Fluorine-18 is one of the most widely used radionuclides for the production of radiopharmaceuticals for positron emission tomography (PET). The radiolabeling methods like nucleophilic, electrophilic, Cu mediated mechanisms or prosthetic groups are widely using to achieve high regioselective radio-chemical yields. It acts as a powerful tool to identify new drug targets through cellular uptake, pharmacokinetic (ADME) and pharmacodynamic parameters of the F-18 labeled tracer or drug. These PET tracers have been developed based on the receptors expressed in a disease condition. A number of F-18 radiotracers have been developed against the Tropomyosin Receptor Kinases (Trks), Carbonic anhydrases (CAs), Epidermal Growth Factor Receptors (EGFR), Poly ADP ribose polymerase (PARP) etc. for the diagnosis in cancer therapy. The current research also focused on the development of novel F-18 radiotracers for neurological conditions for deciphering underlying physiology in diseases like Alzheimer, and Parkinson. Therefore, in this review we have focused on F-18 labeling methods, and radiotracers developed against common cancers and neurological conditions. (C) 2019 Elsevier Masson SAS. All rights reserved.

Synthetic methodologies and PET imaging applications of fluorine-18 radiotracers: a patent review

Sridhar Goud Nerella, Ahana Bhattacharya, Pavitra S. Thacker, Sanam Tulja

Summary: Fluorine-18 is a promising radionuclide for developing novel PET radiotracers due to its characteristic features such as convenient half-life, metabolic stability, good imaging properties, and easy access to various clinical PET centers. This review covers the patents and research papers of F-18-radiotracers with clinical applications in various diseases using PET modality since 2015 until the present. Despite other PET radionuclides C-11, N-13, and O-15, F-18 is widely used for radiotracer development because it has a maximum half-life of 109.8 min. Various synthetic methodologies have been developed for radiofluorination using nucleophilic, electrophilic, transition metal mediated, and prosthetic groups mediated reactions. Automated radiosynthesis methods have also been adapted for easy and convenient synthesis of F-18-radiotracers.
