SYNTHESIS AND BIOLOGICAL EVALUATION OF SOME BIS-PYRAZOLE DERIVATIVES AS ANTICANCER AGENTS
Abstract:-
Cyclocondensation of chalcones 1a-f with the appropriate hydrazine afforded the corresponding 1,4- Bis(1,3-disubstituted-4,5-dihydro-1H-pyrazol-5-yl)benzene. Mild oxidation of these pyrazolines with bromine water yielded the corresponding pyrazoles derivatives. Biological screening of the prepared compounds revealed weak anticancer activity of these derivatives.
