Resumo:

Hydrogen-bonding catalytic reactions have gained great interest. Herein, a hydrogen-bond-assisted three-component tandem reaction for the efficient synthesis of N-alkyl-4-quinolones is described. This novel strategy features the first proof of polyphosphate ester (PPE) as a dual hydrogen-bonding catalyst and the use of readily available starting materials for the preparation of N-alkyl-4-quinolones. The method provides a diversity of N-alkyl-4-quinolones in moderate to good yields. The compound 4h demonstrated good neuroprotective activity against N-methyl-ᴅ-aspartate (NMDA)-induced excitotoxicity in PC12 cells.

Resumo:

β-Keto amides were used as convenient precursors to both 2-alkyl-4-quinolones and 2-alkyl-4-quinolone-3-carboxamides. The utility of this approach is demonstrated with the synthesis of fourteen novel and four known quinolone derivatives, including natural products of microbial origin such as HHQ and its C5-congener. Two compounds with high activity against S. aureus have been identified among the newly obtained quinolones, with MICs ≤ 3.12 and ≤ 6.25 µg/mL, respectively.

Resumo:

The alkyl-4-quinolones (AQs) are a class of metabolites produced primarily by members of the Pseudomonas and Burkholderia genera, consisting of a 4-quinolone core substituted by a range of pendant groups, most commonly at the C-2 position. The history of this class of compounds dates back to the 1940s, when a range of alkylquinolones with notable antibiotic properties were first isolated from Pseudomonas aeruginosa. More recently, it was discovered that an alkylquinolone derivative, the Pseudomonas Quinolone Signal (PQS) plays a key role in bacterial communication and quorum sensing in Pseudomonas aeruginosa. Many of the best-studied examples contain simple hydrocarbon side-chains, but more recent studies have revealed a wide range of structurally diverse examples from multiple bacterial genera, including those with aromatic, isoprenoid, or sulfur-containing side-chains. In addition to their well-known antimicrobial properties, alkylquinolones have been reported with antimalarial, antifungal, antialgal, and antioxidant properties. Here we review the structural diversity and biological activity of these intriguing metabolites.

Resumo:

Pseudomonas aentginosa is an opportunistic pathogen that produces an extensive arsenal of virulence determinants which are regulated in a cell-density dependent manner via quorum-sensing (QS). P. aeruginosa contains two sets of hierarchicallyarranged QS systems, known as las and rhl, which utilise acyl-homoserine lactone (AHL)-based signalling molecules. Recently, a novel class ofQS signal molecule has been discovered in P. aeruginosa, known as 2-alkyl-4-quinolones (AQs), arguably the most important of which are 2-heptyl-3-hydroxy-4-qunolone (PQS) and its immediate precursor 2-heptyl-4-quinolone (HHQ). The genes responsible for the synthesis and effect of AQs include pqsABCDE, pqsH and pqsR. The pqsABCDE genes are arranged in a five-gene operon, the expression of which is under the control of the transcriptional regulator, PqsR. PqsABCD direct the synthesis ofHHQ and PqsH converts this molecule into PQS. To explore AQ synthesis and action, two new bioluminescent biosensor strains were developed for the simple, rapid and inexpensive detection of AQs in bacterial cultures using thin layer chromatography (TLC) and microplate assays. On TLC, both bioreporters were capable of sensitive detection of PQS, HHQ, 2-nonyl-3hydroxy- 4-quinolone (C9-PQS), 2-nonyl-4-quinolone (NHQ) and 2-heptyl-4quinolone N-oxide (HHQNO). Using microplate assays, the bioreporters responded primarily to HHQ then PQS, but were also activated by other AQs in a dosedependent manner, most notably NHQ and C9-PQS. The biosensors were also used successfully to evaluate AQ production after 8 h in a series of P. aeruginosa mutant
