Zwitterions such as farnesyl sulfobetaine 8 are a new type of inhibitor of squalene synthase that, while maintaining overall neutrality, mimic both the carbocationic and anionic moieties of presumed reaction intermediates. The most effective zwitterionic sulfobetaines discovered to date are aromatic derivatives 17 (IC50 = 2 mu M) and 20 (IC50 = 5 mu M). Copyright (C) 1996 Elsevier Science Ltd

A substantial number of sulfobetaines (e.g., 10) have been synthesized and evaluated as inhibitors of squalenesynthase (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
