- Abstract: [Display omitted] • Scopolamine interacts with ct-DNA at its grooves. • Electrostatic interaction and van der Waals forces are the stabilizing forces. • Scopolamine-ct-DNA complex was found to be stable during the simulation process. • Scopolamine was found to be genotoxic. Scopolamine is used to treat various CNS disorder like urinary incontinence, motion sickness, spasmic movements. Despite its pharmaceutical properties, its interaction with DNA is not yet reported. In this article, the interaction between scopolamine and ct-DNA is reported using a combination of biophysical techniques. UV–visible and steady-state fluorescence spectroscopy were used to study interaction and complex formation. Competitive displacement assays and potassium iodide quenching confirmed the mode of binding between scopolamine and DNA. Structural changes induced in the ct-DNA in the presence of scopolamine were evaluated by CD spectroscopy. The plasmid nicking and NBT assay confirmed the genotoxic effect of scopolamine. In-silico study by molecular docking and molecular dynamics simulation revealed the mode of interaction, major stabilizing forces as well as the nucleotide sequences to which the scopolamine binds.
