Design and Synthesis of Pro-Drugs for Selective, Oral Delivery to the Gastrointestinal Tract
This invention provides a method for oral administration and targeted delivery of pro-drugs bonded to a carbohydrate-based molecular scaffold to the gastrointestinal tract, where the pro-drug is released directly in the gastrointestinal (GI) tract by nitroreductase enzymes naturally present. This technology provides a means of delivery of GI therapies...

A Molecular Scaffold for Colonic Drug Delivery
A molecule which passes through the gastrointestinal tract was successfully synthesized and tested for GI MRI imaging in mice. A molecular scaffold bearing eight terminal alkyne groups was synthesized from sucrose, and copies of an azide-terminated Gd-DOTA complex were attached via copper(I)-catalyzed azide-alkyne cycloaddition. This contrast agent...

A GI-Specific Contrast Agent for Magnetic Resonance Imaging
A scaffold bearing eight terminal alkyne groups was synthesized from sucrose, and copies of an azide-terminated Gd-DOTA complex were attached via copper(I)-catalyzed azide-alkyne cycloaddition in this invention. This contrast agent (CA) was administered by gavage to C3H mice. Passage of the CA through the gastrointestinal (GI) tract was followed by...

Targeted Drug Delivery in the Gastrointestinal Tract, including for Inflammatory Bowel Disease
This invention is a scaffold molecule and a method for using the molecule to deliver active drug molecules to targets in the body. The sucrose-derived scaffold molecule delivers the drug to target sites and releases the drug molecules based on environmental factors, which improves efficacy and reduces side effects.
Background:
Throughout their research,...
