Understanding binding between donepezil and human ferritin: molecular docking and molecular dynamics simulation approach.

abstract：:Actinomycin D (ActD) is a DNA-binding antitumor antibiotic that appears to act in vivo by inhibiting RNA polymerase. The mechanism of DNA binding of ActD has attracted much attention because of its strong preference for 5'-dGpdC-3' sequences. Binding is thought to involve intercalation of the tricyclic aromatic phenox...
