Abstract
The pharmacologically characterized receptor subtype of the serotonin family, the 5HT1A receptor is implicated in the pathophysiology and treatment of depression and anxiety-related disorders. Being the most extensively targeted receptor for developing novel antidepressants and anxiolytics, a near-ideal theoretical model can aid in high-throughput screening of promising drug candidates. However, the design of potential drug candidates suffers owing to a lack of complete structural information. In this work, homology models of 5-HT1A receptor are generated using two distinct alignments (CW and PSTA) and model building methods (KB and EB). The developed models are validated for virtual screening using a ligand dataset of agonists and antagonists. The best-suited model was efficient in discriminating agonist/antagonist binding. Correlation plots between pKi and docking (R2agonist≥ 0.6, R2antagonist≥ 0.7) and MM-GBSA dG bind values (R2agonist≥ 0.5, R2antagonist≥ 0.7) revealed optimum corroboration between in vitro and in silico outcomes, which further suggested the usefulness of the developed model for the design of high-affinity probes for the neurological disorders.Communicated by Ramaswamy H.

Abstract
A series of novel 3-indolylpropyl derivatives was synthesized and evaluated for their binding affinities at the serotonin-1A receptor subtype (5-HT1A R) and the 5-HT transporter (SERT). Compounds 11b and 14b exhibited the highest affinities at the 5-HT1A R (Ki = 43 and 56 nM), whereas compounds 11c and 14a were the most potent analogs at the SERT (Ki = 34 and 17 nM). On the other hand, compounds 14b and 11d showed potent activity at both targets, displaying a profile that makes them promising leads for the search for novel potent ligands with a dual mechanism of action. Molecular docking studies in all the compounds unveiled relevant drug-target interactions, which allowed rationalizing the observed affinities.

Abstract
The resurgence of interest in 5-HT1A receptors as a therapeutic target requires the existence of highly selective 5-HT1A ligands. To date, WAY-100635 has been the prototypical antagonist of these receptors. However, this compound also has significant affinity for and activity at D4 dopamine receptors. In this context, this work was aimed at better understanding the 5-HT1A/D4 selectivity of WAY-100635 and analogues from a structural point of view. In silico investigations revealed two key interactions for the 5-HT1A/D4 selectivity of WAY-100635 and analogues. First, a hydrogen bond only found with the Ser 7.36 of D4 receptor appeared to be the key for a higher D4 affinity for newly synthesized aza analogues. The role of Ser 7.36 was confirmed as the affinity of aza analogues for the mutant D4 receptor S7.36A was reduced. Then, the formation of another hydrogen bond with the conserved Ser 5.42 residue appeared to be also critical for D4 binding.
