Tie2 kinase inhibitor is a reversible and selective inhibitor of Tie2 with an IC50 of 250 nM [1].
Tie2 kinase inhibitor (2 µM) clearly decreased phosphorylation of AKT in TDEC IR- and in TDEC IR+ (TDEC obtained from irradiated GSC). Tie2 kinase inhibitor (2 µM) induced a significant decrease in the number of CD31+ TDEC obtained from non-irradiated SRA5 and SRB1 GSC, but not from non-irradiated SRC3 GSC [2]. Treatment with Tie2 kinase inhibitor (0-3 µg/ml) resulted in significant reduction of both invadopodia and colony formation in fibrin-fibronectin embedded B16F1 cells [3]. SRSF1-WT transfected cells showed more sensitivity to Tie2 kinase inhibition, and SRSF1-Y19F cells showed resistant to the Tie2 kinase inhibitor compared to the empty vector-transfected cells. Tie2 kinase inhibitor showed more intensive effect on the colony-forming properties of SRSF1-WT cells [4]. Tie2 kinase inhibitor(5 µM)treatment decreased P-Akt of primary rat PitNET cells [5].
After subcutaneous implantation of the plugs containing the cells, mice were injected twice daily with the vehicle or the Tie2 kinase inhibitor for 14 days, plugs with TDEC IR+ with Tie2 kinase inhibitor had significantly fewer functional blood vessels than plugs with TDEC IR+ control. The number of hCD31+ vessels was also lower in plugs with TDEC IR+ with Tie2 kinase inhibitor compared to plugs with TDEC IR+ control [2].
