    • 摘要: 目的 基于网络药理学和分子对接技术,预测双黄连口服液治疗新型冠状病毒肺炎(Coronavirus Disease 2019,COVID-19)的有效成分及潜在作用机制.方法 利用TCMSP、Swiss Target Prediction等数据库检索双黄连口服液中药物的化学成分及作用靶点,运用GeneCards、CTD等数据库筛选COVID-19相关潜在靶标,通过Cytoscape 3.6.1软件构建"中药-成分-靶点-疾病"网络、PPI网络,利用BioGPS数据库进行关键靶点组织定位分析,通过GO及KEGG富集分析预测潜在作用机制,并将主要活性成分与SARS-CoV-23CL水解酶、ACE2及2019-nCoVRBD/ACE2-B0AT1complex进行分子对接验证.结果 共筛选出双黄连口服液中78个化学成分,629个成分靶点,330个COVID-19相关靶点,得到72个成分-疾病靶点,筛选出PTGS2、SRC、MMP2等28个关键靶点.GO富集共得到169个条目,主要涉及RNA转录、IL-6的表达与调控、ATP结合、血红素结合等.KEGG富集得到100条信号通路,主要为癌症相关通路、HIF-1、PI3K/Akt、TNF信号通路等.组织定位分析显示关键基因表达主要分布在在肺组织和免疫细胞中,分子对接结果显示双黄连口服液主要活性成分与3CLMpro、ACE2、complex结合较好,其中黄芩素、黄烷酮、木犀草素与3个蛋白结合能均较低,推测在治疗中发挥重要作用.结论 双黄连口服液可通过多成分-多靶点-多途径协同治疗COVID-19,其临床应用具有一定局限性,其机制可能是通过干预癌症相关通路、HIF-1、PI3K-Akt及TNF信号通路,发挥抗病毒、抗炎、抑制氧化应激、抑制细胞凋亡的作用,又可能与3CLMpro、ACE2、complex结合抑制病毒感染宿主细胞及干扰病毒复制增殖有关.

    • 摘要: Cyclodextrin ( CD ) based chiral stationary phases ( CSPs ) have simulated great attention due to their unique chiral recognition ability. Functionalized cyclodextrins bonded sili-ca gel as chiral stationary phases have been dramatically developed due to their chemical stabil-ity and solvent tolerability. To explore the functionalization of phenylcarbamoylated β-cyclodex-trin CSPs on their enantioselectivities,4-chloro-3-methylaniline and 5-chloro-2-methyl phenyl isocyanate were employed. Two CSPs have been thus developed by clicking the CD derivatives onto alkynylated silica support. They include per-4-chloro-3-methylphenylcarbamoylated β-cyclodextrin clicked CSP( CSP1)and per-5-chloro-2-methylphenylcarbamoylated β-cyclodextrin clicked CSP( CSP2),which have both electron-donating( methyl)and withdrawing( chlorine) groups in the phenylcarbamate moieties,but different locations. The CSPs were successfully characterized in terms of structure using nuclear magnetic resonance( NMR ),Fourier trans-form infrared spectroscopy( FT-IR ) and elementary analysis. Their enantioselectivities were evaluated in reversed-phase high performance liquid chromatography( HPLC). The comparison study on the enantioseparation of nine flavonoids with the two CSPs demonstrates the higher enantioselectivities of CSP1 over CSP2,because of the different locations of electron-donating (methyl)and withdrawing(chlorine)groups in the phenylcarbamate moieties of CD deriva-tives. The baseline enantioseparations achieved in water/methanol as mobile phase offered great potential for the CSPs to be used in practical application.%为了探讨功能基团对苯甲酰胺基-β-环糊精手性固定相手性拆分性能的影响,本文采用点击化学制备了两种手性固定相:全取代-4-氯-3-甲基苯甲酰氨基-6A-三唑基-β-环糊精键合硅胶手性固定相( CSP1)和全取代-5-氯-2-甲基苯甲酰氨基-6A-三唑基-β-环糊精键合硅胶手性固定相( CSP2)。利用核磁共振、红外光谱及元素分析等手段对固定相的结构进行了表征;在反相高效液相色谱条件下,通过对9种黄烷酮消旋体的拆分,对比研究了两种固定相的手性拆分性能。研究结果表明 CSP1的拆分性能优于 CSP2。这两种手性固定相仅在水与甲醇体系下即可实现对黄烷酮的手性拆分,展现了较好的应用前景。
