“…SAF engages in hydrophobic interactions with certain amino acid residues, such as Phe 103, Val 106, Arg 120, Asp 123, Arg 127, Thr 479, and Glu 483. In addition to interacting with intramolecular hydrogen bonds [ 58 ], SAF forms three hydrogen bonds with the Na V -channel residues Pro 104, His 115, and Trp 119, with the bond lengths being 2.81, 3.16, and 2.90 Å, respectively. The binding affinity for the interaction between SAF and MAO-B is –7.8 kcal/mol, and the upper and lower root-mean-square deviations (RMSD) in atomic positions were 49.76 and 60.68, respectively.…”
