In continuance of our search for newer antihepatotoxic agents some novel pyrazoline derivatives containing 1, 4-dioxane ring system were synthesized starting from 3-(2, 3- dihydro-1, 4-benzodioxane-6-yl)-1-substituted-phenylprop-2-en-1-one. Some of the synthesized compounds were evaluated for antihepatotoxic activity against CCl4-induced hepatotoxicity in rats. Among them some compounds have shown significant ...
