Abstract

Depression is a serious psychiatric disorder with high prevalence, and the delayed onset of antidepressant effects remains a limitation in the treatment of depression. This study aimed to screen essential oils that have the potential for rapid-acting antidepressant development. PC12 and BV2 cells were used to identify essential oils with neuroprotective effects at doses of 0.1 and 1 µg/mL. The resulting candidates were treated intranasally (25 mg/kg) to ICR mice, followed by a tail suspension test (TST) and an elevated plus maze (EPM) after 30 min. In each effective essential oil, five main compounds were computationally analyzed, targeting glutamate receptor subunits. As a result, 19 essential oils significantly abolished corticosterone (CORT)-induced cell death and lactate dehydrogenase (LDH) leakage, and 13 reduced lipopolysaccharide (LPS)-induced tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6). From in vivo experiments, six essential oils decreased the immobility time of mice in the TST, in which Ramat. and Houtt. also increased time and entries into the open arms of the EPM. Four compounds including atractylon, α-curcumene, α-farnesene, and selina-4(14),7(11)-dien-8-one had an affinity toward GluN1, GluN2B, and Glu2A receptor subunits surpassed that of the reference compound ketamine. Overall, (Thunb.) DC and Ramat essential oils are worthy of further research for fast-acting antidepressants through interactions with glutamate receptors, and their main compounds (atractylon, α-curcumene, α-farnesene, and selina-4(14),7(11)-dien-8-one) are predicted to underlie the fast-acting effect.

摘要

抑郁症是一种患病率很高的严重精神疾病,而抗抑郁作用起效延迟仍然是抑郁症治疗中的一个局限。本研究旨在筛选具有开发速效抗抑郁药潜力的精油。使用PC12细胞和BV2细胞来鉴定在0.1和1μg/mL剂量下具有神经保护作用的精油。将所得候选物经鼻内给药(25mg/kg)给ICR小鼠,30分钟后进行悬尾试验(TST)和高架十字迷宫试验(EPM)。对每种有效的精油中的五种主要化合物进行了针对谷氨酸受体亚基的计算分析。结果,19种精油显著消除了皮质酮(CORT)诱导的细胞死亡和乳酸脱氢酶(LDH)泄漏,13种精油减少了脂多糖(LPS)诱导的肿瘤坏死因子α(TNF-α)和白细胞介素6(IL-6)。在体内实验中,六种精油减少了小鼠在TST中的不动时间,其中[具体植物1]和[具体植物2]还增加了小鼠在EPM开放臂中的停留时间和进入次数。包括苍术酮、α-姜黄烯、α-法呢烯和柳杉-4(14),7(11)-二烯-8-酮在内的四种化合物对GluN1、GluN2B和Glu2A受体亚基的亲和力超过了参考化合物氯胺酮。总体而言,[具体植物3]精油和[具体植物4]精油通过与谷氨酸受体相互作用,在速效抗抑郁药方面值得进一步研究,并且预计它们的主要化合物(苍术酮、α-姜黄烯、α-法呢烯和柳杉-4(14),7(11)-二烯-8-酮)是速效作用的基础。 (注:原文中部分植物名称未给出完整拉丁名,翻译时用[具体植物X]代替,需根据实际完整名称进行准确翻译)
