SU 6668 is an ATP-competitive PDGFR, Flk-1/KDR and FGFR inhibitor (IC50 values are 0.06, 2.43, 3.04 and > 100μM at PDGFRβ, Flk-1/KDR, Flg/FGFR1 and EGFR respectively). SU 6668 inhibits proliferation of HUVEC and NIH3T3 cells in vitro (IC50 values are 0.41, 9.3 and 16.5 μM for Flk-1/KDR, FGF and PDGF-stimulated growth respectively) and induces > 75% growth inhibition against a broad range of tumor types. SU 6668 shows antiangiogenic, anti-inflammatory, antimetastatic and proapototic activity.
