Tandutinib is a potent antagonist of platelet-derived growth factor receptor β (PDGFRβ), FLT3, and c-Kit (IC50 = 200, 220, and 170 nM, respectively). It less potently inhibits macrophage colony-stimulating factor 1 receptor (IC50 = 3.4 μM) and does not significantly inhibit other tyrosine or serine/threonine kinases. Tandutinib blocks the growth of cells expressing an internal tandem duplication within the juxtamembrane domain of the FLT3 receptor, found in some acute myelogenous leukemia cells. It also impairs the growth of colon cancer cells through its actions on the c-Kit receptor. Tandutinib reverses multidrug resistance in vitro by impairing the efflux activity of the multidrug resistance protein 7.

ChEBI: An N-arylpiperazine that is piperazine in which the hydrogen attached to the nitrogen at position 1 is replaced by a 6-methoxy-7-[3-(piperidin-1-yl)propoxy]quinazolin-4-yl group, while the hydrogen attached to the nitrogen at position 4
s replaced by a (p-isopropoxyphenyl)aminocarbonyl group. Tandutinib is an inhibitor of tyrosine kinases FLT3, PDGFR and KIT.
