Tie2 kinase inhibitor Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden
Tunica interna endothelial cell kinase 2 (Tie2, also known as angiopoietin-1 receptor or tek) is an endothelium-specific receptor tyrosine kinase important for the development of embryonic vasculature and for angiogenesis and vascular maintenance in adult tissues. Tie2 kinase inhibitor reversibly and selectively blocks Tie2 kinase activity with an IC50 value of 250 nM. It is 200-fold more potent for inhibition of Tie2 compared to p38. Tie2 kinase inhibitor has been shown to reduce angiogenesis in a Matrigel neovascularization assay and to delay tumor growth in MOPC-315 plasmacytoma and SVR angiosarcoma xenograft models.[Cayman Chemical]
Verwenden
Tie2 kinase inhibitor.
Definition
ChEBI: 4-[4-(6-methoxy-2-naphthalenyl)-2-(4-methylsulfinylphenyl)-1H-imidazol-5-yl]pyridine is a member of imidazoles.
Biologische Aktivität
genetic studies have identified the crucial roles of tie receptors (tie1 & tie2) in the development and function of endothelial tissues, including promoting the survival, maturation and functional integrity of the vasculature. tie2 kinase inhibitor is suggested to block vascular construction via suppressing tie2, and in this way it is expected to disrupt tumor growth and angiogenesis. [1]
in vitro
tie2 kinase inhibitor exhibited significant inhibitory effect on tie2 auto-phosphorylation and disrupted its downstream signal transduction in a dose dependent manner in human aortic endothelial cells. in addition, tie2 kinase inhibitor exhibits moderately suppressed the activity of tie2 tyrosine kinase in hel cells with ic50 of 232 nm. [2, 3]
in vivo
matrigel mouse model of angiogenesis was adopted for in vivo study. tie2 kinase inhibitor at doses of 25 and 50 mg/kg (i.p., b.i.d) reduced 41% and 70% of angiogenesis, respectively. in a mopc-315 plasmacytoma xenograft model, tie2 kinase inhibitor modestly suppressed tumor growth in nude mice in a dose-dependent manner. [4]
IC 50
a reversible and selective inhibitor of tie2 with ic50 of 0.25 m, whose selectivity is 200-fold higher than that of p38.
