Bryophyllum pinnatum (L.) Pers. Modulates Multiple Neuroprotective Targets in Alzheimer's Disease: Evidence from Computational and Experimental Validation.
Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, with limited therapeutic options and adverse effects associated with long-term pharmacological treatments. This study investigated the neuroprotective potential of Bryophyllum pinnatum (B. pinnatum) through integrative in silico and in vivo approaches. Network pharmacology and pathway enrichment analyses (KEGG, Cytoscape 3.10.1) were used to identify compound-target network association. Molecular docking using AutoDock Vina and molecular dynamics (MD) simulations for 200 ns using GROMACS were executed to assess the stability of the key ligands and targets. Cognitive impairment was induced in Wistar rats using scopolamine (1 mg/kg, i.p.). Animals were treated with B. pinnatum hydroalcoholic leaf extract (200 and 400 mg/kg, p.o.) and donepezil (3 mg/kg, i.p.) for 30 days. Cognitive and motor functions were evaluated via Morris water maze, elevated plus maze, locomotor activity, and grip strength tests. Biochemical assays measured acetylcholinesterase (ACHE) activity, β-amyloid (Aβ) levels, glutathione, and lipid peroxidation. Histopathological analysis of brain tissue assessed neuronal integrity. In silico analyses identified multiple phytoconstituents involved in AD-relevant pathways, including MAPK, PI3K-Akt, and cholinergic signaling. Diosmin exhibited high binding affinities to ACHE (-10.3 kcal/mol) and MAO-B (-11.2 kcal/mol), with stable binding confirmed via MD simulations. In vivo, B. pinnatum significantly improved cognitive performance, motor coordination, and antioxidant status while reducing Aβ aggregation and ACHE activity (p < 0.05). Histological findings showed reduced neuronal degeneration and neuroinflammation. These results highlight the multitarget neuroprotective potential of B. pinnatum, with diosmin emerging as a promising plant-derived candidate for AD therapeutics.
期刊介绍:
Cell Biochemistry and Biophysics (CBB) aims to publish papers on the nature of the biochemical and biophysical mechanisms underlying the structure, control and function of cellular systems
The reports should be within the framework of modern biochemistry and chemistry, biophysics and cell physiology, physics and engineering, molecular and structural biology. The relationship between molecular structure and function under investigation is emphasized.
Examples of subject areas that CBB publishes are:
· biochemical and biophysical aspects of cell structure and function;
· interactions of cells and their molecular/macromolecular constituents;
· innovative developments in genetic and biomolecular engineering;
· computer-based analysis of tissues, cells, cell networks, organelles, and molecular/macromolecular assemblies;
· photometric, spectroscopic, microscopic, mechanical, and electrical methodologies/techniques in analytical cytology, cytometry and innovative instrument design
For articles that focus on computational aspects, authors should be clear about which docking and molecular dynamics algorithms or software packages are being used as well as details on the system parameterization, simulations conditions etc. In addition, docking calculations (virtual screening, QSAR, etc.) should be validated either by experimental studies or one or more reliable theoretical cross-validation methods.
