SKLB1002 is a potent vascular endothelial growth factor receptor 2 (VEGFR2) inhibitor that inhibits angiogenesis and tumor growth in vivo.
sklb1002 is a potent inhibitor of vegf receptor 2 with ic50 value of 32 nm [1].vegf receptor 2 (vegfr2) is a major receptor for vascular endothelial growth factor (vegf) and plays an important role in angiogenesis and vegf-stimulated proliferation, migration, and sprouting of cultured endothelial cells [1].sklb1002 is a potent vegfr2 inhibitor. in human umbilical vein endothelial cells (huvec), sklb1002 significantly inhibited vegf-induced huvec proliferation with ic50 value of 11.9 μm. also, sklb1002 inhibited huvec migration, invasion and tube formation in a dose-dependent way. sklb1002 (10 μm) significantly inhibited vegf-induced phosphorylation of vegfr2, erk, src and fak [1].in zebrafish embryos, sklb1002 (2.5 μm) significantly inhibited the growth of intersegmental vessels. in mice bearing sw620 or hepg2 xenografts, sklb1002 (100 mg/kg) significantly inhibited tumor volume and inhibited tumor growth by 60%. also, sklb1002 reduced the microvessel density [1]. in mice with 4t1 tumor, sklb1002 significantly reduced the tumor vessel density [2].
