The ONIOM2 (wB97X-D/LANL2DZ:UFF) method was applied to the interaction of transition metal complexes with COX-2 binding site. The Interaction enthalpies and the Gibbs free energies between aspirinate complexes of Cu(II), Zn(II), Fe(III), and In(III) as anti-inflammatory complexes and COX-2  enzyme in the gas phase were calculated. The structure as well as the thermodynamics of optimized metal complexes was debated from the biological point of view. In the gas phase, the interaction was relatively strong and transition metal complexes could be used as potential anti-inflammatory drugs.
