Topoisomerase ll/ME-1-IN-1 (Compound 7a) is a Topoisomerase ll and ME-1 inhibitor with an IC50 of 5.03 μM against Topoisomerase ll. Topoisomerase ll/ME-1-IN-1 functionally inhibits the activity of Topoisomerase II and functionally blocks the activity of ME-1. Topoisomerase ll/ME-1-IN-1 induces Autophagy by upregulating the expression of Beclin-1 and LC3-II. Topoisomerase ll/ME-1-IN-1 promotes Apoptosis. Topoisomerase ll/ME-1-IN-1 exhibits antiproliferative activity against breast cancer cells and shows no toxicity to normal mammary epithelial cells. Topoisomerase ll/ME-1-IN-1 can be used in studies related to breast cancer (including triple-negative breast cancer).

IC50 & Target[1]

Topoisomerase II

5.03 μM (IC50)

In Vitro

Topoisomerase II/ME-1-IN-1 (48 h) potently inhibits the proliferation of MCF-7 and MDA-MB-231 breast cancer cells, with IC50 values of 3.1 ± 0.17 μM and 1.04 ± 0.07 μM, respectively, while exhibits low activity against normal MCF-10A cells[1].
Topoisomerase II/ME-1-IN-1 induces autophagy in MCF-7 and MDA-MB-231 cells by upregulating the expression of Beclin-1 and LC3-II, with the level of LC3-II in MDA-MB-231 cells reaching 1852.448 ± 48.193 ng/mg proteins[1].
Topoisomerase II/ME-1-IN-1 (at IC50 concentration) induces apoptosis in MCF-7 and MDA-MB-231 cells via the mitochondrial pathway, upregulates the expression of Bax, cleaved PARP-1 and caspase-9, downregulates the expression of Bcl-2, and causes cell cycle arrest; among these cells, the early apoptosis rate of MCF-7 cells is 24.61%, and that of MDA-MB-231 cells is 18.28%[1].
Topoisomerase II/ME-1-IN-1 potently inhibits topoisomerase II with an IC50 of 5.03 ± 0.163 μM[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
