Discovery of Bishomo(hetero)arylpiperazines as Novel Multifunctional Ligands Targeting Dopamine D3 and Serotonin 5-HT1A and 5-HT2A Receptors

This is the authors' abstract. We don't add key points for this paper.

As a continuation of our efforts to develop innovative ligands for D(3), 5-HT(1A), and 5-HT(2A) receptors with low propensity to block hERG channels, we propose a series bishetero(homo)arylpiperazines 5a-m as novel and potent multifunctional ligands characterized by low occupancy at D(2) and 5-HT(2C) receptors.
