Citronellol (CT) is a monoterpene alcohol present in the essential oil of plants of the genus and exhibits diverse pharmacological activities. The aim of the current study was to investigate the hepatoprotective potential of CT against ethanol-induced toxicity in HepG2 cell lines. Silymarin (SIL) was used as a standard drug. MTT, crystal violet assay, DAPI, and PI staining were carried out to assess the effect of ethanol and CT on cell viability. RT-PCR determined the molecular mechanisms of hepatoprotective action of CT. CT ameliorated cell viability and restricted ethanol-induced cell death. DAPI and PI staining showed distinct differences in cell number and morphology. Less cell viability was observed in the diseased group obviously from strong PI staining when compared to the CT- and SIL-treated group. Moreover, CT showed downregulation of interleukin (IL-6), transforming growth factor-beta 1 (TGF-β1), collagen type 1 A 1 (COL1A1), matrix metalloproteinase-1 (MMP-1), tissue inhibitor of metalloproteinase-1 (TIMP-1) and glutathione peroxidase-7 (GPX-7) levels. Molecular docking studies supported the biochemical findings. It is concluded that the cytoprotective activity of CT against ethanol-induced toxicity might be explained by its anti-inflammatory, immunomodulatory, and collagen-regulating effects.
香茅醇(CT)是一种存在于某些植物属精油中的单萜醇,具有多种药理活性。本研究的目的是探讨CT对乙醇诱导的HepG2细胞系毒性的肝脏保护潜力。水飞蓟素(SIL)用作标准药物。采用MTT法、结晶紫测定法、DAPI和PI染色来评估乙醇和CT对细胞活力的影响。逆转录聚合酶链反应(RT-PCR)确定了CT肝脏保护作用的分子机制。CT改善了细胞活力并限制了乙醇诱导的细胞死亡。DAPI和PI染色显示细胞数量和形态存在明显差异。与CT和SIL处理组相比,病变组中明显可见较强的PI染色,细胞活力较低。此外,CT显示白细胞介素(IL-6)、转化生长因子-β1(TGF-β1)、I型胶原蛋白A1(COL1A1)、基质金属蛋白酶-1(MMP-1)、金属蛋白酶组织抑制剂-1(TIMP-1)和谷胱甘肽过氧化物酶-7(GPX-7)水平下调。分子对接研究支持了这些生化结果。得出的结论是,CT对乙醇诱导毒性的细胞保护活性可能归因于其抗炎、免疫调节和胶原蛋白调节作用。
