Properties of various derivatives of ellipticine and their stacking interactions with adenine-thymine and guanine-cytosine base pairs were investigated with an ab initio corralated method. The dependence of the interaction energy on the distance between an intercalator and a base-pair and on the twist angle between them was investigated. The results were compared with three empirical potentials, two of them were based on the AMBER force field and the other one was based on the Lifson-Hagler empirical potential. The global interaction energy minima geometries of three systems were searched. The performance of the empirical potentials was discussed.

Pomocí ab initio metod byly studovány vlastnosti několika derivátů elipticinu a jejich interakční energie s páry bází DNA. Výsledky byly porovnány s empirickými potenciály.
