In vitro
BIBF 1120 (Vargatef), a novel, oral, triple angiokinase inhibitor, is targeting three receptor classes including VEGFR, PDGFR and FGFR which are all involved in blood vessel formation. BIBF 1120 binds to the ATP-binding site in the cleft between the NH2 and COOH terminal lobes of the kinase domain. BIBF 1120(Vargatef) inhibit all three VEGFR subtypes with IC50 from 13 to 34 nM. BIBF 1120(Vargatef) can inhibit PDGFRalpha and PDGFRbeta with IC50 of 59 and 65 nM. For FGFRs, BIBF1120(Vargatef) can inhibit FGFR-1, FGFR -2, and FGFR-3 with IC50 69 nM, 37 nM and 108 nM. BIBF 1120 inhibited proliferation of PDGF-BB-stimulated BRPs with an EC50 of 79 nmol/L. And BIBF 1120 can block the activation of MAPK signaling pathway indued by 5% serum plus PDGF-BB at the concentration of 100 nM. BIBF 1120 can also inhibit proliferation of human vascular smooth muscle cells (HUASMC) stimulated by PDGF-BB with an EC50 of 69 nM.
In vivo
BIBF 1120 shows inhibition to ligand-dependent phosphorylation of MAPK and Akt in human endothelial (HUVEC). BIBF 1120 also shows dose-dependent inhibition to ligand-dependent phosphorylation of MAPK and Akt in human bovine retinal pericytes.
