Biochem/physiol Actions

AST487 is an orally available type II tyrosine kinase inhibitor (TKI) that exhibits potent antiproliferation activity against FLT3, RET, PDGFR1, but not BRAF, oncogenic fusions/mutations-driven growth (IC50 = 1.8 nM/FLT3-ITD BaF3, 5.1 nM/FLT3 D835I BaF3, 9-27 nM/TEL-PDGFR1 & PTC3-RET BaF3, <1 nM/FLT3-ITD-expressing MV4-11 &amp; MOLM-13) via binding/stablizing target kinases in the inactive “DFG-out” conformation. AST487 effectively suppresses RET- (NIH3T3-RETC634W & human medullary thyroid cancer (MTC) TT cells) and FLT3-ITD-driven (MV4-11) tumor growth in mice in vivo (20-50 mg/kg/day p.o.).
AST487 is a N,N′-diphenyl urea, which inhibits growth and calcitonin gene expression in medullary thyroid cancer cells.
