pyl derivatives as well as their upper homologous butyl derivatives of various methylpiperidines were prepared. The piperidine moiety bearing monomethyl or geminal dimethyl groups was employed as a probe to explore sigma-subtype affinities and selectivities by radioligand binding assays at sigma(1) and sigma(2) receptors and the Delta(8)-Delta(7) sterol isomerase (SI) site. 4-Methyl derivative 31 was
制备了各种甲基哌啶的N-(6-甲氧基-1,2,3,4-四氢萘-1-基)丙基和N-(6-甲氧基萘-1-基)丙基衍生物以及它们的高级同源丁基衍生物。 。带有单甲基或双甲基二甲基基团的哌啶部分被用作探针,通过在sigma(1)和sigma(2)受体以及Delta(8)-Delta(7)固醇异构酶的放射性配体结合测定来探索sigma-subtype亲和力和选择性(SI)网站。4-甲基衍生物31是最有效的sigma(1)配体(K(i)= 0.030 nM),具有良好的选择性(相对于sigma(2)受体和SI位点分别为597倍和268倍),而3,3-二甲基衍生物26(K(i)= 0.35 nM)是相对于sigma(2)受体最具选择性的(680倍)。两种化合物都可以作为PET实验的工具。此外,
