4 dinitro phenyl hydrazine hydrate

The novel Pyrazoline derivatives were prepared  by cyclisation of substituted chalcone derivatives in the presence of 2, 4 dintro phenyl hydrazine hydrate. Structural elucidation of all synthesized  derivatives were done by spectral analysis ( IR , NMR and Mass spectroscopy). All synthesized derivatives  screened for their anticancer activities by MTT assay and  these prepared derivatives exhibits promising anticancer activities.
