Background:

Sunitinib is an oral, multi-targeted and small-molecule inhibitor of receptor tyrosine kinase (RTK) [1].

Sunitinib is a RTK inhibitor against vascular endothelial growth factor receptors (VEGFR1-3), platelet-derived growth factor receptors (PDGFRα and PDGFRβ ), stem cell factor receptor (c-kit), glial cell-line derived neurotrophic factor receptor(RET). Sunitinib has been reported to inhibit the growth in five NPC cell lines (HK1, CNE-2, HON E-1, CNE-1 and C666-1) with the IC50 values of 2.06 ± 0.29μM, 3.45 ± 0.11μM, 4.07 ± 1.07μM, 2.60 ± 0.38 and 7.57 ± 1.74μM, respectively. Apart from these, Sunitinib has been observed to induce apoptosis in NPC cells as well as induce cell cycle arrest at the G0 /G1 phase in HONE-1 and CNE-2 cells. In vivo, Sunitinib treatment could induce a significant reduction in MVD in CNE2 NPC xenograft [1].
