2-Heptylquinoline-4(1H)-one Chemical Properties,Usage,Production

Uses

2-Heptyl-4-quinolone is an intermediate in the synthesis of the Pseudomonas quinolone signal (PQS) that controls swarming by positively regulating phenazine production. 2-Heptyl-4-quinolone induces the production of the phenazine-1-carboxylic acid (PCA)[1].

Definition

ChEBI: A quinolone consisting of quinolin-4(1H)-one carrying a heptyl substituent at position 2.

General Description

HHQ belongs to 2-alkyl-4-quinolone compounds, which are lipophilic and are slightly soluble in water.

Biochem/physiol Actions

HHQ stimulates vesicle formation but not as much as PQS.
