The Augmenting Activity of 6-(Methylsulfinyl)hexyl Isothiocyanate on Cellular Glutathione Levels Is Less Sensitive to Thiol Compounds Than Its Cytotoxic Activity

摘要

We analyzed the effects of thiol compounds on the biological activities of 6-(methylsulfmyl)hexyl isothiocyanate (6-MITC). Thiol compounds abolished the cytotoxic activity of 6-MITC, but did not abolish its activity augmenting cellular total glutathione levels and gamma-glutamylcysteine ligase gene expression. Thiol compounds might play an important role in the augmentation of several significant biological activities by overcoming the inherent limitations of 6-MITC.
