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.

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.
