AIM: To study the antitumor effects of curcin from Jatropha curcas. METHODS: Antitumor activity of curcin was tested by MTT assay. The N-glycosidase activity of curcin was determined by characterization of R-fragment in gel. A cell-free system, rabbit reticulocyte lysate, was introduced to quantify the inhibitory activity of curcin on protein biosynthesis. RESULTS: The curcin had a powerful inhibitory action upon protein synthesis in reticulocyte lysate with an IC_(50) (95% confidence limits) value of 0.19 ...
