A series of aryl-substituted meperidine analogues was synthesized, and the binding affinities were determined at the DAT, SERT, and NET as well as at mu-opioid receptors. Generally the analogues exhibited increased affinity for the DAT and SERT relative to meperidine but exhibited low binding affinity for the NET. The 2-naphthyl derivative 7f was the most potent ligand at the SERT (K(i) = 0.0072 muM)
合成了一系列芳基取代的哌啶类似物,并在DAT,SERT和NET以及mu阿片受体上确定了结合亲和力。通常,相对于哌啶,所述类似物对DAT和SERT表现出增加的亲和力,但是对NET表现出低的结合亲和力。2-萘基衍生物7f是SERT上最有效的配体(K(i)= 0.0072 muM),并且是相对于DAT(DAT / SERT = 158)和mu阿片样物质受体(mu / SERT = 281)。3,4-二氯苯基衍生物7e是DAT上最有效的配体(K(i)= 0.125μM),是DAT相对于mu阿片样物质受体(mu / DAT = 16.3)最具选择性的配体,但仍然略多一些在DAT上对SERT具有选择性(DAT / SERT = 6.68)。三种化合物3 鉴定出4-二氯苯基衍生物7e和2-萘类似物6f和7f在DAT处比哌替啶更有效,并且表现出与哌啶相似的明确定义的双相多巴胺摄取抑制作用。然而,在药物辨别
