    Product Description

    KRN 633 is an ATP-competitive inhibitor of VEGFR kinase activity (IC50s = 170, 160, and 125 nM for VEGFR1, 2, and 3, respectively).1 At higher concentrations KRN 633 inhibits PDGFR-α and c-KIT with IC50 values of 0.97 and 4.3 μM, respectively, and is inactive towards a panel of 17 additional kinases.1 KRN 633 suppresses VEGF-dependent activation of MAPK and cell proliferation and demonstrates antitumor and antiangiogenic activity by inhibiting vessel formation and vascular permeability in human tumor xenograft models.2

    WARNING This product is not for human or veterinary use.
