Conformation of the tridimensional structure of 1,2,3,4,6-pentagalloyl- β-D-glucopyranose (PGG) by ~1H NMR, NOESY and theoretical study and membrane interaction in a simulated phospholipid bilayer: A first insight

摘要

1,2,3,4,6-Penta-O-galloyl-β-D-glucopyranose (PGG) is a polyphenolic compound found in substantial amounts in a number of medicinal herbs. We report (i) its conformational analysis by solution NMR and molecular dynamics calculation and (ii) theoretical study of its interaction with a model membrane bilayer. The galloyl groups B and E appear to play important roles in the interaction with the phospholipid bilayer.
