Amuvatinib (MP-470)是多靶点抑制剂,对c-Kit(D816H),PDGFRα(V561D)和FLT3(D835Y)的IC50分别为10 nM,40 nM和81 nM。A multi-targeted tyrosine kinase inhibitor of PDGF and c-Kit。
Information
Amuvatinib (MP-470, HPK 56) is a potent and multi-targeted inhibitor ofc-Kit,PDGFRαandFlt3withIC50of 10 nM, 40 nM and 81 nM, respectively. Amuvatinib suppressesc-METandc-RET. Amuvatinib is also active as a DNA repair proteinRad51inhibitor with antineoplas
In vitro
The hydrochloride salt of MP-470 also inhibits several mutants of c-Kit, including c-KitD816V, c-KitD816H, c-KitV560G, and c-KitV654A, as well as a Flt3 mutant (Flt3D835Y) and two PDGFRα mutants (PDGFRαV561D and PDGFRαD842V), with IC50 of 10 nM to 8.4 μM. MP-470 potently inhibits the proliferation of OVCAR-3, A549, NCI-H647, DMS-153, and DMS-114 cells, with IC50 of 0.9 μM–7.86 μM. MP-470 also inhibits c-Kit and PDGFRα, with IC50 values of 31 μM and 27 μM, respectively. MP-470 demonstrates potent cytotoxicity against MiaPaCa-2, PANC-1, and GIST882 cells, with IC50 of 1.6 μM to 3.0 μM. MP-470 also binds to and inhibits several c-Kit mutants, including c-KitK642E, c-KitD816V, and c-KitK642E/D816V. In MDA-MB-231 cells, MP-470 (1 μM) inhibits tyrosine phosphorylation of AXL. In LNCaP and PC-3, but not DU145 cells, MP-470 exhibits cytotoxicity with IC50 of 4 μM and 8 μM, respectively, and induces apoptosis at 10 μM. In LNCaP cells, MP-470 (10 μM) elicits G1 arrest and decreases phosphorylation of Akt and ERK1/2. In SF767 cells, MP-470 (10 μM) inhibits c-Met phosphorylation and sensitizes cells to radiation. In combination with radiation, MP-470 (10 μM) inhibits glycogen synthase kinase (GSK)3β activity, induces apoptosis, and disrupts the repair of dsDNA breaks probably through suppression of Rad51. [6]
In vivo
In mice xenograft models of HT-29, A549, and SB-CL2 cells, MP-470 (10 mg/kg–75 mg/kg via i.p. or 50 mg/kg–200 mg/kg via p.o.) inhibits tumor growth. In mice bearing LNCaP xenograft, MP-470 (20 mg/kg) combined with Erlotinib significantly induces tumor growth inhibition (TGI).
