• 产品描述： Fruquintinib (HMPL-013) is a small molecule inhibitor with strong potency and high selectivity against 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.

• 靶点： VEGFR3(Cell-free assay):0.5 nM; VEGFR1(Cell-free assay):33 nM; VEGFR2(Cell-free assay):35 nM;VEGFR

• 体外研究：
  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. Fruquintinib is a highly potent inhibitor of VEGF-induced angiogenesis

• 体内研究：
  Fruquintinib demonstrates favorable pharmacokinetic profile in multiple animal species, oral administration of fruquintinib 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

• 细胞实验： Cell lines: Primary HUVEC cells Concentrations: 0.005, 0.05, 0.5 μM Incubation Time: 18 hours Method: 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.

• 动物实验： Animal Models: Female Balb/c nude mice at the age of 10-11 weeks Dosages: 2.5 mg/kg Administration: oral
