Synthesis and antihepatotoxic activity of 5-(2,3-dihydro-1,4-benzodioxane-6-yl)-3-substituted-phenyl-4,5-dihydro-1H-pyrazole derivatives.

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 CCl(4)-induced hepatotoxicity in rats. Among them some compounds have shown significant antihepatotoxic activity comparable to standard drug silymarin.
