Inhibitor Comments
Note that pazopanib is a multi-target kinase inhibitor. See [30] for additional data.
Vandetanib also inhibits EGFR and RET tyrosine kinases, as well as VEGFR2.
Although LY2874455 has equipotent IC50s for FGFRs and VEGFR2 in biochemical assays, in vivo efficacy appears to be 6-9-fold less for VEGFR2 phosphorylation in mouse heart muscle compared to inhibition of FGFR phosphorylation [79].
