were synthesized using appropriate synthetic route and evaluated experimentally against maximal electroshock test. Selected compounds were evaluated for neurotoxicity, hepatotoxicity and behavioral study. The most active compound, 6-methyl-2-[(1-acetyl-5-(4-chlorophenyl))-2-pyrazolin-3-yl]aminobenzothiazole 52 exhibited an ED50 of 25.49 μmol/kg, TD50 of 123.87 μmol/kg and high protective index (PI)
一系列6取代的- [3-取代丙-2- eneamido]苯并噻唑的9 - 32和6-取代-2 - [(1-乙酰基-5-取代的)-2-吡唑啉-3-基]氨基苯并噻唑33 –使用适当的合成路线合成了56个,并针对最大电击试验进行了实验评估。评价所选化合物的神经毒性,肝毒性和行为研究。活性最高的化合物6-甲基-2-[((1-乙酰基-5-(4-氯苯基))-2-吡唑啉-3-基]氨基苯并噻唑52的ED 50为25.49μmol/ kg,TD 50与标准药物苯妥英钠相比,其抗氧化能力为123.87μmol/ kg,高保护指数(PI)为4.86。通过PHASE程序进行了3D-QSAR分析,并获得了具有良好预测能力(r 2 = 0.9220,q 2 = 0.8144)的统计可靠模型。3D-QSAR图解说明了对这些化合物的结构活性关系的了解,这可能有助于设计有效的氨基苯并噻唑衍生物作为抗惊厥药。
