2-(1,3-benzothiazol-2-ylsulfanyl)-N′-(substituted)acetohydrazide 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 2-(1,3-benzothiazol-2-ylsulfanyl)-N′-[4
设计并合成了一系列的2- [2-(取代)肼基] -1,3-苯并噻唑和2-(1,3-苯并噻唑-2-基硫烷基)-N '-(取代)乙酰肼。药效团的要求并评估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2-(1,3-苯并噻唑-2-基硫烷基)-N '-[4-(4-溴苯氧基)亚苄基]乙酰肼BT 15,以100 mg / kg的剂量在小鼠中显示出75%的保护(3 / 4,1.0小时)和50%的保护(2 / 4,0.5小时)。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GABA(A)alpha-1,谷氨酸,GABA(A)delta受体和Na / H交换子)的良好结合特性。
