Antiangogenic effect of selected phytochemicals.

Abstract

Angiogenesis, the formation of new blood vessels from a preexisting vascular network is considered a key step in tumour growth, invasion, and metastasis. Recent studies show that several natural compounds inhibit angiogenesis and nowadays numerous bioactive plant compounds are tested for their antiangiogenic potential. This review examines current knowledge regarding the antiangiogenic potential of several phytochemicals, including polyphenols resveratrol and curcumin as well as miscellaneous compounds from garlic, Hypericum perforatum, Panax ginseng, Coptis chinensis and Rheum palmatum.
