Description

General description

Cell-permeable. The naturally-occuring active ingredient from the herbal medicine, Eclipta alba, that acts as a selective and irreversible inhibitor of IKKα and IKKβ kinase activities (IC₅₀<10 µM). Inhibits NF-κB-mediated gene transcription in cells by blocking the phosphorylation and degradation of IκBα. Does not affect the activities of p38 MAP kinase or Akt.

The naturally isolated active ingredient of the herbal medicine, Eclipta alba, that acts as a cell permeable, selective and irreversible inhibitor of IKKα and β kinase activity (IC₅₀<10 µM). Inhibits NF-κB-mediated gene transcription in cells by blocking the phosphorylation and degradation of IκBα. Has no effects on p38 MAP kinase or Akt.
