Fluorinated derivatives of radicamine A and radicamine B have been synthesized from D-arabinose-derived cyclic nitrone. Structure-activity relationship studies showed that glycosidase inhibition of these fluorinated derivatives was significantly influenced by the position of the fluorine atom. C-7 or C-11 fluorination of the aromatic ring decreased alpha-glucosidase inhibition of the derivatives, whereas C-8 or C-10 fluorination preserved glycosidase inhibitory activities.
