Abstract

4-[18F]Fluoroiodobenzene ([18F]FIB) is a versatile building block in 18F radiochemistry used in various transition metal-mediated C-C and C-N cross-coupling reactions and [18F]fluoroarylation reactions. Various synthesis routes have been described for the preparation of [18F]FIB. However, to date, no automated synthesis of [18F]FIB has been reported to allow access to larger amounts of [18F]FIB in high radiochemical and chemical purity. Herein, we describe an automated synthesis of no-carrier-added [18F]FIB on a GE TRACERlab™ FX automated synthesis unit starting from commercially available(4-iodophenyl)diphenylsulfonium triflate as the labelling precursor. [18F]FIB was prepared in high radiochemical yields of 89 ± 10% (decay-corrected, n = 7) within 60 min, including HPLC purification. The radiochemical purity exceeded 95%, and specific activity was greater than 40 GBq/μmol. Typically, from an experiment, 6.4 GBq of [18F]FIB could be obtained starting from 10.4 GBq of [18F]fluoride.

Member of the APCaRI Training Program will present a poster at CARO ASM 2017 – Toronto

Congratulations to Dr. Deepak Dinakaran for getting his abstract “Comparison of Post-Radiotherapy Prostate Specific Antigen drop kinetics between External Beam Radiotherapy and Brachytherapy” accepted as a poster presentation at the Canadian Association of Radiation Oncology Annual Scientific Meeting (CARO ASM) 2017.

The 2017 CARO Annual Scientific Meeting will be held at the Hilton Toronto in Toronto, ON September 13-16, 2017.  This conference is for Radiation Oncologists, Medical Physicists, Radiation Therapists, Basic Science Researchers, Oncology Nurses, Administrators, as well as their trainees. All healthcare professionals involved in the care of oncology patients are also welcome to attend.

Dr. Dinakaran extracted and analyzed clinical data from the Alberta Prostate Cancer Registry for this study.
