Meanwhile, during molecular docking simulations, the affinity energies of Daidzein, Matrine, and Sophoridine binding to these apoptotic proteins were found to be lower than −5.0 kcal/mol, which suggests, to some extent, that JUN, BCL2, CASPASE3, and FOS are the key targets of QJSB to ameliorate leukopenia. Here, FOS is linked to Decreased total leukocyte count.
