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.

1,2,3,4,6-Penta-O-galloyl-β-D-glucopyranose (PGG) is an active ingredient in plants that are commonly used in Chinese medicine to treat inflammation. We demonstrate here that PGG, at 6.25 μM, does not inhibit the growth of Staphylococcus aureus, and yet it prevents biofilm formation

We have shown that 1,2,3,4,6-penta-O-galloyl-α-D-glucopyranose (α-PGG), an orally effective hypoglycemic small molecule, binds to insulin receptors and activates insulin-mediated glucose transport. Insulin has been shown to bind to its receptors on platelets and inhibit platelet activation. In this study we

Adhesion of calcium oxalate (CaOx) crystals to kidney cells may be a key event in the pathogenesis of kidney stones associated with marked hyperoxaluria. Previously, we found that 1,2,3,4,6-penta-O-galloyl-β-D-glucose (PGG), isolated from a traditional medicinal herb, reduced CaOx crystal adhesion

In this study, we analyzed ex vivo the effect of an aqueous extract of Oenothera paradoxa defatted seeds on the formation of neutrophil-derived oxidants. For defining active compounds, we also tested lypophilic extract constituents such as gallic acid, (+)-catechin, ellagic
