Infections by protozoans of the genus Leishmania are the major worldwide health problem, with high endemicity in developing countries. The drugs of choice for the treatment of leishmaniasis are the pentavalent antimonials, which exert renal and cardiac toxicity. Thus, there is a strong need for safer and more effective treatments against leishmaniasis. The(More)
The natural biflavonoids morelloflavone-4‴-O-β-D-glycosyl (1), (±)-fukugiside (2) and morelloflavone (3) were isolated from the ethyl acetate extract (EAEE) of dried and powdered fruit epicarps of Garcinia brasiliensis and derivatives of morelloflavone were semi-synthesised. Morelloflavone-7,4',7″,3‴,4‴-penta-O-acetyl (4),(More)
The 70 kDa heat shock protein (HSP70) is a molecular chaperone that assists the parasite Leishmania in returning to homeostasis after being subjected to different types of stress during its life cycle. In the present study, we evaluated the effects of HSP70 transfection of L. amazonensis promastigotes (pTEX-HSP70) in terms of morphology, resistance,(More)
The leishmaniasis, considered a neglected disease, is caused by a protozoan from the genus Leishmania. There is an urgent need to search for safer, cheaper, and more effective treatments against leishmaniasis. In this context, transition metal complex activities have been studied, as palladium, which has become an interesting alternative as metal-based(More)
