Isoliquiritin apioside, a component isolated from Glycyrrhizae radix rhizome, significantly decreases PMA-induced increases in MMP9 activities and suppresses PMA-induced activation of MAPK and NF-κB. Isoliquiritin apioside auppresseses invasiveness and angiogenesis of cancer cells and endothelial cells^[1]. In Vitro: Isoliquiritin apioside efficiently suppresses the PMA-induced gelatinolytic MMP-9 activity in HT1080 cells. Isoliquiritin apiosidealso decreases the PMA-induced increase in MMP-9 production in HT1080 cells.Isoliquiritin apioside possesses anti-metastatic and anti-angiogenic abilities in malignant cancer cells and endothelial cells (ECs), with no cytotoxicity^[1].
