Two new peptaibols, namely microbacterins A (1) and B (2), were isolated from the deep sea inhabited actinomycete Microbacterium sediminis spp. nov. YLB-01(T). The sequences of the amino acid residues were determined on the basis of intensive NMR and ESI-MS/MS spectroscopic analysis, in addition to the Marfey's method and CD and optical rotation data for the configurational assignment. Both 1 and 2 exhibited significant cytotoxic activities against a panel of human tumor cell lines.
两种新的缩肽类化合物，即 microbacterins A（1）和 B（2），从深海栖居放线菌 Microbacterium sediminis spp. nov. YLB-01(T)中分离得到。氨基酸残基序列是基于密集的 NMR 和 ESI-MS/MS 光谱分析，以及 Marfey 方法和 CD 及旋光数据确定的，用于构型分配。1 和 2 均对一组人类肿瘤细胞系表现出显著的细胞毒性活性。
