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.

描述（由申请人提供）：近年来，新的精神活性植物已经在街上出现。一个例子是强烈的致幻薄荷salvia salvia divinorum及其活跃的代谢物萨尔维诺蛋白A。这种致幻剂的使用不受联邦和大多数州法律的监管，正在全国和地球仪上蔓延。自1970年以来，联邦政府将《管制物质法》和大麻（大麻）颁布为法律，并将大麻替代品或替代品开始出现在市场上。 这些植物很容易在众多互联网站点上获得，并且在不久的将来具有成为街头毒品的潜力很高。尽管它们的可用性已经准备就绪，但这些植物及其代谢产物的心理药理学在很大程度上尚不清楚。在大多数情况下，尚未确定这些植物的活性成分或与中枢神经系统相互作用的机制。 该项目的目的是研究用作大麻替代品的精神活性植物的化学和药理学。对于这个项目，我们选择了五种具有互联网销售优惠的大麻补生植物。我们建议在北卡罗来纳大学教堂山分校的NIMH精神活性药物筛查计划下对CNS受体的电池进行生物学评估，并隔离负责其精神作用的活性次级代谢物。从长远来看，该项目发现和开发的中枢神经系统受体的新配体将有助于更好地了解中枢神经系统功能及其疾病。为了实现这些目标，将追求以下具体目标：1。从流行的互联网来源和专业实体中获取所选植物物种。 2。通过汽化/升华过程鉴定活性代谢产物3。选择性提取生物材料。 4。对CNS神经递质受体的亲和力提取物的生物学评估。 5。活性次级代谢产物的生物测定引导分馏和分离。 6。在特定受体系统中阐明分离的代谢产物及其生物重新评估的结构。该项目产生的数据将构成进一步研究的基础，并为寻求更多的资金提供初步结果。
