Application

Penta-O-galloyl-β-D-glucose hydrate (PCG) has been used as an inhibitor of abdominal aortic aneurysms (AAA) and matrix metalloproteinase (MMP) related metastatic activity.

Biochem/physiol Actions

PGG induces predominantly (caspase dependent) apoptosis in DU145 and LNCaP cells, while inducing autophagy in more resistant PC3 and TRAMP-C2 cells. It appears that PGG targeted signaling downstream of rather than the mTOR itself. Polyphenolic pyranoses were reported (J Biol Chem. 2010, 285 (11), 7892-902) to inhibit the plasminogen activator inhibitor type 1 (PAI-1).
Penta-O-galloyl-β-D-glucose hydrate (PCG) is a polyphenolic gallotannin compound produced by plants. It has an ability to inhibit matrix metalloproteinase (MMP) related metastatic activity. Thus, PCG can be used for treating metastatic activity in squamous cell carcinoma. In addition, it also acts as a potential drug for stabilizing small abdominal aneurysms.
