Docking simulation between SNAH and COX-2 (6COX). (a) The pink-colored chemical structure represents SNAH, and the COX-2 protein structure complexed with celecoxib is indicated by blue colored. The magnified rectangles indicate the active sites of COX-2 proteins. In the box image, hydrogen bond interactions between COX-2 and SNAH are depicted by green-colored lines. The binding energies of SNAH and celecoxib for COX-2 were −6.4 kcal/mol and −11.1 kcal/mol, respectively. (b) COX-2 enzyme inhibitory activities of SNAH. The commercial standard, celecoxib was used as a positive control at identical concentrations.
