Human African trypanosomiasis ( HAT) is caused by the protozoan parasite Trypanosoma brucei. The cysteine proteases of T. brucei have been shown to be crucial for parasite replication and represent an attractive point for therapeutic intervention. Herein we describe the synthesis of a series of thiosemicarbazones and their activity against the trypanosomal cathepsins TbcatB and rhodesain, as well as human cathepsins L and B. The activity of these compounds was determined against cultured T. brucei, and specificity was assessed with a panel of four mammalian cell lines. (c) 2008 Elsevier Ltd. All rights reserved.
