摘要/Abstract

摘要：

从西太平洋深海热液沉积物来源的镰刀菌SCSIO 06196中分离鉴定了6个色原酮类化合物(1~6), 通过核磁共振光谱、质谱及旋光等多种分析测试方法确定了色原酮类化合物的结构。抗病毒活性筛选发现, 化合物1~3展示出显著的抗肠道病毒EV-71活性, IC₅₀分别达到26.7μmol•L^-1、19.8μmol•L^-1和22.0μmol•L^-1(阳性对照药物利巴韦林为177μmol•L^-1)。此外, 化合物1还显示出弱的抗流感病毒H3N2活性, IC₅₀为8.6μmol•L^-1(阳性对照药物达菲为18.5nmol•L^-1)。

Abstract:

Six chromone derivatives (1 ~ 6) were identified from the fungus Fusarium sp. SCSIO 06196 isolated from deep-sea hydrothermal vent environments in the Western Pacific. Their structures were elucidated mainly by extensive Nuclear Magnetic Resonance (NMR) spectroscopic, mass spectrometric (MS) and rotational analysis. Antiviral activities of the compounds 1 ~ 6 were tested. Among these compounds, compounds 1 ~ 3 exhibited significant in vitro anti-enterovirus 71 (EV-71) activities with IC₅₀ values of 26.7, 19.8, and 22.0 μmol•L^-1, respectively (IC₅₀=177 μmol•L^-1, Ribavirin). In addition, compound 1 showed weak antiviral activity against the H3N2 influenza virus with IC₅₀ value of 8.6 μmol•L^-1 (IC₅₀=18.5 nmol•L^-1, Tamiflu).

Key words: deep-sea hydrothermal vent, polyketide, anti-EV 71 activity, anti-H3N2 activity
