Home of Kyle J. Norton for The Better of Living & Living Health Sulfur represents approximately 1/4% of our total body weight and occurs principally in the body as a constituent of the cysteine and methionine. It plays an important role in protein synthesis and enzyme reaction functions and is found abundantly in broccoli, cauliflower, cabbage, kale, kohlrabi, etc.
Organosulfides
Organosulfur compounds presented in natural food are generally considered as beneficial for health because of their antioxidant and anticarcinogenic properties. This has led to their excessive and long-term consumption. However, there is also evidence that these compounds demonstrate toxicity and adverse health effects suggesting their potential dual biological roles. Thus, they can act as double-edged biological swords(a).
Allyl isothiocyanate (AITC)
Allyl isothiocyanate (AITC) is organosulfur compounds found abundantly in cruciferous vegetables and responsible for the pungent taste of mustard, horseradish, wasabi, etc.
Allyl isothiocyanate and bladder cancer
Bladder cancer is one of the common human cancers and also has a very high recurrence rate. According to the study by the Roswell Park Cancer Institute, a low oral dose of AITC (1 mg/kg) significantly inhibited the development and muscle invasion of the orthotopic bladder cancers but was ineffective against the subcutaneous xenografts of the same cancer cells in the same animals. This differential effect was explained by our finding that urinary levels of AITC equivalent were two to three orders of magnitude higher than that in the plasma and that its levels in the orthotopic cancer tissues were also three orders of magnitude higher than that in the subcutaneous cancer tissues. Moreover, we show that AITC is a multi-targeted agent against bladder cancer(6).
