Psychedelics as a Treatment for Alzheimer’s Disease Dementia, Simon Andrew Vann Jones and Allison O’Kelly, 2020

Psychedelics as a Treatment for Alzheimer’s Disease Dementia Simon Andrew Vann Jones and Allison O’Kelly Cornwall Partnership NHS Foundation Trust, Liskeard, United Kingdom Frontiers in Synaptic Neuroscience, August 2020 | Volume 12 | Article 34 doi : 10.3389/fnsyn.2020.00034   Currently, there are no disease-modifying treatments for Alzheimer’s disease (AD) or any other dementia subtype. The renaissance in psychedelic research in recent years, in particular studies involving psilocybin and lysergic acid diethylamide (LSD), coupled with anecdotal reports of cognitive benefits from micro-dosing, suggests that they may have a therapeutic role in a range of psychiatric and neurological conditions due to their potential to stimulate neurogenesis, provoke neuroplastic [...]

Minor Cannabinoids of Cannabis sativa L., Fabian Thomas & Oliver Kayser, 2019

Minor Cannabinoids of Cannabis sativa L. Fabian Thomas & Oliver Kayser Journal of Medical Science, 2019, 88, (3), 141-149. Doi : 10.20883/jms.367   ABSTRACT Cannabinoids from Cannabis sativa L. play an important role as natural products in clinics. The major cannabinoids compromise tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) and its decarboxylated analogs. In this review, we focus on often neglected minor cannabinoids and discuss biosynthetic and chemical degradation routes to other neglected cannabinoids in Cannabis sativa starting from THCA, CBDA and cannabichromenic acid (CBCA). Based on the literature, patents and scientific reports, essential routes for the chemical modifi cation of cannabinoids are discussed to explain [...]

Ayahuasca : Uses, Phytochemical and Biological Activities, Edgar Antonio Estrella‑Parra et al., 2019

Ayahuasca : Uses, Phytochemical and Biological Activities Edgar Antonio Estrella‑Parra · Julio Cesar Almanza‑Pérez · Francisco Javier Alarcón‑Aguilar Natural Products and Bioprospecting, 2019, 9, 251–265 doi : 10.1007/s13659-019-0210-5   Abstract Ayahuasca (caapi, yajé), is a psychoactive brew from the Amazon Basin region of South America traditionally considered a “master plant.” It is prepared as a decoction from Banisteriopsis caapi and Psychotria viridis, which it is thought that it stimulates creative thinking and visual creativity. Native healers of the Orinoco and Amazon basins have used traditionally ayahuasca as a healing tool for multiple purposes, particularly to treat psychological disorders in the patients, with some beneficial effects experimentally [...]

Role of the endogenous cannabinoid system in nicotine addiction : novel insights, Islam Hany Gamaleddin et al., 2015

Role of the endogenous cannabinoid system in nicotine addiction : novel insights Islam Hany Gamaleddin, Jose M.Trigo, Aliou B. Gueye, Alexander Zvonok, Alexandros Makriyannis, Steven R. Goldberg and Bernard Le Foll Frontiers in Psychiatry, 2015, Vol 6, Article 41, 1-12. doi : 10.3389/fpsyt.2015.00041 Several lines of evidence have shown that the endogenous cannabinoids are implicated in several neuropsychiatric diseases. Notably, preclinical and human clinical studies have shown a pivotal role of the cannabinoid system in nicotine addiction. The CB1 receptor inverse agonist/antagonist rimonabant (also known as SR141716)was effective to decrease nicotine-taking and nicotine-seeking in rodents, as well as the elevation of dopamine induced by [...]

Cannabinomimetric Lipids : From Natural Extract to Artificial Synthesis, Ya-Ru Gao & Yong-Qiang Wang, 2018

Cannabinomimetric Lipids : From Natural Extract to Artificial Synthesis Ya-Ru Gao, Yong-Qiang Wang Natural Products and Bioprospecting, 2018, 8, 1–21 doi : 10.1007/s13659-017-0151-9 Abstract Endocannabinoid system is related with various physiological and cognitive processes including fertility, pregnancy, during pre- and postnatal development, pain-sensation, mood, appetite, and memory. In the latest decades, an important milestone concerning the endocannabinoid system was the discovery of the existence of the cannabinoid receptors CB1 and CB2. Anandamide was the first reported endogenous metabolite, which adjusted the release of some neurotransmitters through binding to the CB1 or CB2 receptors. Then a series of cannabinomimetric lipids were extracted from marine organisms, which [...]

Research Progress of the Antiviral Bioactivities of Natural Flavonoids, Lin Wang et al., 2020

Research Progress of the Antiviral Bioactivities of Natural Flavonoids Lin Wang · Junke Song · Ailin Liu · Bin Xiao · Sha Li · Zhang Wen · Yang Lu · Guanhua Du Natural Products and Bioprospecting, 2020, 10, 271–283 doi : 10.1007/s13659-020-00257-x Abstract Flavonoids are now considered as an indispensable component in a variety of nutraceutical and pharmaceutical applications. Most recent researches have focused on the health aspects of flavonoids for humans. Especially, different flavonoids have been investigated for their potential antiviral activities, and several natural flavonoids exhibited significant antiviral properties both in vitro and in vivo. This review provides a survey of the literature [...]

Determination of cannabinoids in Cannabis sativa L. samples for recreational, medical, and forensic purposes by reversed-phase liquid chromatography-ultraviolet detection, Sanja Zivovinovic, et al., 2018

Determination of cannabinoids in Cannabis sativa L. samples for recreational, medical, and forensic purposes by reversed-phase liquid chromatography-ultraviolet detection Sanja Zivovinovic, Ruth Alder, Martina D. Allenspach and Christian Steuer Journal of Analytical Science and Technology, 2018, 9, 27, 1-10 doi : 10.1186/s40543-018-0159-8   Abstract Background : Currently, an increasing demand of cannabis-derived products for recreational and medical use is observed. Therefore, the reliable and fast quantification of cannabinoids in hemp samples is essential for the control of product from Cannabis sativa, L. strains. In general, gas chromatography (GC) is the method of choice for the quantification of cannabinoids whereas this method is time consuming and the [...]

Δ 9‑Tetrahydrocannabinol Toxicity and Validation of Cannabidiol on Brain Dopamine Levels : An Assessment on Cannabis Duplicity, Swapnali Chetia & Gaurab Borah, 2020

Δ 9‑Tetrahydrocannabinol Toxicity and Validation of Cannabidiol on Brain Dopamine Levels : An Assessment on Cannabis Duplicity Swapnali Chetia · Gaurab Borah Natural Products and Bioprospecting, 2020, 10, 285–296 doi : 10.1007/s13659-020-00263-z   Abstract Δ9-tetrahydrocannabinol (THC) of cannabis is the main psychoactive component which is a global significant concern to human health. Evaluation on THC reported its drastic effect on the brain dopaminergic (DAergic) system stimulating mesolimbic DA containing neurons thereby increasing the level of striatal DA. Cannabidiol (CBD), with its anxiolytic and anti-psychotic property, is potent to ameliorate the THC-induced DAergic variations. Legal authorization of cannabis use and its analogs in most countries led to [...]
