Apatinib (formerly known as Rivoceranib, YN-968D1) is a potent, orally bioavailable, and selective inhibitor of the VEGF (vascular endothelial growth factor receptor) signaling pathway with potential antiangiogenic and antineoplastic activities. With an IC50 of 1 nM, it inhibits VEGFR2. The Chinese FDA (CFDA) approved apatinib (marketed as Itan® in China) in December 2014 for the treatment of gastric carcinoma in a late stage. In addition to inhibiting cellular phosphorylation of VEGFR-2, c-kit, and PDGFRβ, apatinib potently suppressed the kinase activities of VEGFR-2, c-kit, and c-src. In addition to blocking the budding of rat aortic rings, apatinib effectively inhibited the proliferation, migration, and tube formation of human umbilical vein endothelial cells induced by FBS. Apatinib efficiently and minimally harmed the growth of multiple well-established human tumor xenograft models in vivo, both when used alone and in conjunction with chemotherapeutic drugs.

Apatinib (YN968D1) exhibited a potent kinase suppression effect on VEGFR-2, c-kit, and c-src, as well as an inhibition of cellular phosphorylation of VEGFR-2, c-kit, and PDGFRβ. With an IC50 of 0.013 μM, 0.429 μM, and 0.53 μM, respectively, YN968D1 suppresses the activities of Ret, c-kit, and c-src. At concentrations up to 10 μM, YN968D1 did not significantly affect EGFR, Her-2, or FGFR1. In addition to blocking the budding of rat aortic ring, YN968D1 efficiently suppressed the proliferation, migration, and tube formation of human umbilical vein endothelial cells stimulated by FBS[1].

| Enzyme Assay |
Apatinib, also known as YN968D1, is a newly developed selective inhibitor that can be taken orally and may have antiangiogenic and antineoplastic properties. Apatinib inhibits VEGFR2 by binding to it specifically. Apatinib also has a potent inhibitory effect on Ret, c-kit, and c-src activity, with IC50 values of 0.013 M, 0.429 M, and 0.53 M, respectively. Apatinib prevents PDGFRβ, c-kit, and VEGFR-2 from becoming phosphorylated in cells. Proliferation induced by 20 ng/mL VEGF is significantly inhibited by atainib (IC50 = 0.17μM).

| Cell Assay |
In 96-well plates, the HUVEC were seeded. After incubating for 24 hours, the test agents (vehicle serving as the control) were added to the cells, along with 20 ng ⁄mL VEGF or 20% FBS, and left them for an additional 72 hours. The cells were first fixed with 10% trichloroacetic acid, then stained for 30 minutes at 37°C using 0.4% sulforhodamine B. Afterward, they were cleaned with 1% acetic acid wash. 520 nm optical density was measured after the complex was dissolved with the addition of Tris.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
