Coronaviruses are responsible for a growing economic, social and mortality burden, as the causative agent of diseases such as severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), avian infectious bronchitis virus (IBV) and COVID-19. However, there is a lack of effective antiviral agents for many coronavirus strains. Naturally existing compounds provide a wealth of chemical diversity, including antiviral activity, and thus may have utility as therapeutic agents against coronaviral infections. The PubMed database was searched for papers including the keywords coronavirus, SARS or MERS, as well as traditional medicine, herbal, remedy or plants, with 55 primary research articles identified. The overwhelming majority of publications focussed on polar compounds. Compounds that show promise for the inhibition of coronavirus in humans include scutellarein, silvestrol, tryptanthrin, saikosaponin B2, quercetin, myricetin, caffeic acid, psoralidin, isobavachalcone, and lectins such as griffithsin. Other compounds such as lycorine may be suitable if a therapeutic level of antiviral activity can be achieved without exceeding toxic plasma concentrations. It was noted that the most promising small molecules identified as coronavirus inhibitors contained a conjugated fused ring structure with the majority being classified as being polyphenols.

天然产物衍生的植物化学物质作为对抗冠状病毒的潜在药物:综述。



冠状病毒作为严重急性呼吸综合征(SARS)、中东呼吸综合征(MERS)、禽传染性支气管炎病毒(IBV)和COVID-19等疾病的病原体,造成了日益严重的经济、社会和死亡负担。然而,许多冠状病毒株缺乏有效的抗病毒药物。天然存在的化合物提供丰富的化学多样性,包括抗病毒活性,因此可用作对抗冠状病毒感染的治疗剂。对 PubMed 数据库中的论文进行了搜索,其中包括关键词冠状病毒、SARS 或 MERS,以及传统医学、草药、药物或植物,确定了 55 篇主要研究文章。绝大多数出版物都集中在极性化合物上。有望抑制人类冠状病毒的化合物包括灯盏乙素、西维甾醇、色胺酮、柴胡皂苷 B2、槲皮素、杨梅素、咖啡酸、补骨脂素、异补骨脂素和凝集素(如格里菲辛)。如果可以在不超过有毒血浆浓度的情况下达到治疗水平的抗病毒活性,则其他化合物(例如石蒜碱)可能是合适的。值得注意的是,最有希望作为冠状病毒抑制剂的小分子含有共轭稠环结构,其中大多数被归类为多酚。
