We aimed to explore the cytotoxic and apoptotic effect of friedelin on breast cancer MCF-7 cells. Cytotoxic effect of friedelin on MCF-7 cells was analyzed using MTT, cell and nuclear morphology. The apoptosis mechanism of friedelin on MCF-7 cells was analyzed using real-time PCR. Friedelin potentially inhibit 78% of MCF-7 cell's growth, the IC50 value was 1.8 μM in 24 h and 1.2 μM in 48 h. Friedelin increased ROS significantly and DNA damage was confirmed by tunel assay. We found characteristically 52% apoptotic cells and 6% necrotic cells in PI, AO/ErBr staining after 48 h treatment with 1.2 μM of friedelin. Apoptosis was confirmed by significantly (p â¤Â 0.001) increased tumor suppressor gene Cdkn1a, pRb2, p53, Nrf2, caspase-3 and decreased Bcl-2, mdm2 & PCNA expression after 48 h. In conclusion, friedelin effectively inhibit breast cancer MCF-7 cell growth, it was associated with early expression of Cdkn1a, pRb2 and activation of p53 and caspases.
