Network pharmacology and molecular dynamics study of the effect of the Astragalus-Coptis drug pair on diabetic kidney disease

Figure 8 Heatmap of molecular docking binding energies (kcal/mol). The X-axis corresponds to the key target receptor, while the Y-axis represents the core active ingredient. The darker shade of blue in the heatmap indicates a lower binding energy and a stronger binding affinity between the active ingredient and the target.
