Sunitinib er identificeret som en hæmmer af receptorerne for trombocytafledte vækstfaktorer (PDGFRα og PDGFβ), vaskulære endotel - vækstfaktorer (VEGFR1, VEGFR2 og VEGF3), stamcellefaktor (KIT), Fms- lignende tyrosinkinase- 3 (FLT3), kolonistimulerende faktor (CSF- 1R) og gliacelleafledt neurotrof faktor (RET).
