The results were generated from three independent experiments; each experiment was performed in triplicate.
The IC50 values were calculated using CalcySyn™ (USA) software.
The selectivity index (SI) was also calculated from the IC50 ratio of normal epithelial and cancerous (CL-6, Hep-2, HepG2) cells.
SI value indicates selectivity of the sample to the cell lines tested. Samples with SI value greater than 3 were considered to have high selectivity.
