Publication number: 20160016958Abstract: Flumazenil (FMZ) is labeled with fluorine(F)-18 to obtain F-18-flumazenil. F-18-flumazenil can be strongly combined with type-A acceptor of gamma-aminobutyric acid (GABAA) in brain for tracing. The time and temperature for labeling is saved and lowered. The toxic chemical, acetonitrile, used in separation and purification can be prevented. The present invention has a simplified procedure for evaluating mental disease medicines in a short time.

Patent number: 9017646Abstract: A process of evaluating blood-brain barrier permeability of a stroke rat by using fluorescent substance is disclosed. This process uses an Evans blue dye having spontaneous fluorescence properties, in combination with the use of a new non-invasive in vivo imaging system (IVIS), to obtain fluorescent signals so as to assess the change in the blood-brain barrier permeability of rodents after a cerebral artery stroke model surgery. In operation, an Evans blue dye is injected into a stroke rat of middle cerebral artery occlusion model. A non-invasive in vivo imaging system is used to detect the fluorescence distribution of the whole brain, and obtain images combined by the fluorescence images and optical images for the whole brain tissue. Thereby, the change in the blood-brain barrier permeability of the stroke rat can be completely realized.Type: GrantFiled: July 10, 2012Date of Patent: April 28, 2015Assignee: Institute of Nuclear Energy Research, Atomic Energy CouncilInventors: Jun-Ming Shih, Yuan-Ruei Huang, Yu-Lung Wu, Shih-Ying Lee, Kang-Wei Chang, Chia-Chien Chen

Patent number: 8986652Abstract: The present invention provides a method of preparing [123I]Iodooctyl fenbufen amide with a radiochemical yield of 15%, a specific activity of 37 GBq/?mol and radiochemical purity of 95%. The present invention further provides a method of applying [123I]Iodooctyl fenbufen amide as tracer of single photon emission computer tomography (SPECT) to estimate the distribution of cyclooxygenase. By the binding characteristics of the iodine isotope-labeled compounds and the positive correlation of inflammation to tumor lesion, the present invention can estimate the tumor development and metastasis.Type: GrantFiled: February 1, 2013Date of Patent: March 24, 2015Assignee: National Tsing Hua UniversityInventors: Chung-Shan Yu, Ho-Lien Huang, Chun-Nan Yeh, Wei-Yuan Lee, Kang-Wei Chang, Ying-Cheng Huang, Kun-Ju Lin, Ching-Shiuann Yang, Shu-Fan Tien, Wen-Chin Su, Jenn-Tzong Chen, Wuu-Jyh Lin, Shiou-Shiow Farn

Publication number: 20120264949Abstract: A method is provided to label dopamine D2 receptors at striatum and areas outside of striatum. A radiosynthesized ligand of iodine(I)-123-Epidepride is used. The I-123-Epidepride can be strongly bonded to the D2 receptor and has a rare characteristic of non-specificity. Hence, it is suitable for developing a tracer for areas outside of striatum, where D2 receptor densities are low. Besides, I-123-Epidepride can be passed through blood brain barrier and has a high affinity to an animal's brain, so it can be used to develop medicines for diagnosing schizophrenia.Type: ApplicationFiled: April 13, 2011Publication date: October 18, 2012Applicant: ATOMIC ENERGY COUNCIL-INSTITUTE OF NUCLEAR ENERGY RESEARCHInventors: Shih-Ying Lee, Kang-Wei Chang, Chia-Chieh Chen

Publication number: 20100331577Abstract: There is disclosed a method for using 123I to radiolabel SnADAM become an serotonin transporter radiotracer(123I -ADAM). At first, there is provided SnADAM solution via mixing SnADAM with ethanol. The SnADAM solution is shaken and further mixed with thin KI solution. The SnADAM solution is mixed with 123I-NH4I solution and H2O2 solution. The SnADAM-123I-NH4I—H2O2 mixture is kept still. Later, the SnADAM solution is mixed with NaHSO3 solution, and the mixture is shaken and further mixed with buffer solution of saturated Na2HPO4. The SnADAM solution is filled in an Accubond C8 column. The Accubond C8 column is washed with sterile water for injection to isolate non-reacting 123I ions. The Accubond C8 column is washed with ethanol, thus providing 123I-ADAM. The 123I-ADAM is blended in normal saline mixture. Millipore Millex GV is used to filter impurities and bacteria from the 123I-ADAM solution.Type: ApplicationFiled: April 23, 2008Publication date: December 30, 2010Applicant: ATOMIC ENERGY COUNCIL-INSTITUTE OF NUCLEAR ENERGY RESEARCHInventors: Chia-Chieh Chen, Shih-Ying Lee, Hung-Chun Kao, Kang-Wei Chang, Li-Chung Hwang
