Newest firstReliable and traceable quantification of cannabinoids is essential for forensic, regulatory, and quality control applications involving cannabis-derived products. However, the limited availability of certified reference materials (CRMs), particularly for minor cannabinoids such as cannabinol (CBN), remains a major analytical challenge. In this work, an integrated analytical and preparative strategy is presented fo…
Open article record in new tab ↗Background: Chemoresistance remains a major obstacle in managing cholangiocarcinoma (CCA). The cannabis plant contains several phytocannabinoids, including cannabidiol (CBD), cannabigerol (CBG), and cannabinol (CBN), which exhibit anticancer properties. However, to the best of our knowledge, their effects on CCA have not been previously investigated. This study aimed to explore the molecular mechanisms underlying…
BACKGROUND: The cannabis plant produces many bioactive compounds, including the major cannabinoids THC and CBD, and many lesser studied “minor” phytocannabinoids including cannabinol (CBN), cannabichromene (CBC), cannabicyclol (CBL), and cannabigerol (CBG). These compounds are touted for various ailments, including pain, inflammation, and anxiety, but experimental data on their effects are lacking, especially that…
Open article record in new tab ↗Δ9-tetrahydrocannabinol (THC), the main psychoactive compound in cannabis, and other drug molecules that have large molar masses, are often described as 'nonvolatile' and are presumed to be carried in exhaled breath aerosols. Large variabilities in THC concentrations in breath have been measured with devices that only collect aerosols; it is possible that neglecting the vapor phase could be responsible. Partitioni…
The prognosis of glioblastoma (GBM) patients remains dismal due to chemoresistance. Repurposing of natural and endogenous compounds, such as the pineal hormone melatonin (MLT) and minor phytocannabinoids like cannabinol (CBN) or cannabigerol (CBG), represents a promising strategy. This study investigates the cytotoxic potential of combining these phytocannabinoids with MLT, evaluating their efficacy both alone and…
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters host cells when the spike receptor-binding domain (RBD) engages angiotensin-converting enzyme 2 (ACE2). Cannabinoid scaffolds have recently been reported to bind S1/RBD, block spike-mediated membrane fusion, and modulate host inflammatory pathways, making them attractive candidates for entry inhibition. Here, we applied an integrated computational…
Interest in nonpsychotropic cannabinoids like cannabinol (CBN) is increasing for pain therapy. This study delivers critical insights into CBN's metabolism and pharmacological effects, uncovering its therapeutic potential for pain reduction. Using metabolomics, we identify CBN-11-OH as the dominant metabolite, with lower levels of CBN-1'-OH and CBN-quinone. Computational simulations reveal CBN's stability at the CY…
Medicinal cannabis is being used worldwide and there is increasing use of novel cannabis products in the community. Cannabis contains the major cannabinoids, Δ9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD), but also an array of minor cannabinoids that have undergone much less pharmacological characterization. Cannabinol (CBN) is a minor cannabinoid used in the community in "isolate' products and is claimed…
Ongoing legalization of cannabis for recreational use contributes to increasing numbers not only of incidents of driving under the influence, but within all forensic fields. In addition, newly emerging cannabinoids such as hexahydrocannabinol (HHC) and the increasing use of cannabidiol (CBD) products have to be addressed. The aims of this study were first to extend laboratory analysis capacity for the "established…
Open article record in new tab ↗Hexahydrocannabinol (HHC), hexahydrocannabiphorol (HHCP) and their acetates, HHC-O and HHCP-O, respectively, are emerging in Europe as alternatives to tetrahydrocannabinol (THC). This study aimed to elucidate the metabolic pathways of the semi-synthetic cannabinoids HHC, HHCP, HHC-O and HHCP-O from incubation with human hepatocytes. The metabolites of HHC were also identified in authentic urine samples. HHC, HHCP,…
Rationale Papillary thyroid carcinoma (PTC) is the most common thyroid cancer that typically affects women ages 20 to 50, presenting as an asymptomatic neck mass. Treatment with total or partial thyroidectomy shows an excellent prognosis. However, investigation of non-invasive therapeutic options with minimal adverse effects is ongoing. This study seeks to investigate the K1 cell line, which consists of PTC cells…
Background Since the passage of the 2018 US Farm Bill there has been a market for cannabinoid products derived from Cannabis sativa L. that contain < 0.3% delta-9 tetrahydrocannabinol (THC). Understanding the characteristics and motivations of cannabinoid product users is crucial for appropriate regulation of these products. Methods We conducted a cross-sectional survey of 1,523 adults 18 years or older using the…
Open article record in new tab ↗Cannabinol (CBN) is a secondary metabolite of cannabis whose beneficial activity on inflammatory diseases of human skin has attracted increasing attention. Here, we sought to investigate the possible modulation by CBN of the major elements of the endocannabinoid system (ECS), in both normal and lipopolysaccharide-inflamed human keratinocytes (HaCaT cells). CBN was found to increase the expression of cannabinoid re…
Semi-synthetic cannabinoids (SSCs) including hexahydrocannabinol (HHC) are emerging on the drug market and sold openly as purportedly legal replacements for cannabis and Δ9-THC. By the beginning of 2024, 24 European countries had identified HHC, often sold openly in edibles (foods/candy), vapes and low-THC cannabis flowers and resins. The SSC market is developing rapidly, with HHC acetate (HHC-O), hexahydrocannabi…
Open article record in new tab ↗This study explores the antioxidant potential and delivery performance of five structurally distinct cannabinoids, with a particular focus on cannabinol (CBN). Comprehensive structural characterization using mass spectrometry (MS) and nuclear magnetic resonance (NMR) revealed key molecular features relevant to antioxidant function. Among the tested compounds, CBN exhibited the most potent and balanced radical scav…
Cannabis sativa is a remarkable source of bioactive compounds, with over 150 distinct phytocannabinoids identified to date. Among these, cannabinoids are gaining attention as potential therapeutic agents for neurodegenerative diseases. Previous research showed that cannabinol (CBN), a minor cannabinoid derived from Δ9-tetrahydrocannabinol, exhibits antioxidant, anti-inflammatory, analgesic, and anti-bacterial effe…
Open article record in new tab ↗Although cannabis is used in a wide range of fields, including medicine and pharmacology, its use is prohibited in Japan because it contains Δ9-tetrahydrocannabinol (Δ9-THC), a compound that exhibits narcotic effects. While cannabis is primarily detected via color-based screening methods at crime scenes, the reaction products and mechanisms associated with these screening methods have not been fully elucidated. To…
Melanogenesis, the key biological process underlying skin hyperpigmentation, is tightly regulated by complex molecular signaling pathways. Consequently, targeting molecular regulators of this pathway is a crucial strategy for developing effective skin-whitening agents. Cannabinol (CBN), a minor cannabinoid, has been largely unexplored owing to its role in modulating skin pigmentation. This study aimed to elucidate…
Background and aims Conduct a pilot randomized double-blind placebo-controlled crossover trial for adults with subthreshold insomnia symptoms to examine the effectiveness of a cannabinoids supplement on sleep quality and health outcomes. Methods Adults with subthreshold insomnia symptoms (N = 20, Mage = 47.40) were randomized to either the Cannabinoids Supplement (CS) or Placebo Condition (PC) for 10 days. The CS…
