应用

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.

生化/生理作用

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

The inhibition of protein tyrosine phosphatase 1B (PTP1B) is of substantial interest for the treatment of type-2 diabetes mellitus. Using an in vitro enzyme assay with human recombinant PTP1B 1,2,3,4,6-penta-O-galloyl-D-glucopyranose was isolated from the roots of Paeonia lactiflora as an

The objective of this study was to quantify pentagalloyl glucose (PGG) mediated biomechanical restoration of degenerated extracellular matrix (ECM). Planar biaxial tensile testing was performed for native (N), enzyme-treated (collagenase and elastase) (E), and PGG (P) treated porcine abdominal aorta

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
