Design and synthesis of new 5-arylhydantoins were performed.
5">Molecular modeling for examination of the 5-HT7R-ligand interactions was applied.
Affinities for 5-HT1AR, 5-HT7R, D2R in radioligand binding assay were evaluated.
5">Antagonistic activity at 5-HT7R of the 5-arylhydantoins was experimentally verified.
