General description

An orally bioavailable amino-triazole compound that is shown to bind to the inactive conformations of both PDGFRβ and Raf kinases (allosteric, Type II inh), and acts as a potent inhibitor of Flt3, Kit, PDGFRα and PDGFRβ (Kd = 52, 170, 300 and 520 nM, respectively) with selectivity over B-Raf, p38α, FGFR2 and VEGFR2 (Kd >10 µM) in a multi-kinase panel. Completely blocks the phosphorylations of MEK-1/2 S217/S221, ERK-1/2 T202/Y204 in FGF-stimulated HUVECs, PDGFRβ in PDGF-BB-stimulated VSMCs, ERK-1/2 T202/Y204 in 1205Lu-B Raf V600E cells, and C-Raf S338 at 10 µM. Reduces FGF-induced angiogenesis in mouse Matrigel model (50 mg/kg, i.p., bid) and selectively induces apoptosis in the endothelium; further, suppresses orthotopic renal cell carcinoma growth in mice (100 mg/kg, p.o., qd).
