VEGFR2/KDR/Flk-1 Ligand

Quercimeritrin (Quercetin-7-O-β-D-glucopyranoside) is an orally active α-glucosidase inhibitor (with an IC₅₀ of 79.88 μM against the Saccharomyces cerevisiae enzyme) and a P-gp substrate, with anti-angiogenic and antioxidant activities. Quercimeritrin does not cross the blood-brain barrier and does not inhibit cytochrome P450 enzymes. Quercimeritrin precisely binds to and inhibits the active sites of c-Kit, MMP-2, Aurora-A kinases and α-glucosidase, thereby disrupting target functions. Quercimeritrin effectively regulates postprandial blood glucose and also exhibits significant anti-angiogenic activity, which inhibits endothelial cell proliferation and microvascular growth. Quercimeritrin can be used in the research of diabetes and breast cancer.

VEGFR-2 ligand-1, Sorafenib (HY-10201) derivative, is a vascular endothelial growth factor receptor 2 (VEGFR2) ligand. VEGFR-2 ligand-1 binds to the ATP-binding pocket of VEGFR2, forms hydrophobic contacts and hydrogen bonds with key binding-site residues. VEGFR-2 ligand-1 can be used for the research angiogenesis-related pathologies.
