Propargylic sulfones possessing a 2-nitroimidazole function: Novel hypoxic-cell radiosensitizers with intracellular non-protein thiol depletion ability

Propargylic sulfones (1a-c) containing a 2-nitroimidazole structure were synthesized, and their non-protein thiol (NPSH) depletion abilities were investigated. Propargylic sulfones 1a,c containing an electron withdrawing p-nitrophenyl group showed high reactivity toward capturing glutathione (GSH), a typical intracellular NPSH, in phosphate buffer. Among the three propargylic sulfones 1a-c, carboxylic acid derivative 1c showed the most potent radiosensitizing activity toward hypoxic EMT6/KU tumor cells. In view of these results and the partition coefficients between 1-octanol and water, we concluded that appropriate NPSH-depletion ability and lipophilicity are both important in achieving potent hypoxic-cell radiosensitization by propargylic sulfones possessing a 2-nitroimidazole function in biological systems.
