2,3,4,5-tetrahydro- and 2,3,4,5,11,11a-hexahydro-1H-[1,4]diazepino[1,7-a]indoles: new templates for 5-HT(2C) agonists

Bioorg Med Chem Lett. 2003 Jul 21;13(14):2369-72. doi: 10.1016/s0960-894x(03)00403-7.

Abstract

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.
