title: 1,4-Naphthoquinone is a potent inhibitor of human cancer cell growth and angiogenesis.
abstract: Angiogenesis inhibitors are beneficial for the prevention and treatment of angiogenesis-dependent diseases including cancer. Vitamin K2 and K3, which are naphthoquinone derivatives, inhibit angiogenesis. We examined the anti-cancer and anti-angiogenic effects of naphthoquinones and its structurally related compounds. Among these 13 compounds, 1,4-naphthoquinone strongly inhibited both human colon cancer cell (HCT116) growth and angiogenesis. To clarify the anti-angiogenic mechanism, the effects of 1,4-naphthoquinone on human umbilical vein endothelial cell (HUVEC) tube formation, proliferation and chemotaxis were examined. Consequently, 1,4-naphthoquinone inhibited HUVEC functions. These results suggest that 1,4-naphthoquinone may be useful to cancer therapy.
