Neuroleptic activity of chiral trans-hexahydro-gamma-carbolines

J Med Chem. 1986 Jan;29(1):8-19. doi: 10.1021/jm00151a002.


A series of trans-8-fluoro-5-(4-fluorophenyl)-2,3,4,4a,5, 9b-hexahydro-1H-pyrido[4,3-b]indoles with various N-2 substituents has been prepared and tested for neuroleptic activity [( 3H]spiroperidol binding and amphetamine antagonism). Several members of this series showed exceptional in vivo potency, especially the hydantoin derivatives 27-30. Resolution into the enantiomers showed that neuroleptic activity is associated with the 4aS,9bS absolute configuration. These rigid neuroleptics have been correlated with other rigid neuroleptics [(+)-dexclamol, Ro 22-1319] and can serve to further define the topography of the dopamine receptor.
