Ovalitenone is a flavonoid compound that can be isolated from the plant Millettia peguensis. It shows no cytotoxic effects on lung cancer H460 and A549 cells, but it significantly inhibits anchorage-independent growth, CSC-like phenotypes, colony formation, and the migration and invasion capabilities of cancer cells. Ovalitenone can significantly reduce the levels of N-cadherin, snail, and slug, while increasing E-cadherin, thus inhibiting the EMT pathway. Additionally, Ovalitenone suppresses the signaling pathways regulated by focal adhesion kinase (FAK), ATP-dependent tyrosine kinase (AKT), mammalian target of rapamycin (mTOR), and cell division cycle 42 (Cdc42)[1][2].
