生物活性

Topoisomerase IIα-IN-4 (F2) is a non-intercalative ATP-competitive human DNA topoisomerase II inhibitor with an IC50 value of 3.8 and 10.1 μM for TopoIIα and TopoIIβ, respectively. Topoisomerase IIα-IN-4 shows potent potency in apoptosis induction and cell cycle arrest in HepG2 cells. Topoisomerase IIα-IN-4 exhibits strong antitumor activities against human cancer cell lines, it can be used for the research of cancer[1].

体外研究
(In Vitro)

Topoisomerase IIα-IN-4 (0-50 μM; 72 h) shows antiproliferative activities against cancer cells[1].
Topoisomerase IIα-IN-4 shows high inhibitory activity and subtypeselectivity against TopoIIα and β with IC50s of 3.8 and 10.1 μM, respectively[1].
Topoisomerase IIα-IN-4 (0.3 μM; 4 h) is a non-intercalative TopoIIα catalytic inhibitor[1].
Topoisomerase IIα-IN-4 (0.5-1 μM; 48 h) induces cell apoptosis[1].
Topoisomerase IIα-IN-4 (0.5-1 μM; 24 h) induces cell-cycle arrest[1].

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.
