The endocannabinoid (eCB) system is implied in various human diseases ranging from central nervous system to autoimmune disorders. Cannabinoid receptor 2 (CB2R) is an integral component of the eCB system. Yet, the downstream effects elicited by this G protein-coupled receptor upon binding of endogenous or synthetic ligands are insufficiently understood-likely due to the limited arsenal of reliable biol. and chem. tools. Herein, we report the design and synthesis of CB2R-selective cannabinoids along with their in vitro pharmacol. characterization (binding and functional studies). They combine structural features of HU-308 and AM841 to give chimeric ligands that emerge as potent CB2R agonists with high selectivity over the closely related cannabinoid receptor 1 (CB1R). The synthesis work includes convenient preparation of substituted resorcinols often found in cannabinoids. The utility of the synthetic cannabinoids in this study is showcased by preparation of the most selective high-affinity fluorescent probe for CB2R to date. The results came from multiple reactions, including the reaction of 4-Bromobutanoic acid(cas: 2623-87-2Safety of 4-Bromobutanoic acid)
4-Bromobutanoic acid(cas: 2623-87-2) belongs to carboxylic acids. The chief chemical characteristic of the carboxylic acids is their acidity. They are generally more acidic than other organic compounds containing hydroxyl groups but are generally weaker than the familiar mineral acids (e.g., hydrochloric acid, HCl, sulfuric acid, H2SO4, etc.).Safety of 4-Bromobutanoic acid
