Publication number: 20240156990Abstract: The invention provides a 7-ethyl-10-hydroxycamptothecin drug precursor with fluorescence activity and a preparation method and use thereof. The method involves that a carboxyl group of a boron dipyrromethene dye molecule is condensed with a hydroxyl group at the 10 position of 7-ethyl-10-hydroxycamptothecin, yielding a 7-ethyl-10-hydroxy-camptothecin drug precursor (BDP-SN38) with fluorescent activity. BDP-SN38 shows good solubility and stability in most pharmaceutically acceptable solvents. Compared with SN38, BDP-SN38 exhibits comparable antitumor activity, has high tumor uptake capacity, and produces strong green fluorescence with the excitation of visible light, thus providing fluorescence-guided bioimaging and further treatment of residual tumors after drug treatment, and having good application prospects in the research of integrated diagnosis and treatment and effective tumor treatment.Type: ApplicationFiled: December 30, 2021Publication date: May 16, 2024Inventors: Zhengqing GUO, Yangyang HUANG, Dandan JI, Han XU, Hui HE, Dingding AI

Patent number: 11957752Abstract: The present invention relates to the technical field of photosensitizers, and particularly to a near-infrared nano-photosensitizer and a preparation method and use thereof. The near-infrared nano-photosensitizer in the present invention is modified by conjugation extension of the boron dipyrromethene core, achieving absorption and emission spectra close to the near-infrared region. A polyfluoroalkyl group and a polyethylene glycol group are introduced to the boron dipyrromethene structure to obtain an amphiphilic photosensitizer. By means of the strong fluorine-fluorine interaction between the polyfluoroalkyl group and the hydrophilic interaction of the polyethylene glycol group, a nano-photosensitive micelle with an ultra-low CMC value is ultimately constructed. Boron dipyrromethene is induced by fluorine-fluorine interaction to undergo J-aggregation, causing the maximum absorption peak to red-shift to the near-infrared region, beneficial to the deep phototherapy of tumors.Type: GrantFiled: January 25, 2022Date of Patent: April 16, 2024Assignee: SOOCHOW UNIVERSITYInventors: Zhengqing Guo, Hui He, Mengke Shi, Han Xu, Dandan Ji, Yangyang Huang, Qiujin He
