体外研究:
Topoisomerase II inhibitor 4 (compound E17) inhibits cancer cells with IC50 values of 4.55 μM (MDA-MB-231), 6.61 μM (A549), 2.18 μM (KG1).Topoisomerase II inhibitor 4 (1 μM; 0-22 h) induces G2/M cell cycle arrest.Topoisomerase II inhibitor 4 (5 μM; 4 h) inhibits topo II-mediated chromosomes condensation in CRC cells, while also (100 μM; 0.5, 1, 2 h) induces topo II–DNA complex accumulation without degradation of topo II.Topoisomerase II inhibitor 4 (1 μM; 4 h) exerts anti-tumor activity without increasing gH2AX levels in HCT116, while no DNA damage and apoptosis as well .
