(E/Z)-Locostatin ((E/Z)-UIC-1005) is a racemic of Locostatin. Locostatin (UIC-1005) is a potent RKIP inhibitor. Locostatin binds Raf kinase inhibitor RKIP protein and disrupts the interaction of RKIP with Raf-1 kinase and G protein-coupled receptor kinase 2. Locostatin inhibits cell proliferation and migration. Locostatin aggravates thioacetamide (HY-Y0698)-induced acute liver failure in mice .
