Publication number: 20250120947Abstract: The present invention generally relates to sensitizer compounds and their use to sensitize cancer and/or pre-cancerous cells of certain cancers to treatment with certain resistance-prone therapeutics used in cancer therapy. In embodiments, the conjugates of particular esters or amides of Near Infrared Dyes, are used as sensitizers to avoid or overcome therapeutic resistance once formed. In embodiments, the sensitizers include conjugates with Cisplatin, Simvastatin, Artemisinin, platin-based compounds or statins. In embodiments, the resistance prone cancer therapeutics include cisplatin, gemcitabine, doxorubicin, paclitaxel, docetaxel, and platin-based compounds. These may be administered in combination with the sensitizer, or the sensitizer itself may comprise an therapeutci-derived moiety conjugated to the sensitizer, for example as is the case for dye-CIS conjugated sensitizers. Alternatively, the sensitizer may be co-administered with one or more therapeutic.Type: ApplicationFiled: September 23, 2024Publication date: April 17, 2025Inventors: Liyuan Yin, Yi Zhang, Stefan Mrdenovic, Gina Chia Yi Chu, Ruoxiang Wang, Qinghua Zhou, Jian Zhang, Leland W.K.

Publication number: 20240307560Abstract: Embodiments of the present invention generally relate to conjugates of heptamethine carbocyanine dye (HMCD)-chelator radiometal complexes, radiopharmaceutical formulations comprising such complexes and their use, in particular for internal radiotherapy and/or imaging of cancer. In particular, in embodiments, provided are DZ-1-Lys-DOTA conjugates complexed with Lutetium-177, Yttrium-90 or Gallium-68, or combinations thereof. Some embodiments provide improved radiotherapy with complexes of Lutetium-177 or Yttrium-90. Further embodiments provide improved radioimaging with Gallium-68 complexes, and their use. Yet further embodiments provide improved image-guided therapy by using matched theranostic pairs of such conjugates, wherein for therapy purposes the radiometal is selected from one or more of Lutetium-177, Yttrium-90, each of which for imaging purposes may be paired with Gallium-68, for improved image-guided radiotherapy.Type: ApplicationFiled: December 30, 2021Publication date: September 19, 2024Inventors: Leland W.K.

Publication number: 20170314056Abstract: The present invention describes methods of identifying, detecting, imaging, isolating and locating cancer cells in a subject. The method involves the use of near-infrared (NIR) organic carbocyanine dyes, particularly, near infrared heptamethine cyanine dyes and the detection of the fluorescence of these NIR dyes. The uptake of these dyes by cancer cells and not by normal cells, as well as their high intensity, among other things, allow for the detection of cancerous cells in a subject and facilitate their subsequent isolation. Further, detection of many tumor types and tumor cell populations under cell culture and in vivo conditions are described.Type: ApplicationFiled: April 13, 2017Publication date: November 2, 2017Inventors: Xiaojian Yang, Haiyen E.
