Cannabidiol (CBD) is the second most abundant component of the Cannabis plant and is known to have effects distinct from Δ -tetrahydrocannabinol (THC). Many studies that examined the behavioral effects of CBD concluded that it lacks the psychotomimetic effects attributed to THC. However, CBD was shown to have a broad spectrum of effects on several conditions such as anxiety, inflammation, neuropathic pain, and epilepsy. It is currently thought that CBD engages different targets and hence CBD's effects are thought to be due to multiple molecular mechanisms of action. A well-accepted set of targets include GPCRs and ion channels, with the serotonin 5-HT receptor and the transient receptor potential cation channel TRPV1 channel being the two main targets. CBD has also been thought to target G protein-coupled receptors (GPCRs) such as cannabinoid and opioid receptors. Other studies have suggested a role for additional GPCRs and ion channels as targets of CBD. Currently, the clinical efficacy of CBD is not completely understood. Evidence derived from randomized clinical trials, in vitro and in vivo models and real-world observations support the use of CBD as a drug treatment option for anxiety, neuropathy, and many other conditions. Hence an understanding of the current status of the field as it relates to the targets for CBD is of great interest so, in this review, we include findings from recent studies that highlight these main targets.
大麻二酚(CBD)是大麻植物中第二丰富的成分,已知具有与 Δ-四氢大麻酚(THC)不同的作用。许多研究检查了 CBD 的行为效应,得出的结论是它缺乏归因于 THC 的致幻作用。然而,CBD 对多种疾病有广泛的影响,如焦虑、炎症、神经痛和癫痫。目前认为 CBD 与不同的靶点结合,因此 CBD 的作用被认为是由于多种分子作用机制。一组公认的靶点包括 G 蛋白偶联受体(GPCRs)和离子通道,5-羟色胺 5-HT 受体和瞬时受体电位阳离子通道 TRPV1 通道是两个主要靶点。CBD 也被认为针对大麻素和阿片受体等 G 蛋白偶联受体(GPCRs)。其他研究表明,CBD 还可以作为其他 GPCRs 和离子通道的靶点。目前,CBD 的临床疗效还不完全清楚。来自随机临床试验、体外和体内模型以及真实世界观察的证据支持将 CBD 用作治疗焦虑症、神经病变和许多其他疾病的药物选择。因此,了解与 CBD 靶点相关的领域的现状非常重要,因此,在这篇综述中,我们包括了最近研究的结果,这些结果突出了这些主要靶点。
