Identification of novel inhibitors of UDP-Glc 4'-epimerase, a validated drug target for african sleeping sickness

Abstract

Novel inhibitors of Trypanosoma brucei and mammalian UDP-Glc 4'-epimerase were identified by screening a small library of natural products and commercially available drug-like molecules. The inhibitors possess low micromolar potency against the T. brucei and human enzymes in vitro, display a degree of selectivity between the two enzymes, and are cytotoxic to cultured T. brucei and mammalian cells.
