| Resumen en inglés | The trypanosomatids Trypanosoma brucei, Trypanosoma cruzi and Leishmania spp. are etiological agents of important neglected tropical diseases, affecting millions of people worldwide, and the drugs available for these diseases present several limitations. Novel efficient and nontoxic drugs are necessary as an alternative to the current chemotherapy. The unique mitochondrion of trypanosomatids and its peculiar features turn this organelle a potential drug target. Several phenotypic studies describe the damage in the parasite mitochondrial ultrastructure, but the molecular target is unknown. Few reports demonstrated the electron transport system (ETS) as a target due to the high similarities to mammalian orthologues, hence ETS is not a good candidate for drug intervention. On the other hand, antioxidant enzymes, such as trypanothione reductase, and an alternative oxidase (AOX) seem to be interesting targets; however no high active inhibitors were developed up to now. Finally, due to the remarkable differences to mammalian machinery, together with the high biological importance for the parasite survival, the mitochondrial import system stands out as a very promising target in trypanosomatids. Archaic translocase of the outer membrane (ATOM) and translocase of the inner membrane (TIM) complexes, which mediate both protein and tRNA import, composed by specific subunits of these parasites, could be excellent candidates, deserving studies focused on the development of specific drugs |
