  Enantiospecific Synthesis of N-Boc-Adda:  A Linear Approach

  摘要：

  Synthesis of the unusual amino acid (2S,3S,8S,9S)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyl-4,6 decadienoic acid (Adda), a unit of numerous cyanobacterial toxins, is described. Construction of the target molecule was achieved in 13 steps with an overall yield of 40%. The work is highlighted by a novel one-pot transformation from isoxazolidin-5-one intermediate 6 to the final product, a step that can also be used to form beta-amino acids.

  丝氨酸-苏氨酸磷酸酶抑制剂微囊藻毒素-LA的全合成

  摘要：

  由激酶和磷酸酶介导的可逆蛋白磷酸化是细胞的主要控制元件。有多种有毒的天然产物会抑制某些磷酸酶，从而破坏正常的生化途径。这些毒素可用于剖析与这些酶中的每一种相关的个体生化途径。本文描述了一种此类毒素的首次全合成，即环状七肽微囊藻毒素-LA。该合成具有收敛路线，可用于寻找选择性磷酸酶抑制剂的类似物制备。描述了一种不寻常的氨基酸 Adda 的新途径，它通过 Suzuki 偶联反应结合了有效的非对映选择性天冬氨酸烷基化和二烯合成。

  element of the cell. There is a diverse group of toxic natural products that inhibit certain phosphatases, thereby disrupting normal biochemical pathways. These toxins can be useful for dissecting the individual biochemical pathways associated with each of these enzymes. This Article describes the first total synthesis of one such toxin, the cyclic heptapeptide microcystin-LA. The synthesis features a convergent

  microcystin-LR analogues based on Adda [(2S,3S,8S,9S,4E,6E)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyldecadienoic acid] or its corresponding aldol precursor linked to a polypeptide moiety have been synthesised and assessed for their binding affinity by the monoclonal antibody mAb MC159, an anti-microcystin-LR mAb recently selected by us for the detection of microcystins through various immunoassay formats

  Total synthesis of the cyclic peptide hepatotoxin motuporin is described, including an efficient synthesis of the constituent amino acid Adda. Three strategies to motuporin are outlined with their relative strengths and weaknesses. Cyclization of the linear peptide precursor was found to proceed moderately well for peptides containing the N-methyldehydrobutyrine residue masked as a threonine, but significant C-terminal epimerization occurred in the presence of the dehydroamino acid. Replacement of the N-methyldehydrobutyrine residue by L-alanine was explored to assess the contribution of this dehydroamino acid to the biochemical activity of motuporin. Some epimerization also was observed during cyclization of the alanine-containing peptide. Synthetic motuporin and both isomers of 5-[L-Ala]-motuporin inhibit the activity of protein phosphatase-l (PP1) in rat adipocyte lysates with comparable IC50 values. These results indicate that the N-methyldehydrobutyrine residue is not essential for PP1 inhibition.
