Compounds 7, 8, and 9, derived from the novel scaffolds 3, 5, and 6, were synthesized and evaluated in vitro. The b, c -> c,d shift of the E-phenyl ring resulted in a large decrease (ca. 20- to 1000-fold) in binding to the 5-HT2A, 5-HT2C and H-2, receptors, and a modest decrease (ca. 10- to 20-fold) in binding to the 5-HT5A, D-2, D-5, and alpha(1D), receptors. The b, c -> d, e shift resulted in a large decrease in binding to the 5-HT1D, 5-HT2C, 5-HT6, and H-1 receptors, a modest decrease in binding to 5-HT1A, 5-HT5A and D2, D5, alpha(2B), and H2 receptors, and a large increase in affinity to the 5-HT3, 5-HT6, and sigma(1) receptors.
