Identification and Quantitation of Reaction Products from Quinic Acid, Quinic Acid Lactone, and Chlorogenic Acid with Strecker Aldehydes in Roasted Coffee

Journal of Agricultural and Food Chemistry, 2021
To gain comprehensive insight into the interactions of key coffee odorants, like the Strecker aldehydes, acetaldehyde, propanal, methylpropanal, 2- and 3-methylbutanal, and methional, and the nonvolatile fraction of coffee, an untargeted metabolomics approach was applied.

A synthesis of l-(+)-quinic acid from d-(–)-quinic acid

Canadian Journal of Chemistry, 2023
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.

Bioavailability and metabolism of chlorogenic acids (acyl‐quinic acids) in humans

Comprehensive Reviews in Food Science and Food Safety, 2020
Abstract Acyl‐quinic acids (chlorogenic acids) are produced by many plants, including fruits, vegetables, and herbal remedies, with coffee and maté particularly rich dietary sources. Epidemiological and intervention studies suggest that they can reduce the risk of developing type 2 diabetes and cardiovascular ...

In-silico analysis reveals Quinic acid as a multitargeted inhibitor against Cervical Cancer

Journal of Biomolecular Structure and Dynamics, 2022
The 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.

Metabolomic and transcriptomic analyses identify quinic acid protecting eggplant from damage caused by western flower thrips.

Pest Management Science, 2022
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.

Caffeoyl substitution decreased the binding and inhibitory activity of quinic acid against α-amylase: The reason why chlorogenic acid is a relatively weak enzyme inhibitor.

Food Chemistry, 2021
α-Amylase inhibition of chlorogenic acid (CHA) and its component moieties including quinic acid (QA) and caffeic acid (CA) were characterized by IC50, inhibition kinetics, fluorescence quenching, isothermal titration calorimetry, differential scanning ...
