H. Stadler et al., Structure-activity relationships of substituted 2,3,4,4a,5,10b-hexahydro-benz[h]isoquinoline-6(1H)-ones as 5-HT2C receptor antagonists, CHIMIA, 54(11), 2000, pp. 669-671
A series of cis and trans configured 2,3,4,4a,5,10b-hexahydro-benz[h]isoqui
noline-6(1H)-ones 2 were studied with respect to the binding affinity to th
e 5-HT2 subtype receptors. The influence of substituents in positions 7 (R-
1), 8 (R-2) and 9 (R-3) on affinity and selectivity to 5-HT2A and 5-HT2C re
ceptors and the preference of one diastereoisomer is discussed.
