The design and synthesis of the novel 2,3,4,5-tetrahydro-1H-[1,4]diazepino[1,7-a]indole 5 is described. This azepinoindole has excellent affinity for 5-HT(2C) (K(i) 4.8 nM) and modest selectivity over 5-HT(2A) ( approximately 4-fold). Several N- and C(11)-substituted analogues of 5 were prepared, as were a number of biaryl indoline derivatives. The anxiolytic potential for the azepinoindole template 5 is demonstrated by activity in a mouse shock-aggression assay.

2,3,4,5-四氢和2,3,4,5,11,11a-六氢-1H- [1,4]二氮杂[1,7-a]吲哚：5-HT（2C）的新模板）激动剂。

描述了新颖的2,3,4,5-四氢-1H- [1,4]二氮杂ino [1,7-a]吲哚5的设计和合成。该氮杂吲哚具有对5-HT（2C）（K（i）4.8 nM）的优异亲和力和对5-HT（2A）的适度选择性（约4倍）。制备了5的几个N-和C（11）取代的类似物，以及许多联芳基二氢吲哚衍生物。通过在小鼠休克攻击试验中的活性证明了氮杂吲哚模板5的抗焦虑潜力。
