Description
  • Za použití empirckých i ab initio metod jsme studovali povrchy potenciální energie a dynamickou strukturu nemethylovaných i methylovaných párů bází nukleových kyselin v přítomnosti molekul organických rozpouštědel – methanolu, dimethylsulfoxidu a chloroformu. Podobně jako v roztoku se ukazuje, že v přítomnosti methanolu jsou preferovány patrové interakce mezi bázemi, zatímco v nepolárním chloroformu jsou preferovány planární vodíkově vázané komplexy páru bází.

  • The dynamic structure and potential energy surface of adenine thymine and guanine cytosine base pairs and their methylated analogues interacting with small number of organic solvents (methanol, dimethylsulfoxide and chloroform) were investigated by various theoretical approaches starting from the simple empirical methods to accurate ab initio quantum chemical calculations. All calculations confirmed previous experimental and theoretical results from the bulk solvents showing that whereas in chloroform the base pairs create hydrogen-bonded structures, in methanol, stacked structures are preferred.
