Abstract:
Parkinsons Disease (PD) is a severe neurodegenerative disorder. It is characterized by the declination of dopaminergic (DA) neurons of substantia nigra pars compacta in the mid brain. Decrease in dopamine level in substantia nigra is a major event in PD. Mutation in Parkin protein is responsible for the onset of Autosomal Recessive Juvenile Parkinsons (ARJP) Disease. Till date, there is no available treatment of PD without any side-effects. Therefore, the focus has been shifted to identifying natural product inhibitors for the treatment of the disorder. Flavonoids, a class of natural products, have proven neuroprotective effects. Some of the flavonoids have their abilities to influence the activities of central nervous system. Therefore, many studies are being conducted to analyze their activities to lower the progression of neurodegenerative diseases. This study was conducted to identify the flavonoids to be used as potential drugs for PD. From the literature, we picked up the flavonoids active on the nervous systems of human beings. We employed a literature mining approach to build a Structure Activity Relationship (SAR) to measure their efficacies. We performed molecular docking simulations using the flavonoids as the ligands and computed their binding free energy values. Our study would therefore point towards future drug- designing endeavours to come up with plausible therapeutics against PD onset.
