Quinolone antibacterials

2-heptyl-3-hydroxy-4-quinolone can function as an intercellular signal . Application Quorum sensing is a signaling system used by bacteria to coordinate activity based upon their population density.

Application 4-Hydroxy-1-methyl-2(1 H )-quinolone was used as nucleophile in electrochemical oxidation of catechols and the reaction was studied by cyclic voltammetry and controlled-potential coulometry . It was used in ceric ammonium

Ethyl 4-quinazolone-2-carboxylate is a quinazoline derivative. It can be synthesized from anthranilamide and ethyl oxalate.
