Apatinib

Synonyms: Rivoceranib, YN968D1

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.

(Cell-free assay)
1 nM 13 nM
In vitro
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].
Cell Research 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.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
