Patent number: 9346855Abstract: Described herein are modifications and adaptations of iron storage proteins for a novel photo-initiated approach to cancer therapy whereby cells are killed via production of iron-generated hydroxyl radicals. The iron is photo-released from a protein scaffold that includes tumor-targeting peptides and/or proteins fused to the exterior surface of the protein scaffold. One or more photosensitizers are coupled to the protein shell. The multiple tumor-targeting peptides and/or proteins will bind to specific hyperexpressed receptors on the cancer cells. After binding of the photosensitizer-iron-loaded protein to the cancer cells, photochemical excitation of the photosensitizers with tissue-penetrating near-infrared light triggers release of “free” ferrous iron, which in oxic or mildly hypoxic intracellular environments generates toxic hydroxyl radicals via Fenton chemistry. This light-triggered release of “free” iron overwhelms the cancer cells' defenses against free radicals.Type: GrantFiled: September 25, 2012Date of Patent: May 24, 2016Assignee: Board of Regents of the University of Texas SystemInventor: Donald M.

Patent number: 8623322Abstract: The present invention is directed to novel non-invasive diagnostic tools to diagnose numerous infectious disease states or conditions. The present invention represents a clear advance in the art which presently relies on tissue biopsy for diagnoses of these disease states. The novel imaging probe is capable of detecting infected cells, as well tissue. This represents a quantum step forward in the diagnosis and staging of NHL using non-invasively molecular imaging techniques. This novel probe will also be useful to monitor patients response to therapeutic treatments and other interventions or therapies used in the treatment of these disease states or conditions. Compounds according to the present invention may be used as diagnostic tools for a number of conditions and diseases states as well as therapeutic agents for treating such conditions and disease states. Pharmaceutical compositions are also described.Type: GrantFiled: June 15, 2009Date of Patent: January 7, 2014Assignee: STC.UNMInventor: Jeffrey P. Norenberg

Patent number: 8613904Abstract: The present disclosure concerns methods of administering and detecting a distinguishable agent in a sample from and assessing the condition of an organ in a subject. In a particular embodiment, the present invention concerns methods of detecting and comparing the cholate shunt, in a subject, preferably in a subject with chronic hepatitis C. In certain embodiments, the methods may comprise obtaining a sample from a subject such as a blood or saliva sample after administering an oral and intravenous dose of a distinguishable agent such as cholate and analyzing the sample clearance of the distinguishable agent from the subject and comparing the clearance levels in order to assess hepatic health. In another embodiment, the methods may comprise analyzing a sample from a subject for the presence of a distinguishable agent such as cholate and applying information obtained from analyzing the presence of the distinguishable agent to determine a treatment for a medical condition of the subject.Type: GrantFiled: January 26, 2006Date of Patent: December 24, 2013Assignee: The Regents of the University of ColoradoInventors: Gregory Thomas Everson, Michael Anthony Martucci

Publication number: 20130302243Abstract: Disclosed are novel, targeted, self-assembled nanoparticles radiolabeled with technetium-99m (Tc-99m) as radiodiagnostic compositions, methods of using these compositions and methods for preparing such radiolabeled compositions. Specifically, the compositions of the nanoparticles are composed of self-assembled polyelectrolyte biopolymers having targeting moieties, which can be suitable for targeted delivery of radionuclide metal ions complexed to the nanoparticles. These radiolabeled nanoparticles can specifically bind and internalize into the targeted tumor cells to realize the receptor mediated uptake. Radiolabeled, targeted nanoparticulate composition, methods for making, radiolabeling and using such compositions in the field of diagnosis and therapy are also provided.Type: ApplicationFiled: May 7, 2013Publication date: November 14, 2013Applicant: BBS NanoMedicina Zrt.Inventors: János Borbély, Magdolna Bodnár, Lajos Balogh, András Polyák
