OBJECTIVES: Aim of the present study was to evaluate the in vitro cytotoxic potential of the diosmin in A431 skin cancer cells.

MATERIALS AND METHODS: The cytotoxic (anti-cell proliferative) potential of diosmin in A431 cells was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay (cell viability), dual staining (apoptotic induction), dichloro-dihydro-fluorescein diacetate assay (reactive oxygen species [ROS] generation), DNA fragmentation study, Western blotting analysis (apoptotic markers expression) and flow cytometry (cell cycle arrest).

RESULTS: Diosmin reduced the cell viability of A431 cells in a dose-dependent fashion and the inhibitory concentration 50% value was attained at 45μg/ml using MTT assay. Diosmin at a concentration of 45 μg/ml generated excessive ROS in A431 cells, as compared to untreated cells. Diosmin treated A431 cells also revealed multiple DNA fragments than the untreated cells. Diosmin upregulated the expression of p53, caspases 3 and 9 and downregulated the expression of Bcl-2, matrix metalloproteinases-2 and 9 in A431 cells.

CONCLUSION: The cytotoxic or anti-cell proliferative potential of diosmin is due to its ROS-mediated apoptotic induction potential, as well as due to its role in the inhibition of invasion in the A431 cells.
