therapeutic or diagnostic agent, and at least one cell uptake promoter covalently bound to the therapeutic or diagnostic agent; or a polymer and at least one cell uptake promoter bound thereto; the polymer further comprising multiple functional groups at least one of which is covalently bound a therapeutic or diagnostic agent.

Enhanced oral and transcompartmental delivery of therapeutic or diagnostic agents

A carrier for in vivo delivery of a therapeutic agent comprising a thiol group is provided, wherein the therapeutic agent is conjugated to the carrier via a biodegradable disulfide bond. Since extracellular fluids in vivo do not provide the appropriate environment to efficiently reduce a disulfide bond, while cellular cytosol does provide an appropriate environment, the agent will remain substantially coupled to the carrier while circulating through the body until the carrier crosses a cell membrane. As a result, the therapeutic agent is protected from degradation and renal clearance, and the potential for the therapeutic agent to elicit an immune response is limited.
