Thirty new 2-(substituted)-3-[substituted]amino}quinazolin-4(3H)-one were designed and synthesized keeping in view the structural requirement of pharmacophore and evaluated for anticonvulsant activity and neurotoxicity. The anticonvulsant activity of the titled compounds was assessed using the 6 Hz psychomotor seizure test. The most active compound of the series was 3-((E)-[3-(4-chloro-3-methylp
考虑到药效团的结构要求,设计并合成了三十种新的2-(取代的)-3-[取代的]氨基}喹唑啉-4(3 H)-1 ,并评价了其抗惊厥活性和神经毒性。使用6Hz精神运动性癫痫发作测试评估标题化合物的抗惊厥活性。该系列中活性最高的化合物是3-((E)-[3-(4-氯-3-甲基苯氧基)苯基]亚甲基}氨基)-2-苯基喹唑啉-4(3 H)-一个PhQZ 7在小鼠中以100 mg / kg的剂量显示100%的保护(4/4,0.5 h)和75%的保护(3/4,0.25 h)。进行了计算研究,以计算药效团模式和预测药代动力学特性。在基于Lamarckian遗传算法的灵活对接研究中,标题化合物还具有与癫痫分子靶标(例如谷氨酸,GABA(A)δ和GABA(A)α-1受体)的良好结合特性。
