Interaction of phenylethanoid glycosides and calf thymus DNA / 中国中药杂志

In physiological condition, the interaction of acteoside and forsythoside B with calf thymus DNA using neutral red (NR) as a fluorescence probe were investigated by fluorescence, UV-visible spectrophotometry, viscosity, DNA melting techniques, and molecular docking. It is observed that acteoside and forsythoside B can react with DNA. The major mode of recognition between drug and DNA is groove binding by hydrogen bonds, and the interaction of acteoside with DNA is stronger than that of forsythoside B.
