Stilbenes are compounds found in numerous medicinal plants and food products with some known biological and even antileishmanial activity. This paper describes the preparation of Aza-stilbene derivatives and their in vitro biological activities against Leishmania species. Most of the compounds with hydroxyl groups (2a, 2b, 2d, 2e and 2f) showed interesting(More)
Enterococci are one of the usual residents of the microflora in humans. In the last decade this genus has been reported as the third most common cause of bacteremia. We present the case of a 78-year-old female who was admitted to the emergency room because of nausea, lipothymia, and weakness. She was diagnosed with a pyelonephritis with bacteremia, with the(More)
Synthesis, characterization, DFT studies and biological assays of new gold(I) and gold(III) complexes of benzimidazole are reported. Molecular and structural characterizations of the compounds were based on elemental (C, H and N) and thermal (TG–DTA) analyses, and FT-IR and UV–Visible spectroscopic measurements. The structures of complexes were proposed(More)
In our previous work, we demonstrated the promising in vitro effect of VOSalophen, a vanadium complex with a stilbene derivative, against Leishmania amazonensis. Its antileishmanial activity has been associated with oxidative stress in L. amazonensis promastigotes and L. amazonensis-infected macrophages. In the present study, the mechanism involved in the(More)
