Cystine seleno

Sodium selenite and selenodiglutathione have been found to be more effective in inhibiting the growth of Ehrlich ascites tumors than sodium selenide, dimethyl selenide or seleno-DL-cystine. Preincubation of tumor cells with either 1 or 3 ppm Se as GSSeSG, Na SeO or dimethylselenide before reinoculated into mice resulted in a significant increase in survival in mice inoculated with cells pretreated with GSSeSG (69) (Table IV).

Selenium substitutes for sulfur in amino acids to form seleno-cysteine, cystine, and methionine. The selenium-containing antioxidant glutathione peroxidase is biologically important, and selenium is a necessary trace nutrient in warm-blooded animals. Grazing animals develop a form of muscular dystrophy and other disorders when grazing in areas in which the selenium has been depleted with selenium-depleted diets, people develop...
