Design, synthesis, and molecular docking of new 5-HT reuptake inhibitors based on modified 1,2-dihydrocyclopenta[b]indol-3(4H)-one scaffold

Abstract

A new group of serotonin reuptake inhibitors containing 1,2-dihydrocyclopenta[b]indol-3(4H)-one scaffold was synthesized, starting from indole 5-((1H-indol-3-yl)(1,3-dioxane-4,6-diones as a key intermediates. Following three transformations including intramolecular cyclization and formation of imines, a series of new ligand for human serotonin transporter was obtained. The ability of these ligands to inhibit human TS3 serotonin transporter as well as selectivity toward human D3 dopamine receptor and dopamine transporter were tested in silico using docking software. SYNOPSIS A series of new serotonin reuptake inhibitors containing 1,2-dihydrocyclopenta[b]indol-3(4H)-one scaffold were designed and synthesized. Affinity to human TS3 transporter and D3 receptor were tested in silico.
