Synthesis of enantiomerically pure milnacipran analogs and inhibition of dopamine, serotonin, and norepinephrine transporters
摘要:
A series of Milnacipran analogs with variation in the aromatic moiety were prepared in high enantionteric excess. Structure-activity relationships for two parallel enantionteric series are described. The (-)-(1R,2S)-naphthyl analog (8h) showed the highest potency in the two series and is a triple reuptake inhibitor of the SERT, NET, and DAT. (c) 2007 Elsevier Ltd. All rights reserved.
Synthesis of derivatives of (1S,2R)-1-phenyl-2-[(S)-1-aminopropyl]-N,N-diethylcyclopropanecarboxamide (PPDC) modified at the 1-aromatic moiety as novel NMDA receptor antagonists: the aromatic group is essential for the activity
(1S,2R)-1-Phenyl-2-[(S)-1-aminopropyl]-N,N-diethylcyclopropanecarboxamide (PPDC. 4a). which is a conformationally restricted analogue of antidepressant milnacipran [(+/-)-1]. is a new class of potent noncompetitive NMDA receptor antagonists. A series of PPDC analogues modified at the 1-phenyl moiety. that is, the analogue 6 lacking 1-phenyl group, the 1-(fluorophenyl) analogues 4b,c.d. the 1-(methylphenyl) analogues 4e-g and the 1-(naphthyl) analogues 4h.i were synthesized. Analogue 6. lacking the 1-phenyl group. was completely inactive showing that the aromatic moiety is essential for the NMDA receptor binding. Among the analogues synthesized, the 1-o-fluorophenyl and 1-m-fluorophenyl analogues 4b and 4c showed potent affinities for the NMDA receptor [IC50=0.16+/-0.001 muM (4b), 0.15+/-0.02 muM (4c)]. which were improved to some extent compared to those of the parent compound PPDC (IC50=0.20+/-0.02 muM). On the other hand, compounds 4b and 4c showed none of the 5-HT-uptake inhibitors effect, while PPDC turned out to be a weak 5-HT-uptake inhibitor. (C) 2002 Elsevier Science Ltd. All rights reserved.
