Biochem/physiol Actions

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.

The c-Kit receptor can activate distinct signaling pathways including phosphoinositide 3-kinase (PI3K)/Akt and mTOR. Aberrant c-Kit activation protects cells from apoptosis and enhances invasion of colon carcinoma cells. Tandutinib is a novel quinazoline-based inhibitor of the type III receptor tyrosine
