Anti-Trypanosoma cruzi activity of extracts from Argentinean Asteraceae species
Authors
Abstract:
The anti-Trypanosoma cruzi activity of extracts from 13 Argentinean Asteraceae species was determined. Dichloromethane and methanol extracts of Acmella bellidioides, Aspilia silphioides, Viguiera tuberosa, Calyptocarpus biaristatus, Hyalis argentea, Helenium radiatum, Gaillardia megapotamica, Verbesina subcordata, Gymnocoronis spilanthoides, Viguiera anchusaefolia, Thelesperma megapotamicum, Zexmenia buphtalmiflora and Vernonia plantaginoides were evaluated in vitro against Trypanosoma cruzi epimastigotes. A. silphioides, V. tuberosa, V. subcordata, G. spilanthoides, G. megapotamica, T. megapotamicum and Z. buphtalmiflora dichloromethane extracts showed trypanocidal activity with inhibitions higher than 60% at a concentration of 10 µg/mL. The methanol extracts of H. radiatum and G. megapotamica were the most active with inhibitions of 70.1 and 77.7%, respectively at 10 µg/mL. The chromatographic profiles of the most active extracts showed bands and major peaks that could be attributed to flavonoids and terpenoid compounds.

The aim of this study was to investigate anti-bacterial activities and phytochemical composition of three Asteraceae (C. americanum, E. alba and V. colorata) from traditionally medicine of Burkina Faso. Inhibition zone diameters of extracts and minimum inhibitory concentration (MIC) of Gramnegative and Gram-positive strains were determinate using standard methods. Preliminary phytochemical test...

Inhibition of Trypanosoma brucei and Leishmania spp. sirtuins has shown promising antiparasitic activity, indicating that these enzymes may be used as targets for drug discovery against trypanosomatid infections. In the present work we carried out a virtual screening focused on the C pocket of Sir2 from Trypanosoma cruzi. Using this approach, the best ligand found was nicotinamide. In vitro tes...

Chagas disease is a so-called "neglected disease" and endemic to Latin America. Nifurtimox and benznidazole are drugs that have considerable efficacy in the treatment of the acute phase of the disease but cause many significant side effects. Furthermore, in the Chronic Phase its efficiency is reduced and their therapeutic effectiveness is dependent on the type of T. cruzi strain. For this reaso...

The trypanocidal action of green tea catechins against two different developmental stages of Trypanosoma cruzi is reported for the first time. This activity was assayed with the nonproliferative bloodstream trypomastigote and with the intracellular replicative amastigote parasite forms. An ethyl acetate fraction from Camellia sinensis green tea leaves, which contains most of the polyphenolic co...

Background: Some of medicinal plants are a potential source of new drugs to improve the treatment of Chagase disease whose treatment is still a challenge. Here in this screening, the in vitro trypanocidal activity of some fractions for 16 medicinal plants, collected from the northern part of Iran, has been reported. Methods: Aerial parts of the plants were dried carefully and followed by ex...
