Comparative Approach to Interaction of Zinc Dication with Theobromine and Theophilline-A DFT Treatment
Abstract
Two isomeric methylxanthines, theobromine and theophilline, and their Zn+2 containing composites are considered within the restrictions of density functional theory (B3LYP/ 6-31++G(d,p)). Certain quantum chemical, thermodynamic and spectral data have been harvested, compared and interpreted. The results revealed that theophilline+Zn+2 system is thermodynamically more exothermic, more favorable and electronically stable compared to the analogous system, theobromine+Zn+2.
