DESCRIPTION (provided by applicant): The drug abuse problem in general and the widespread use of marijuana, in particular, have focused attention on the chemistry and pharmacology of the plant Cannabis Sativa. In the decade since the discovery of the cannabinoid receptors, much progress has been made in the cannabinoid field. It has been established that there are at least two types of cannabinoid receptors; CB1 receptors which are present both inside and outside the central nervous system (CNS) and CB2 receptors which are found mainly in the periphery. Two main endogenous ligands have been discovered, anandamide (AEA) and 2-arachidonylglycerol (2-Ara-G1). Also known as endocannabinoids, they are both present in central as well as peripheral tissues. The long term goal of this program is to develop Structure Activity Relationships (SAR) of AEA which are eicosanoids, and bear no chemical/structural relationship to other cannabinoids. We feel that SAR of AEA will be critical for understanding how AEA and other cannabinoids interact with the same receptor. Our specific aims are (i) to continue to examine the SAR of arachidonic acid portion of AEA (ii) to develop AEA/THC (tetrahydrocannabinol) hybrids (iii) to develop novel anandamide membrane transporter (AMT) probes and (iv) to synthesize hydroxylated AEA analogs as potential metabolites of AEA. The synthesis of these analogs and their subsequent biological evaluation will provide us with more potent agonists, partial agonists and antagonists in the AEA series. This may result in the discovery of a silent antagonist with an AEA template and could lead to the discovery of other cannabinoid subtype receptors, reveal mechanisms involved in brain function, and lead to the development of therapeutic drugs in the areas of inflammation, pain, vasodilation, antitumor therapy and other CNS related diseases. The proposed study will increase our understanding of the pharmacological action of this important class of compounds, leading to the discovery of new drugs for the health care field.

描述（由申请人提供）：一般的药物滥用问题，特别是大麻的广泛使用，引起了人们对大麻植物化学和药理学的关注。自发现大麻素受体以来的十年间，大麻素领域取得了很大进展。已经确定至少有两种类型的大麻素受体： CB1 受体存在于中枢神经系统 (CNS) 内部和外部，CB2 受体主要存在于外周。已发现两种主要的内源配体：花生四烯酸乙醇胺 (AEA) 和 2-花生四烯酸甘油 (2-Ara-G1)。也称为内源性大麻素，它们都存在于中枢和外周组织中。该计划的长期目标是开发 AEA 的结构活性关系（SAR），AEA 是类二十烷酸，与其他大麻素没有化学/结构关系。我们认为 AEA 的 SAR 对于理解 AEA 和其他大麻素如何与同一受体相互作用至关重要。我们的具体目标是 (i) 继续研究 AEA 花生四烯酸部分的 SAR (ii) 开发 AEA/THC（四氢大麻酚）杂合体 (iii) 开发新型大麻素膜转运蛋白 (AMT) 探针以及 (iv) 合成羟基化 AEA 类似物作为 AEA 的潜在代谢物。这些类似物的合成及其随后的生物学评价将为我们提供AEA系列中更有效的激动剂、部分激动剂和拮抗剂。这可能导致以 AEA 模板发现沉默拮抗剂，并可能导致其他大麻素亚型受体的发现，揭示涉及大脑功能的机制，并导致炎症、疼痛、血管舒张、抗肿瘤治疗和其他中枢神经系统相关疾病领域治疗药物的开发。拟议的研究将增加我们对这一类重要化合物的药理作用的理解，从而促进医疗保健领域新药的发现。
