Product Information:

SKLB610 is a VEGFR inhibitor that potently suppresses human tumor angiogenesis. SKLB610 inhibited angiogenesis-related tyrosine kinase VEGFR2, fibroblast growth factor receptor 2 (FGFR2) and platelet-derived growth factor receptor (PDGFR) at rate of 97%, 65% and 55%, respectively, at concentration of 10μM in biochemical kinase assays. SKLB610 exhibited its antitumor activity as a multi-targeted inhibitor with more potent inhibition of VEGFR2 activity. Its potential to be a candidate of anticancer agent is worth being further investigated.

In Vitro:

SKLB610 has a selective inhibition of VEGF-induced proliferation with an IC50 value of 2.2μM. In HUVECs, SKLB610 shows selectivity of 2-fold for inhibition of VEGF-induced proliferation versus bFGF-induced proliferation with an IC50 value of 4.7μM. In HUVECs, SKLB610 blocks VEGF stimulated phosphorylation of VEGFR2 in a dose dependent manner after SKLB610 treatment. SKLB610 significant inhibits HUVECs capillary tube formation in a concentration-dependent manner. SKLB610 inhibits the formation of vessel-like structures at 2.5 μM.

In Vivo:

SKLB-610 inhibits tumor xenograft model growth of human non-smallcell lung cancer model (A549) and human colon cancer model (HCT116) and is well tolerated. After 30 days treatment, SKLB610 exhibited a significantly antitumor activity in inhibiting tumor progress compared with control. The inhibition rate of tumor volume in SKLB610-treated groups is 70.2% (50 mg/kg) for A549 and 77.1% (50 mg/kg) for HCT116 . The retention times of SKLB610 and the internal standard are 5.6 and 8.1 min, respectively. The quantification limit is 67 ng/mL. The calibration curves are linear over a concentration range of 0.1–50 µg/mL.
