A series of 4-Phenyl-3-phenylamino-4H-[1,2,4]thiadiazol-5-one derivatives was synthesized by a simple method and their structures were established by physical and spectroscopic methods like infrared, mass and nuclear magnetic resonance spectroscopy. Elemental formulae of all the compounds were determined by elemental analysis and compared with the calculated value. Log P value and in vitro hydrolysis
通过简单的方法合成了一系列的4-苯基-3-苯基氨基-4H- [1,2,4]噻二唑-5-酮衍生物,并通过红外,质谱和核磁共振等物理和光谱方法确定了它们的结构。光谱学。通过元素分析确定所有化合物的元素式,并将其与计算值进行比较。记录P通过标准方法测定所有化合物在模拟胃液和模拟肠液中的pH值和体外水解。筛选合成的1、2、4-噻唑啉类药物对最大电击法和异烟肼诱发的癫痫发作的抗惊厥活性。所有化合物均显示出良好的抗惊厥活性。发现化合物4-(3,4-二氯-苯基)-3-(3,4-二氯-苯基氨基)-4H- [1,2,4]噻二唑-5-酮(3a)是最有效的系列的成员。合成化合物的分子对接研究表明它们具有稳定的配体-受体复合物构象,具有典型的γ-氨基丁酸A受体蛋白结合袋。化合物3a还通过与Tyr 157,Phe 200和Tyr 205(γ-氨基丁酸A受体蛋白4COF的关键相互作用残基)的非共价相互作用来限制其在分
