Target	Topoisomerase I
In Vitro	Topoisomerase I inhibitor 8 (compound 57) shows antitumor activities against three cell line cultures with IC50s of 0.22 ng/mL (P388), 2.06 ng/mL (HOC-21), 0.17 ng/mL (QG-56), respectively[1]. Topoisomerase I inhibitor 8 results the change in DNA from the supercoiled form to the relaxed form in the presence of topoisomerase I, shows stronger effective than SN-38 (HY-13704), with IC50 of compound/IC50 of SN-38=0.51[1].
