Abstract

Chagas disease is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi. It is estimated that 6 million people are infected in Latin America. Current treatment is not effective due to the severe side effects and the limited efficacy towards the chronic phase of the disease. Considering the growing need for specific anti-Trypanosoma cruzi drugs, organometallic Pt and Pd based compounds were previously synthesized. Although the Pt-based compound effects on T. cruzi death have been reported, no mechanism of action has been proposed for the Pd-based analogous compound. In this work, we determined excellent to very good values of IC50 and SI. To analyze the compound mode of action, we measured Pd uptake and its association to the macromolecules of the parasite by electrothermal atomic absorption spectrometry. We found a poor uptake, which reaches only 16% after 24 h of incubation using 10× IC50, being the scarce incorporated metal preferentially associated to DNA. However, this compound has a trypanocidal effect, leading to morphological changes such as shortening of the parasite cell body and inducing necrosis after 24 h of treatment. Furthermore, this compound impairs the parasite development in the host both at the trypomastigote infection process and the intracellular amastigotes replication. In conclusion, our findings support that Pd-dppf-mpo compound constitutes a promising anti-T. cruzi compound effective against the chronic phase of the disease.
