NMDA receptor affinities of 1,2-diphenylethylamine and 1-(1,2-diphenylethyl)piperidine enantiomers and of related compounds
摘要:
We resolved 1,2-diphenylethylamine (DPEA) into its (S)- and (R)- enantiomer and used them as precursors for synthesis of (S)- and (R)-1-(1,2-diphenylethyl)piperidine,flexible homeomorphs of the NMDA channel blocker MK-801. We also describe the synthesis of the dicyclohexyl analogues of DPEA. These and related compounds were tested as inhibitors of [(3)H]MK-801 binding to rat brain membranes. Stereospecificity ranged between factors of 0.5 and 50. Some blockers exhibited stereospecific sensitivity to the modulator spermine. Our results may help to elucidate in more detail the NMDA channel pharmacophore. (C) 2009 Elsevier Ltd. All rights reserved.
