Abstract:
Background: Epilepsy continues to be a significant global health problem and the search
for new drugs for its treatment remains an urgent task. 5-HT2 and GABAA-receptors are among
promising biotargets for the search for new anticonvulsants.
Methods: New potential 5-HT2 and GABAA ligands in the series of substituted cinnamoyl derivatives
of 3,4,6,7,8,9-hexahydrodibenzo[b,d]furan-1-(2H)-one oxime were designed using pharmacophore
model and molecular docking analysis. The synthesis of new compounds was carried out from
3,4,6,7,8,9-hexahydrodibenzo[b,d]furan-1(2H)-one oxime and substituted cinnamoyl chlorides. The
anticonvulsant activity of new substances has been established using the maximal electroshock seizure
test.
Results: Several synthesized substituted cinnamoyl derivatives of 3,4,6,7,8,9-hexahydrodibenzo
[b,d]furan-1-(2H)-one oxime significantly reduced the severity of convulsive manifestations and
completely prevented the death of animals after MES. The structure-activity relationship was investigated.
The most effective compound was found to be GIZH-348 (1g) (3,4,6,7,8,9-hexahydrodibenzo[
b,d]furan-1(2Н)-one О-(4-chlorophenyl)acryloyl)oxime) at the doses of 10-20 mg/kg.
Conclusion: Molecular and pharmacophore modelling methods allowed us to create a new group of
substituted cinnamoyl derivatives of 3,4,6,7,8,9-hexahydrodibenzo[b,d]furan-1-(2H)-one oxime with
anticonvulsant activity.
