Publication Abstract from PubMed
Enhanced metabolism of fucose through fucosidase overexpression is a signature of some cancer types, thus suggesting that fucosidase-targetted ligands could play the role of drug-delivery vectors. 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.
