A series of 6-substituted-[3-substituted-prop-2-eneamido] benzothiazole 9–32 and 6- substituted-2-[(1-acetyl-5-substituted)-2-pyrazolin-3-yl] aminobenzothiazole 33–56 were synthesized using appropriate synthetic route and evaluated experimentally against maximal electroshock test. Selected compounds were evaluated for neurotoxicity, hepatotoxicity and behavioral study. The most active compound, 6-methyl-2-[(1-acetyl-5-(4 ...
