  Lahorenoic Acids A–C, ortho-Dialkyl-Substituted Aromatic Acids from the Biocontrol Strain Pseudomonas aurantiaca PB-St2

  摘要：

  Three new aromatic acids, named lahorenoic acids A (1), B (2), and C (3), have been isolated along with the known compounds phenazine-1-carboxylic acid (4), 2-hydroxyphenazine-1-carboxylic acid (5), 2-hydroxyphenazine (6), 2,8-dihydroxyphenazine (7), cyclo-Pro-Tyr (8), cyclo-Pro-Val (9), cyclo-Pro-Met (10), and WLIP (11) and characterized from the biocontrol strain Pseudomonas aurantiaca PB-St2. The structures of these compounds were deduced by 1D and 2D NMR spectroscopic and mass spectral data interpretation. Compounds 2, 4, and 7 showed moderate antibacterial activity against mycobacteria and other Gram-positive bacteria, while 4 was also found to exhibit cytotoxic and antifungal properties.

  One new phenylalanine derivative 4'-OMe-asperphenamate (1), along with one known phenylalanine derivative (2) and two new cytochalasins, aspochalasin A1 (3) and cytochalasin Z24 (4), as well as eight known cytochalasin analogues (5-12) were isolated from the fermentation broth of Aspergillus elegans ZJ-2008010, a fungus obtained from a soft coral Sarcophyton sp. collected from the South China Sea.

  unprecedented linaridins bearing nine d-amino acids, which are uncommon in RiPP natural products and are the first reported in the linaridin subfamily. Whole genome mining of GSL-6C did not reveal any homologues of the reported genes responsible for amino acid epimerization in RiPPs, inferring new epimerases may be involved in the conversion of l- to d-amino acids. In addition, the N-oxide and dimethylimidazolidin-4-one

  Herein is reported the development of a new process to manufacture (S)-pregabalin. The method comprises six steps, run under the catalysis of a recyclable polymer bound phase transfer catalyst, and afforded (S)-pregabalin in overall 54% yield, starting from building blocks acetylacetone, isovaleraldehyde, and nitromethane.
• Synthesis of poly (γ-glutamic acid) and heterologous expression of pgsBCA genes

  The genes required for synthesis of poly (gamma-glutamic acid) (gamma-PGA) were cloned from Bacillus licheniformis NK-03, a strain isolated from fermented food, natto. There were three open reading frames pgsB, pgsC, pgsA in the cloned fragment, all of which were greatly similar with those from typical Bacillus subtilis strains. The alignment of deduced amino acid sequences showed that PgsC was the most conservative part in PgsBCA. Recombinant plasmid pXMJ19-PGS was constructed by a shuttle vector pXMJ19, and it was successfully transformed and expressed in the recombinant strains of Escherichia coli JM109 and Corynebacterium glutamicum ATCC13032, respectively. Expression of pgsBCA in C. glutamicum indicated that it could synthesize gamma-PGA with a yield of 0.69 g/L and 97% proportion of L-glutamate monomer in the absence of glutamic acid. The results suggest that gamma-PGA biosynthesis directly from glucose by genetic engineering is feasible and significant. (C) 2010 Elsevier B.V. All rights reserved.
