Protein Tyrosine Kinases

SU-4312, also known as DMBI, is a potent and selective inhibitor of VEGFR and PDGFR tyrosine kinases (IC50 values are 0.8 and 19.4 μM respectively).

5'-Fluoroindirubinoxime (5'-FIO, compound 13), an Indirubin derivative, is a potent FLT3 inhibitor, with an IC50 of 15 nM.

VSPPLTLGQLLS is a small peptide FGFR3 inhibitor, peptide P3, inhibits FGFR3 phosphorylation. VSPPLTLGQLLS inhibits 9-cisRA-induced tracheal lymphangiogenesis and blocks lymphatic endothelial cell (LEC) proliferation, migration, and tubule formation.
