Crystal structures of the human cannabinoid receptor 1 (CB1) bound to the agonists AM11542 and AM841 reveal notable structural rearrangements upon receptor activation, and this flexibility may be a common feature among other G-protein-coupled receptors. The human cannabinoid receptor 1 (CB1) is the main target of the plant cannabinoid Î9-tetrahydrocannbinol (Î9-THC), the key psychoactive compound in Cannabis sativa. CB1 is activated by endocannabinoids and is a therapeutic target for pain management, epilepsy and obesity, among others, although an active receptor structure is still lacking. Here, Zhi-Jie Liu and colleagues report the crystal structure of CB1 activated by two potent Î9-THC derivatives, AM11542 and AM841. Both of these agonists have a gem-dimethyl group on their alkyl chain which leads to significant enhancement in their potency and efficacy. Receptor activation involves large-scale structural rearrangements on both extracellular and cytoplasmic sides and a significant reduction in the size of the binding pocket. These conformational changes involve a novel molecular 'twin toggle switch', the synergistic movement of two key residues during activation, which the authors suggest may be common to other G-protein-coupled receptors. The cannabinoid receptor 1 (CB1) is the principal target of the psychoactive constituent of marijuana, the partial agonist Î9-tetrahydrocannabinol (Î9-THC)1. Here we report two agonist-bound crystal structures of human CB1 in complex with a tetrahydrocannabinol (AM11542) and a hexahydrocannabinol (AM841) at 2.80âà and 2.95âà resolution, respectively. The two CB1âagonist complexes reveal important conformational changes in the overall structure, relative to the antagonist-bound state2, including a 53% reduction in the volume of the ligand-binding pocket and an increase in the surface area of the G-protein-binding region. In addition, a âtwin toggle switchâ of Phe2003.36 and Trp3566.48 (superscripts denote BallesterosâWeinstein numbering3) is experimentally observed and appears to be essential for receptor activation. The structures reveal important insights into the activation mechanism of CB1 and provide a molecular basis for predicting the binding modes of Î9-THC, and endogenous and synthetic cannabinoids. The plasticity of the binding pocket of CB1 seems to be a common feature among certain class A G-protein-coupled receptors. These findings should inspire the design of chemically diverse ligands with distinct pharmacological properties.

without intermittent epoxide isolation. When used in conjunction with a classical halide catalyst, the polyoxometalate increased the rate of carbonation in a synergistic double‐activation of both substrates. The cis isomer is shown to be responsible for incomplete conversion and by‐product formation in commercial mixtures of 1,2‐limomene oxide. Carbonation of 8,9‐limonene epoxide furnished the 8,9‐limonene

conformation was coincided with that of the AM11542 CB1 agonist-bound structure, stabilizing the CB1 receptor at the active-state (agonistic functional effect). We have selected oxime trans-8a based on its potency for CB1, and favorable pharmacodynamic profile, such as fast onset and predictable duration of pharmacological action, for evaluation in pre-clinical models of anorexia nervosa.
