<p>Applications Gallic Acid-d2 is the labelled analogue of Gallic acid (G188978) which is a phenolic acid with antioxidant activity. Gallic acid was found to protect human cells against oxidative damage and showed cytotoxicity against cancer cells. Gallic Acid and its esters also show antiviral and antifungal activities.<br>References Yen, G. et al.: Food Chem., 79, 307 (2002); Chen, C. et al.: Mol. Nutrit. Food Res., 51, 962 (2007); Kratz, J. et al.: Mem. Inst. Oswaldo Cruz, 103, 437 (2008); Osborne, L. et al.: Infect. Immun., 33, 769 (1981);<br></p>

<p>Applications Gallic Acid exhibits a number of cellular effects including apoptosis and inhibits the growth of calf pulmonary arterial endothelial cell (CPAEC);Also, it is a polyphenol widely found in numerous fruits and vegetables that has been reported to exert anticancer effects, including apoptosis, against cancer cell lines.<br>References Park, W. H.: Mol. Med. Rep., 16, 7805-7812 (2017); Yang, C., et al.: RSC Adv., 8, 12449-12458 (2018)<br></p>
