Objective: To evaluate the potential biological activities of chalcones by theoretical docking calculation. Methods: Twelve chalcones derivatives were selected as the ligands. Crystal structures of proteins related to common diseases were used as the receptors for calculation. The Schr?dinger software package was employed to dock the molecular into the targets. The grading standard was used to analyze the docking results. Results: Selective targets of chalcones were related to cancer, lipid metabolic disturbance, cardiovascular disease, inflammation, and so on. Conclusion: The biological activities of chalcones founded through virtual evaluation are in accordance with the reports and this technique has great practicality. The study is a meaningful attempt to discover the mechanism of active component in Chinese material medica with a theoretical method.
