* <1 mg/ml means slightly soluble or insoluble. * Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations. * Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity
Description
Fruquintinib is a small molecule inhibitor with strong potency and high selectivity against the VEGFR family. It inhibits VEGFR 1, 2, 3, with IC50 values of 33 nM, 35 nM and 0.5 nM, respectively and shows only weak inhibition of RET, FGFR-1 and c-kit kinases.
Targets
VEGFR3 (Cell-free assay)
VEGFR1 (Cell-free assay)
VEGFR2 (Cell-free assay)
0.5 nM
33 nM
35 nM
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 favourable 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-tumour efficacy in a number of human tumour xenograft models with good dose response.
Primary HUVEC cells at 2 × 104 cells/well were seeded in flat bottomed 96-well plates with 100 mL media containing 0.5% FBS. The next day, cells were treated with fruquintinib for 18 hours at 37 C. The cell survival was determined by AlamarBlue assay. The plates were incubated for 3 hours at 37 C and fluorescence value was read at Ex 530 nm and Em 590 nm on Tecan.
