    Complexes of CK2 protein kinase with halogenated inhibitors were investigated by means of the advanced semiempirical quantum mechanical PM6-DH2X method. The PM6-DH2X method provides reliable geometries of the CK2 protein kinase-inhibitor complexes that agree well with the X-ray crystal structures. When the Amber empirical potential is applied, this agreement becomes considerably worse. Similarly, the binding free energies determined by the PM6-DH2X SQM method are much closer to the experimental inhibition constants than those based on the Amber empirical potential.
