Biological Activity

Description

Apatinib (Rivoceranib, YN968D1) is a potent inhibitor of the VEGF signaling pathway with IC50 values of 1 nM, 13 nM, 429 nM and 530 nM for VEGFR-2, Ret (c-Ret), c-Kit and c-Src, respectively. Apatinib induces both autophagy and apoptosis.

Targets

VEGFR2 ^[1] (Cell-free assay)	RET ^[1] (Cell-free assay)
1 nM	13 nM

In vitro

Apatinib (YN968D1) potently suppressed the kinase activities of VEGFR-2, c-kit and c-src, and inhibited cellular phosphorylation of VEGFR-2, c-kit and PDGFRβ. YN968D1 suppress the activities of Ret, c-kit and c-src with an IC50 of 0.013 μM, 0.429 μM and 0.53 μM, respectively. YN968D1 had no significant effects on EGFR, Her-2 or FGFR1 in concentrations up to 10 μM. YN968D1 effectively inhibited proliferation, migration and tube formation of human umbilical vein endothelial cells induced by FBS, and blocked the budding of rat aortic ring^[1].

In vivo

In vivo,　YN968D1 alone and in combination with chemotherapeutic agents　effectively inhibited the growth of several established human　tumor xenograft models with little toxicity^[1].　

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines HUVEC Concentrations 0.1 and 1 μM Incubation Time 72 h Method The HUVEC were seeded into 96-well plates. After 24 h of incubation, cells were exposed to the test agents (vehicle as control) together with 20 ng ⁄mL VEGF or 20% FBS for another 72 h. After fixation with 10%　trichloroacetic acid, the cells were stained with 0.4% sulforhodamine B for 30 min at 37℃ and then washed with 1% acetic acid. Tris was added to dissolve the complex, and the optical density was measured at 520 nm.
Animal Study:^{^[1]}	Animal Models tumor xenograft model (NCI-H460 human lung tumors, HCT 116 human colon tumors, or SGC-7901 human gastric tumors; BALB⁄cA nude mice) Dosages 50, 100 and 200 mg/kg Administration by oral gavage
