title: Neuroleptic activity in 5-aryltetrahydro-gamma-carbolines.
abstract: A series of 5-aryltetrahydro-gamma-carbolines was prepared by a novel N-arylation procedure and tested for neuroleptic activity in a rat antiamphetamine model. The systematic exploration of structural parameters leading to 8-fluoro-5-(4-fluorophenyl)-2-[4-hydroxy-4-(4-fluorophenyl)butyl]-2,3,5-tetrahydro-1H-pyrido[4,3-b]indole (CP-36,584, flutroline), a potent and long-acting neuroleptic compound, is described. These semirigid compounds provide a new, structurally distinct series with which to probe the conformational requirements for potent activity at the dopamine receptor.
