Substance that inhibits the growth of new blood vessels
An angiogenesis inhibitor is a substance that inhibits the growth of new blood vessels (angiogenesis). Some angiogenesis inhibitors are endogenous and a normal part of the body's control and others are obtained exogenously through pharmaceutical drugs or diet.
While angiogenesis is a critical part of wound healing and other favorable processes, certain types of angiogenesis are associated with the growth of malignanttumors. Thus angiogenesis inhibitors have been closely studied for possible cancer treatment. Angiogenesis inhibitors were once thought to have potential as a "silver bullet" treatment applicable to many types of cancer, but the limitations of anti-angiogenic therapy have been shown in practice.[1] Currently, angiogenesis inhibitors are recognized for their improvement of cancer immunotherapy[2][3] by overcoming endothelial cell anergy. Angiogenesis inhibitors are also used to effectively treat macular degeneration in the eye, and other diseases that involve a proliferation of blood vessels.[4][5][6]
