Abstract:
Background: Parkinson’s Disease is one of the leading neurodegenerative disorders in the
world. Currently, there is still no treatment that could completely cure the disease. Traditional Chinese
Medicine has been a source for drug candidates, and many studies have elucidated its pharmacokinetic
capabilities. Previous studies showed that Magnolia officinalis has anti-inflammatory, antioxidant, and
bioenergy generation activities. Furthermore, the electron-shuttling and bioenergy-stimulating capabilities
of herbal and brain disorder medicines have been linked to their effectiveness as a remedy.
Objective: This preliminary study aims to evaluate the electron-shuttling compounds of Magnolia
officinalis (i.e., acteoside, isoquercitrin, magnatriol B, obovatol, quercitrin, randaiol, and rutin) as
potential drug candidates for Parkinson’s Disease.
Methods: The seven electron-shuttling compounds were individually docked to the five Parkinson’s
Disease-related proteins, namely aromatic L-amino acid decarboxylase, α-synuclein, monoamine
oxidase B, catechol-o-methyltransferase, and A2A adenosine receptor, using LibDock. ADMET predictions
were also made to screen the compounds further.
Results: Molecular docking results showed that all compounds have relatively high LibDock scores
against the proteins, with acteoside, isoquercitrin, and rutin having the highest scores. However,
considering the ADMET results, only magnatriol B, obovatol, and randaiol had optimal properties as
candidates for neurodegenerative drugs.
Conclusion: The electron-shuttling compounds of M. officinalis, magnatriol B, obovatol, and randaiol,
have the potential to be a remedy for Parkinson’s Disease due to their high probability of binding
to the proteins.
