  Cyclic Depsipeptides, Grassypeptolides D and E and Ibu-epidemethoxylyngbyastatin 3, from a Red Sea Leptolyngbya Cyanobacterium

  摘要：

  Two new grassypeptolides and a lyngbyastatin analogue, together with the known dolastatin 12, have been isolated from field collections and laboratory cultures of the marine cyanobacterium Leptolyngbya sp. collected from the SS Thistlegorm shipwreck in the Red Sea. The overall stereostructures of grassypeptolides D (1) and E (2) and Ibu-epidemethoxylyngbyastatin 3 (3) were determined by a combination of 1D and 2D NMR experiments, MS analysis, Marfey's methodology, and HPLC-MS. Compounds 1 and 2 contain 2-methyl-3-aminobutyric acid and 2-aminobutyric acid, while biosynthetically distinct 3 contains 3-amino-2-methylhexanoic acid and the beta-keto amino acid 4-amino-2,2-dimethyl-3-oxopentanoic acid (Ibu). Grassypeptolides D (1) and E (2) showed significant cytotoxicity to HeLa (IC50 = 335 and 192 nM, respectively) and mouse neuro-2a blastoma cells (IC50 = 599 and 407 nM, respectively), in contrast to Ibu-epidemethoxylyngbyastatin 3 (neuro-2a cells, IC50 > 10 mu M) and dolastatin 12 (neuro-2a cells, IC50 > 1 mu M).

  Two related peptide metabolites, one a cyclic depsipeptide, hoiamide B (2), and the other a linear lipopeptide, hoiamide C (3), were isolated from two different collections of marine cyanobacteria obtained in Papua New Guinea. Their structures were elucidated by combining various techniques in spectroscopy, chromatography, and synthetic chemistry. Both metabolites belong to the unique hoiamide structural

  从巴布亚新几内亚获得的两个不同的海洋蓝细菌集合中分离出两种相关的肽代谢物，一种是环状缩酚肽，hoiamide B ( 2 )，另一种是线性脂肽，hoiamide C ( 3 )。通过结合光谱学、色谱法和合成化学的各种技术，阐明了它们的结构。两种代谢物都属于独特的 hoiamide 结构类别，其特征是具有乙酸盐延伸和S-腺苷甲硫氨酸修饰的异亮氨酸单元、由两个 α-甲基化噻唑啉和一个噻唑组成的中心三杂环系统，以及高度氧化和甲基化的 C-15 聚酮化合物单元。在新皮质神经元中，环缩肽2刺激钠流入并抑制自发 Ca 2+振荡，EC 50值分别为 3.9 μM 和 79.8 nM，而3在这些测定中没有显着影响。

  Bioassay-guided fractionation of two cyanobacterial extracts from Papua New Guinea has yielded hoiamide D in both its carboxylic acid and conjugate base forms. Hoiamide D is a polyketide synthase (PKS)/non-ribosomal peptide synthetase (NRPS)-derived natural product that features two consecutive thiazolines and a thiazole, as well as a modified isoleucine residue. Hoiamide D displayed inhibitory activity against p53/MDM2 interaction (EC50 = 4.5 mu M), an attractive target for anticancer drug development. (C) 2011 Elsevier Ltd. All rights reserved.
