PROJECT SUMMARY Synthetic cannabinoids (SC) produce psychological effects resembling those of 9-tetrahydrocannabinol (THC) but are usually more potent and efficacious. Notably, the use of these substance is often associated with greater toxicity. Clusters of severe adverse reactions and death have been reported internationally, including in the U.S. and New Zealand. The global nature of SC abuse argues for an international approach to addressing the problem. To this end, one overall goal of this project is to strengthen a nascent international collaboration initiated among laboratories in the U.S. (RTI International) and New Zealand (University of Otago). Through this collaborative and multi-disciplinary effort, we will determine molecular and pharmacokinetic mechanisms that may underlie differences in the in vivo effects of chemically diverse SC related to their abuse potential and to their toxicological effects in peripheral systems. A foundational hypothesis for this proposed work is that the both the behavioral effects and the toxicological effects associated with SC use are related to their differential interactions with the endogenous cannabinoid system, as compared to THC and other partial CB1 receptor agonists. This hypothesis will be evaluated through systematic study of the SAR of SC and the mechanisms underlying their central and peripheral actions (i.e., their molecular fingerprints). This work will enhance ability to predict which new compounds are likely to have toxicological effects when – or before – they appear and will provide a scientific basis for evaluation of potential health concerns associated with use of these compounds. This research also will increase knowledge of the structure-activity relationships at cannabinoid receptors, resulting in deepened understanding of endocannabinoid system functioning.

项目摘要 合成大麻素（SC）产生类似于9-四氢大麻酚（THC）的心理影响 但通常具有更大的潜力和效率。值得注意的是，这些物质的使用通常与更大 毒性。国际上已经报道了包括在内的严重不良反应和死亡集群 和新西兰。 SC滥用滥用争论的全球性质，以解决国际方法来解决 问题。为此，该项目的总体目标是加强新生的国际合作 在美国的实验室（RTI国际）和新西兰（奥塔哥大学）之间启动。通过这个 协作和多学科的工作，我们将确定分子和药代动力学机制 可能是化学潜水SC与其滥用潜力和与 它们在外围系统中的毒理学作用。这项拟议工作的基本假设是 与SC使用相关的行为效应和毒理作用与其差异有关 与THC和其他部分CB1接收器相比，与内源性大麻素系统的相互作用 激动剂。该假设将通过对SC的SAR和机制进行系统研究来评估 其中心作用（即它们的分子指纹）的基础。这项工作将增强能力 为了预测哪种新化合物可能会产生毒理学影响，而它们出现并将出现并将 为评估与使用这些化合物相关的潜在健康问题提供科学依据。 这项研究还将增加对大麻素受体的结构活性关系的了解， 导致对内源性大麻素系统功能的加深理解。
