A new series of quinazoline analogues was designed and synthesized to get the target compounds 18–21, 30–41, 46–53, and 57–76. The Obtained compounds were evaluated for their anticonvulsant activity using PTZ and picrotoxin convulsive models. Compounds 47, 63, 68 and 73 proved to be the most active compounds in this study with a remarkable 100% protection against PTZ induced convulsions. Compounds
一系列新的喹唑啉类似物的设计和合成,以获得目标化合物18 - 21,30 - 41,46 - 53,和57 - 76。使用PTZ和微毒素惊厥模型评估获得的化合物的抗惊厥活性。化合物47,63,68和73被证明是在本研究中最活跃的化合物与对PTZ诱发的惊厥的显着100%的保护。化合物47,63,68和73经证实,它们的活性分别是所用的阳性对照丙戊酸钠的10倍,4倍,4倍和5倍。结构活性相关性得出了有价值的药效学信息,这些信息已通过分子建模研究得到证实。68的分子对接研究表明其对GABA A受体的激动作用。研究的喹唑啉类似物可以被认为是未来开发和进一步衍生化的有用模板。
