Enantiomeric alcohols 15 (1S,2S,5R) and ent-15 (1R,2R,5S) as well as diastereomeric methyl ethers ent-17 (1R,2R,5S) and ent-22 (1R,2S,5S) display high sigma1 receptor affinity. Cell growth inhibition of the stereoisomeric alcohols and methyl ethers against five human tumor cell lines is investigated. In particular, at a concentration of 20 muM the four methyl ethers stop completely the cell growth of
所有可能的立体异构醇(6-苄基-8-(4-甲氧基苄基)-6,8-二氮杂双环[3.2.2]壬南-2-醇)和甲基醚(6-苄基-2-甲氧基-8-(4-由(R)-和(S)-谷氨酸制备甲氧基苄基)-6,8-二氮杂双环[3.2.2]壬烷。Dieckmann类似物环化利用了Me3SiCl捕获主要的环化产物,从而生成了双环骨架。立体选择性LiBH4还原和Mitsunobu转化建立了位置2的构型。对映体醇15(1S,2S,5R)和ent-15(1R,2R,5S)以及对映体甲基醚ent-17(1R,2R,5S)和ent-22(1R,2S,5S)显示高sigma1受体亲和力。研究了立体异构醇和甲基醚对五种人类肿瘤细胞系的细胞生长抑制作用。特别是,当浓度为20μM时,四种甲基醚完全停止了小细胞肺癌细胞系A-427的细胞生长,表明该细胞系中有特定的靶标。甲基醚ent-17和ent-22的IC50值在抗肿瘤药顺铂和奥
