Title: Synthesis of Diverse 11C-Labeled PET Radiotracers via Direct Incorporation of [ 11C]CO 2

Three new positron emission tomography (PET) radiotracers of interest to our functional neuroimaging and translational oncology programs have been prepared through new developments in [ 11C]CO 2 fixation chemistry. [ 11C]QZ (glutaminyl cyclase) was prepared via a tandem trapping of [ 11C]CO 2/intramolecular cyclization; [ 11C]tideglusib (glycogen synthase kinase-3) was synthesized through a tandem trapping of [ 11C]CO 2 followed by an intermolecular cycloaddition between a [ 11C]isocyanate and an isothiocyanate to form the 1,2,4-thiadiazolidine-3,5-dione core; [ 11C]ibrutinib (Bruton’s tyrosine kinase) was synthesized through a HATU peptide coupling of an amino precursor with [ 11C]acrylic acid (generated from [ 11C]CO 2 fixation with vinylmagnesium bromide). All radiochemical syntheses are fully-automated on commercial radiochemical synthesis modules and provide radiotracers in 1 – 5% radiochemical yield (non-corrected, based upon [ 11C]CO 2). In addition, all three radiotracers have advanced to rodent imaging studies and preliminary PET imaging results are also reported.
