Abstract
AbstractHalomonas pacifica CARE‐V15 was isolated from the southeastern coast of India to determine its genome sequence. Secondary metabolite gene clusters were identified using an anti‐SMASH server. The concentrated crude ethyl acetate extract was evaluated by GC–MS. The bioactive compound from the crude ethyl acetate extract was fractionated by gel column chromatography. HPLC was used to purify the 3,6‐diisobutyl‐2,5‐piperazinedione (DIP), and the structure was determined using FTIR and NMR spectroscopy. Purified DIP was used in an in silico molecular docking analysis. Purified DIP exhibits a stronger affinity for antioxidant genes like glutathione peroxidase (GPx), glutathione‐S‐transferase (GST), and glutathione reductase (GSR). Using in silco molecular docking analysis, the protein−ligand binding affinities of GSR (−4.70 kcal/mol), GST (−5.27 kcal/mol), and GPx (−5.37 kcal/mol) were measured. The expression of antioxidant genes were investigated by qRT‐PCR. The in vivo reactive oxygen species production, lipid peroxidation, and cell death levels were significantly (p ≤ 0.05) increased in OA‐induced group, but all these levels were significantly (p ≤ 0.05) decreased in the purified DIP pretreated group. Purified DIP from halophilic bacteria could thus be a useful treatment for neurological disorders associated with oxidative stress.
