06CM016, together with a new (4) and three known compounds. Structures of the new metabolites were elucidated by one-dimensional ((1)H and (13)C) and 2D NMR (COSY, HMQC and HMBC) and HR-TOF-MS analyses. All the metabolites exhibited significant antimicrobial activity. A plausible mechanism was proposed for compound 3's formation from amicetin.
从海洋衍生的放线菌罗氏链霉菌06CM016中分离出一种具有新型5-(羟甲基)-5-甲基
咪唑啉丁-4-酮亚结构的核苷类似物RocheicOSide A(3),以及一种新的(4)和三种已知化合物。通过一维((1)H和(13)C)和2D NMR(COSY,HMQC和HMBC)和HR-TOF-MS分析阐明了新代谢物的结构。所有代谢物均显示出显着的抗菌活性。有人提出了从阿米斯汀形成化合物3的合理机制。
