Latest Patents

One of Yong-Kyu Lee's latest patents involves the oral delivery of macromolecules, specifically polysaccharides like heparin. Traditionally, these anticoagulation drugs are administered through intravenous or subcutaneous injections due to their hydrophilicity and high negative charge. Lee's innovative approach includes synthesizing amphiphilic heparin derivatives by conjugating them with bile acids, sterols, and alkanoic acids. These derivatives exhibit improved solubility in water and maintain high anticoagulation activity, allowing for efficient absorption in the gastrointestinal tract.

Another notable patent focuses on the formulation of amphiphilic heparin derivatives to enhance mucosal absorption. This involves creating a powdered heparin composition by dissolving the amphiphilic derivative in a water phase, forming an emulsion, and subsequently drying it. Additionally, he has developed methods for creating heparin-containing nanoparticles that incorporate surfactant molecules, further enhancing the delivery of these important drugs.
