WebOct 11, 2024 · Oxidative stress describes an imbalance between the production and accumulation of by-products of oxygen metabolism called reactive oxygen species (ROS). ROS molecules are (free) radicals that contain oxygen and react with other molecules inside a cell or tissue. In balanced quantities, they are essential for our health. WebChlorogenic acid is a well known natural product with important bioactivities. It contains an ester bond formed between the COOH of caffeic acid and the 3-OH of quinic acid. We synthesized a chlorogenic acid analogue, 3α-caffeoylquinic acid amide, using caffeic and quinic acids as starting materials. The caffeoylquinc acid amide was found to be much …
