Selective Effects of Diallyl Disulfide, a Sulfane Sulfur Precursor, in the Liver and Ehrlich Ascites Tumor Cells

The present in vivo studies demonstrated that diallyl disulfide (DADS), occurring in garlic, elevated hepatic sulfane sulfur level and activities of gamma-cystathionase and 3-mercaptopyruvate sulfotransferase in healthy mice but did not affect the hepatic glutathione level. DADS efficiently corrected the concentrations of glutathione and sulfane sulfur, and ameliorated gamma-cystathionase activity that had been lowered in the livers of Ehrlich ascites tumor-bearing mice. In Ehrlich ascites tumor cells, diallyl disulfide did not alter bound sulfane sulfur level, sulfotransferases activity or glutathione level. These data indicate that this compound is capable of acting efficiently and selectively only in the liver and can be used for hepatoprotection during chemotherapy.
