Three selectively fluorinated cinacalcet analogues are prepared and their activity as calcium-sensing receptor (CaR) agonists is assessed. Individual (2R,1′R)-2 and (2S,1′R)-3 fluorocinacalcet diastereoisomers were prepared using the MacMillan asymmetric fluorination reaction. Assays with the recombinant human CaR revealed that both diastereoisomers have a similar potency to each other although slightly lower (75–80%) than that of cinacalcet 1. The SF5-cinacalcet analogue 4 was prepared from meta-pentafluorosulfanyl benzyl alcohol and has ∼75% agonist activity relative to cinacalcet 1 indicating that the SF5 group can replace the CF3 group and retain significant bioactivity.
制备了三种选择性氟化的西那卡塞类似物,并评估了它们作为钙敏感受体 (CaR) 激动剂的活性。使用 MacMillan 不对称氟化反应制备单独的 (2R,1'R)-2 和 (2S,1'R)-3 氟西那卡塞非对映异构体。对重组人 CaR 的分析显示,两种非对映异构体具有相似的效力,尽管略低于西那卡塞 1 (75–80%)。SF5-西那卡塞类似物 4 由间五氟硫烷基苯甲醇制备而成,具有~75相对于西那卡塞1的%激动剂活性表明SF5组可以替代CF3组并保留显着的生物活性。
