BackgroundParkinson's disease (PD) is the second most common neurodegenerative disorder after Alzheimer's disease (AD). The exact mechanism behind PD disease is still unknown and PD is marked by symptoms like bradikynesia, tremors, walking or gait difficulties, etc. The current medication used for PD is levodopa, and researchers are trying to develop a promising drug for PD. In our study, we took Ganodema lucidium mushroom, known as “Reishi mushroom,” which has antioxidant, antiinflammatory, antihepatic properties, etc. In our study we took the most five potent Ganodema lucidium extracts, which target Leucine‐rich repeat kinase 2 (LRRK2) that is involved in onset of PD.ObjectiveThis study aims to find the most promising Ganodema lucidium targeting LRRK2 involved in PD.MethodsFirst ADMET analysis was performed for five compounds followed by molecular docking of each compound. Then, we perform molecular dynamics simulation of all five compounds and finally MMGBSA of all five compounds.ResultsBased on molecular dynamics and MMGBSA result we reach the conclusion that Ganoderic Acid A (GAA) is the most promising compound targeting LRRK2. Therefore, GAA needs further validation through in vitro and in vivo studies.
