Anti-Angiogenetic Agents from the Sea: A New Potential Preventive and Therapeutic Wave?

Angiogenesis, generation of novel blood vessels from pre-existing ones, is a prerequisite for the physiological expansion, reparation, and functioning of body tissues and systems. However, it is also involved in some pathological inflammatory situations, such as oncologic and chronic degenerative disorders. The correct angiogenesis and neo-vascular response also accompanies wound healing, interaction with biocompatible materials, and tissue regeneration. In this respect, natural products deriving from terrestrial and marine plants/organisms may prevent and even cure various angiogenesis-dependent disorders. Bioactive natural compounds with antioxidant and anti-inflammatory activities could concur to maintain adequate vascularization and endothelial functions and inhibit angiogenesis, thus controlling tumor development. This review aims to illustrate the role of some marine-derived compounds as anti-angiogenetic agents.
