Trans-Resveratrol Induces Apoptosis through ROS-Triggered Mitochondria-Dependent Pathways in A549 Human Lung Adenocarcinoma Epithelial Cells.

Resveratrol has been shown to be a potential chemopreventive and anticancer agent, inducing apoptosis in a variety of cancer cells. The present study was performed to evaluate the effect of resveratrol on A549 human lung adenocarcinoma epithelial cells. 3-(4,5-Dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide evaluation demonstrated that the exposure of cells to increasing concentrations of resveratrol (0-175 µM) for 24 h resulted in a decrease in cell viability (IC50 85.

In vitro antileishmanial activity of resveratrol originates from its cytotoxic potential against host cells.

In addition to a range of beneficial pharmacological activities, resveratrol is recently reported to have potential antileishmanial activities in vitro. The present study was conducted to evaluate the effect of resveratrol on promastigotes and amastigotes of transgenic Leishmania major expressing green fluorescent protein in comparison with its direct cytotoxic effects on host cells (bone marrow-derived and J774-G8 macrophages, respectively). As assessed by FACS analysis, resveratrol showed moderate antipromastigote activity at <35 µg/mL (153.
