  The End of an Old Hypothesis: The Pseudomonas Signaling Molecules 4-Hydroxy-2-Alkylquinolines Derive from Fatty Acids, Not 3-Ketofatty Acids

  摘要：

  Groups of pathogenic bacteria use diffusible signals to regulate their virulence in a concerted manner. Pseudomonas aeruginosa uses 4-hydroxy-2-alkylquinolines (HAQs), including 4-hydroxy-2-heptylquinoline (HHQ) and 3,4-dihydroxy-2-heptylquinoline (PQS), as unique signals. We demonstrate that octanoic acid is directly incorporated into HHQ. This finding rules out the long-standing hypothesis that 3-ketofatty acids are the precursors of HAQs. We found that HAQ biosynthesis, which requires the PqsABCD enzymes, proceeds by a two-step pathway: (1) PqsD mediates the synthesis of 2aminobenzoylacetate (2-ABA) from anthraniloylcoenzyme A (CoA) and malonyl-CoA, then (2) the decarboxylating coupling of 2-ABA to an octanoate group linked to PqsC produces HHQ, the direct precursor of PQS. PqsB is tightly associated with PqsC and required for the second step. This finding uncovers promising targets for the development of specific antivirulence drugs to combat this opportunistic pathogen.

• Gold-catalyzed cyclization of 1-(2′-azidoaryl) propynols: synthesis of polysubstituted 4-quinolones

  An unprecedented gold-catalyzed procedure for the synthesis of polysubstituted 4-quinolones from 1-(2'-azidoaryl) propynols is described. The reaction undergoes an intramolecular nucleophilic attack of the azide group to the Au-activated triple bonds in a 6-endo-dig manner and subsequent gold-assisted expulsion of N2 to furnish an α-imino gold carbene intermediate, which triggers a 1,2-carbon migration

  2-Heptyl-3-hydroxy-4-quinolone (PQS) and its precursor 2-heptyl-4-quinolone (HHQ) are key signalling molecules of the important nosocomial pathogen Pseudomonas aeruginosa. We have recently reported an interkingdom dimension to these molecules, influencing key virulence traits in a broad spectrum of microbial species and in the human pathogenic yeast Candida albicans. For the first time, targeted chemical derivatisation of the C-3 position was undertaken to investigate the structural and molecular properties underpinning the biological activity of these compounds in P. aeruginosa, and using Bacillus subtilis as a suitable model system for investigating modulation of interspecies behaviour.
