Herein, we describe the synthesis of a new series of pyrrolidine-ferrocene conjugates, consisting of a L-fuco-configured dihydroxypyrrolidine as the fucosidase ligand armed with a cytotoxic ferrocenylamine moeity. Three-dimensional structures of several of these fucosidase inhibitors reveal transition-state-mimicking (3)E conformations. Elaboration with the ferrocenyl moiety results in sub-micromolar inhibitors of both bovine and bacterial fucosidases, with the 3D structure of the latter revealing electron density indicative of highly mobile alkylferrocene compounds. The best compounds show a strong antiproliferative effect, with up to 100% inhibition of the proliferation of MDA-MB-231 cancer cells at 50 muM. alpha-L-fucosidase inhibition by pyrrolidine-ferrocene hybrids: rationalization of ligand-binding properties by structural studies.,Hottin A, Wright DW, Steenackers A, Delannoy P, Dubar F, Biot C, Davies GJ, Behr JB Chemistry. 2013 Jul 15;19(29):9526-33. doi: 10.1002/chem.201301001.
