Abstract

Only a few drugs are available for chemotherapy of African trypanosomiasis and there is an urgent need for the development of new anti-trypanosomal agents. In this study, the anti-helminthic drug niclosamide was tested for its trypanocidal activity in vitro using culture-adapted bloodstream forms of Trypanosoma brucei brucei and Trypanosoma congolense. The concentrations of niclosamide to reduce the growth rate by 50% and to kill all cells were in the low- and mid micromolar ranges for T. b. brucei and T. congolense, respectively. The very low toxicity of niclosamide for mammals makes the compound interesting for drug development for African trypanosomiasis.
