  • 3-O-D-galactopyranosylglyceride (GPG; fatty acids R1, R2 = myristic acid 11.62%, palmitic acid 61.90% and oleic acid 26.48%) was isolated from Chrysanthemum coronarium L that has been used for treating renal and cardiovascular diseases as one of vegetables or medicinal drug. However, little was known about the anti-angiogenic activity of GPG. Thus, anti-angiogenic effect of GPG was evaluated in human umbilical vein endothelial cells (HUVECs) in vitro and in vivo. GPG effectively inhibited bFGF-induced migration and invasion of HUVECs in a concentration-dependent manner, whereas it did not inhibit bFGF-induced proliferation and capillary-like tube formation of HUVECs. To examine the mechanism of anti-angiogenic activity of GPG, gelatin zymography was carried out. GPG downregulated the expression of matrix metalloproteinase-2 in a concentration-dependent manner. Furthermore, GPG significantly disrupted bFGF-induced neovascularization on the chick chorioallantoic membrane assay in vivo. These results suggest that 3-O--D-galactopyranosylglyceride may inhibit neovascularization by inhibiting angiogenic activity of endothelial cells via regulation of matrix metalloproteinase-2 (MMP-2).
