Synthesis, Structure, and Tandem Mass Spectrometric Characterization of the Diastereomers of Quinic Acid [PDF]
Journal of Agricultural and Food Chemistry, 2016 (−)-Quinic acid possess eight possible stereoisomers, which occur both naturally and as products of thermal food processing. In this contribution, we have selectively synthesized four isomers, namely, epi-quinic acid, muco-quinic acid, cis-quinic acid ...

A synthesis of
Here, we report an efficient synthesis of l-(+)-quinic acid from the natural product d-(–)-quinic acid in a 12-step sequence. The key steps involve the kinetic controlled selective protection of a lactone intermediate and the inversion of two stereocentres: the C-3 and C-5 hydroxyl of the quinic acid core using optimized oxidation–reduction conditions.

New stereoisomers of quinic acid and their lactones
Liebigs Annalen Der Chemie, 1991AbstractHeating of (−)‐quinic acid [(−)‐1] at reflux temperature with 90% acetic acid/concd. H2SO4 (67/1) yields a mixture of six stereoisomeric quinic acids (four meso forms and two pairs of enantiomers), four γ‐quinides (four pairs of enantiomers), and three δ‐quinides (two meso forms and one enantiomeric pair).

BACKGROUND Western flower thrips are considered the major insect pest of horticultural crops worldwide, causing economic and yield loss to Solanaceae crops. The eggplant (Solanum melongena L.) resistance against thrips remains largely unexplored.

In-silico analysis reveals Quinic acid as a multitargeted inhibitor against Cervical Cancer
Journal of Biomolecular Structure and Dynamics, 2022The cervix is the lowermost part of the uterus that connects to the vagina, and cervical cancer is a malignant cervix tumour. One of this cancer’s most important risk factors is HPV infection.

Antioxidant metabolism induced by quinic acid. increased urinary excretion of tryptophan and nicotinamide [PDF]
Phytotherapy Research, 2009 For over 50 years, hippuric/quinic acids were believed to have no biological efficacy. Here data are presented to support the hypothesis that quinic acid is not responsible for any efficacy, but rather that quinic acid nutritionally supports the ...

Biochimica et Biophysica Acta, 1954
Abstract Quinic dehydrogenase, which catalyzes the conversion of quinic acid to 5-dehydroquinic acid, has been extracted from cells of an Aerobacter mutant and partially purified. The enzyme is DPN-specific. With initial extracts TPN also promotes the reactin, but its activity has been shown to be due to coupling with DPN by pyridine nucleotide ...
