Natural Compounds and Cancer: Current Evidences.

Abstract

Natural compounds are constantly gaining ground in the treatment of various chronic diseases and in cancer research. Recent efforts have been focusing on them due to their special features consisting of low toxicity and high bioavailability. These compounds have already demonstrated important antitumor activity against several cancers in vitro through several mechanisms, including cell viability reduction, suppression of cell proliferation, cell death induction and cell cycle arrest. Herewith, we reviewed natural compounds that can be potentially used for head and neck cancer, glioblastoma and gastrointestinal cancers.
