Objective: To investigate the antihepatitis activity of Bupleuri Radix and Scutellariae Radix in compatibility by the combination of docking and molecular dynamics simulation. Method: The cycloxygenase-2 (COX-2) plays an important role in alcoholic liver injury. In this study
four active chemical components of Bupleuri Radix and Scutellariae Radix
including baicalin
baicalein
saikosaponin A and saikosaponin D were docked with COX-2
respectively.Then structures of baicalin and baicalein complexed with COX-2 were used as the initial structure of molecular dynamics simulation and molecular mechanics-paison boltzmann surface area(MM-PBSA) calculation research. Result: It has been found that saikosaponin A and saikosaponin D in Bupleuri Radix have no binding capability with COX-2 and baicalein in Scutellariae Radix has the strongest binding capacity with COX-2. Conclusion: The results have shown that Scutellariae Radix plays a key role when Bupleuri Radix and Scutellariae Radix interact with COX-2 in compatibility.
