Design, Synthesis and Evaluation of 8-Thiosubstituted 1,3,7- Trimethylxanthine Hydrazones with In-vitro Neuroprotective and MAO-B Inhibitory Activities
Objective: The syntheses and biological activities of 8-thiosubstituted-1,3,7- trimethylxanthine derivatives bearing an aromatic hydrazide-hydrazone fragment in the side chain at C8 are described. Methods: The chemical structures of the synthesized compounds 6a-m were confirmed based on their MS, FTIR, 1H NMR and 13C NMR analyses. Results: The in vitro investigations of neuroprotective effects manifested
