In-vitro and in-silico correlation studies of natural ache inhibitors: An approach towards Alzheimer’s disease

Alzheimer’s disease(AD) is one of the damaging neurodegenerative disorders portrayed by the deterioration of cognizance. AChE is involved in the termination of impulse transmission by hydrolysis of acetylcholine. The inactivation of AChE by various inhibitory drugs increases the accumulation of neurotransmitters in the cortex of the brain and normalizes the disrupted neurotransmission. Ayurveda is one of the oldest systems of medicine that uses a variety of crude drugs for memory-related disorders. Ashwagandha and Brahmi are widely used in Ayurveda for various ailments and also as a memory enhancer. The aim of the present study is to understand the effect of hydroalcoholic extracts of Withania somnifera and Centella asiatica, and their markers like Withanolide-A and Asiaticoside on AChE inhibition by in-vitro and in-silico screening model. Both the enriched extracts and marker compounds have favorable inhibitory activity and proved the potential candidates in the management of memory-related disorders.
