Flavonoids from Pancratium aegyptiacum M. Roem.: Exploring the Potential Anti‐Alzheimer's Activity through Network Pharmacology and In Silico Analysis

Le résumé fourni par la source

Abstract The repurposing of therapeutic and preventive strategies against Alzheimer's disease (AD) is progressing rapidly. Pancratium aegyptiacum has been found to possess considerable anticholinesterase potential attributed to its alkaloid contents. In this study, the potential anti‐Alzheimer's activity of isolated flavonoids from P. aegyptiacum was investigated through computational analysis, focusing on the flavonoids rather than their well‐known alkaloids. Molecular docking was performed against three crucial targets involved in the development of AD, and the isolated phytoconstituents were analysed against these targets. Pathway enrichment analyses were also established, additionally, ADMETlab and PASS web servers predicted the pharmacological properties and potential biological functions of the isolated flavonoids. The phytochemical analysis of P. aegyptiacum aerial parts revealed the isolation and identification of eleven flavonoids. They were identified as derivatives of kaempferol (Km), quercetin (Qn) and isorhamnetin (Is). Our investigation revealed that these phytoconstituents potentially act against AD, with several phytochemicals showing superior binding affinity against essential AD targets. The Kyoto Encyclopaedia of Genes and Reactome pathway enrichment database revealed that isolated phytochemicals may have a role in regulating the immune pathway directly correlated to AD. Additionally, these phytochemicals exhibited lower toxicity with pleiotropic biological activities, including dementia treatment and neurotrophic factor enhancement.
