摘要：Abstract Parkinson’s disease (PD) is the second most common neurodegenerative disorder caused due to loss of dopaminergic neurons in substantia nigra pars compacta, which occurs the presence of Lewy bodies made up of Alpha-synuclein (ASN) aggregation resulting in neuronal death. This study aims to identify potent 7,8-Dihydroxyflavone (DHF) derivatives to inhibit the ASN aggregation from in silico analysis. Molecular docking study reveals that carbamic ester derivatives of DHF [DHF-BAHPC ( 8q ), DHF-BAHPEC ( 8s ), DHF-BAHEC ( 8p ), DHF-BDOPC ( 8c ), DHF-BAPEC ( 8n ) and DHF-BAMC ( 8h )] have good binding affinity towards ASN, when compared with DHF and L-DOPA; their docking score values are −16.3120, −16.1875, −15.2223, −14.3118, −14.2893, –14.2810, −14.0383, and −9.1560 kcal/mol respectively. The in silico pharmacological evaluation shows that these molecules exhibit the drug-likeness and ADMET properties. Molecular dynamics simulation confirms the stability of the molecules with ASN. The intermolecular interaction analyzed under the dynamic condition, allows to identify the candidate which potentially inhibits ASN aggregation. Hence, we propose that DHF derivatives are the potential lead drug molecules and preclinical studies are needed to confirm the promising therapeutic ability against PD.
