Methods U87 cells were cultured for 24 h in the medium which contained AG1478 with different concentrations (0, 5, 10, 15, 20 μmol/L). The methyl thiazolyl tetrazolium(MTT) assay was used to detect the survival rate, and the cells cycle and apoptosis of the cells were examined by using flow cytometry. Results The cells proliferation was obviously inhibited by AG1478 in a dose-dependent manner. The survival rate of the cells in 5, 10, 15, 20 μmol/L AG1478 groups was (78.93 ±11.95)%, (46.42 ±4. 12)%, (42. 13 ±7.54)% and (37.48 ±4.69)% respectively, which was all significantly higher than that in 0 μ mol/L AG1478 group (P <0. 05 ). The apoptotic rate in 10, 25μmol/L AG1478 groups was (32.02 ± 1.60)% and (54. 35 ± 2. 80)% respectively, significantly higher than that in 0 μmol/L AG1478 group ( P < 0. 05 ). The cells cycle was obviously inhibited by AG1478 in a dose-dependent manner. The percentage of cells treated with 10 and 20 μmol/L AG1478 in Go-G1 phase was ( 78. 61 ± 1.57 ) % and ( 82. 73 ± 0. 77 ) % respectively, significantly higher than that in 0 μmol/L AG1478 group (P < 0. 05 ). Conclusion The growth inhibition of glioma U87 cells caused by AG1478 may be associated with apoptotsis induction and the G0-G1 arrest. AG1478 was expected to become a new anti-tumor drug in human glioma.
