derivatives of ethyl 8-oxo-5,6,7,8-tetrahydro-thiazolo[3,2-a][1,3]diazepin-3-carboxylate (HIE-124, 3), were synthesized as continuation to our previous patented efforts. Compounds 15 and 20 showed marginal hypnotic potency compared to 3. Compounds 15 (0.78 mmol/kg) and 20 (0.39 mmol/kg) showed remarkable 100% protection against PTZ induced convulsions with two and four fold increase in activity than sodium
乙基的新衍生物-8-氧代-5,6,7,8-四氢-噻唑并[3,2-一个] [1,3]二氮杂-3-羧酸乙酯(HIE-124,3),合成为延续到我们的先前的专利工作。与3相比,化合物15和20表现出较小的催眠效力。化合物15(0.78 mmol / kg)和20(0.39 mmol / kg)对PTZ引起的惊厥显示出显着的100%保护作用,其活性分别比丙戊酸钠(1.38 mmol / kg)高出2倍和4倍。分子模型研究表明,GABA A结合位点的15个残基和Thr56个残基之间存在氢键相互作用。叠加,柔性对准和的表面映射15,20和地西泮支持它们的生物学相似性,其中ADMET研究表明,那些化合物可作为抗惊厥药口服。
