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.

In vitro
In in vitro enzymatic and cellular assays, Fruquintinib inhibits VEGFR family kinases and suppressed VEGF/VEGFR cell signaling in human umbilical vein endothelial cell (HUVEC) and human lymphatic endothial cell (HLEC) with IC50 at low nanomolar level. Few kinases are inhibited other than VEGFRs in a panel of 253 kinases test. This compound is a highly potent inhibitor of VEGF-induced angiogenesis.
In vivo
Fruquintinib demonstrates favorable pharmacokinetic profile in multiple animal species, oral administration of this compound strongly suppressed VEGF-induced VEGFR2 phosphorylation in the lung tissue in mice. The extent and duration of the inhibition of VEGFR2 phosphorylation correlated well with drug exposures. The strong anti-angiogenic effect resulted in robust anti-tumor efficacy in a number of human tumor xenograft models with good dose response.
