体外研究 (In Vitro) | Topoisomerase I/II inhibitor 3 (compound 7) (0-100 μM) can insert into DNA and change the topology of DNA, cause DNA damage to a certain extent[1]. Topoisomerase I/II inhibitor 3 (0-4 μM, 24 h) inhibits HCC (hepatocellular carcinoma) cells proliferation in a dose-dependent manner, inhibits migration and invasion of LM9 and HuH7 cells by inhibiting the expression of MMP-9[1]. Topoisomerase I/II inhibitor 3 (0-14 μM, 48 h) significantly induces the apoptosis of LM9 and HuH7 cells, and induces mitochondrial dysfunction and ROS burst in a dose-dependent manner[1]. Topoisomerase I/II inhibitor 3 (0-7 μM, 48 h) reduces the expression of the inhibitory factor Bcl-2 and promotes the expression of mitochondria-dependent apoptosis-related proteins such as Bax, cytochrome C, cleaved-caspase-3 and cleaved-caspase-9; inhibits the phosphorylation of PI3K/Akt/mTOR signaling pathway[1].
Cell Proliferation Assay Cell Line: | HCC cells (HuH7 and LM9)[1] | Concentration: | 0, 0.5, 1, 2, and 4 μM | Incubation Time: | 24 h | Result: | Inhibited HCC cells proliferation in a dose-dependent manner, with IC50values of 2.10 μM (LM9) and 1.93 μM (HuH7), respectively, and dose-dependently inhibited the formation of cell colonies. |
Apoptosis Analysis Cell Line: | LM9 and HuH7 cells[1] | Concentration: | 0, 1.8, 3.5, 7, and 14 μM | Incubation Time: | 48 h | Result: | Significantly induced the apoptosis of LM9 and HuH7 cells in a concentration-dependent manner. |
Western Blot Analysis Cell Line: | LM9 and HuH7 cells[1] | Concentration: | 0, 1.8, 3.5, and 7 μM | Incubation Time: | 48 h | Result: | Reduced the expression of the inhibitory factor Bcl-2 and promoted the expression of mitochondria-dependent apoptosis-related proteins such as Bax, cytochrome C, cleaved-caspase-3 and cleaved-caspase-9; inhibited the phosphorylation of PI3K/Akt/mTOR signaling pathway. |

体内研究 (In Vivo) | Topoisomerase I/II inhibitor 3 (compound 7) (male Kunming mice, 0-400 mg/kg, IP, once) causes the mice in the 400 mg/kg group die, with the LD50between 250 and 400 mg/kg[1].
Animal Model: | Male Kunming mice (19-22 mg, 8 mice, 4 groups)[1] | Dosage: | 200, 250, 400 mg/kg (dissolved in 5% DMSO and castor oil) | Administration: | IP, once | Result: | Did not cause the mice in the 250 mg/kg and 200 mg/kg groups die after 2 weeks of administration, and caused the mice in the 400 mg/kg group die, with the LD50between 250 and 400 mg/kg. |
