title: Stabilizing guanosine-sterol ion channels with a carbamate to urea modification in the linker.
abstract: The use of a bis-urea lithocholamide linker within a guanosine-sterol dimer resulted in formation of large and stable ion channels. The channels were longer-lived than those formed by the corresponding bis-carbamate.
