Orantinib (SU-6668) is an orally bioavailable receptor tyrosine kinase inhibitor. Orantinib binds to and inhibits the autophosphorylation of vascular endothelial growth factor receptor 2 (VEGFR2), platelet-derived growth factor receptor (PDGFR), and fibroblast growth factor receptor (FGFR), thereby inhibiting angiogenesis and cell proliferation. Orantinib also inhibits the phosphorylation of the stem cell factor receptor tyrosine kinase c-kit, often expressed in acute myelogenous leukemia cells. Orantinib was in phase II clinical trials for the treatment of breast cancer. It was also in phase III clinical trials for the treatment of hepatocellular carcinoma. However, this research was terminated in 2014. The compound was originally developed by Sugen (subsidiary of Pfizer). In 1998, a co-development agreement took place between Sugen and Taiho for the compound.

Sample Use Guides

Orantinib at 200 mg, twice per day, or placebo was given orally until TACE failure or unacceptable toxicity.
Route of Administration: Oral
Orantinib (SU-6668) inhibited PDGF-stimulated PDGFRb tyrosine phosphorylation in NIH-3T3 cells overexpressing PDGFRb at a minimum concentration of 0.03–0.1 uM. SU-6668 inhibited acidic FGF-induced phosphorylation of the FGFR1 substrate 2 (FRS-2) at concentrations of 10 uM and higher. However, SU-6668 had no detectable effect on epidermal growth factor-stimulated EGFR tyrosine phosphorylation in NIH-3T3 cells overexpressing EGFR at concentrations of up to 100 uM. Orantinib (SU-6668) inhibited VEGF-driven mitogenesis of HUVECs in a dose-dependent manner with a mean IC50 of 0.34 uM.
