Özet

Morus alba Linn. is a popular medium-sized tree with a potent neuroprotective activity such as anti-Alzheimer. To date, it is not known which phytocompound of M. alba exerts anti-Alzheimer activity. Therefore, the present study was aimed to identify the phytochemicals of M. alba responsible for the anti-Alzheimer activity by targeting proteins such as acetylcholinesterase (AChE) and glycogen synthase kinase-3 beta (GSK-3β) that are associated in the pathogenesis of Alzheimer disease (AD). Molecular docking, molecular dynamics (MD) simulations and MM-GBSA calculations were performed for the study. Phytocompounds with code 32, 41, 67, and 70 showed the best glide gscore against AchE and GSK-3β. All these phytocompounds interacted with multiple crucial amino acids present at the active binding site of the proteins through conventional hydrogen bonds and hydrophobic interactions. MD simulations of 100 ns revealed stable conformation for all protein-ligand complexes. Based on the computational findings, we conclude that M. alba’s phytoconstituents (32, 41 67, and 70) exerts anti-Alzheimer potential by inhibiting AChE and GSK-3β.
