Abstract

For the first time ever, the quantum-chemical calculation of papaverine molecule was performed within the framework of molecular model by methods RHF/6-311G** and DFT-PBE0/6-311G**. Optimized geometric and electronic structure of this compound was obtained. Its acid strength was also theoretically estimated. It was proved that papaverine molecule belongs to the class of very weak acids (pKa>14). It was shown that 3.4-di(methoxy)benzyl group is the electron-donating substituent. It is revealed, that dimethoxy-group and 3.4-di(methoxy)benzyl group influence on the distribution of electronic density and pKa value.
