Figure 3: Molecular docking of flavonoids in the active site of GSK3 (PDB: 1Q5K), TACE (PDB: EFV5), ACE (PDB: 3BKL), and BACE1 (PDB: 4DJU). (a) Docking of flavonoids in the active site of GSK3 (green to procyanidin and yellow to epicatechin gallate). (b) Docking of flavonoids in the active site of TACE (green to epicatechin gallate, yellow to procyanidin, and blue to aspalathin). (c) Docking of flavonoids in the active site of ACE (green to aspalathin, yellow to epicatechin gallate, and blue to procyanidin). (d) Docking of flavonoids in the active site of BACE1 (green to sterubin, yellow to aromadendrin, and blue to robinetidinol).
