3,4-Dimethoxyphenylacetic acid (CAS 93-40-3)

3,4-Dimethoxyphenylacetic acid is a naturally occurring chemical compound widely distributed in plants, fungi, and bacteria. It serves as a monohydroxybenzoic acid and plays a role in the integrity and strength of plant cell walls. Additionally, it is a significant component of the plant cuticle, participating in the regulation of stomatal closure. Due to its diverse biological activities, 3,4-Dimethoxyphenylacetic acid has captivated the scientific community′s interest. Its applications in both in vivo and in vitro research are extensive. In vivo, it acts as a marker for the regulation of stomatal closure, as well as influencing cell wall integrity and strength and participating in the regulation of cuticular wax deposition. In vitro, it serves as a marker for cell proliferation regulation, cell death regulation, and gene expression regulation. Although the exact mechanism of action remains partially understood, scientists believe that 3,4-Dimethoxyphenylacetic acid acts as an inhibitor of the enzyme polyphenol oxidase, responsible for polyphenol breakdown. Furthermore, it is thought to bind to cell surface receptors involved in controlling cell proliferation, cell death, and gene expression.
