Abstract

Objectives: Alzheimer’s disease is a leading neurodegenerative disorders having serious effect on an individual’s occupational potential and quality of life. The natural and nutritional based remedy is continuing interest for neurological disorders; hence an attempt was made to reveal memory enhancing potential of commonly available fruits, by applying the molecular docking studies. Methods: The study was conducted in aluminium chloride induced Alzheimer’s Wistar albino rats for the period of 28 days. The oral administered animal groups with ethanolic extracts of peels of ripped banana and papaya (200 and 400 mg/ kg, p.o) is comparatively evaluated with positive control rats (donepezil, 1mg/kg. p.o) by behavioural studies like pole climbing test and elevated plus maze test, biochemical and histopathological parameters. Further, interaction of selected leads of banana and papaya peel with selected targets were analysed by Schrodinger Glide software. Results: Memory enhancing effects of peels was supported by shortening of transfer latency (elevated plus maze), increased number of escapes (cooks pole climbing), enhancement of brain tissue antioxidant defensive enzymes such as SOD, Catalase, GSH, reduction of activity of acetylcholine esterase and improvement of histopathological changes. Memory enhancement effect further observed by best docking score and glide energy of selected leads with targets of Alzheimer’s disease such as beta secretase and acetylcholine esterase. Conclusion: On the basis of the present study, the results revealed that peel extracts of papaya and banana and used as adjuvant which shows anti-Alzheimer’s disease.
