Similar to what we previously reported in cancer cells growing under normal oxygen conditions, our data shows that 2-DG interferes with the process by which sugars are added onto proteins (n-linked glycosylation) that are critical for the functioning of tumor cells as well as viruses. These results further indicate the wide-reaching and extraordinary role that 2-DG is just now beginning to gain recognition for, as both an anti-cancer as well as an anti-viral agent. Although much work remains to be done to bring 2-DG to clinical application in both of these global diseases, our findings in Phase I trials where 2-DG was found to be well-tolerated by cancer patients treated over extended periods offer much hope that these goals can realistically be achieved.
