| Bioactivity | Topoisomerase I inhibitor 5 is an effective topoisomerase inhibitor with IC50 value of. Topoisomerase I inhibitor 5 can interfere with DNA and significantly inhibit the activity of Topoisomerase I. Topoisomerase I inhibitor 5 can arrest cell cycle at the G1 phase and induce MCF-7 cells apoptosis. Topoisomerase I inhibitor 5 has potency in reversing P-gp-mediated resistance to Adriamycin[1]. |
| Invitro | Topoisomerase I inhibitor 5 (compound 14) (0-50 μM; 48 hours) exhibits antiproliferation activity against cancer cell lines and lower cytotoxicity in normal cells[1].Topoisomerase I inhibitor 5 (2-8 μM; 24 hours) induces MCF-7 cell cycle arrest at the G1 phase[1].Topoisomerase I inhibitor 5 (2-8 μM; 48 hours) increases the apoptotic rate of MCF-7/ADR and MCF-7 cells[1].Topoisomerase I inhibitor 5 (1.5-6 μM; 24 hours) increases the expression degree of cleaved-caspase-3 and cleaved-PARP in MCF-7; down-regulates the level of anti-apoptotic protein, up-regulates the levels of pro-apoptotic proteins in MCF-7/ADR[1].Topoisomerase I inhibitor 5 (0.1 μM; 24 hours) induces cell apoptosis by promoting the accumulation of ROS in MCF-7/ADR cell[1].Topoisomerase I inhibitor 5 (10 μg/ml; 24 hours) increases the accumulation of the ADR and Rh123 in MCF-7/ADR cells[1].Topoisomerase I inhibitor 5 (5, 10 and 20 μM; 24 hours) reduces the expression degree of P-gp by 14.95% and 18.10% in MCF-7/ADR cells at 10 and 20 μM[1].
