Abstract
6-Phenyl(3᾽-imino-benzylidene)-2,3,4,5-tetrahydro pyridazin-3-one derivatives were synthesized from 6-(3᾽-aminophenyl)-2,3,4,5-tetrahydro pyridazin-3-one by reaction with different aldehydes. The respective pyridazinone was prepared by cyclization of appropriate β-(aminophenyl) propionic acid with hydrazine hydrate. The pyridazinone derivatives were tested for anticonvulsant activity by MES (maximal electro shock) method and found that few of them have shown significant anticonvulsant activity.
