Inhibition of cell proliferation in U87 and U87-TxR cell lines. Flow cytometric profiles of CFSE staining after 72 h treatment with 2 μM 5 and 8 μM 6. CFSE fluorescence declines following each cell division. Red-line areas indicate controls, while gray and black areas signify treated cells. Experiments were performed three times (n = 3).
