Design and Semisynthesis of Aminocannabinoids as Neurological Magic Shotguns

“The design of neurological “magic shotguns” represents a modern approach toward the treatment of complex central nervous system disorders, and many natural products like cannabidiol possess distinct potential due to their unique polypharmacological profiles toward central nervous system targets.

Herein, we describe the computational design, semisynthesis, and preliminary biological screening of aminergic cannabidiol derivatives as neurological magic shotguns.

A small library of 22 aminergic cannabidiol derivatives were synthesized and evaluated through radioligand binding assays, revealing that these derivatives generally exhibit higher affinity toward serotonin, dopamine and sigma receptors than the parent compound.

Notably, compounds 8d and 8e displayed significantly improved affinity toward sigma-1 receptors (Ki = 4.8 nM and 8.3 nM, respectively). We then established the functional behavior of compound 8e in mouse primary hippocampal neurons through whole-cell patch clamp assays: exposure to compound 8e potentiates N-methyl-d-aspartate receptors, an effect that may be reversed in the presence of a selective sigma-1 receptor antagonist.

These results suggest that compound 8e behaves as an agonist of sigma-1 receptors, thereby promoting downstream potentiation of N-methyl-d-aspartate receptors.

Altogether, these findings provide preliminary evidence that aminergic cannabinoids, and potentially other derivatives of promiscuous natural products, may hold utility as neurological magic shotguns.”

Lifetime Cannabis Use Is Associated with Brain Volume and Cognitive Function in Middle-Aged and Older Adults

Objective: Cannabis use has increased among older adults, yet the neurocognitive effects in this demographic remain unclear. Prior work has suggested cannabis may increase brain volume in areas rich in cannabinoid (CB1) receptors, though negative effects are often reported in adolescents. This study sought to clarify the relationship between cannabis use and brain health among middle-aged and older adults.

Method: Using data from the UK Biobank, which includes health information from over 500,000 adults, associations between cannabis use, regional brain volume, and cognition in participants aged 40-70 years (mean age = 54.5) were evaluated.

Results: Lifetime cannabis use was positively associated with regional brain volume in CB1-rich regions, including the caudate, putamen, hippocampus, and amygdala. Greater lifetime use was also linked to better performance in learning, processing speed, and short-term memory. Individuals reporting use limited to adolescence also showed larger regional volumes and better cognitive performance than non-users. Sex differences in cannabis effects on brain volume and cognition were also observed.

Conclusions: Results highlight that cannabis may influence brain health differently across the lifespan, potentially offering protective effects in older age while posing risks earlier in development. Protective effects may result from endocannabinoid-mediated modulation of inflammation, immune function, and neurodegeneration. Observed sex differences likely reflect variation in the endocannabinoid system and underscore the importance of considering sex as a biological variable in studies of cannabis and brain health.”

Antioxidant and Antiproliferative Activities of Hemp Seed Proteins (Cannabis sativa L.), Protein Hydrolysate, and Its Fractions in Caco-2 and THP-1 Cells

“This study evaluated the in vitro antioxidant and antiproliferative activity of hemp seed (Cannabis sativa L.) protein isolate, protein hydrolysate, and its fractions. The protein hydrolysate was obtained through sequential enzymatic digestion using pepsin and pancreatin, achieving a degree of hydrolysis of 48.11%. The hydrolysate was then fractionated by ultrafiltration.

Assays conducted on Caco-2 (colorectal cancer) and THP-1 (leukemia) cell lines revealed that the higher-molecular-weight fraction of (>10 kDa) exhibited the strongest, concentration-dependent antiproliferative effect, as determined by the neutral red uptake (NRU) assay for Caco-2 cells and the MTT assay for THP-1 cells. Furthermore, a significant intracellular antioxidant activity was observed, particularly in the whole hydrolysate and its low-molecular-weight fractions, as measured by the DCFH-DA assay in Caco-2 cells.

The results suggest the potential application of hemp seed protein hydrolysate and its fractions as antioxidant and chemoprotective supplements in oncologic therapies.”

https://pubmed.ncbi.nlm.nih.gov/41373886

“This study establishes that hemp seed protein hydrolysate (HSH) and its ultrafiltration fractions possess significant and dual biological activities. The principal finding is the identification of a potent, dose-dependent, and selective antiproliferative effect against colorectal adenocarcinoma (Caco-2) and monocytic leukemia (THP-1) cell lines, with the high-molecular-weight fraction (F1 > 10 kDa) demonstrating the greatest efficacy.

