the binding of 2 at sigma-sites. It is also demonstrated that an N-substituted aminotetralin moiety (such as 17, a conformationally restricted analogue of 2) may also be considered a sigma-opiate pharmacophore. Unlike the sigma-opiates, derivatives of 2 and 17 display no affinity for PCP sites and must consequently lack those structural features important for the binding of benzomorphans at PCP sites
某些苯并吗啡喃,例如N-烯丙基甲吗啉,是经典的“σ-鸦片制剂”,它们以适度的亲和力在sigma和苯环利定(PCP)结合位点结合。最近,我们确定N-取代的2-苯基氨基乙烷为苯并吗啡的主要sigma-pharmacophore,并证明1-苯基-2-氨基丙烷(2)衍生物,取决于其末端胺取代基,构成了一类新的高亲和力sigma选择剂。使用这种药效基团,在本研究中表明,芳族羟基(所有sigma-阿片剂的主要特征)对sigma-sites上2的结合几乎没有贡献。还证明了N-取代的氨基四氢萘部分(例如17,构象受限的2的类似物)也可以被认为是西格玛-鸦片药效团。与Sigma-鸦片不同,2和17的衍生物对PCP位点没有亲和力,因此必须缺少对PCP位点结合苯并吗啡酮重要的结构特征。因为3-苯基哌啶和相关的sigma-配体还具有嵌入其结构中的苯基烷基胺,所以我们提出2-苯基氨基乙烷部分是2、3-苯基哌啶和si
