title: Binding of beta-carbolines at 5-HT(2) serotonin receptors.
abstract: A series of ring-substituted (i.e., methoxy and bromo) 3,4-dihydro- and 1,2,3,4-tetrahydro-beta-carbolines was examined at 5-HT(2A) and 5-HT(2C) serotonin receptors. Whereas most of the methoxy-substituted derivatives typically displayed affinities similar to their unsubstituted parents, certain (particularly 8-substituted) bromo derivatives displayed enhanced affinity. A binding profile was obtained for selected beta-carbolines.