Collectively, these findings underscore the dual potential of hemp seed peptides as a reduction in cell viability agents and potent antioxidants, positioning them as promising candidates for development as functional food ingredients for chemoprevention and as adjuvants in oncological therapies.”

Spectroscopy-Based Evaluation of the Antioxidant Capacity of Hemp (Cannabis sativa)

“In the present study, a comprehensive evaluation of the antioxidant properties of various parts of the hemp plant, specifically its leaves and flowers, in a new feminized variety of Cannabis sativa with an admixture of Cannabis ruderalis was investigated.

Methods such as Electron Paramagnetic Resonance (EPR) and UV-visible (UV-vis) spectroscopy were used to assess trolox equivalent antioxidant capacity (TEAC) and total polyphenol content (TPC). TEAC values of the analyzed samples ranged from 29.5 μmol TE/g DW to 150.2 μmol TE/g DW, while TPC varied between 5.4 mg GAE/g DW and 20.3 mg GAE/g DW.

The findings indicate that hemp exhibits significant antioxidant properties, especially in its leaves. This is attributed to a diverse range of antioxidants, including cannabinoids, flavonoids, and phenolic compounds, which offer notable health benefits.

Furthermore, the method of drying hemp has been shown to influence its antioxidant properties significantly. Research indicates that freeze-dried and air-dried hemp retains higher levels of antioxidant compounds compared to other drying methods. This suggests that selecting an appropriate drying technique is essential for preserving the bioactive compounds responsible for hemp’s antioxidant activity.”

https://pubmed.ncbi.nlm.nih.gov/41373841

“Cannabis plants, in general, owe their antioxidant capabilities to compounds like polyphenols, terpenes, and cannabinoids. Among these, delta-9-tetrahydrocannabinol (THC) and the nonpsychoactive cannabidiol (CBD) are the most recognized. Both THC and CBD exhibit antioxidant activities comparable to vitamins E and C, effectively scavenging free radicals, reducing metal ions, and counteracting oxidative stress.”

“The hemp plant, C. sativa, has emerged as a promising source of natural antioxidants, with various parts of the plant exhibiting diverse levels of antioxidant activity.”

“As global interest in hemp rises, a deeper understanding of its health benefits, particularly its antioxidant properties, will be essential for fully capitalizing on this plant. Research into its bioactive compounds could pave the way for innovative natural remedies and contribute to developing new products that support well-being.”

Unraveling Cannabidiol’s Dual Modulatory Role in Schizophrenia: Network Pharmacology and In Vivo Validation of Neuroinflammatory and Behavioral Modulation

“Schizophrenia (SCZ), a chronic psychiatric disorder, is characterized by cognitive impairment, hallucinations, and delusions, with current antipsychotic treatments offering limited efficacy and considerable side effects.

Cannabidiol (CBD), a non-psychoactive compound from Cannabis sativa, has shown promise in treating neurological and psychiatric conditions, though its precise mechanisms in schizophrenia remain unclear.

Using network pharmacology, this study predicts CBD’s targets and pathways in schizophrenia, highlighting LPS-induced neuroinflammation and implicating 5-HT1AR-MAPK signaling as one potential contributor.

In vitro, CBD (10 mg/kg, i.p.) treatment significantly reduced pro-inflammatory cytokines (e.g., NO, IL-1β, IL-6, TNF-α) and modulated the 5HT1AR-MAPK pathway, including increased 5HT1AR expression and decreased MAPK/ERK1/2 phosphorylation (p < 0.05).

In vivo, CBD alleviated SCZ-like symptoms in a ketamine-induced animal model, reducing anxiety in the open field (p < 0.01) and elevated plus maze tests (p < 0.01), improving spatial memory in the Y-maze (p < 0.01) and social behavior (p < 0.0001) after 5 consecutive days of treatment. Critically, we validated CBD’s central anti-inflammatory effects by demonstrating reduced pro-inflammatory cytokine levels in both plasma and brain tissues (p < 0.05). Further correlation analysis established a direct link between brain cytokine suppression and behavioral improvements, integrating in vitro findings from BV2 microglial cells with in vivo neuroinflammatory and behavioral outcomes.

