<i>Cis</i>-2-decenoic acid modulates <i>Pseudomonas aeruginosa</i> virulence through a noncanonical transcriptional regulator. [PDF]

mLife
Abstract Diffusible signal factor (DSF)‐family quorum sensing (QS) signals are widely utilized by many pathogenic bacteria to modulate various biological functions and virulence. Previous studies showed that cis‐2‐decenoic acid (cis‐DA) is involved in the modulation of biofilm dispersion in Pseudomonas aeruginosa, but the regulatory mechanism is ...

Down-regulation of aquaporin 9 gene transcription by 10-hydroxy-2-decenoic acid: A major fatty acid in royal jelly. [PDF]

Food Sci Nutr, 2019
Abstract10‐Hydroxy‐trans‐2‐decenoic acid (10H2DA) is a unique lipid component of royal jelly produced by worker honeybees that exerts insulin‐like effects. We herein investigated the effects of 10H2DA on the gene expression of aquaporin 9 (AQP9), which functions as a glycerol transporter in the liver, to clarify whether 10H2DA modulates energy ...

Synthesis of 10-Hydroxy-2-decenoic Acid (Royal Jelly Acid) from the Butadiene Telomer [PDF]

Bulletin of the Chemical Society of Japan, 1977
Abstract Ethyl 2-acetyl-4,9-decadienoate obtained by palladium catalyzed reaction of butadiene and ethyl acetoacetate was converted to 4,9-decadienoate. Hydroboration of the terminal olefin gave 10-hydroxy-4-decenoate. After hydrogenation and protection of the hydroxyl group, the double bond was created at the conjugated position by ...
