生物活性:
Topoisomerase I/II inhibitor 4 (compound F16) is a potent topoisomerase I (Topo I) and II (Topo II) dual inhibitor. Topoisomerase I/II inhibitor 4 inhibits cell proliferation, invasion and migration and induces apoptosis. Topoisomerase I/II inhibitor 4 can be used for liver cancer research.

体内研究:
Topoisomerase I/II inhibitor 4 (compound F16) (10-50 mg/kg; i.v.; per 2 days, for 7 days) suppresses tumor growth in the A375 Xenograft Model.Topoisomerase I/II inhibitor 4 (compound F16) of the plasma clearance rate (CL) was 7-fold lower than that of VP-16(0.007 L/min/kg). Topoisomerase I/II inhibitor 4 has a delayed elimination half-life of 151 min.Animal Model:Female BALB/c nude mice (5?6 weeks)

体外研究:
Topoisomerase I/II inhibitor 4 (compound F16) (0-100 μM) could intercalate into DNA to inhibit enzymatic activity and inhibit Topo I and II activities in a dose-dependent manner.Topoisomerase I/II inhibitor 4 (compound F16) shows a high-expression level of Topo I and II enzymes in A375 and HCT116 cells and exhibits potent anti-proliferative activity with IC50 values of 20 and 50 nM, respectively, 10-fold lower than L02.Topoisomerase I/II inhibitor 4 (compound F16) (0-40 nM, A375 cell) inhibits cancer cell colony formation, invasion, migration and induces cell apoptosis.
