“Nabilone (marketed as Cesamet) is a synthetic form of delta-9-tetrahydrocannabinol (Δ⁹-THC), the primary psychoactive component of cannabis (marijuana). Although structurally distinct from THC, nabilone mimics THC’s structure and pharmacological activity through weak partial agonist activity at Cannabinoid-1 (CB1R) and Cannabinoid-2 (CB2R) receptors, however it is considered to be twice as active as Δ⁹-THC. Nabilone is approved by the FDA for the treatment of nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments.” https://www.drugbank.ca/drugs/DB00486
“Age-related cognitive decline has been associated with proinflammatory cytokines, yet the precise relationship between cognitive decline and cytokine load remains to be elucidated. β-caryophyllene (BCP) is a cannabinoid receptor 2 (CB2) agonist with established anti-inflammatory effects that is known to improve memory and increase lifespan. It is of interest to explore the potential of BCP to reduce age-related cognitive decline and proinflammatory cytokine load. In this study, we assessed changes in circulating cytokines across the lifespan, memory performance in young and aged mice, and the effects of BCP on memory function and cytokine load. The plasma levels of 12 cytokines were assessed in male Swiss-Webster mice at 3, 12, and 18 months of age using multiplexed flow cytometry. Working memory was compared in 3 and 12 month-old mice using spontaneous alternations. A dose-response function (100-300 mg/kg, subchronic administration) for BCP-induced memory restoration was determined in 3 and 12 month-old mice. Finally, the effects on cytokine levels of the peak memory enhancing dose of BCP was assessed in 18 month-old mice. Circulating levels of several cytokines significantly increased with age. Multilinear regression analysis showed that IL-23 levels were most strongly associated with age. Aged mice showed deficits in working memory and higher levels of IL-23, both of which were reversed by BCP treatment. BCP appears to reverse age-associated impairments in memory and modulates cytokine production. IL-23 may play a significant role in the aging process, and future research should determine whether it has utility as a biomarker for novel anti-aging therapeutics.”
“Mammalian ω3- and ω6-PUFAs are synthesized from essential fatty acids (EFAs) or supplied by the diet. PUFAs are constitutive elements of membrane-architecture and precursors of lipid signaling molecules. EFAs and long chain PUFAs are precursors in the synthesis of endocannabinoid-ligands of the Gi/o-protein coupled cannabinoid receptors 1 and 2 in the endocannabinoid-system, which critically regulates energy homeostasis, as metabolic signaling system in hypothalamic neuronal circuits, and behavioral parameters. We utilized the auxotrophic fatty acid desaturase 2 deficient (fads2-/-) mouse, deficient in long chain PUFA-synthesis, to follow the age dependent dynamics of the PUFA pattern in the CNS-phospholipidome in unbiased dietary studies of three cohorts on sustained long chain PUFA-free, ω6-arachidonic and ω3-docosahexaenoic acid supplemented diets and their impact on the precursor pool of CB1 ligands. We discovered the transformation of eicosa-all cis-5,11,14-trienoic acid, uncommon in mammalian lipidomes, into two novel endocannabinoids, 20:35,11,14-ethanolamide and 2-20:35,11,14-glycerol, acting as ligands of CB1 in HEK293-cells. Labeling experiments excluded a Δ8-desaturase activity and proved the position-specificity of FADS2. The fads2 -/- mutant might serve as an unbiased model in vivo in the development of novel CB1-agonists and antagonists.”
