amino transferase (GABA-AT) in Lamarckian genetic algorithm based flexible docking studies. Compound D 8, N 1-(4-chlorobenzylidene) nicotinohydrazide was found to be the most potent analog with ED50 value of 16.1 mg/kg and protective index (PI = TD50/ED50) value of >20, which was much greater than that of the prototype drug phenytoin (PI = 6.9). It has shown free binding energy value of −10.20 kcal/mol
合成了一系列取代的芳族酰肼(D 1至D 20)的芳酸azo,并评价了其抗惊厥活性。烟酸酰肼(D 8,D 9和D 10)的芳酰azo在最大的电击筛选中显示了出色的保护作用。在基于Lamarckian遗传算法的灵活对接研究中,这些化合物还显示了与γ氨基丁酸氨基转移酶(GABA-AT)的Lys 329残基的优异结合特性。化合物D 8,N 1发现(-4-氯苄叉)烟酰肼是最有效的类似物,ED 50值为16.1 mg / kg,保护指数(PI = TD 50 / ED 50)值> 20,远大于原型样品。药物苯妥英钠(PI = 6.9)。它显示出对GABA-AT的自由结合能值为-10.20 kcal / mol,抑制常数(Ki)值为33.30 nM,这表明烟酸酰肼的芳酸azo可作为新型抗惊厥药的设计中的新药效团。毒品。
