Effects of RF-Id (a), RF-Idmet(b) and embelin(c) on cell growth inhibition. Human GBM cells U87MG and LN229 were seeded in serum-containing media in 96-well plates at the density of 2 × 103 cells/well. After 24 h incubation at 37 °C, cells were treated with increasing concentrations of RF-Id (a), RF-Idmet (b) and embelin (c) (0,8–100 μM) for 72 h. Cell viability was assessed by MTT assay as described in Material and methods. ** p ≤ 0.01
