A group of patients with pneumonia caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were reported from China in December 2019. Although several antiviral drugs are widely tested, none of them has been approved as specific antiviral therapy for coronavirus disease 2019 (COVID-19). Accumulating evidence established a hyperinflammatory states or cytokine storm in COVID-19. Among these cytokines, IL-6 plays a key role in cytokine storm and can predict the adverse clinical outcomes and fatality in these patients. Based on the evidence of the significant role of IL-6 in cytokine storm, diabetes mellitus, and cardiovascular diseases as principal comorbidities, it seems that anti-cytokine therapy may be useful in patients with severe COVID-19 to reduce mortality. Recent studies demonstrated that herbal-derived natural products had immunosuppressive and anti-inflammatory properties and exhibited exceptional act on mediators of inflammation. Parthenolide is the principal sesquiterpene lactones and the main biologically active constituent Tanacetum parthenium (commonly known as feverfew) which has could significantly reduce IL-1, IL-2, IL-6, IL-8, and TNF-α production pathways established in several human cell line models in vitro and in vivo studies. Therefore, parthenolide may be one of the herbal candidates for clinical evaluation.
2019 年 12 月,中国报告了一组由严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)引起的肺炎患者。尽管有几种抗病毒药物被广泛测试,但没有一种被批准为冠状病毒病 2019(COVID-19)的特定抗病毒治疗方法。越来越多的证据表明 COVID-19 存在过度炎症状态或细胞因子风暴。在这些细胞因子中,IL-6 在细胞因子风暴中起着关键作用,并且可以预测这些患者的不良临床结局和死亡率。基于 IL-6 在细胞因子风暴、糖尿病和心血管疾病作为主要合并症中的重要作用,似乎针对细胞因子的治疗可能对严重 COVID-19 患者有用,以降低死亡率。最近的研究表明,草药衍生的天然产物具有免疫抑制和抗炎特性,并对炎症介质表现出特殊作用。小白菊内酯是倍半萜内酯的主要成分,也是白头翁(俗称小白菊)的主要生物活性成分,它可以显著减少体外和体内研究中几种人细胞系模型中 IL-1、IL-2、IL-6、IL-8 和 TNF-α 的产生途径。因此,小白菊内酯可能是临床评估的草药候选药物之一。
