| Bioactivity | DW10075 is a novel, highly selective VEGFR inhibitor that targets the VEGF/VEGF receptor (VEGFR) pathway, which has been shown to be an effective anti-angiogenic approach for cancer therapy. Studies have found that DW10075 selectively inhibits VEGFR-1, VEGFR-2, and VEGFR-3 among 21 kinases, while having no effect on the other 18 kinases, including FGFR and PDGFR. In human umbilical vein endothelial cells (HUVECs), DW10075 significantly prevented VEGF-induced activation of VEGFR and its downstream signaling, thereby inhibiting VEGF-induced HUVEC proliferation. In addition, DW10075 dose-dependently inhibited VEGF-induced HUVEC migration and tube formation, and suppressed angiogenesis in the rat aortic ring model and the chick embryo chorionic membrane model. DW10075 also exhibited antiproliferative activity against 22 different human cancer cell lines, with IC50 values ranging from 2.2 μmol/L (for U87-MG human glioblastoma cells) to 22.2 μmol/L (for A375 melanoma cells). In the nude mouse U87-MG xenograft tumor model, oral administration of DW10075 significantly inhibited tumor growth and reduced the expression of CD31 and Ki67 in tumor tissues. In summary, DW10075 is a potential anti-tumor angiogenesis agent that deserves further development. |
