Title: Innovations by Annie Yau-Young in Liposome Technology
Introduction
Annie Yau-Young is a prominent inventor based in Los Altos, California, known for her significant contributions to the field of liposome technology. With a total of six patents to her name, she has developed innovative methods and compositions that enhance the delivery of therapeutic compounds in medical treatments.
Latest Patents
Among her latest patents is the "Microreservoir liposome composition and method." This invention focuses on a liposome composition designed for the extended release of therapeutic compounds into the bloodstream. The liposomes are formulated with vesicle-forming lipids and a specific percentage of a lipid derivatized with a hydrophilic polymer. They are engineered to have sizes ranging from 0.1 to 0.4 microns and contain the therapeutic compound in an entrapped form. This composition allows for a dosage that is three times the amount required for intravenous injection in free form. Additionally, the method disclosed extends the therapeutic activity of the compound in the bloodstream for at least 24 hours.
Another notable patent is the "Solid tumor treatment method and composition." This invention provides a liposome composition that localizes an anti-tumor compound to a solid tumor via the bloodstream. The liposomes, which encapsulate the anti-tumor agent, are composed of vesicle-forming lipids and a biocompatible polymer. They are designed to be taken up by the tumor within 24 to 48 hours after intravenous administration, allowing for site-specific release of the entrapped compound. This method has shown promising results in regressing solid colon and breast carcinomas that are resistant to conventional treatments.
