Biological Activities of Extracts from Ageratum fastigiatum: Phytochemical Study and In Silico Target Fishing Approach.

In the present study, the ethanolic extract from aerial parts of was evaluated against epimastigote forms of (Y strain), promastigote forms of (PH8 strain), and (BH400 strain). The extract was also evaluated against (ATCC 25 923), (ATCC 11 775), (ATCC 10 145), and (ATCC 36 802). The phytochemical screening was performed by thin-layer chromatography and high-performance liquid chromatography.

pharmacological prediction and cytotoxicity of flavonoids glycosides identified by UPLC-DAD-ESI-MS/MS in extracts of leaves cultivated in Brazil.

Ethanolic (EB) extract and hexanic (SH) and hydromethanolic (SEM) sub-extracts of leaves were submitted to cytotoxicity evaluation and to phytochemical methods. The effect of EB and SEM on cellular cycle was evaluated by propidium iodide method and the phases were quantified through flow cytometry. The cytotoxicity assessment was done using T24 and MRC5 cells, with EB and SEM (25-1200 µg/mL).

Upregulation of Cardiac IL-10 and Downregulation of IFN- in Balb/c IL-4 in Acute Chagasic Myocarditis due to Colombian Strain of .

Inflammatory response in Chagas disease is related to parasite and host factors. However, immune system regulation has not been fully elucidated. Thus, this study is aimed at evaluating IL-4 influence on acute phase of experimental infection through dosage of cytokine levels in cardiac homogenate of infected Balb/c WT and Balb/c IL-4 as well as its histopathological repercussions.

Combined In Vitro Studies and in Silico Target Fishing for the Evaluation of the Biological Activities of and .

This paper reports the in silico prediction of biological activities of lignans from and combined with an in vitro bioassays. The extracts from the leaves, roots and rhizomes of both species were evaluated for their antibacterial, anticholinesterasic, antioxidant and cytotoxic activities. A group of 27 lignans was selected for biological activities prediction using the Active-IT system with 1987 ligand-based bioactivity models.

Aspidosperma species: A review of their chemistry and biological activities.

Ethnopharmacological Relevance: Species of Aspidosperma are known popularly as "peroba, guatambu, carapanaúba, pau-pereiro" and "quina". The genus can be found in the Americas, mainly between Mexico and Argentina. Many species of Aspidosperma are used by the population in treating cardiovascular diseases, malaria, fever, diabetes and rheumatism.

Biological activities of extracts from Aspidosperma subincanum Mart. and in silico prediction for inhibition of acetylcholinesterase.

Species of Aspidosperma are traditionally used to treat malaria, leishmaniasis, microbial, and inflammatory diseases. Aspidosperma subincanum Mart. known as "guatambu" is used in Brazilian traditional medicine to treat diabetes, hypercholesterolemia, and digestive diseases.

Antigenotoxic prenylated flavonoids from stem bark of Erythrina latissima.

A series of prenylated flavonoids was obtained from antigenotoxic extracts and fractions of stem bark of Erythrina latissima E. Mey (Leguminosae). In addition to five constituents never reported before, i.

Screening of Brazilian medicinal plants for antiviral activity against rotavirus.

Ethnopharmacological Relevance: Brazilian medicinal plants traditionally used for the treatment of diarrhoea were investigated for their in vitro antiviral activity against the simian rotavirus SA11.

Materials And Methods: The ethanolic crude extracts of plants collected in the cerrado of Minas Gerais, Brazil were submitted to phytochemical screening. The cytotoxicity of the extracts was inferred by cellular morphologic alterations.
