A workflow describing the steps taken in both ligand-based and structure-based approaches to find novel inhibitors for HCV polymerase NS5B. A) the ligand-based search consisted of pharmacophore generation and screening, followed by docking and selection.B) Structure-based NNI work flow consists of identifying the target binding sites and their interaction pharmacophore, a two-stage docking screen, combined with a neural-network ranking model for the hits, and finally, molecular dynamics simulations for the promising hits.
