Objective
To perform a secondary screening to identify the using AutoDock Vina.
Drug Discovery Strategy

Part 1: Run the Docking Screening (AutoDock Vina)
Part 2: Obtain the Results/ Ranking of Top Hits
Part 3: Analyze Interactions using Auto Dock tools
Pharmacophore Generation
Part 4: Possible Model Refinement
Conclusion
• Our drug model did not have the same chemical features as the one generated and used in the primary screening.
• The initial model can be refined.
