Novel, highly potent, selective 5-HT2A/D2 receptor antagonists as potential atypical antipsychotics

Bioorg Med Chem Lett. 2003 Feb 24;13(4):767-70. doi: 10.1016/s0960-894x(02)01028-4.

Abstract

The discovery of N-substituted-pyridoindolines and their binding affinities at the 5-HT(2A), 5-HT(2C) and D(2) receptors, and in vivo efficacy as 5-HT(2A) antagonists is described. The structure-activity relationship of a series of core tetracyclic derivatives with varying butyrophenone sidechains is also discussed. This study has led to the identification of potent, orally bioavailable 5-HT(2A)/D(2) receptor dual antagonists as potential atypical antipsychotics.
