In this study a new series of 3-aryloxy/arylthioxyacetylhydrazono-2-in
dolinones obtained by condensation,of isatin with aryoxy/arythioxyacet
ylhydrazines were treated with morpholine and formaldehyde to yield 3-
aryloxy/arylthioxyacetylhydrazone-2-indolinones. Structures of all the
compounds were assigned on the basis of spectral data (UV, IR, H-1-NM
R, EIMS) and elemental analyses. Anticonvulsant evaluation of the comp
ounds revealed varying degrees of activity against. pentylenentetrazol
e induced seizures.
