Description

Nur77 antagonist 1(Compound ja) is a selective Nur77 antagonist(KDSPRNur77 = 91 nM). Nur77 antagonist 1 induces cancer cell apoptosis. ja displays excellent antitumor against triple-negative breast cancer (TNBC) cells[1].

IC50 & Target

Nur77/NR4A1

 

In Vitro

Nur77 antagonist 1(Compound ja), shows selectivity against tumor cells from different tissues, possesses highly selective antiproliferative activity toward all tested TNBC cell lines (IC50: 0.40 ± 0.03, 0.38 ± 0.08, 2.12 ± 0.15 for MDA-MB-231,HCC-1806, and BT549) compared to the human normal breast cell line (IC50: 48.01 ± 2.86 for MCF-10A)[1].
Nur77 antagonist 1 (0-2 μM, 6 h) induces MDA-MB-231-sictr cells apoptosis in a Nur77-dependent manner[1].
Nur77 antagonist 1 (0-5 μM, 6 h) induces Nur77-dependent cell-cycle arrest and apoptosis by mediating the TP53 phosphorylation pathway in MDA-MB-231 cells[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.
