<p>3,3'-(3,6-Dihydropyrazine-2,5-diyl)dipropanoic acid (DPPA) is a potent metal chelator that can be used in the treatment of cancer. DPPA binds to metal ions and prevents their access to vital cellular components such as DNA and proteins. This agent has been shown to inhibit the growth of carcinoma cells in culture. It also has an effect on the synthesis of demyelination, which may account for its ability to prevent reactive oxygen species from damaging DNA. DPPA is a strong inhibitor of mitochondrial function and at high concentrations it damages mitochondria by releasing hydrogen peroxide into the cell cytoplasm. The release of hydrogen peroxide causes catalase to become active, leading to cell death.</p>
