Topo I/II-IN-3
Topo I/II-IN-3 is a dual inhibitor of topoisomerase I/II (topoisomerase I/II), with an IC50 of 8.99 μM against Topo I and an IC50 of 26.92 μM against Topo II. Topo I/II-IN-3 induces DNA damage, elevates intracellular ROS levels, activates the mitochondrial apoptosis pathway, and exerts cytotoxicity against cancer cells. Topo I/II-IN-3 upregulates the expression of γ-H2AX, p53, activated caspase-9, Bax and activated caspase-3, while downregulating the expression of Bcl-2. Topo I/II-IN-3 can be used in research related to breast cancer, liver cancer and gastric cancer.

Topo I/II-IN-3 (Compound A6) (0.6-22.1 μM; 48 h) potently inhibits the proliferation of MCF-7, MDA-MB-231, HepG2 and SGC-7901 cancer cells, with IC50 values of 0.6, 12.6, 3.4 and 5.4 μM, respectively, and exhibits low cytotoxicity against normal HEK-293 cells (IC50 = 22.1 μM)[1].
Topo I/II-IN-3 (1.56-100 μM; 30 min) blocks DNA relaxation and kDNA decatenation, with IC50 values of 8.99 μM and 26.92 μM, respectively[1].
Topo I/II-IN-3 (0.3-1.2 μM; 24 h) induces dose-dependent DNA damage in MCF-7 cells, upregulates the expression of γ-H2AX, and increases the levels of p53, activated caspase-9, Bax and activated caspase-3, while downregulating Bcl-2[1].
Topo I/II-IN-3 (0.25-1 μM; 24-48 h) potently inhibits the long-term proliferation and migration of MCF-7 cells[1].
Topo I/II-IN-3 (0.3-1.2 μM; 24 h) induces dose-dependent G2/M phase arrest, triggers apoptosis, elevates intracellular ROS levels, and reduces mitochondrial membrane potential in MCF-7 cells[1].
