Protein kinase CK2 is involved in a broad range of physiological events. 3,8-dibromo-7-hydroxy-4-methylchromen-2-one (DBC) analogues show favorable inhibitory activity targeting CK2α. Two methods were used to build 3D-QSAR models for DBC derivatives. The ligand-based (LB) studies were performed based on the lower energy conformations employing atom fit alignment rule. The receptor-based (RB) models were also derived using bioactive conformations. Contour maps of RB CoMSIA model (q2 = 0.694, r2 = 0.916, N (no. of components) = 7, r2pred = 0.87) including the steric, electronic, hydrophobic and hydrogen bond acceptor fields were employed to explain factors affecting activities of inhibitors. The good consistency between the contour maps and the properties of CK2α amino acids provide useful hints for new inhibitors design.
The 3D QSAR study of CK2 inhibition by 7-hydroxycoumarin derivatives based on two methods (ligand-based and receptor-based) is reported.Figure optionsDownload as PowerPoint slide
