Usage

General Description

(-)-ECG-4''-O-ME is a chemical compound that is an ester derivative of (-)-epicatechin gallate (ECG). ECG is a type of catechin found in certain plants and is known for its antioxidant properties. When ECG is methylated at the 4'' position, it forms (-)-ECG-4''-O-ME. (-)-ECG-4''-O-ME has been studied for its potential health benefits, including its ability to protect cells from oxidative stress and its anti-inflammatory properties. It has also been investigated for its potential role in preventing cardiovascular diseases and certain types of cancer. More research is needed to fully understand the potential uses and effects of (-)-ECG-4''-O-ME.

Methylation of tea catechins by rat liver homogenates.

Methylation of (-)-epigallocatechin (EGC), (-)-epicatechin gallate (ECg), and (-)-epigallocatechin gallate (EGCg) was carried out with a rat liver homogenate and S-adenosyl-L-methionine. A structural analysis of the reaction products by MS and NMR showed

Regioselective synthesis of methylated epigallocatechin gallate via nitrobenzenesulfonyl (Ns) protecting group

Regioselective synthesis of methylated epigallocatechin gallate from epigallocatechin was accomplished using a 2-nitrobenzenesulfonyl (Ns) group as a protecting group for phenols. This methodology provided several methylated catechins, which are naturally
