Topoisomerase I inhibitor 2_product_DataBase

Bioactivity	Topoisomerase I inhibitor 2 (ZML-8) is a highly selective inhibitor of DNA topoisomerase I (Top1). Topoisomerase I inhibitor 2 inhibits Top1 activity and results DNA damage. Topoisomerase I inhibitor 2 blocks G2/M phase and induces apoptosis, exhibits anti-tumor effect[1].
Invitro	Topoisomerase I inhibitor 2 (ZML-8) (24 hours) exhibits strong inhibition with an IC50 value of 0.58 μM towards HepG2 and selective activity with SI values (selectivity index) of 55.70% between HepG2 and normal human liver cell line L-02[1].Topoisomerase I inhibitor 2 (1.25, 2.5 μM, 48 hours) inhibits tumor cells proliferation by decreasing anti-apoptotic expression of Bcl-2 and enhancing caspase-dependent apoptosis[1].Topoisomerase I inhibitor 2 (1.25, 2.5 μM, 48 hours) decreases Top1 specific activity and results in DNA damage by causing supercoiled DNA[1].
