Abstract

ABSTRACT:Parkinson's disease (PD) is caused by the alteration of dopamine neurons in the basal ganglia and results in motor symptoms such as tremor and bradykinesia. Activation of metabotropic glutamate receptor 4 (mGluR4) has been shown to modulate neurotransmission in the basal ganglia and results in antiparkinsonian effects in rodent PD models. There are numerous studies indicating that a moderate consumption of red wine provides the protection against neurodegenerative diseases due to the presence of phenolic compounds in wine. Studies have showed that polyphenols found in grape seed extract affects the metabotropic glutamate receptor agonist response in group I mGlu receptors. However, the molecular interaction and conformation between the wine polyphenol and mGluR4 is not available. In our presented study, we designed the 3D model for mGluR4, performed virtual screening and docking studies against wine polyphenols. Further we performed a molecular dynamics simulation to study the conformation. We have proposed Myricitin compound which showed the minimum energy score (−7.3 Kcal/Mol) considered as a potential positive allosteric modulator for mGluR4.
