The invention belongs to the field of biomedical research involving the 1,3,4-selenyldiazo derivatives that have cell protective activity. Because there are not so many heterocyclic selenium compounds, we synthesized a new type of selenium analog of BPTES. As the isoacceptor of BPTES, the compounds have antitumor activity, anti-oxidation and cell protection function. Currently many drugs contain the thiodiazo motif, so synthesis of selenyldiazo functional group could further optimize these drugs and are important in new drug development and application.
