Abstract:

Tetragalloylglucose (TgG) and digalloylhamamelose (DgH) were found to inhibit adhesion to and invasion through Matrigel of mouse Lewis lung carcinoma LL2-Lu3 cells, which are highly metastatic. TgG inhibited matrix metalloproteinases (MMPs) from the tumor cells like (-)-epigallocatechin gallate, whereas DgH did not. These results suggest that TgG and DgH inhibit tumor cell invasion by inhibiting MMPs and/or cell adhesion of the tumor cells.

Key words:

Tetragalloylglucose - digalloylhamamelose - hamamelitannin - (-)-epigallocatechin gallate - matrix metalloproteinases - cell adhesion - tumor cell invasion
