Today, the diffusion of neoplastic diseases is a widespread phenomenon. Thus, it is always necessary to identify new molecules able to fight them. In this paper, we will deal with the interesting antineoplastic properties of green tea. We will describe the different and plausible anticancer mechanisms of epigallocatechin gallate (EGCG), the major polyphenol found in green tea, and in particular the biochemical and computational discovery of a new target for the treatment of this disease will be discussed. The bio-active substances present in tea are essentially represented by methylxanthines, as well as by the antioxidant phenolic fraction (flavonoids). Among the other active substances contained in lower concentrations there are vitamins (B, C and K), amino acids (L-theanine) and minerals (aluminium and manganese). Tea extracts, particularly EGCG, could represent the starting point for the potential emergence of new drugs for the treatment of neoplastic diseases. Other activities of tea, as the involvement in neurodegenerative diseases prevention, as well as the antioxidant, antibacterial, antifungal and antiviral effects, will be also briefly described.

Abstract
Today, the diffusion of neoplastic diseases is a widespread phenomenon. Thus, it is always necessary to identify new molecules able to fight them. In this paper, we will deal with the interesting antineoplastic properties of green tea. We will describe the different and plausible anticancer mechanisms of epigallocatechin gallate (EGCG), the major polyphenol found in green tea, and in particular the biochemical and computational discovery of a new target for the treatment of this disease will be discussed. The bio-active substances present in tea are essentially represented by methylxanthines, as well as by the antioxidant phenolic fraction (flavonoids). Among the other active substances contained in lower concentrations there are vitamins (B, C and K), amino acids (L-theanine) and minerals (aluminium and manganese). Tea extracts, particularly EGCG, could represent the starting point for the potential emergence of new drugs for the treatment of neoplastic diseases. Other activities of tea, as the involvement in neurodegenerative diseases prevention, as well as the antioxidant, antibacterial, antifungal and antiviral effects, will be also briefly described.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
