Abstract
An easy and convenient microwave-assisted synthesis of a small library of indolic arylpiperazine derivatives is described. Parallel and mixed pool combinatorial methods are reported and compared. The described reactions are nucleophilic substitutions of several aromatic piperazines in presence of K2CO3. Good yields and short reaction times are the main aspect of these procedures. Binding assays shed additional light on the influence of the LCAPs on the 5-HT1A, 5-HT2A and 5-HT2C receptors affinity and allowed to disclose three interesting compounds as 5-HT2C, mixed 5-HT2A/5-HT2C and 5-HT1A/5-HT2C ligands (4i, 4l and 4d, respectively), with potential antiepileptic, anxiolytic or atypical antipsychotic agent therapeutical profiles.
