项目摘要

PROJECT SUMMARY Throughout recorded history, humans have used natural products for medicinal purposes. With the onset of modern analytical and pharmaceutical methods, the active ingredients in some of these “natural remedies” were identified and became foundational chemicals in drug development efforts. Among the numerous examples, aspirin (bark of the willow tree), capsaicin (chili peppers), and opioids (opium poppy plant) are notable for their analgesic properties. Similar to these other natural products, Cannabis sativa has long been used for medicinal purposes, including pain relief. The cannabis plant (Cannabis sativa/indica) contains over 100 phytocannabinoids as well as over 500 other identified chemicals, including the terpenoids that give cannabis its distinctive flavoring and aroma. Beyond 9-THC and CBD, however, difficulties in identifying, isolating and purifying minor phytocannabinoids in quantities sufficient for in vivo evaluation have hampered adequate investigation of potential therapeutic uses of individual phytocannabinoids. Recently, we have secured access to purified minor cannabinoids synthesized via a patented biosynthetic process in quantities that allow for preclinical in vivo testing. The goal of the proposed project is to provide a comprehensive evaluation of these compounds alone, and in planned combinations, to determine their potential efficacy as analgesics. In addition, we will conduct a parallel investigation of selected terpenes that have been identified in the cannabis plant. Novel analgesic strategies are needed to combat over-reliance on opioids and the resulting secondary consequences of dependence and morbidity/mortality.

项目总结在整个有记录的历史中，人类一直将天然产品用于医疗目的。随着……的到来现代分析和药学方法，其中一些“天然药物”的有效成分是确定并成为药物开发工作中的基础化学品。在众多的例子中，阿司匹林(柳树皮)、辣椒素(辣椒)和类阿片(罂粟植物)因其止痛特性。与这些其他天然产品类似，大麻长期以来一直被用作药用目的，包括止痛。大麻植物(大麻/印度大麻)含有100多种植物大麻素以及500多种其他已确定的化学物质，包括使大麻产生独特的风味和香气。然而，除了9-THC和CBD之外，识别、分离和提纯少量的植物大麻素的数量足以进行体内评估，这阻碍了足够的研究个别植物大麻素的潜在治疗用途。最近，我们获得了访问权限通过专利生物合成工艺合成的纯度较低的大麻类化合物，其数量允许临床前的活体试验。拟议项目的目标是提供对这些项目的全面评价单独和计划组合的化合物，以确定其作为镇痛剂的潜在疗效。此外, 我们将对大麻植物中已确定的部分萜烯进行平行调查。小说需要采取止痛战略，以打击对阿片类药物的过度依赖和由此产生的次要后果。依赖和发病率/死亡率。
