title: [Interaction of DNA nucleotide bases with anticancer drug ThioTEPA: molecular docking and quantum-mechanical analysis].
abstract: Using modern methods of molecular docking, quantum chemistry and quantum theory of atoms in molecules the interaction of anticancer drug ThioTEPA with isolated nucleotide bases and deoxyribonucleosidemonophosphates of DNA has been studied. Physical properties and some trends of binding have been established for the complexes of "nucleotide base + ThioTEPA" and "deoxyribonucleosidemonophosphate + ThioTEPA" types. It has been shown that strong hydrogen bonds of NH...N type are the key factor responsible for high selectivity of binding of ThioTEPA to the guanine-containing units of the DNA.
