Novel (benzo[1,3]dioxol-5-yloxy)-N′-(4-substituted benzylidene)acetohydrazide derivatives were synthesized and their anticonvulsant activity evaluated by MES and scMET seizure models. Compound 2-(benzo[d][1,3]dioxol-5-yloxy)-N′-benzylideneacetohydrazide (4a) was found to be most potent in MES seizure test and showed no neurotoxicity at the highest administered dose. All the compounds showed high docking score with γ-aminobutyric acid receptor, GABAAR-β3 homopentamer (PDB ID: 4COF). Thus, the probable mechanism of action of benzo[1,3]dioxol-5-yloxy-N′-(4-substituted benzylidene)acetohydrazide derivatives (4a-h) may be augmentation of GABAergic activity.
(苯并[1,3]二氧戊环-5-氧基)-N′-(4-取代苄叉)乙酰肼衍生物被合成,并通过MES和scMET癫痫模型评估了它们的抗惊厥活性。在MES癫痫测试中,化合物2-(苯并[d][1,3]二氧戊环-5-氧基)-N′-苄叉乙酰肼(4a)被发现是最有效的,并且在最高给药剂量下未显示出神经毒性。所有化合物与γ-氨基丁酸受体GABAAR-β3同源五聚体(PDB ID:4COF)的对接得分都很高。因此,苯并[1,3]二氧戊环-5-氧基-N′-(4-取代苄叉)乙酰肼衍生物(4a-h)的可能作用机制可能是增强GABA能活性。
