  摘要：

  通过对合成的马菲氏衍生物和天然产物水解物的马菲氏衍生物进行 HPLC 和 TLC 比较，我们确定了 N-甲基异亮氨酸和 N-甲基苏氨酸这两个氨基酸残基的绝对构型。结果发现，这两个 N-甲基化残基的手性中心构型与常见的未甲基化 l-氨基酸的手性中心构型相同。

  Coibamide A, a Potent Antiproliferative Cyclic Depsipeptide from the Panamanian Marine Cyanobacterium Leptolyngbya sp.

  摘要：

  Coibamide A (1) is a new, potent antiproliferative depsipeptide which was isolated from a marine Leptolyngbya cyanobacterium collected from the Coiba National Park, Panama. The planar structure of I was elucidated by a combination of NMR spectroscopy and mass spectrometry. Exhaustive 1 D and 2D NMR spectroscopy included natural abundance (15)N and variable temperature experiments; mass spectrometry included TOF-ESI-MS(n) and FT-MS(n) experiments, Chemical degradation followed by chiral HPLC- and GC-MS analyses was used to assign the absolute configuration of 1. This highly methylated cyclized depsipeptide exhibited an unprecedented selectivity profile in the NCl 60 cancer cell line panel and appears to act via a novel mechanism.

  The structures of the amphiphilic peptide antibiotics herbicolin A and B were determined by application of physical methods, chemical degradation, and partial syntheses. Herbicolin B is a lipodepsinonapeptide with the sequence DH-Abu-L-Thr-D-aThr-D-Leu-Gly-D-Gln-Gly-N-Me-L-aThr-L-Arg (DH-Abu = 2,3-dehydro-α-aminobutyric acid). The C-terminal Arg residue forms a lactone ring with the hydroxy group of

  通过应用物理方法，化学降解和部分合成，确定了两亲性肽类抗生素草本植物A和B的结构。Herbicolin B是一种具有序列DH-Abu-L-Thr-D-aThr-D-Leu-Gly-D-Gln-Gly- N -Me-L-aThr-L-Arg（DH-Abu = 2， 3-脱氢-α-氨基丁酸）。C末端的Arg残基与L-Thr的羟基形成内酯环，而N末端被（R）-3-羟基十四烷酸残基酰化。草本植物素A的主要成分与草本植物素B的不同之处在于，其他的D-葡萄糖部分以1-α-糖苷键与3-羟基十四烷酸残基连接。因此，草药草素A构成了迄今已知的第一种糖脂去氧核糖肽抗生素。

  The novel cyclic depsipeptides papuamides A (1), B (2), C (3), and D (4) have been isolated from Papua New Guinea collections of the sponges Theonella mirabilis and Theonella swinhoei. Their structures were determined by a combination of spectroscopic analysis and chemical degradation and derivatization studies. In addition to glycine, alanine, and threonine, these peptides contain a number of unusual amino acids including 3,4-dimethylglutamine, beta-methoxytyrosine, 3-methoxyalanine, and 2,3-diaminobutanoic acid or 2-amino-2-butenoic acid residues. Papuamides A-D (1-4) are also the first marine-derived peptides reported to contain 3-hydroxyleucine and homoproline residues. These peptides also contain a previously undescribed 2,3-dihydroxy-2,6,8-trimethyldeca-(4Z,6E)-dienoic acid moiety N-linked to a terminal glycine residue. Papuamides A (1) and B (2) inhibited the infection of human T-lymphoblastoid cells by HIV-1(RF) in vitro with an EC50 of approximately 4 ng/mL. Compound 1 was also cytotoxic against a panel of human cancer cell lines with a mean IC50 of 75 ng/mL.

  We report the full structural determination of the depsipeptide petriellin A. The absolute configuration of the amino acid residues, N-methyl isoleucine and N-methyl threonine, have been determined by a combination of HPLC and TLC comparison of synthetic Marfey’s derivatives and Marfey’s derivatives of the natural product hydrolysate. The configuration of the chiral centres in these two N-methylated residues was found to be the same as those of the common unmethylated l-amino acids.
