Abstract Cannabigerol (CBG) is a minor non-psychoactive cannabinoid present in Cannabis sativa L. (C. sativa) at low levels (<1% per dry weight) that serves as the direct precursor to both cannabidiol (CBD) and tetrahydrocannabinol (THC). Consequently, efforts to extract and purify CBG from C. sativa is both challenging and expensive. However, utilizing a novel yeast fermentation technology platform, minor cannabinoids such as CBG can be produced in a more sustainable, cost-effective, and timely process as compared to plant-based production. While CBD has been studied extensively, demonstrating several beneficial skin properties, there are a paucity of studies characterizing the activity of CBG in human skin. Therefore, our aim was...

In serum-free medium, B lymphoblastoid cells and fibroblasts die after 2 days. We report that submicromolar concentrations of Δ9-tetrahydrocannabinol (THC), Δ8-THC, cannabinol, or cannabidiol, but not WIN 55,212-2, prevented serum-deprived cell death. Δ9-THC also synergized with platelet-derived growth factor in activating resting NIH 3T3 fibroblasts. The cannabinoids' growth supportive effect did not correlate with their ability to bind to known cannabinoid receptors and showed no stereoselectivity, suggesting a nonreceptor-mediated pathway. Direct measurement of oxidative stress revealed that cannabinoids prevented serum-deprived cell death by...

Abstract The present study focuses on assessing the bioactive potential of Cannabis sativa L. seed extracts, specifically the organic and aqueous extracts derived from Ketama hemp seeds harvested in Morocco. We tested the antioxidant capacities of the extracts, specifically their ability to scavenge DPPH free radicals. The ethanolic Cannabis sativa L. seed extract was particularly effective, demonstrating the lowest IC50 value of 0.36mg/mL±0.01, outperforming the reference compound ascorbic acid, which had an IC50 value of 0.68mg/mL±0.02. This suggests a significantly high antioxidant potential of the ethanolic extract against the DPPH radical. The β-carotene bleaching test further supported these findings, with the ethanolic and hexanolic extracts showing substantial antioxidant activity, inhibiting...

Abstract Cannabis sativa products have historically been used for healing purposes; now their biological properties are supported with scientific evidence, but modern research has not yet fully developed its therapeutic potential. This study focuses on the cultivar of C. sativa called strawberry to understand the biological and medical potentials of hydroalcoholic extracts from two different parts of the plant: leaves and inflorescences. Two biological assets were investigated including antioxidant and antimicrobial potential. Additionally, quantitative determination of phenolic and terpenophenol compounds was conducted. The antimicrobial action was highlighted for the hydroalcoholic extract from inflorescences, especially against Escherichia coli and Bacillus subtilis. Among the dermatophytes’ strains, the most sensitive was Arthroderma currey. These effects...

Among other nutrients, they contain a PUFA- and bioactive compounds-rich oil. Accordingly, this work was focused to establish the fatty acids (FA) content, the regiospecificity of triacylglycerols, and to quantify several bioactive compounds of relevant hemp seeds varieties and related taxa. Eight varieties of unhusked hemp seeds and eight samples of commercial husked hemp seeds were studied, and other Cannabaceae seeds: those from hop (Humulus lupulus) and European hackberry (Celtis australis). We found that all hemp seeds varieties constitute a rich source of essential...

Abstract Cannabis leaves contain a diverse range of antioxidants, including cannabinoids, flavonoids, and phenolic compounds, which offer significant health benefits. Utilising cannabis leaves as a source of antioxidants presents a cost-effective approach because they are typically discarded during the cultivation of cannabis plants for their seeds or fibres. Therefore, this presented study aimed to assess the antioxidant activity of the leaves of selected hemp cultivars, such as Białobrzeska, Tygra, and Henola, based on the results obtained with the 2,2′-Azino-bis(3-ethylbenzthiazoline-6-sulfonic acid, ferric reducing antioxidant power, cupric reducing antioxidant capacity, and 2,2-Diphenyl-1-picrylhydrazyl assays. The cannabinoid profile was analysed for the antioxidant activity to the contents of...

Abstract   Cannabidiol (CBD) is one of the main pharmacologically active phytocannabinoids of Cannabis sativa L. CBD is non-psychoactive but exerts a number of beneficial pharmacological effects, including anti-inflammatory and antioxidant properties. The chemistry and pharmacology of CBD, as well as various molecular targets, including cannabinoid receptors and other components of the endocannabinoid system with which it interacts, have been extensively studied. In addition, preclinical and clinical studies have contributed to our understanding of the therapeutic potential of CBD for many diseases, including diseases associated with oxidative stress. Here, we review the main biological effects of CBD, and its synthetic derivatives, focusing on the cellular, antioxidant,...

The neuroprotective effects of Δ 9 -tetrahydrocannabinol (THC) were examined using an in vitro model in which the AF5 CNS cell line was exposed to toxic levels of N-methyl-D-aspartate (NMDA), an agonist of the NMDA glutamate receptor. NMDA toxicity was reduced by THC, but not by the more specific cannabinoid receptor agonist, WIN55,212-2. Addition of dibutyryl cAMP (dbcAMP) to the culture medium did not alter the neuroprotective effect of THC and did not unmask a neuroprotective effect of WIN55,212-2. The cannabinoid antagonist SR141716A did not inhibit the neuroprotection induced by THC or alter the response to WIN55,212-2, even in the presence of dbcAMP, indicating...

Cannabinoids are promising medicines to slow down disease progression in neurodegenerative disorders including Parkinson’s disease (PD) and Huntington’s disease (HD), two of the most important disorders affecting the basal ganglia. Two pharmacological profiles have been proposed for cannabinoids being effective in these disorders. On the one hand, cannabinoids like D9 -tetrahydrocannabinol or cannabidiol protect nigral or striatal neurons in experimental models of both disorders, in which oxidative injury is a prominent cytotoxic mechanism. This effect could be exerted, at least in part, through mechanisms independent of CB1 and CB2 receptors and involving the control of endogenous antioxidant defences. On the other hand, the activation...

Atherosclerosis is responsible for most cardiovascular disease (CVD) and is caused by several factors including hypertension, hypercholesterolemia, and chronic inflammation. Oxidants and electrophiles have roles in the pathophysiology of atherosclerosis and the concentrations of these reactive molecules are an important factor in disease initiation and progression. Overactive NADPH oxidase (Nox) produces excess superoxide resulting in oxidized macromolecules, which is an important factor in atherogenesis. Although superoxide and reactive oxygen species (ROS) have obvious toxic properties, they also have fundamental roles in signaling pathways that enable cells to adapt to stress. In addition to inflammation and ROS, the endocannabinoid system (eCB) is also important in...
