Abstract
Fatty Acid Binding-Protein 5 (FABP5) is a cytoplasmic protein, which binds long-chain fatty acids and other hydrophobic ligands. This protein is implicated in several physiological processes including mitochondrial β-oxidation and transport of fatty acids, membrane phospholipid synthesis, lipid metabolism, inflammation and pain. In the present study, we used molecular docking tools to determine the possible interaction of FABP5 with six selected compounds retrieved form Drugbank. Our results showed that FABP5 binding pocket included 31 polar and non-polar amino acids, and these residues may be related to phosphorylation, acetylation, ubiquitylation, and mono-methylation. Docking results showed that the most energetically favorable compounds are NADH (−9.12 kcal/mol), 5′-O-({[(Phosphonatooxy)phosphinato]oxy}phosphinato)adenosine (−8.62 kcal/mol), lutein (−8.25 kcal/mol), (2S)-2-[(4-{[(2-Amino-4-oxo-1,4,5,6,7,8-hexahydro-6-pteridinyl)methyl]amino}benzoyl)amino]pentanedioate (−7.17 kcal/mol), Pteroyl-L-glutamate (−6.86 kcal/mol) and (1S,3R,5E,7Z)-9,10-Secocholesta-5,7,10-triene-1,3,25-triol (−6.79 kcal/mol). Common interacting residues of FABP5 with nutraceuticals included SER16, LYS24, LYS34, LYS40 and LYS17. Further, we used the SwissADME server to determine the physicochemical and pharmacokinetic characteristics and to predict the ADME parameters of the selected nutraceuticals after molecular analysis by docking with the FABP5 protein. Amongst all compounds, pteroyl-L-glutamate is the only one meeting the Lipinski’s rule of five criteria, demonstrating its potential pharmacological use. Finally, our results also suggest the importance of FABP5 in mediating the anti-inflammatory activity of the nutraceutical compounds.
