In this paper, molecular docking technique was used to investigate the binding conformation of twelve 2-(oxalylamino) benzoic acid (OBA) inhibitors in the active site of PTP1B. The predicted binding affinities are linearly correlated to the experimental values (r2 = 0.859). Furthermore, comparative molecular field analysis (CoMFA) was conducted based on the binding conformation predicted by molecular docking. The predicted CoMFA model has satisfactory statistical significance and good actual predicted power. The information from molecular docking and CoMFA may give us some valuable hints to the optimization of lead compounds.
The figure showed the inhibitor modification information derived from CoMFA model. Increasing bulk inside green regions and removing bulk from yellow regions favor the inhibitory activity; increasing negative charge in red regions and increasing positive charge in blue regions favor the inhibitory activity.Figure optionsDownload as PowerPoint slide
