Study of Prediction Antiplatelet Potential Targets of TanshinoneⅡ_B by Reverse Molecule Docking

OBJECTIVE To predict the potential targets and the mechanism of tanshinones against platelet activation by reverse docking.METHODS The reverse docking was performed based on Autodock Vina, where tanshinone ⅡB (Tan ⅡB) was screened against several targets that may be activated in platelet aggregation. The interactions between targeted proteins and ligands were analyzed using Discovery Studio Visualizer 4 software.RESULTS Tan Ⅱ B can be well docked into GP Ⅱb/Ⅲ_a with a better predicted affinity than the original ligand RUC-2 (IC₅₀=96 nmol·L^-1).CONCLUSION GP Ⅱb/Ⅲ_a is the most possible target for the Tan Ⅱ B.
