Eighteen Se-substituted selenocysteine derivatives were synthesized as potential kidney selective prodrugs which can be activated by renal cysteine conjugate beta-lyase to selenium-containing chemoprotectants or antitumor agents. Selenocysteine derivatives with aliphatic and benzylic Se-substituents were synthesized by reducing selenocystine to selenocysteine

The role of selenium as potential cancer chemopreventive and chemotherapeutic agents has been supported by epidemiological, preclinical and clinical studies. Although cell apoptosis has been evidenced as a critical mechanism mediating the anticancer activity of selenium, the underlying molecular mechanisms
