  The Discovery of Citral-Like Thiophenes in Fried Chicken

  摘要：

  The isomers of 3,7-dimethyl-2,6-octadienal, more commonly known together as citral, are two of the most notable natural compounds in the flavor and fragrance industry. However, both isomers are inherently unstable, limiting their potential use in various applications. To identify molecules in nature that can impart the fresh lemon character of citral while demonstrating stability under acidic and thermal conditions has been a major challenge and goal for the flavor and fragrance industry. In the study of fried chicken, several alkyl thiophenecarbaldehydes were identified by gas chromatography-mass spectrometry and gas chromatography-olfactometry that provided a similar citral-like aroma. The potential mechanism of formation in fried chicken is discussed. Furthermore, in order to explore the organoleptic properties of this structural backbone, a total of 35 thiophenecarbaldehyde derivatives were synthesized or purchased for evaluation by odor and taste. Certain organoleptic trends were observed as the length of the alkyl or alkenyl chain increased or when the chain was moved to different positions on the thiophene backbone. The 3-substituted alkyl thiophenecarbaldehydes, specifically 3-butyl-2-thiophenecarbaldehyde and 3-(3-methylbut-2-en-1-yl)-2-thiophenecarbaldehyde, exhibited strong citrus and citral-like notes. Several alkyl thiophenecarbaldehydes were tested in high acid stability trials (4 degrees C vs 38 degrees C) and outperformed citral both in terms of maintaining freshness over time and minimizing off-notes. Additional measurements were completed to calculate the odor thresholds for a select group of thiophenecarbaldehydes, which were found to be between 4.7-215.0 ng/L in air.

• Discovery of Inhibitors of <i>Escherichia coli</i> Methionine Aminopeptidase with the Fe(II)-Form Selectivity and Antibacterial Activity

  Methionine aminopeptidase (MetAP) is a promising target to develop novel antibiotics, because all bacteria express MetAP from a single gene that carries out the essential function of removing N-terminal methionine from nascent proteins. Divalent metal ions play a critical role in the catalysis, and there is an urgent need to define the actual metal used by MetAP in bacterial cells. By high throughput screening, we identified a novel class of catechol-containing MetAP inhibitors that display selectivity for the Fe(II)-form of MetAP. X-ray structure revealed that the inhibitor binds to MetAP at the active site with the catechol coordinating to the metal ions. Importantly, some of the inhibitors showed antibacterial activity at low micromolar concentration on Gram-positive and Gram-negative bacteria. Our data indicate that Fe(II) is the likely metal used by MetAP in the cellular environment, and MetAP inhibitors need to inhibit this metalloform of MetAP effectively to be therapeutically useful.
