Composition of 1,3,4-selenadiazole containing compounds with pharmacological activity

Abstract

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.

[0185] The 1,3,4-selenadiazole containing compounds described above showed antioxidant activity and protect PC12 cells (1000 per well) under anaerobic condition or in the presence of hydrogen peroxide. As shown in FIG. 1, 1,3,4-selenadiazole compounds (10000 nM) could protect and support cell growth under anaerobic condition for 3 days, whereas in the no compound control, cells did not survive.

Example 2

[0186] Further studies have shown that the selenadiazole containing KGA allosteric inhibitors have strong KGA inhibition (IC50<100 nM) and anti-tumor activity (IC50<100 nM for inhibiting A 549 lung cancer cells). The molecular structure of specific compounds is described as follows:
