Abstract:
Introduction: Parkinson’s disease (PD) is a prevalent neurological disease characterized
by the gradual degeneration of dopaminergic neurons leading to a dysfunctional central nervous system.
Recently, major metabolites of Coffea arabica leaves were revealed to exhibit good electronshuttling
potential in Microbial Fuel Cells (MFCs), similar to neurotransmitters dopamine and epinephrine.
Objective: This In silico study aimed to identify the neuroprotective potentials of plant metabolites
from coffee leaves and to determine their physicochemical and pharmacokinetic properties for developing
viable anti-parkinsonian drug design.
Methods: Molecular docking was performed to evaluate the affinity of identified major compounds
in C. arabica against PD-target proteins and compare the results with the binding activity of existing
drugs and natural ligands of the identified protein targets via LibDock scores. The drug-likeness and
ADMET profiles of each ligand were also evaluated using bioinformatics tools.
Results: C. arabica metabolites exhibited various degrees of binding activity against PD targets.
LibDock scores of test compounds showed that catechin, mangiferin, and chlorogenic acid exhibited
higher docking scores than dopamine and levodopa. Physicochemical and pharmacokinetics analysis
of the selected molecules revealed caffeine, catechin, and chlorogenic acid as promising candidates
for drug development with a low risk of drug toxicity.
Conclusion: The present study indicates that Coffea arabica leaves contain promising neuroprotective
active compounds against Parkinson’s disease.
