<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 ...

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 ...
