Abstract

is a kind of edible fungus widely grows in the north temperate zone, which shows various medicinal properties. Due to the complexity of chemical constitutes of this species, few investigations have acquired a comprehensive configuration for the chemical profile of it. In this study, a strategy based on ultra-high performance liquid chromatography (UPLC) combined with Orbitrap mass spectrometer (MS) was established for rapidly characterizing various chemical components in . Through the summarized MS/MS fragmentation patterns of reference compounds and systematic identification strategy, a total of 110 components attributed to six categories were identified for the first time. Moreover, allergic rhinitis (AR) is a worldwide inflammatory disease seriously affecting human health, and the development of drugs to treat AR has been a topic of interest. It has been reported that the extracts of showed obvious inhibitory effects on degranulation of mast cell- and allergen-induced IgE and proinflammatory mediators, but the active components and specific mechanism were still not clear. Src family kinases (SFKs) participate in the initial stage of allergy occurrence, which are considered the targets of AR treatment. Herein, on the basis of that self-built chemical database, virtual screening was applied to predict the potential SFKs inhibitors in , using known crystal structures of Hck, Lyn, Fyn, and Syk as receptors, followed by the anti-inflammatory activity evaluation for screened hits by intracellular calcium mobilization assay. As results, sparoside A was directly confirmed to have strong anti-inflammatory activity with an IC value of 5.06 ± 0.60 μM. This study provides a useful elucidation for the chemical composition of , and demonstrated its potential inhibitory effects on AR, which could promote the research and development of effective agents from natural resources.

摘要

是一种广泛生长在北温带的食用真菌,具有多种药用特性。由于该物种的化学成分复杂,很少有研究对其化学成分进行全面的分析。本研究建立了一种基于超高效液相色谱(UPLC)结合轨道阱质谱(MS)的策略,用于快速分析 的各种化学成分。通过对参考化合物的 MS/MS 碎片模式进行总结和系统的鉴定策略,首次鉴定了 110 种成分,归属于 6 类。此外,过敏性鼻炎(AR)是一种影响全球人类健康的炎症性疾病,开发治疗 AR 的药物一直是一个热门话题。据报道, 的提取物对肥大细胞脱颗粒和过敏原诱导的 IgE 和促炎介质具有明显的抑制作用,但活性成分和具体机制尚不清楚。Src 家族激酶(SFKs)参与过敏发生的初始阶段,被认为是 AR 治疗的靶点。在此基础上,基于自建的化学数据库,采用虚拟筛选方法预测 中的潜在 SFKs 抑制剂,以 Hck、Lyn、Fyn 和 Syk 的已知晶体结构作为受体,然后通过细胞内钙动员测定对筛选出的化合物进行抗炎活性评价。结果表明,裂环烯醚萜苷 A 直接证实具有较强的抗炎活性,IC 值为 5.06±0.60μM。本研究为 的化学成分提供了有用的解析,并证明了其对 AR 的潜在抑制作用,这可能促进了从天然资源中开发有效药物的研究和开发。
