Synthesis and characterization of new Piperazine-Dithiocarbamate compounds as potent MAO-A inhibitors

Monoamine oxidase (MAO) enzymes have an important place in neurodegenerative diseases. While MAO-A inhibitors are used in depression; MAO-B enzyme has an important place in Parkinson's disease. Within the scope of this study, 7 new piperazine-dithiocarbamate derivative compounds were synthesized. Structure determinations of the compounds were performed using 1H-NMR, 13C-NMR and HRMS spectroscopic methods. The MAO inhibitory activities of the compounds were determined by in vitro fluorometric methods. According to the obtained results, compound 2d with IC50=0.108±0.004 µM; compound 2e exhibited inhibitory activity with an IC50=0.074±0.003 µM.
