mangrove ecosystem is a rich resource for the discovery of actinomycetes with potential applications in pharmaceutical science. Besides the genus Streptomyces, Micromonospora is also a source of new bioactive agents. We screened Micromonospora from the rhizosphere soil of mangrove plants in Fujian province, China, and 51 strains were obtained. Among them, the extracts of 12 isolates inhibited the growth
红树林生态系统是发现放线菌的丰富资源,在制药科学中具有潜在的应用。除链霉菌属外,微单孢菌也是新生物活性剂的来源。我们从中国福建省红树林植物的根际土壤中筛选了小单孢菌,并获得了51株。其中,12种分离物的提取物抑制人肺癌A549细胞的生长。菌株110B表现出更好的细胞毒活性,并对其生物活性成分进行了研究。因此,三种新的异黄酮苷,黄豆苷元4'-(2-脱氧-α-1-呋喃果糖苷)(1),黄豆苷元7-(2-脱氧-α-1-1-呋喃二糖苷)(2)和黄豆苷元-4从菌株110B的发酵液中分离出′,7-二-(2-脱氧-α-1-呋喃果糖苷)(3)。通过光谱方法确定了新化合物的结构,包括1D和2D核磁共振(NMR)和高分辨率电喷雾电离质谱(HR-ESIMS)。改变培养基的实验结果表明,这些新化合物是a。aurantiaca 110B菌株的微生物生物转化产物。这三种化合物对人肺癌细胞系A549,肝细胞肝癌细胞系He
