Description

Topo I-IN-1 (Compound 14d) is a potent Topo I inhibitor with antitumor activity and DNA intercalative capability. Topo I-IN-1 induces cell apoptosis^[1].

IC₅₀ & Target

Topoisomerase I

In Vitro

Topo I-IN-1 (Compound 14d) (0-50 µM, 48 h) shows antiproliferative activity against human cancer cells and has low toxicity toward normal rat kidney epithelial cells^[1].
Topo I-IN-1 (0-4 µM, 48 h) shows a dose-dependent apoptotic effect, induces ROS generation, and inhibits cell migration^[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.
