Description
S-(N-Phenylbutylthiocarbamoyl)-glutathione (PBITC) is a conjugate of phenylbutylisothiocyanate and glutathione. Isothiocyanates are typically found in plants of the Brassicaceae family, including broccoli, cabbage, and radish. Isothiocyanates are best known for their antioxidative, anticancer chemotherapeutic, chemopreventive, anti-angiogenic, and antibiotic properties. In vitro, PBITC increases caspase 3 activity and cleavage of poly(ADP)-ribose polymerase (PARP), inducing caspase-mediated apoptosis. This compound decreases oxidation of carcinogen NNK and increases activity of NADPH:quinone oxidoreductase and glutathione-S-transferase in vitro and in vivo.