These findings suggest the potential therapeutic benefits of CBD for SCZ, though further research, particularly clinical trials, is required to validate its efficacy and establish it as a novel therapeutic strategy.”

Development and Characterization of a High-CBD Cannabis Extract Nanoemulsion for Oral Mucosal Delivery

“The cannabidiol (CBD)-rich cannabis extract CAN296 shows anti-inflammatory and anticancer activity relevant to oral lichen planus (OLP), oral graft-versus-host disease (oGVHD), and oral squamous cell carcinoma (OSCC), but its high lipophilicity limits aqueous dispersion.

This study developed a stable Tween-based nanoemulsion optimized for oral mucosal delivery.

Ethanol-dissolved CAN296 was nanoemulsified using a 1% Tween/Span system. Physical stability was visually assessed; droplet size and morphology were examined by dynamic light scattering (DLS) and transmission electron microscopy (TEM); and wettability was measured by static contact angle (SCA). Additional evaluations included temperature stability (25 °C vs. 4 °C), in vitro release using a dialysis membrane, and scanning electron microscopy (SEM) of membrane-associated droplets.

Nanoemulsions with ≥80% Tween 80 incorporated CAN296 up to 800 µg/mL, clear at 400 µg/mL, and uniformly turbid at 800 µg/mL. DLS and TEM confirmed spherical nanoscale droplets, and SCA indicated favorable cohesion and wettability. Stability was maintained for 30 days at 4 °C. Dialysis studies demonstrated strong membrane association with limited diffusion, supported by SEM visualization of membrane-bound droplets.

The Tween-dominant (≥80%) nanoemulsion stably incorporated CAN296 up to 800 µg/mL, demonstrated nanoscale uniformity, improved 4 °C stability, and strong membrane retention under static conditions, suggesting potential for localized oral delivery.”

Molecular Modeling and Analysis of Cannabinoid and Cannabinoid-like Molecules Combining K-Means Clustering with Pearson Correlation and PCA

“More recently, cannabinoid molecules have been widely studied for their potential to treat various diseases.

We used a multidisciplinary approach, combining molecular docking and machine learning tools, to identify cannabinoid-based molecules as potential acetylcholinesterase inhibitors.

We brought together molecules from the classes of cannabinoids, stilbenoids, isoflavones, and other natural products, along with their electronic structure and absorption, distribution, metabolism, excretion and tolerable toxicity (ADMET) data. A novel machine learning framework (MolSimEx, Molecular Similarity Explorer) combining K-means clustering,

Pearson correlation, and principal component analysis was developed to address the similarities of these groups. From the dataset, 30 molecules were selected based on docking scores below -11 kcal/mol. The K-means clustering yielded high classification accuracy on the dataset, correctly grouping the cannabinoid analogues. Additionally, these analogues clustered with classical acetylcholinesterase inhibitors such as huprine-X, huprine-W, and donepezil when considering ADMET and electronic descriptor data.

Radulanin J showed the highest correlation (0.41) with donepezil’s profile, suggesting the potential of cannabinoid-derived compounds as acetylcholinesterase inhibitors.”

Bioreactor-Based Suspension Cultures of Cannabis sativa for Enhanced Production of Anti-Inflammatory Cannabinoid Derivatives

Cannabis sativa synthesizes diverse cannabinoids with significant pharmacological value, but existing suspension cultures show low metabolite yields and limited scalability.

This study establishes bioreactor-based cell suspension system to enhance cannabinoid biosynthesis in C. sativa. Petiole explants cultured on MS medium with 4 mg/L BAP and 0.01 mg/L NAA produced 95.83 ± 0.74% friable callus. Suspension cultures accumulated 352.29 ± 3.90 g/L fresh biomass in 28 days, showing 22.4-fold increase upon scale-up in stirred-tank bioreactor.

Methanolic extracts (60 °C) showed strong anti-inflammatory activity, reducing TNF-α and IL-6 by 88.40 ± 0.87 and 92.03 ± 1.55% at 30 μg mL-1 without cytotoxicity. Metabolomic profiling identified putative cannabinoid derivatives, with THCA-C1 (0.05%) exhibiting highest binding affinity (-8.4 kcal/mol) to inflammatory targets based on docking and dynamics analyses.

Overall, these results provide the first evidence for scalable cannabinoid biosynthesis in bioreactor-grown C. sativa cell suspensions, underscoring their potential for sustainable production of anti-inflammatory therapeutics.”
