(PI = TD50/ED50) of 9.2. A computational study was also carried out, including prediction of pharmacokinetic properties and docking studies. The structural assignments of the newly synthesized compounds were elucidated on the basis of spectroscopic data and single-crystal X-ray crystallography. Graphical AbstractA series of new thiazole-based pyrrolidinones 5a–m and isoindolinediones 6a–l were synthesized
摘要合成了一系列新的1-(噻唑-2-基)吡咯烷-2-酮5a – m和2-(噻唑-2-基)异吲哚啉-1,3-二酮6a – n衍生物,并评估了其抗惊厥活性。该活动建立在三种癫痫发作模型中:PTZ,微毒素和MES。通过旋转脚踏试验选择出的化合物具有神经毒性。该系列中活性最高的化合物是1-(4-(萘-2-基)噻唑-2-基)吡咯烷酮-2-酮(5g),PTZ效应剂量(ED 50)值为18.4 mg / kg在小鼠中。中毒剂量(TD 50)为170.2 mg / kg,可提供保护指数(PI = TD 50 / ED 50)的9.2。还进行了计算研究,包括药代动力学特性预测和对接研究。在光谱数据和单晶X射线晶体学的基础上阐明了新合成化合物的结构分配。 图形概要合成了一系列新的基于噻唑的吡咯烷酮5a – m和异吲哚二酮6a – l,并作为抗惊厥药进行了测试。活性最高的化合物是1-(4-(萘-2-基)噻唑-2-基)吡咯烷酮-2-酮(5g),ED
