Terpenoids From Cannabis Do Not Mediate an Entourage Effect by Acting at Cannabinoid Receptors David B. Finlay, Kathleen J. Sircombe, Mhairi Nimick, Callum Jones and Michelle Glass Frontiers in Pharmacology, 2020, Volume 11, Article 359, 1-9. doi : 10.3389/fphar.2020.00359 The entourage effect was a proposed explanation for biological observations that endocannabinoid ligand activities can be modified by other lipids released from cells at the same time. An increasing volume of anecdotal reports and interest in the plant have provoked research into the activity of minor chemical constituents of the plant—including volatile terpenoids such as myrcene, a- and b- pinene, b-caryophyllene, and limonene. However, to [...]

Leier, Scotland Farley, and Fikadu G. Tafesse Journal of Natural Products, 2022, 85, 176−184. Doi : 10.1021/acs.jnatprod.1c00946 ABSTRACT : As a complement to vaccines, small-molecule therapeutic agents are needed to treat or prevent infections by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and its variants, which cause COVID-19. Affinity selection−mass spectrometry was used for the discovery of botanical ligands to the SARS-CoV-2 spike protein. Cannabinoid acids from hemp (Cannabis sativa) were found to be allosteric as well as orthosteric ligands [...]

Doi : 10.3390/molecules26092774 Abstract : Cannabis sativa is one of the oldest medicinal plants in the world. It was introduced into western medicine during the early 19th century. It contains a complex mixture of secondary metabolites, including cannabinoids and non-cannabinoid-type constituents. More than 500 compounds have been reported from C. sativa, of which 125 cannabinoids have been isolated and/or identified as cannabinoids. Cannabinoids are C21 terpeno phenolic compounds specific to Cannabis. The non-cannabinoid constituents include: non-cannabinoid phenols, flavonoids, terpenes, alkaloids and others. This review discusses [...]

Doi : 10.3390/ph14020171 Abstract : Current legislation in Italy provides that medical Cannabis may be administered orally or by inhalation. One of the fundamental criteria for the administration of oral formulations is that they deliver a known consistent quantity of the active ingredients to ensure uniform therapies leading to the optimisation of the risks/benefits. In 2018, our group developed an improved Cannabis oil extraction technique. The objective of [...]

Approach to Cannabis Classification Arno Hazekamp, Katerina Tejkalova, and Stelios Papadimitriou Cannabis and Cannabinoid Research, 2016, Volume 1, (1) Doi : 10.1089/can.2016.0017 Abstract Introduction : There is a large disparity between the ‘‘cultural’’ language used by patients using cannabis for selfmedication and the ‘‘chemical’’ language applied by scientists to get a deeper understanding of cannabis effects in laboratory and clinical studies. The distinction between Sativa and Indica types of cannabis, and the different biological effects associated with them, is a major example of this. Despite the widespread use of cannabis by selfmedicating patients, scientific studies are yet [...]

An essay on the history of the term Indica and the taxonomical conflict between the monotypic and polytypic views of Cannabis Jacob L. Erkelens, Arno Hazekamp Bedrocan BV, The Netherlands Cannabinoids, 2014, 9, (1), 9-15. What’s in a name ? An interesting feature of the worldwide subculture devoted to cannabis is the endless number of names given to its preparations (marijuana, pot, weed, kiff, bhang..). On top of that, there is a continuously grow-ing list of names used to describe different varieties and strains of the cannabis plant. As a result of [...]

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 [...]

Quelles conséquences pour le marché italien du chanvre ? Selon Giacomo Bulleri, avocat au conseil d’administration de l’association italienne de chanvre Federcanapa, les conséquences pour le secteur chanvrier italien sont importantes. D’une part, l’inclusion de la fleur de chanvre sur la liste des plantes médicinales suggère que la plante est sur le point d’être reconnue comme un produit agricole. D’autre [...]
