title: Cationic cyclocholamides; toroidal facial amphiphiles with potential for anion transport.
abstract: Cholic acid has been transformed into cyclotrimeric and cyclotetrameric toroidal amphiphiles with inward-directed ammonium substituents; the cyclotrimer effects the transport of chloride anions across vesicle bilayer membranes.
