Enhanced oral and transcompartmental delivery of therapeutic or diagnostic agents
First Claim
1. A method for delivery of a therapeutic or a diagnostic agent from an initial bodily compartment to at least one target bodily compartment, the method comprising administering to said initial bodily compartment an effective transcompartmental delivery promoting amount of:
- a) 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 said therapeutic or diagnostic agent;
or b) a polymer and at least one cell uptake promoter covalently bound thereto;
the polymer further comprising multiple functional groups at least one of which is covalently bound to a therapeutic or diagnostic agent.

Abstract
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.

47. Compounds of the general formulas:
(X)o-(Y)m-(linker)n (Y)m-(linker)n-(X)o where X is 1 or more transporter, receptor, binding or targeting ligands, including retro inverso peptides, which may be identical or non-identical;
where Y is 1 or more of any therapeutic or diagnostic moieties, naturally-occurring or artificial, including retro inverso peptides, which may be identical or non-identical;
where linker comprises polymer with functional groups and provides covalent bonds between linker and X and/or Y;
where transporter is a moiety for which a transporter protein therefore is present in epithelial cells of the intestine; and
m, n, and o may be any independently varying integers, or more specifically may each independently vary from 1 to about 100. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66)
