Disclosed are a pyridyl imidazobenzodiazepine propionate (compound 1) and the synthesis and use thereof. Also provided are intermediates for the preparation. Compound 1 provided by the present invention has an obvious venous anesthesia activity equivalent to that of the positive control drug remimazolam p-toluenesulfonate or remimazolam besylate. In addition, compound 1 can be significantly reduced in mouse model experiments, and same can even overcome common limb jitters, head tilting, opisthotonus and other side effects caused by the remimazolam besylate or remimazolam p-toluenesulfonate as a drug during development in preclinical animal experiments, thereby allowing same to be used in the preparation of intravenous anesthetics. The structural general formula of compound 1 is as follows, wherein each group and substituent are as defined in the description.
本发明公开了一种吡啶基咪唑苯并二氮杂卓丙酸酯(化合物 1)及其合成和使用方法。还提供了用于制备的中间体。本发明提供的化合物 1 具有明显的静脉麻醉活性,与阳性对照药物对甲苯磺酸雷马唑仑或苯磺酸雷马唑仑相当。此外,化合物1在小鼠模型实验中可以明显降低麻醉活性,甚至可以克服苯磺酸雷马唑仑或对甲苯磺酸雷马唑仑作为药物在临床前动物实验开发过程中常见的肢体抖动、头部倾斜、opisthotonus等副作用,从而可以用于制备静脉麻醉药。化合物 1 的结构通式如下,其中各基团和取代基如描述中所定义。
