A series of tetrahydro-1H-1,4-diazepines 4a–c, dihydro-1H-1,4-diazepine 5 and pyrido diazepines 8 and 10 was prepared. Originated form dehydroacetic acid (DHA) and aromatic aldehydes cinnamoyl compounds 3a–c were obtained and converted with ethylenediamine to give tetrahydro-1H-1,4-diazepines 4a–c. For the synthesis of pyrido[1,2-d][1,4]diazepines 8 and 10 a new snythetic approach is described. Compounds 4b and 5 were investigated concerning their affinity to different benzodiazepine receptor subtypes. The determined IC50 values for 5 are 1.5 μM and 1.1 μM at 10 μM respectively.
制备了一系列四氢-1H-1,4-二氮杂萘4a–c、二氢-1H-1,4-二氮杂萘5以及吡啶二氮杂萘8和10。这些化合物源自去氢乙酸(DHA)和芳香醛,得到了肉桂酸酯化合物3a–c,并与乙二胺反应,生成了四氢-1H-1,4-二氮杂萘4a–c。关于吡啶[1,2-d][1,4]二氮杂萘8和10的合成,描述了一种新的合成方法。化合物4b和5的亲和力被研究了不同的苯二氮平受体亚型。对于5所测得的IC50值分别为1.5 μM和1.1 μM(在10 μM的浓度下)。
