A series of variously functionalized selenium-containing compounds were purposely synthesized and evaluated against a panel of cancer cell lines. Most of the compounds showed an interesting cytotoxicity profile with compound 5 showing a potent activity on MCF7 cells. The ethyl amino derivative 5 acts synergistically with cis-platin and inhibits the GST enzyme with a potency that well correlates with the cytotoxicity observed in MCF7 cells. A computational analysis suggests a possible binding mode on the GST enzyme. As the main outcome of the present study, the ethyl amino derivative 5 emerged as a valid lead compound for further, future developments.

A target synthesis of a library of symmetric aromatic diselenides was attempted with the aim of generating anticancer lead compounds. Out of thirteen screened molecules (1-13) against a panel of human cancer cell lines, compound 8 exhibited highest cell growth inhibition in Human leukemia HL-60 cells with IC50 value of 8 μM. Compound 8 had a good pro-apoptotic potential as evidenced from several apoptotic protocols like DNA cell cycle analysis and monitoring of apoptotic bodies formation using phase contrast and nuclear microscopy with Hoechst 33,258. Also, 8 significantly inhibits S phase of the cell cycle and eventually trigger apoptosis in HL-60 cells through mitochondrial dependent pathway substantiated by the loss of mitochondrial potential. A theoretical investigation of DNA binding ability of 8 showed that it selectively bind to minor groove of DNA, where it is stabilized by hydrogen bonding and hydrophobic interactions.
