Abstract
The 5-HT1A receptors are an important biological target in the treatment of CNS diseases. Recently, their importance in the context of non-CNS disease entities has also been postulated. In the light of these reports, we designed a new group of urea derivatives of N-aryl-N′-aryl-/(thio)ureido-/sulfamoylamino-derivatives of alkyl/alkylcarbamoyl piperazines as 5-HT1AR ligands, focusing on increasing receptor selectivity. We made structural modifications in three areas of the molecule. In the course of our research, we obtained a ligand with reduced basicity (6f), which, despite the loss of the protonable nitrogen atom, did not lose its affinity for the 5-HT1AR (Ki = 35 nM) with a simultaneous increase in selectivity. In particular, a decrease in affinity for D2R (Ki = 1940 nM) was observed, which was analyzed using molecular modeling methods, including FMO and molecular dynamics. Basic ADME-Tox parameters were characterized for 6f, confirming its potential applicability in pharmacotherapy.
