XRF-1021

• Description:

  XRF-1021 is an orally active HIPK2 inhibitor (IC50 = 0.18 μM) . XRF-1021 reduces the expression of fibrotic markers in TGF-β1 stimulated NRK-49F and HK-2 cells, including Fibronectin, Collagen I and α-SMA. XRF-1021 blocks TGF-β, NF-κB, p53, Wnt/β-catenin, and Notch signaling. XRF-1021 reduces renal injury and fibrosis in vivo. XRF-1021 can be used for the research of chronic kidney disease[1].
