摘要:
A series of new 3-amino, 3-aminomethyl-5-alkoxy-3,4-dihydro-2H-1-benzopyran and 5-alkoxy-3',4'-dihydrospiro[piperazine-2,3'(2'H)-benzopyran] derivatives was prepared and evaluated for affinity at 5-HT1A, 5-HT2A and D-2 receptors. Two of the compounds (1f and 2b) can be considered as potent and selective 5-HT2A ligands. One compound (1g) demonstrated high affinity for 5-HT1A and D-2 receptor binding sites and one compound (1d) proved to be a mixed 5-HT1A/5-HT2A ligand. (C) 2000 Elsevier Science Ltd.
