Abstract Methods for the preparation of new condensed derivatives of pyrido[3',2':4,5]thieno[3,2-d]pyrimidines based on 5,6-dimethyl-2-oxo-1,2-dihydropyridine-3-carbonitrile were developed. Substitution reactions in the 3rd and 4th positions of 7,8-dimethylpyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4(3H)-one were conducted. The neurotropic activity of 12 obtained compounds was studied in vivo in rats
摘要 基于5,6-二甲基-2-氧代-1,2-二氢吡啶-3-的吡啶并[3',2':4,5]噻吩并[3,2 - d ]嘧啶新缩合衍生物的制备方法开发了腈。进行了 7,8-二甲基吡啶并[3',2':4,5]噻吩并[3,2- d ]嘧啶-4(3 H )-one的第 3 位和第 4 位的取代反应。在大鼠和小鼠体内研究了 12 种获得的化合物的神经活性。发现八种化合物具有与可唑拮抗的抗惊厥作用。四种选定的化合物具有抗焦虑和行为激活作用。对合成的化合物进行分子对接以预测它们与 GABA A的相互作用受体。鉴定出五种化合物,它们与 GABA A受体的络合发生在两个地方:亚位点 1 的苯甲脒位点和 ECD 界面的亚位点 3,这表明化合物对靶标的抑制作用。
