A set of 1,8-naphtalimides derivatives were synthesized and tested against three protozoans that cause important human diseases: Leishmaniainfantum, Trypanosomabrucei and Trypanosomacruzi. Additionally, toxicity was determined by growth inhibition of THP-1 derived macrophages. The results suggest that chemical modifications in the carbon chain linking the naphthalimide and the substituting groups have different effects in the parasites. This work should provide new insights for the design and optimization of more potent and directed naphthalimide derivatives against these organisms.
Keywords: Naphtalimides derivatives, anti-parasitic activity, cytotoxicity.
