relationship between the 2(3H)-benzoxazolone and 2(3H)-benzothiazolone derivatives' structures and anticonvulsant activity. Several of these compounds showed significant anticonvulsant activity. Compounds 43 and 45 were the most active of the series against MES-induced seizures with ED50 values of 8.7 and 7.6 mg/kg, respectively. Compound 45 displayed good protection against MES-induced seizures and low toxicity
合成了一系列2(3H)-苯并恶唑酮和2(3H)-苯并噻唑酮衍生物,并评估了其抗惊厥活性。在小鼠腹膜内和在大鼠腹膜内对化合物进行了分析,以防最大电击(MES)和戊四氮(scMet)诱发的癫痫发作。通过旋转脚架试验评估神经功能缺损。制备化合物以确定2(3H)-苯并恶唑酮和2(3H)-苯并噻唑酮衍生物的结构与抗惊厥活性之间的关系。这些化合物中的几种显示出显着的抗惊厥活性。化合物43和45对MES引起的癫痫发作最有效,ED50分别为8.7和7.6 mg / kg。在口服ED50为18的大鼠中,化合物45对MES引起的癫痫发作显示出良好的保护作用,并且毒性低。6 mg / kg,保护指数(PI = TD50 / ED50)<26.9。体外受体结合研究表明,化合物43和45以纳摩尔亲和力与sigma 1受体结合。
