Kilbourn, Michael R. published the artcileSynthesis of fluorine-18-labeled flunarizine, Application of (E)-1-Cinnamylpiperazine, the publication is Applied Radiation and Isotopes (1991), 42(2), 109-11, database is CAplus and MEDLINE.
Flunarizine, a calcium channel antagonist of the piperazine class, has been labeled with the positron-emitter 18F. 4-[18F]fluoro-4′-fluorobenzhydryl chloride was prepared in 3 steps from no-carrier-added [18F]fluoride ion, and used in the alkylation of N-cinnamylpiperazine to give [18F]flunarizine in 13% radiochem. yield (from [18F]fluoride).
Applied Radiation and Isotopes published new progress about 87179-40-6. 87179-40-6 belongs to piperazines, auxiliary class Benzenes, name is (E)-1-Cinnamylpiperazine, and the molecular formula is C13H18N2, Application of (E)-1-Cinnamylpiperazine.
