Health
- TFDG is a scavenger of superoxide in vitro, even more so than EGCG.[1]
- Tea polyphenols including TFDG reduce angiogenesis,[2] which is implicated in non-liquid cancers, an area of intense current research, by decreasing vascular endothelial growth factor production and receptor phosphorylation.[3][4]
- TFDG inhibits activity of the enzyme 3CLpro in vitro.[5]
