Fig. 3. Representative graph comparing the percentage growth inhibition of HEK-293 cells at selected concentrations of test compounds 13f and 13g. 40 μM Plumbagin was used as a positive control. Data are mean ± standard deviation S.D (n = 3), where *p < 0.05, **p < 0.01 and ***p < 0.001 significant difference to untreated control.
