Exploring the Therapeutic Potential of 8-Prenyldaidzein: A Comprehensive Study of its Multi-Target Efficacy in Alzheimer's Disease

Background: Alzheimer's disease (AD) is marked by cognitive decline, amyloid plaques, neurofibrillary tangles, and cholinergic loss. Due to the limited success of amyloid-targeted therapies, attention has shifted to new non-amyloid targets like phosphodiesterases (PDE). This study investigates the potential of Flemingia vestita (FV) phytomolecules and derivatives, particularly 8-Prenyldaidzein, in AD treatment. Materials and Methods: Phytocompounds and derivatives were screened for drug-likeness, toxicity, BBB permeability, and ADME profiles. Molecular docking was conducted with PDE5A, BACE-1, and AChE, followed by molecular dynamics (MD) simulations on the best binding complexes. Results: 8-Prenyldaidzein, a derivative of daidzein, demonstrated favorable drug-likeness and ADME properties. It exhibited strong binding to PDE5A, BACE-1, and AChE, with MD simulations confirming stable protein-ligand interactions. Discussion: The multi-target potential of 8-Prenyldaidzein, particularly through non-amyloid pathways, offers a promising approach to AD therapy. Its inhibition of PDE5A, BACE-1, and AChE could address multiple aspects of AD pathology. Conclusion: 8-Prenyldaidzein shows strong potential as a multi-target inhibitor for AD treatment. While in-silico findings are promising, further experimental validation is needed to confirm its clinical applicability.
