摘要

The selective interactions between 5-fluorouracil prodrug enantiomers [(R)-A/(S)-A] and DNA wereinvestigated through cyclic voltammetry and molecular docking simulation. The investigation indicatesthat interactions between (R)-A/(S)-A and DNA helix can be considered as groove binding. Tocharacterize the binding ability of (R)-A/(S)-A with DNA, binding constants and binding free energieswere obtained via voltammetric data and AMBER software, which illustrate that the DNA moreselectively binds to (R)-A. For the binding strength, the computational results complementexperimental measurements. This study serves as a good reference for the rational design andscreening of enantiomer prodrugs of 5-fluorouracil.
