Leishmaniasis and bioinorganic compounds containing Au(I) and Pd(II): antileishmanial activities, mechanims of action and putative new drug targets

Abstract

The World Health Organization (WHO) estimates that more than one billion people suffer from neglected tropical diseases. Leishmaniasis is a widespread disease, affecting 12 million people around the world with about 1-2 million estimated new cases occurring every year. For more than 60 years, pentavalent antimonials, Sb (V) compounds, have been the first-line chemotherapy against leishmaniasis, but the emergence of resistant strains has limited their usefulness. Alternatively, amphotericin B, pentamidine isethionate, miltefosine and paramomycin are available, but their use is limited due to toxicity or high cost of treatment. The main goal of this proposal is to evaluate in vitro and in vivo leishmanicidal activities of bioinorganics compounds containing gold(I) or palladium(II). Besides, investigate possible mechanisms of action of such compounds through proteomics, metalomics and genetics approaches are also been considered. (AU)
