TY - JOUR ID - 490003 AU - Kříž, Zdeněk - Koča, Jaroslav - Imberty, Anne - Charlot, Aurelia - Auzely-Velty, Rachel PY - 2003 TI - Investigation of the complexation of (+)-catechin by b-cyclodextrin by a combination of NMR, microcalorimetry and molecular modeling techniques JF - Organic and Biomolecular Chemistry VL - 1 IS - 14 SP - 2590-2595 EP - 2590-2595 PB - Royal Society of Chemistry SN - 14770520 KW - NMR KW - cyclodextrin KW - catechin KW - molecular modeling N2 - (+)-Catechin is a polyphenolic compound of natural origin that presents anti-oxidant properties of interest for therapeutics or cosmetics uses. Preliminary studies on inclusion into cyclodextrin cavities yielded contradictory results both for the quantitative (a nity constant) and qualitative description of the interaction. By a combination of several experimental and theoretical methods, the present study resolved the previous ambiguities about the interaction between (+)-catechin and b-cyclodextrin. Thermodynamic data measured by isothermal titration calorimetry demonstrate that the binding is enthalpy driven. Excellent agreement has been obtained for the measurement of the association constant by NMR and microcalorimetry. The several docking modes obtained by systematic docking studies have been compared to intermolecular contacts measured by NMR and the overall geometry of the complex can be proposed. ER -
