Abstract: This technology includes a group of at least twenty-nine, diverse, commercially available compounds that are newly identified for activity against Giardia lamblia parasites. At least six of the candidate compounds, Bortezomib, Decitabine, Hydroxocobalamin, Amlexanox, Idarubicin, and Auranofin have pre-existing FDA approval for human use for other (non-Giardia) conditions. Another three compounds, Fumagillin, Nitarsone and Carbadox have preexisting approval for veterinary use for non-Giardia conditions. Additional active compounds identified include: Acivicin, Riboflavin butyrate, BTO-1, GW9662, Dinitroph-dfgp, Deserpidine, Tetramethylthiuram disulsulfide, Disulfiram, Mitoxantrone, Ecteinascidin 743, 17-allyaminogeldanamycin, Carboquone and Nocodazole. The anti-Giardial activity of these compounds presents a cost saving opportunity for the rapid development of new, better tolerated treatments for the most prevalent human intestinal parasite infection in the United States and the world.
