“Cannabidiol (CBD), a major non-psychoactive component of the cannabis plant, has shown therapeutic potential in Alzheimer’s disease (AD). In this study, we identified potential CBD targets associated with AD using a drug-target binding affinity prediction model and generated CBD analogs using a genetic algorithm combined with a molecular docking system. As a result, we identified six targets associated with AD: Endothelial NOS (ENOS), Myeloperoxidase (MPO), Apolipoprotein E (APOE), Amyloid-beta precursor protein (APP), Disintegrin and metalloproteinase domain-containing protein 10 (ADAM10), and Presenilin-1 (PSEN1). Furthermore, we generated CBD analogs for each target that optimize for all desired drug-likeness properties and physicochemical property filters, resulting in improved pIC50 values and docking scores compared to CBD. Molecular dynamics (MD) simulations were applied to analyze each target’s CBD and highest-scoring CBD analogs. The MD simulations revealed that the complexes of ENOS, MPO, and ADAM10 with CBD exhibited high conformational stability, and the APP and PSEN1 complexes with CBD analogs demonstrated even higher conformational stability and lower interaction energy compared to APP and PSEN1 complexes with CBD. These findings demonstrated the capable binding of the six identified targets with CBD and the enhanced binding stability achieved with the developed CBD analogs for each target.”

“The use of cannabinoids (substances contained specifically in hemp plants) for therapeutic purposes has received increased attention in recent years. Presently, attention is paid to two main cannabinoids: delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). With respect to the psychotropic effects and dependence potential of THC (though it is very mild), its use is associated with certain restrictions, and thus the therapeutic properties of CBD are frequently emphasized because there are no limitations associated with the risk of dependence. Therefore, this review covers the main pharmacodynamic and pharmacokinetic features of CBD (including characteristics of endocannabinoidome) with respect to its possible beneficial effects on selected diseases in clinical practice. A substantial part of the text deals with the main effects of CBD on aging, including Alzheimer’s disease and related underlying mechanisms.”

“According to all the results of the available clinical studies, CBD has shown clear therapeutic efficacy in the elderly human population. The frequency of side effects is comparable to other classes of drugs, and the risks of using CBD in elderly patients are rated as moderate.”

“Cannabis has shown promise in treating various neurological disorders, including Alzheimer’s disease (AD). AD is a devastating neurodegenerative disorder that affects millions of people worldwide. Current treatments for AD are limited and are not very effective.

This study investigated the enzyme-ligand relationship between nine active components of cannabis and human acetylcholinesterase (HuAChE) enzyme, which is significant in AD. Specifically, computational methods such as quantum mechanics, molecular docking, molecular dynamics, and free energy calculations were used to identify the cannabis phytochemicals with the highest HuAChE affinity and to understand the specific binding mechanisms involved.

Our results showed that cannabichromene and cannabigerol were the cannabis phytochemicals with the highest affinity for HuAChE, with cannabichromene exhibiting the greatest binding energy. However, both substances showed lower affinity than that of the pharmaceutical drug donepezil.

This study suggests that cannabichromene has a specific affinity for the peripheral anionic site (PAS) and acyl-binding pocket (ABP), while cannabigerol predominantly binds to PAS. Also, it was found that cannabichromene has a specific affinity for PAS and ABP, while cannabigerol predominantly binds to PAS.

Our findings suggest that cannabichromene and cannabigerol are potential therapeutic agents, but further research is needed to validate their effectiveness. The specific binding mechanisms identified may also provide helpful information for the design of more effective cannabis-based drugs.

Overall, this study provides valuable insights into the potential of cannabis-based drugs for treating neurological diseases.”

“Alzheimer’s disease (AD) is a complex and multifactorial neurodegenerative disorder, and it is unlikely that any single drug or intervention will be very successful. The pathophysiology of Alzheimer’s disease involves a range of complicated biological processes, including the accumulation of beta-amyloid protein and tau protein. Given the complexity of AD and amyloid accumulation, a combination of interventions remains to be further explored. Here, we investigated the potential of combining β-asarone and cannabidiol (CBD) as a treatment for AD. The study analyzed the combined effects of these two phytochemicals on beta-amyloid (Aβ) protein aggregation and toxicity in bulk solution, in cells as well as in C.elegans. We detailed the morphological and size changes of Aβ₄₀ aggregates in the presence of β-asarone and cannabidiol. More importantly, the presence of both compounds synergistically inhibited apoptosis and downregulated relative gene expression in cells, and that it may also slow aging, decrease the rate of paralysis, enhance learning capacity, and boost autophagy activity in C.elegans. Our studies suggest that multiple drugs, like β-asarone and CBD, may be potentially developed as a medicinal adjunct in the treatment of AD, although further clinical trials are needed to determine the efficacy and safety of this combination treatment in humans.”
