Abstract
Suppression of leukemia, colon cancer, myeloma, and fibrosarcoma to some extent by omega 3 fatty acid bound phospholipids has been reported in the last two decade. However, the anti-angiogenic activity of those phospholipids is still not known. Four kinds of marine phospholipid molecular species i.e. starfish EPA bound diacyl phospholipid (EPA-PC), EPA bound monoacyl phospholipid (EPA-LPC) which was prepare via Lipozyme RMIM mediated partial hydrolysis of EPA-PC, squid DHA bound diacyl phospholipid (DHA-PC), and DHA bound monoacyl phospholipid (DHA-LPC) which was also prepare via Lipozyme RMIM mediated partial hydrolysis of DHA-PC, were subjected to antiangiogenic activity assay by using a piece of rat main artery and a human umbilical cord vein endothelial cell. The lengths of micro vein generated from those tissues after incubation with the above four kinds of phospholipid molecular species were measured and compared. EPA-LPC and DHA-LPC showed strong antiangiogenic activity on the rat main artery tissue, while on the human umbilical cord vein endothelial cells, 100 µM of EPA-LPC in the culture medium, exhibited the most effective suppression on angiogenesis, followed by 100 µM of DHA-LPC. It was concluded that EPA-LPC obtained via Lipozyme RMIM mediated partial hydrolysis of EPA-PC is the most effective omega 3 phospholipid on anti-angiogenesis.
