plant is a potential target for the industrial production of phytochemicals that display applicability in pharmacy and medicine. The dry roots of contain up to 2 % of essential oil, the main component (up to 99 %) of which is carlina oxide [2-(3-phenylprop-1-ynyl)furan]. This compound shows multidirectional biological activity, including antibacterial and antifungal properties. Here, we evaluated the capacity of carlina oxide to inhibit the interaction between SARS-CoV-2 and its human receptor in vitro and . A bioluminescent immunoassay was used to study the interaction between the receptor binding domain (RBD) of viral spike protein and the human angiotensin-converting enzyme 2 (ACE2), which serves as a receptor for viral entry. A dose-effect relationship was demonstrated, and a concentration of carlina oxide causing half-maximal inhibition (IC) of the RBD:ACE2 interaction was determined to be equal to 234.2 µg/mL. Molecular docking suggested the presence of carlina oxide binding sites within the RBD and at the interface between RBD and ACE2. Finally, this study expands the list of potential applications of as a crop species.
植物是具有药用适用性的植物化学物质工业化生产的潜在目标。[植物名称]的干燥根含有高达2%的精油，其主要成分（高达99%）是氧化卡林内酯[2-(3-苯基丙-1-炔基)呋喃]。该化合物具有多向生物活性，包括抗菌和抗真菌特性。在此，我们评估了氧化卡林内酯在体外抑制严重急性呼吸综合征冠状病毒2（SARS-CoV-2）与其人类受体相互作用的能力。采用生物发光免疫测定法研究病毒刺突蛋白的受体结合域（RBD）与作为病毒进入受体的人类血管紧张素转换酶2（ACE2）之间的相互作用。证明了剂量效应关系，并且确定氧化卡林内酯导致RBD:ACE2相互作用半数最大抑制（IC）的浓度等于234.2μg/mL。分子对接表明在RBD内以及RBD与ACE2之间的界面处存在氧化卡林内酯结合位点。最后，本研究扩展了[植物名称]作为一种作物物种的潜在应用列表。
