DESCRIPTION (provided by applicant): In recent years, new psychoactive plants have been emerging on the streets. An example is the strong hallucinogenic mint Salvia divinorum and its active metabolite salvinorin A. The use of this hallucinogen, unregulated by Federal and most State laws, is spreading across the country and globe. Since 1970 when the Controlled Substances Act was enacted into law by Federal Government and cannabis (marijuana) was placed in the Schedule I, a number of marijuana substitutes or alternatives started to appear on the market. These plants are easily obtained on numerous internet sites and have a high potential of becoming street drugs in the near future. Despite their ready availability, the psychopharmacology of these plants and their metabolites is largely unknown. In most cases, neither the active constituents of these plants nor the mechanisms of their interactions with the central nervous system have been determined. The purpose of this project is the study of the chemistry and pharmacology of psychoactive plants used as marijuana substitutes. For this project, we have selected five marijuana-substitute plant species with prominent internet sales offers. We propose to biologically evaluate these plants against the battery of CNS receptors under the NIMH Psychoactive Drug Screening Program at the University of North Carolina at Chapel Hill, and isolate the active secondary metabolites responsible for their psychotropic effects. In the long-term, new ligands to CNS receptors discovered and developed in this project will contribute to better knowledge of the central nervous system functions and its disorders. To achieve these goals, the following specific aims will be pursued: 1. Acquisition of selected plant species from popular internet sources and professional entities. 2. Identification of active metabolites by vaporization/sublimation process 3. Selective extraction of biological material. 4. Biological evaluation of extracts for affinity to CNS neurotransmitters receptors. 5. Bioassay-guided fractionation and isolation of active secondary metabolites. 6. Structure elucidation of isolated metabolites and their biological re-evaluation in the specific receptor systems. The data generated by this project will form a basis for further research and provide preliminary results for seeking more extensive funding. PUBLIC HEALTH RELEVANCE: With the growing number of psychoactive plants and substances on the streets, concern for people's health, especially that of youth, becomes an increasingly important issue. Many of the emerging hallucinogenic plants advertised via Internet and used as marijuana substitutes are poorly studied. We do not know their mechanism of action in the central nervous system, their potential to become addictive drugs of abuse, their toxicity to vital organs and systems of the human body or other side effects. Our project to study the psychopharmacology of plants used as marijuana substitutes will address these issues and provide information to further research in this area.

描述（由申请人提供）：近年来，街头出现了新的精神活性植物。一个例子是强致幻剂薄荷鼠尾草及其活性代谢物鼠尾草苷a。这种致幻剂的使用，不受联邦和大多数州法律的管制，正在全国和全球蔓延。自1970年联邦政府颁布《受控物质法》并将大麻（大麻）列入附表一以来，市场上开始出现一些大麻替代品或替代品。这些植物很容易在许多网站上获得，在不久的将来很有可能成为街头毒品。尽管它们很容易获得，但这些植物及其代谢物的精神药理学在很大程度上是未知的。在大多数情况下，这些植物的活性成分及其与中枢神经系统相互作用的机制都没有确定。本项目的目的是研究大麻替代品的精神活性植物的化学和药理学。在这个项目中，我们选择了五种大麻替代品，它们在互联网上的销售都很突出。我们建议在北卡罗来纳大学教堂山分校的NIMH精神活性药物筛选项目下，对这些植物进行CNS受体电池的生物学评估，并分离出负责其精神作用的活性次级代谢物。从长远来看，本项目发现和开发的新的中枢神经系统受体配体将有助于更好地了解中枢神经系统功能及其疾病。为实现这些目标，将追求下列具体目标：从流行的互联网资源和专业实体获取选定的植物物种。2. 气化/升华法鉴定活性代谢物生物材料的选择性提取。4. 提取物对中枢神经递质受体亲和力的生物学评价。5. 生物测定引导活性次生代谢物的分离与分离。6. 分离代谢物的结构解析及其在特定受体系统中的生物学再评价。该项目产生的数据将成为进一步研究的基础，并为寻求更广泛的资金提供初步结果。
