Patent number: 11813375Abstract: A novel therapeutic agent for solid cancer capable of hardening the cellular tissue itself of a solid cancer to induce death or growth inhibition of cancer cells, causing solidification of the tissue, is disclosed. The therapeutic agent for solid cancer is composed of a liquid composition containing as an active component an ethoxy-containing compound capable of undergoing polycondensation in a cellular tissue. The therapeutic agent for solid cancer is capable of hardening the cellular tissue itself of a solid cancer such as lung cancer to induce death or growth inhibition of cancer cells, causing solidification of the tissue. In conventional therapeutic methods, the risk of metastasis due to spreading of cancer cells through the bloodstream cannot be eliminated. In contrast, this therapeutic agent for solid cancer instantly surrounds cancer cells, so that the risk of metastasis can be largely reduced.Type: GrantFiled: July 7, 2017Date of Patent: November 14, 2023Assignee: YANCHERS INC.Inventor: Junichi Shimada

Patent number: 7976825Abstract: Macromolecular contrast agents for magnetic resonance imaging are described. Biomolecules and their modified derivatives form stable complexes with paramagnetic ions thus increasing the molecular relaxivity of carriers. The synthesis of biomolecular based nanodevices for targeted delivery of MRI contrast agents are described. Nanoparticles (NP) have been constructed by self-assembling of chitosan (CHIT) as polycation and poly-gamma glutamic acids (PGA) as polyanion. NP's are capable of Gd-ion uptake forming a particle with suitable molecular relaxivity. Folic acid (FA) is linked to the NP's to produce NP-FA bioconjugates that can be used for targeted in vitro delivery to a human cancer cell line.Type: GrantFiled: December 8, 2008Date of Patent: July 12, 2011Inventors: Janos Borbely, Magdolna Bodnar, John F Hartmann, Istvan Hajdu, Jozsef Kollar, Gyorgy Vamosi

Publication number: 20110123457Abstract: A therapeutic agent formed of a magnetic resonance imaging tracer conjugated with a chemotherapeutic agent. The therapeutic agents can be used in measuring drug delivery to a target tissue. The therapeutic agents allow for therapeutic MRI, in which 19F MRI techniques are used to detect, monitor, evaluate, and/or adjust chemotherapeutic drug dosage levels in a patient or a targeted tissue thereof.Type: ApplicationFiled: December 17, 2010Publication date: May 26, 2011Inventor: Yihua Yu
