Abstract
A series of new 2-pyrazoline derivatives has been synthesized by reacting 3-(substituted-phenyl)-1-pyridin-2-yl-propenones using two routes one using thiosemicarbazide and the other by hydrazine hydrate. The chemical structures were established by IR, Mass, 1H-NMR, 13C-NMR spectroscopic data, and elemental analysis. The anticonvulsant activity of the synthesized compounds was evaluated by the “maximal electroshock seizure” (MES) test and pentylenetetrazole (PTZ) test using male albino mice. Compounds 2e, 5-(naphthalene-1-yl)-3-(pyridine-2-yl)-4,5-dihydro-1H-pyrazole-1-carbothioic acid amide, and 3c, N-ethyl-5-(naphthalene-1-yl)-3-(pyridine-2-yl)-4,5-dihydro-1H-pyrazole-1-carbothioamide showed appreciable activity in the MES as well as PTZ test at all the evaluated doses.
