and propylenedioxy groups. These ligands, along with 4-O-des-methyl SA4503, were evaluated for σ1 and σ2 receptor affinity, and compared to SA4503 and several known ether analogs. SA4503 and a subset of ether analogs were also evaluated for dopamine transporter (DAT) and serotonin transporter (SERT) affinity. The highest σ1 receptor affinities, Ki values of 1.75–4.63 nM, were observed for 4-O-des-methyl
已经制备了两个系列的σ(σ)受体配体1-[2-(3,4-二甲氧基苯基)乙基]-4-(3-苯基丙基)哌嗪(SA4503)的新型醚类似物。在一系列中,4-甲氧基的烷基部分被烯丙基、丙基、溴乙基、苄基、苯乙基和苯丙基部分取代。在第二个系列中,3,4-二甲氧基被环状亚甲二氧基、亚乙二氧基和亚丙二氧基取代。对这些配体以及 4- O - des-甲基 SA4503 的 σ 1和 σ 2受体亲和力进行了评估,并与 SA4503 和几种已知的醚类似物进行了比较。还评估了 SA4503 和醚类似物的子集的多巴胺转运蛋白 (DAT) 和血清素转运蛋白 (SERT) 亲和力。 4- O - des -methyl SA4503、SA4503 和亚甲二氧基类似物观察到最高的 σ 1受体亲和力, K i值为 1.75–4.63 nM。随着空间体积的增加, σ1受体亲和力降低,但仅降低到一定程度。烯丙基、丙基和溴乙基取代使
