Description

Biochem/physiol Actions

Orally active, potent βPDGFR, c-Kit, Flt3 (Flk2, Stk1) receptor tyrosine kinase inhibitor with anti-leukemia efficacy in vitro and in vivo.

Tandutinib (CT53518, MLN518) is a potent receptor tyrosine kinase inhibitor against PDGFRβ, c-Kit, Flt3 (IC50 = 0.20, 0.17, 0.22, 3.43 μM, respectively, against 8 nM PDGF-BB induced autophosphorylation of βPDGFR, βPDGFR/c-Kit, βPDGFR/Flt3, βPDGFR/CSF-1R chimera expressed in CHO cells; IC50 =30 μM against KDR, EFGR, FGFR, InsR, Abl, Src, PKA, PKC, ERK2, MEK1, MKK4/6, p38). Tandutinib prolongs the survival in murine CMML (Baf3 with Tel/βPDGFR chimera) and Flt-3/ITD AML leukemia models (60 mg/kg bid p.o.) with good oral bioavailability.
