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.
Method: 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.
