of meperidine analogues was synthesized and the binding affinities for the dopamine and serotonin transporters were determined. The substituents on the phenyl ring greatly influenced the potency and selectivity of these compounds for the transporter binding sites. In general, meperidine (3) and its analogues were more selective for serotonin transporter binding sites and the esters 9 were more potent

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
