Non-covalent interactions in natural products

Abstract : Natural polyphenols form non-covalent complexes in which π-stacking and H-bonding play a key stabilizing role. The dispersion-corrected DFT calculations have paved the way towards reliable description of aggregation processes of natural products. In this work, these methods are applied at i) understanding of stereo- and regio-selective oligostilbenoids biosynthesis; ii) predicting natural antioxidant aggregation within lipid bilayer membrane, which may allow rationalizing the synergism of vitamin E, vitamin C and polyphenols in their antioxidant action; and iii) modulating optical properties of chalcone derivatives.
