Abstract
Di(het)areno-fused 1,4,7-(oxa)thiadiazecanes were synthesized by the reduction of the corresponding ten-membered lactams obtained, in turn, via the ‘hydrated imidazoline ring expansion’ (HIRE) methodology. Two of them displayed micromolar agonistic activity towards trace amine-associated receptor 1 (TAAR1) and no affinity towards a panel of dopamine (D2) and serotonin (5-HT1A, 5-HT2A and 5-HT7) receptors. These findings validate compounds of this chemotype as scaffolds for the design of selective aminergic receptor modulators.
