Molecular Docking and Cognitive Impairment Attenuating Effect of Phenolic Compound Rich Fraction of Trianthema portulacastrum in Scopolamine Induced Alzheimer’s Disease Like Condition
Abstract
Dementia is considered as the frequent cause of neurodegenerative mental disorder such as Alzheimer's disease (AD) amongst elderly people. Free radicals as well as cholinergic deficit neurons within nucleus basalis magnocellularis demonstrated to attribute with aggregation of β amyloid which further acts as an essential hallmark in AD. Various phenolic phytoconstituents exists in Trianthema portulastrum (TP) leaves have been reported as active against various neurological disorders. The current investigation was undertaken to evaluate the antiamnesic potential of butanol fraction of TP hydroethanolic extract (BFTP) by utilizing rodent models of elevated plus maze (EPM) and Hebbs William Maze (HWM) along with in vitro and in vivo antioxidant as well as acetylcholinesterase (AChE) inhibition studies. Molecular docking studies were also performed for evaluation of molecular interaction of existed phenolic compounds in BFTP. In vitro antioxidant study revealed concentration dependant strong ability of BFTP to inhibit free radicals. In vitro AChE inhibition study showed competitive type of inhibition kinetics. BFTP significantly reversed (p < 0.005 versus scopolamine) the damaging effect of scopolamine by reducing TL (Transfer Latency) and TRC (Time taken to recognize the reward chamber) in the EPM and HWM, respectively. BFTP also contributed towards increased (p < 0.005 versus scopolamine) enzymatic antioxidant as well as hippocampal acetylcholine (ACh) levels. Histological studies also supported the results as BFTP pretreated mice significantly reversed the scopolamine induced histological changes in hippocampal region. Docking studies confirmed chlorogenic acid has the most significant binding affinity towards AChE. This research finding concludes that BFTP could be a beneficial agent for management of cognition and behavioral disorders associated with AD.

Extracts from Amygdalus spinosissima roots, Peganum harmala, Trianthema portulastrum, Centella asiatica, Citrus reticulata, and Cudrania tricuspidata reduced AChE activity and improved cognitive function in scopolamine-treated mice.
“Extracts from Amygdalus spinosissima roots, Peganum harmala, Trianthema portulastrum, Centella asiatica, and other plants, including Citrus reticulata and Cudrania tricuspidata, have also shown promising results in reducing AChE activity and improving cognitive function in SCO-treated mice [30,31,32,33,34,35].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
