A series of novel 3-indolylpropyl derivatives was synthesized and evaluated for their binding affinities at the serotonin-1A receptor subtype (5-HTb>1Ab>R) and the 5-HT transporter (SERT). Compounds <b>11bb> and <b>14bb> exhibited the highest affinities at the 5-HTb>1Ab>R (Kb>ib> = 43 and 56 nM), whereas compounds <b>11cb> and <b>14ab> were the most potent analogs at the SERT (Kb>ib> = 34 and 17 nM). On the other hand, compounds <b>14bb> and <b>11db> 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.
