Industrial hemp is a multiuse crop whose phytocomplex includes terpenophenolics and flavonoids. In the present study, the phenolic and terpenophenolic compounds were assayed in the water extract of the hemp variety Futura 75. Protective effects were also investigated in human fibroblast and keratinocytes and isolate mouse skin specimens, which were exposed to hydrogen peroxide and/or to the extract (1-500 µg/mL). The results of phytochemical analysis suggested the cannabidiol, cannabidiolic acid and rutin as the prominent phytocompounds. In the in vitro system represented by human keratinocytes and fibroblasts, the hemp extract was found to be able to protect cells from cytotoxicity and apoptosis induced by oxidative stress. Moreover, modulatory effects on IL-6, a key mediator in skin proliferation, were found. In isolated rat skin, the extract reduced hydrogen peroxide-induced l-dopa turnover, prostaglandin-E2 production and the ratio kynurenine/tryptpophan, thus corroborating anti-inflammatory/antioxidant effects. The in silico docking studies also highlighted the putative interactions between cannabidiol, cannabidiolic acid and rutin with tyrosinase and indoleamine-2,3-dioxygenase, involved in l-dopa turnover and tryptophan conversion in kynurenine, respectively. In conclusion, the present findings showed the efficacy of hemp water extract as a skin protective agent. This could be partly related to the extract content in cannabidiol, cannabidiolic acid and rutin.
工业大麻是一种多用途作物,其植物复合物包括萜酚类化合物和黄酮类化合物。在本研究中,对大麻品种Futura 75的水提取物中的酚类和萜酚类化合物进行了分析。还在人成纤维细胞和角质形成细胞以及分离的小鼠皮肤标本中研究了其保护作用,这些细胞和标本暴露于过氧化氢和/或提取物(1 - 500μg/mL)中。植物化学分析结果表明,大麻二酚、大麻二酚酸和芦丁是主要的植物化合物。在以人角质形成细胞和成纤维细胞为代表的体外系统中,发现大麻提取物能够保护细胞免受氧化应激诱导的细胞毒性和细胞凋亡。此外,还发现了对皮肤增殖的关键介质白细胞介素-6的调节作用。在分离的大鼠皮肤中,提取物降低了过氧化氢诱导的左旋多巴周转率、前列腺素-E2的产生以及犬尿氨酸/色氨酸的比值,从而证实了其抗炎/抗氧化作用。计算机对接研究还突出了大麻二酚、大麻二酚酸和芦丁与酪氨酸酶和吲哚胺-2,3-双加氧酶之间的假定相互作用,它们分别参与左旋多巴周转率和色氨酸向犬尿氨酸的转化。总之,本研究结果表明大麻水提取物作为皮肤保护剂的有效性。这可能部分与提取物中大麻二酚、大麻二酚酸和芦丁的含量有关。
