Cannabinoids and Reproduction : A Lasting and Intriguing History Giovanna Cacciola, Rosanna Chianese, Teresa Chioccarelli, Vincenza Ciaramella, Silvia Fasano, Riccardo Pierantoni, RosariaMeccariello and Gilda Cobellis Pharmaceuticals, 2010, 3, 3275-3323. doi : 10.3390/ph3103275 Abstract : Starting from an historical overview of lasting Cannabis use over the centuries, we will focus on a description of the cannabinergic system, with a comprehensive analysis of chemical and pharmacological properties of endogenous and synthetic cannabimimetic analogues. The metabolic pathways and the signal transduction mechanisms, activated by cannabinoid receptors stimulation, will also be discussed. In particular, we will point out the action of cannabinoids and endocannabinoids on the different neuronal networks [...]

Depuis l’été 2019, plusieurs pays européens ont observé la circulation de résine et d’herbe de cannabis très faiblement dosées en Δ-9-tetrahydrocannabinol (THC), avec ou non du cannabidiol (CBD), adultérées avec des cannabinoïdes de synthèse (Autriche, Suisse)1. Ces produits sont vendus de façon trompeuse comme du simple cannabis. En France, ce phénomène a été rapporte par plusieurs associations (en Provence-Alpes-Côte d’Azur et Bourgogne-Franche-Comte), sans qu’il y ait eu des analyses sur le territoire français jusqu’à maintenant. Ces herbes ou résines ont un [...]

Schoeder, Cornelius Hess, Burkhard Madea, Jens Meiler, Christa E. Müller Forensic Toxicology, 2018, 36, 385-403. Doi : 10.1007/s11419-018-0415-z Abstract Purpose : In the present study we characterized a series of synthetic cannabinoids containing various heterocyclic scaffolds that had been identified as constituents of “Spice”, a preparation sold on the illicit drug market. All compounds were further investigated as potential ligands of the orphan receptors GPR18 and GPR55 that interact with some cannabinoids. Methods : The compounds were studied in radioligand binding assays to determine their affinity for [...]

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 [...]
