Description
Petunidin is an O-methylated anthocyanidin derived from delphinidin that imparts blue-red pigments to flowers, fruits, and red wine. It has been shown to bind with and suppress the activity of focal adhesion kinase and to inhibit platelet-derived growth factor-induced aortic smooth muscle cell migration, which may confer a protective effect against atherosclerosis. Extracts from
E. jambolana fruit, which is rich in anthocyanins including petunidin, have been used to suppress the proliferation of an HCT116 colon cancer cell line, as well as colon cancer stem cells.
