Abstract

A novel selenadiazol derivative (BSBD) has been synthesized, characterized and evaluated for its anticancer activity. The in vitro anticancer activities of BSBD were screened by MTT assay against various cancer cell lines and it was found that BSBD could effectively inhibit cancer cell growth, especially for Nuero-2a neuroblastoma cells. Further investigation on the action mode showed that BSBD could induce Sub-G1 peak accumulation, chromatin condensation and the formation of apoptotic body in a dose-dependent manner in cancer cells, indicating that induction of apoptosis is the main mechanism accounting for the action of BSBD. Moreover the interaction between BSBD and bovine serum albumin (BSA) was investigated by UV-Vis, fluorescence and circular dichroism spectrometry and FTIR. The binding constants, number of binding sites and type of binding force were calculated by applying the equation of site-binding model and thermodynamic equations. The results of UV-Vis, FTIR and circular dichroism spectrometry revealed that the major interaction mode between BSA and BSBD was static quenching, due to hydrogen bonding and van der Waals force. The results of spectroscopic characterization showed BSBD altered the chemical structure and conformation of BSA.
