8-HQA adjusts the number and diversity of bacteria in the gut microbiome of Spodoptera littoralis

Frontiers in Microbiology, 2023
Quinolinic carboxylic acids are known for their metal ion chelating properties in insects, plants and bacteria. The larval stages of the lepidopteran pest, Spodoptera littoralis, produce 8-hydroxyquinoline-2-carboxylic acid (8-HQA) in high concentrations

Quinolinic Acid: Neurotoxin or Oxidative Stress Modulator? [PDF]

International Journal of Molecular Sciences, 2013
Quinolinic acid (2,3-pyridinedicarboxylic acid, QUIN) is a well-known neurotoxin. Consequently, QUIN could produce reactive oxygen species (ROS). ROS are generated in reactions catalyzed by transition metals, especially iron (Fe). QUIN can form coordination complexes with iron.
