Biological Activity

Description CDDO-Im (RTA-403) is an activator of nuclear factor erythroid 2–related factor 2 (Nrf2) and peroxisome proliferator-activated receptor (PPAR). CDDO-Im binds to PPARα and PPARγ with Ki of 232 nM and 344 nM, respectively. CDDO-Im inhibits inflammatory response and tumor growth in vivo.

Nrf2 [1] PPARα [1]

(Cell-free assay)
232 nM(Ki) 344 nM(Ki)
In vitro

CDDO-Im is highly active in suppressing cellular proliferation of human leukemia and breast cancer cell lines (IC50, 10–30 nM). In U937 leukemia cells, CDDO-Im also induces monocytic differentiation as measured by increased cell surface expression of CD11b and CD36. CDDO-Im has significant actions independent of PPAR transactivation.[2]
In vivo

CDDO-Im is a novel synthetic triterpenoid more potent than its parent compound (CDDO). In vivo, CDDO-Im is a potent inhibitor of de novo inducible nitric oxide synthase expression in primary mouse macrophages. Moreover, CDDO-Im inhibits growth of B16 murine melanoma and L1210 murine leukemia cells in vivo.[2]

Protocol (from reference)
