Investigations into cholinesterase inhibition have received attention from researchers in recent years for the treatment of Alzheimer’s disease. Cholinesterase enzymes, namely, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), hold pivotal significance disease (AD) treatment. In this study, we utilized ethanolic extract Astragalus crenatus followed by liquid chromatography–electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) to separate identify at least 21 compounds extract. Rosmarinic acid exhibited highest concentration (96.675 ± 1.3 mg/g extract), succeeded hesperidin (79.613 1.2 hesperetin (75.102 1.4 rutin (68.156 1.6 chlorogenic (67.645 1.5 fisetin (66.647 2.3 hyperoside (63.173 extract). A. efficiently inhibited both AChE BChE activities a dosage-dependent manner. Molecular docking was employed scrutinize anticholinesterase mechanisms identified phytocompounds. Notably, network pharmacology analysis executed most efficacious compound. Based on binding energies, emerged as potent inhibitor against BChE, exhibiting scores −10.5 Kcal/mol −9.8 Kcal/mol, respectively. Due its dual activities, holds promise development novel therapeutics aimed neurological disorders, particularly AD.

Abstract In females, Alzheimer's disease (AD) incidences increases as compared to males due estrogen deficiency after menopause. Estrogen therapy is the mainstay for menopause and associated complications. Estrogen, a hormone with multifaceted physiological functions, has been implicated in AD pathophysiology. plays crucial role amyloid precursor protein (APP) processing overall neuronal health by regulating various factors such brain‐derived neurotrophic factor (BDNF), intracellular calcium signalling, death domain‐associated (Daxx) translocation, glutamatergic excitotoxicity, Voltage‐Dependent Anion Channel, Insulin‐Like Growth Factor 1 Receptor, estrogen‐metabolising enzymes apolipoprotein E (ApoE) polymorphisms. All these impact physiology of postmenopausal women. replacement therapies play an important treatment strategy prevent However, use may lead increased risks breast cancer, venous thromboembolism cardiovascular disease. Various therapeutic approaches have used mitigate effects on AD. These include therapy, Selective Receptor Modulators (SERMs), Beta (ERβ)‐Selective Agonists, Transdermal Delivery, Localised Combination Therapies, Metabolism Modulation Alternative Estrogenic Compounds like genistein from soy, notable phytoestrogen plant sources. mechanism via which modulate women not explained earlier thoroughly.
