We synthesized and investigated the NMDA and σ₁ receptor affinity of enantiomerically pure 2-(2-phenyl-1,3-dioxan-4-yl)ethanamines 17-26. The primary amines (R,R)-18-20 with an axially oriented phenyl moiety in position 2 interacted with high enantioselectivity (eudismic ratios 70-130) and high affinity (K(i)((R,R)-19) = 13 nM) with the PCP binding site of the NMDA receptor. Introduction of an N-benzyl moiety led to potent σ₁ ligands including compound (S,R)-22 (K(i) = 6 nM) with an equatorially oriented phenyl moiety in position 2.
我们合成并研究了对映体纯 2-(2-苯基-1,3-二恶烷-4-基)乙胺 17-26 对 NMDA 和 σ₁ 受体的亲和力。在位置 2 具有轴向定向的苯基部分的伯胺 (R,R)-18-20 与 NMDA 受体的 PCP 结合位点具有高对映选择性(外消旋比 70-130)和高亲和力(K(i)((R,R)-19) = 13 nM)。引入 N-苄基部分导致产生了强效的 σ₁ 配体,包括化合物 (S,R)-22(K(i) = 6 nM),其在位置 2 具有赤道定向的苯基部分。
