cis- and trans-2,3,3a,4,5,9b-Hexahydro-1H-benz[e]indoles: synthesis and evaluation of dopamine D2 and D3 receptor binding affinity
摘要:
cis- and trans-2,3,3a,4,5,9b-Hexahydro-1H-benz[e]indoles were synthesized as conformationally rigid analogues of 3-phenylpyrrolidine and evaluated for dopamine (DA) D-2S and D-3 receptor binding affinity. The tricyclic benz[e]indole nucleus was constructed by a previously reported reductive amination-cyclization procedure. Several unexpected side products were isolated and characterized using the general method. The trans-diastereoisomers exhibited greater affinities for the DA D-3 receptor than the corresponding cis-isomers. In both the cis- and trans- series the greatest affinity for DA D-3 receptors was shown by compounds substituted with N-n propyl or N-allyl groups. The cis-(+/-)-N-allyl derivative 21e demonstrated a D-2S /D-3 selectivity of 290. Resolution of cis-(+/-)-5 and trans-(+/-)-21c into individual enantiomers showed that in both series the more active isomer had 3aR absolute configuration. These novel Ligands may be useful tools for gaining additional information about the DA D-3 receptor. (C) Elsevier, Paris.
