Sixteen methanolic extracts obtained from thirteen plant species, selected either from ethnobotanical or chemotaxonomical data, were screened for their antileishmanial activity against Leishmania amazonensis. The cytotoxic activity against normal peritoneal macrophages from normal BALB/c mice was also determined. Eight extracts had IC50 values ranging from <12.5 to 37.8 µg/mL against promastigo...
Leishmaniasis treatment is hampered by the increased appearance of treatment failure. ATP-binding cassette (ABC) transporters are usually involved in drug resistance both in tumor cells and in microorganisms. Here we report the characterization of an ABCG-like transporter, LiABCG6, localized mainly at the plasma membrane in Leishmania protozoan parasites. When overexpressed, this half-transport...
An orally delivered, safe and effective treatment for leishmaniasis is an unmet medical need. Azoles and the pyrazolylpyrimidine allopurinol present leishmanicidal activity, but their clinical efficacies are variable. Here, we describe the activity of the new pyrazolyltetrazole hybrid, 5-[5-amino-1-(4'-methoxyphenyl)1H-pyrazole-4-yl]1H-tetrazole (MSN20). MSN20 showed a 50% inhibitory concentrat...
Here we studied ability of two naphthoquinones to inhibit Leishmania growth (2,3-dichloro-5,8-dihydroxy-1,4-naphthoquinone (TR 001) and 2,3-dibromo-1,4-naphthoquinone (TR 002). TR 001 was more efficient than TR 002 in inducing killing of promastigotes and intracellular amastigotes. These values compare well to those obtained with the standard first-line antileishmanial agent sodium stiboglucona...
