A substantial number of sulfobetaines (e.g., 10) have been synthesized and evaluated as inhibitors of squalene synthase (SS) on the basis of the idea that their zwitterionic structure would have properties conducive both to binding in the active site and to passage through cell membranes. When the simple sulfobetaine moiety is incorporated into compounds containing hydrophobic portions like those in
已经合成了大量的磺基甜菜碱(例如10种),并根据其两性离子结构具有有助于在活性位点结合和通过细胞膜通过的特性,被认为是鲨烯合酶(SS)的抑制剂。 。当将简单的磺基甜菜碱部分掺入含有疏水部分的化合物中时,如法呢基二磷酸酯(1)或角鲨烯二磷酸酯(2)中的那些,确实在大鼠肝微粒体测定中观察到了SS的抑制作用。例如,法呢基化磺基甜菜碱10具有抑制SS的IC(50)=10μM,而芳香族衍生物35具有IC(50)=2μM。研究了多种结构修饰,例如化合物43、52、76、85、91、99、111和115。不幸,
