Exploring the neuroprotective effects of chokeberry (×Sorbaronia mitschurinii) extract on Drosophila melanogaster model of Alzheimer’s disease

Aging is accompanied by a widespread deterioration in the state of the body (physiological and psychological) with the concomitant manifestation of neurodegenerative diseases (dementia, Alzheimer’s disease, Parkinson’s disease). Biologically active substances contained in the fruits of chokeberry have previously shown a neuroprotective potential in relation to model organisms in vivo, so we put forward a hypothesis about the possible neurodenegeroprotective potential of the ethanol extract of chokeberry (×Sorbaronia mitschurinii) on Drosophila melanogaster with overexpression of the precursor of human beta-amyloid UAS-Aβ42. Its accumulation in human brain cells triggers the development of Alzheimer’s disease. In this work, we have studied the effect of chokeberry extract at a concentration of 10 mg/ml on the lifespan of Drosophila model of Alzheimer’s disease. The extract increases the median and maximum lifespan of females by 11 %, as well as the median lifespan of males by 2 % but reduces their maximum lifespan by 3 %. These results indicate the neuroprotective effect of chokeberry extract.
