The bioassay-guided fractionation from cultures of the actinobacterium Saccharothrix xinjiangensis Act24Zk, collected from the Caspian Sea beach in Iran led to the isolation of three new compounds, caerulomycin M (1), saccharopyrone (2), and saccharonoic acid (3), together with the known compound, caerulomycin A (4). Their structures were elucidated from HR-ESIMS and 1D and 2D NMR data. Compound 2 displayed moderate cytotoxic activity against the human cervix carcinoma HeLa cells KB3.1 with an IC50 value of 5.4âµM.
对从伊朗里海海滩收集的放线菌新疆糖丝菌 Act24Zk 培养物进行生物测定指导下的分离,分离出三种新化合物:青霉素 M (1)、糖吡喃酮 (2) 和糖酸酸 (3)与已知的化合物青霉素 A (4) 一起使用。它们的结构通过 HR-ESIMS 以及 1D 和 2D NMR 数据得到阐明。化合物 2 对人宫颈癌 HeLa 细胞 KB3.1 显示出中等的细胞毒活性,IC50 值为 5.4 µM。
