A new series of 6,7-dihydro-[1,3,4]thiadiazolo[3,2-a][1,3]diazepine analogues were synthesized, and biological evaluated. Compound GS-62 (33) exhibited potent in vivo short acting hypnotic activity with onset time, duration of sleep and therapeutic index of 6.4 ± 0.2, 94.8 ± 5.3 min, 6.62, respectively), in comparison to thiopental sodium (6). Compounds 33 did not show any sign of acute tolerance reported
合成了一系列新的6,7-二氢-[1,3,4]噻二唑[3,2- a ] [1,3]二氮杂analogue类似物,并对其进行了生物学评估。与硫喷妥钠(6)相比,化合物GS-62(33)表现出强大的体内短效催眠活性,其起效时间,睡眠时间和治疗指数分别为6.4±0.2、94.8±5.3分钟,6.62 。维持剂量为6时,化合物33没有显示出任何急性耐受的迹象。同时33增强了6的体内催眠作用等摩尔量(0.06 mmol)的组合分别显示起效和持续时间分别为7.5±1.3、62.5±5.9分钟。这种组合允许使用较低剂量的两种药物,以避免不良的副作用。对接研究揭示了良好的相互作用和与GABA A受体的BDZ结合位点的结合,尤其是与Arg87,Arg149和Thr151氨基酸残基的结合。
