Fisetin is found in various fruits and vegetables. It is reported to have neurotropic, anti-inflammatory, anti-carcinogenic and also other health benefits. Fisetin has been proved to have neuroprotective effect against Parkinson’s disease (PD). Elucidation of the molecular interaction of fisetin with various anti-parkinsonian drug targets leads to better understanding mode of action of the drug. The present study is aimed to study the molecular interaction of fisetin with molecular targets having potential role in PD. The molecular properties and drug likeness model score were first analysed for flavonoid fisetin, which was found to be 0.76. The structures of the molecular drug targets, such as MAO A (2BXR), MAO B (2BYB), COMT (2AVD) and tyrosine hydroxylase (2XSN), was extracted from RCSB-Protein Data Bank. Molecular docking was performed using AUTO DOCK-4.2. The docking scores were evaluated by analyzing the minimum binding energy for the first five runs for all the target proteins. The minimum binding energy for MAO A (2BXR), MAO B (2BYB), COMT (2AVD), tyrosine hydroxylase (2XSN) were -10.22 kcal/mol, -9.68 kcal/mol, -7.45 kcal/mol and -6.67 kcal/mol respectively. Out of the 4 potential PD drug targets, MAO A and MAO, genes responsible for oxidative deamination of dopamine, are predicted to have the least minimum binding energy and best interaction with fisetin.
