Jevtic, Ivana I.;Lai, Thu Hang;Penjisevic, Jelena Z.;Dukic-Stefanovic, Sladjana;Andric, Deana B.;Brust, Peter;Kostic-Rajacic, Sladjana V.;Teodoro, Rodrigo research published 《 Newly synthesized fluorinated cinnamylpiperazines possessing low in vitro MAO-B binding》, the research content is summarized as follows. Herein, the synthesis and pharmacol. evaluation of ten novel fluorinated cinnamylpiperazines I (R = 2-fluorophenyl, phenyl; R1 = (4-fluorophenyl)carbonyl, 2-fluoropyridin-3-yl, 6-fluoropyridin-2-yl, etc.)as potential monoamine oxidase B (MAO-B) ligands were reported. The designed derivatives I consist of either cinnamyl or 2-fluorocinnamyl moieties connected to 2-fluoropyridylpiperazines. The three-step synthesis starting from com. available tert-Bu piperazine-1-carboxylate afforded the final products I in overall yields between 9% and 29%. An in vitro competitive binding assay using l-[3H]Deprenyl as radioligand was developed and the MAO-B binding affinities of the synthesized derivatives I were assessed. Docking studies revealed that the compounds I were stabilized in both MAO-B entrance and substrate cavities, thus resembling the binding pose of l-Deprenyl. Although the results revealed that the novel fluorinated cinnamylpiperazines I do not possess sufficient MAO-B binding affinity to be eligible as positron emission tomog. (PET) agents, the herein developed binding assay and the insights gained within our docking studies will certainly pave the way for further development of MAO-B ligands.
