Description

Cirsilineol, a natural flavone compound, selectively inhibits IFN-γ/STAT1/T-bet signaling in intestinal CD4+ T cells. Cirsilineol has potent immunosuppressive and anti-tumor properties. Cirsilineol significantly ameliorates trinitro-benzene sulfonic acid (TNBS)-induced T-cell-mediated experimental colitis in mice[1].

In Vitro

Cirsilineol (0.1-10 μM; 96 hours) inhibits single mixed lymphocyte reaction and Concanava A-induced T-cell proliferation in a dose-dependent manner. Cirsilineol (10 μM) does not affect T lymphocyte's viability. The inhibition of cirsilineol (10 μM) on T-cell proliferation is not due to a cytotoxic activity[1].
Cirsilineol (1-10 μM; pretreatment for 3 hours) completely inhibits IFN-γ-induced Tyr701 phosphorylation of STAT1 and JAK2 activation[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.
