Effect of Disulfiram Administration on Rat Brain Glutathione Metabolism

http://www.ncbi.nlm.nih.gov/pubmed/8142069

This study is not about brain tumors, but it does show that oral administration of disulfiram to rats (12 mg/kg), which would convert to about 125 mg for an average adult using allometric scaling, is sufficient to decrease the brain levels of reduced glutathione (GSH), increase the levels of oxidized glutathione (GSSG), and thereby decrease the ratio of reduced to oxidized glutathione from 122:1 to 12.8:1.

I propose that this could be a particularly effective therapy in IDH1-mutant tumors, which already have lowered baseline levels of NADPH, reduced glutathione (GSH) and impaired antioxidant capacity.

I will add this study to the Library.

A typical anti-alcohol abuse dose for disulfiram is 250 mg daily (500 mg has also been used).  Watch out for peripheral neuropathy (pain, tingling, numbness in fingers, toes, etc.).
