Studies with Trypanosoma brucei and other protozoans suggest that, like for other nitrocontaining drugs, the nitroreductase (NTR) enzyme plays an important role in the bioactivation of fexinidazole resulting in generation of reactive amines and damage to DNA and proteins. The activity of fexinidazole and its metabolites (M1 and M2) is trypanocidal and appears to be concentration and time dependent. However, the precise mechanism by which fexinidazole and the two metabolites exhibit activity against T. brucei is not known.
