It has been proposed that 5-HT1A receptor antagonists augment the antidepressant efficacy of selective serotonin (5-HT) reuptake inhibitors. In a search toward new and efficient antidepressants, 1-(aryl)-3-[4-arylpiperazin-1-yl]-1-propane mol. hybrids were designed, synthesized, and evaluated for 5-HT reuptake inhibition and 5-HT1A receptor affinity. The design was based in coupling structural moieties related to inhibition of serotonin reuptake, such as benzo[b]thiophene derivatives to arylpiperazines, typical 5-HT1A receptor ligands. In binding studies, several compounds showed affinity at the 5-HT transporter and at 5-HT1A receptors. Mol. modeling studies predicted the pharmacophore elements required for high affinity binding and the features that enable to discriminate between agonist, partial agonist, or antagonist action at 5-HT1A receptors and 5-HT transporter inhibition. Solvent interactions in desolvation prior to the binding step along with enthalpy and entropy compensations might be responsible to explain agonist, partial agonist, and antagonist character. Hydrogen-bonding capability seems to be important to break hydrogen interhelical hydrogen bonds or alternatively to form other bonds upon ligand binding. Partial agonists and antagonists are unable to do this as the full agonist, which interacts closely by long-range forces or directly. The compounds showing the higher affinity at both the 5-HT transporter (Ki<50 nM) and the 5-HT1A receptors (Ki<20 nM) were further explored for their ability to stimulate [35S]GTPγS binding or to antagonize 8-hydroxy-2-di-n-propylamino-tetralin (8-OH-DPAT)-stimulated [35]GTPγS binding to rat hippocampal membranes, an index of agonist/antagonist action at 5-HT1A receptors, resp. Functional characterization was performed by measuring the antagonism to 8-OH-DPAT-induced hypothermia in mice. The experimental process involved the reaction of 4-(Piperazin-1-yl)-1H-indole(cas: 84807-09-0HPLC of Formula: 84807-09-0)
