Use | Amuvatinib, also known as MP-470, is an orally bioavailable synthetic carbothioamide with potential antineoplastic activity. Multitargeted receptor tyrosine kinase inhibitor MP470 binds to mutant forms of the stem cell factor receptor (c-Kit; SCFR), inhibiting clinically relevant mutants of this receptor tyrosine kinase that may be associated with resistance to therapy. In addition, MP470 inhibits activities of other receptor tyrosine kinases, such as c-Met, Ret oncoprotein, and mutant forms of Flt3 and PDGFR alpha, which are frequently dysregulated in variety of tumors. |
In vitro study | MP-470 acts on MiaPaCa-2, PANC-1, and GIST882 cells and is toxic with an IC50 of 1.6 μm to 3.0 μm. MP-470 also binds to and inhibits some c-Kit mutants, including the hydrochloride salt of c-Kit MP-470 also inhibits some c-Kit mutants, including c-Kit MP-470 (1 μm) acting on MDA-MB-231 cells, inhibiting tyrosine phosphorylation of AXL. MP-470 acted on LNCaP and PC-3, but not on DU145 cells, was toxic with IC50 of 4 and 8 μm, respectively, and somewhat proliferated at 10 μm. MP-470 (10 μm) acts on LNCaP cells to arrest the cell cycle at G1 phase and reduce Akt and ERK1/2 phosphorylation. MP-470 (10 μm) acts on SF767 cells, inhibits c-Met phosphorylation, and sensitizes cells to radiation. Combined treatment with MP-470 (10 μm) and radiation inhibits GSK-3β activity, induces apoptosis, and may disrupt dsDNA B break repair by inhibiting rad51. [5,6] |
In vivo study | MP-470(10 mg/kg-75 mg/kg by intraperitoneal injection or 50 mg/kg-200 mg/kg by oral treatment) treatment of carrier HT-29, A549, and SB-CL2 cells in a mouse xenograft model to inhibit tumor growth. MP-470(20 mg/kg) combined with Erlotinib significantly inhibited tumor growth in mice bearing LNCaP xenografts. |
