ABSTRACT:
Disclosed are compounds that exhibit high transport across the intestinal wall of an animal. The compounds may optionally be linked to drugs that are poorly absorbed or poorly transported across the intestinal wall after oral administration to provide for enhanced therapeutic, and optionally prolonged therapeutic, systemic blood concentrations of the drugs upon oral administration of the drug-compound conjugate. Also disclosed are pharmaceutical compositions containing and methods of using such compounds.
