The present invention provides a heat-generating agent or singlet oxygen-generating agent effective as a new cancer treatment agent which, unlike an anticancer agent based on an alkylating agent such as MMC, uses the action of heat and/or singlet oxygen to kill cancer cells and reduce the burden on patients. A heat- and/or singlet oxygen-generating agent or a cancer treatment agent, comprising an organic peroxide such as the peroxide of an imidazole derivative or a chemiluminescent compound such as a dioxetane compound.

The thermal reaction of chiral 2-phenyl-4-(p-X-phenyl)-5-(p-Y-phenyl)-4-tert-butyldimethylsilylperoxy-4H-isoimidazoles (5b: X = CF3, Y = OMe; 5c: X = CF3, Y = F) was carried out in DMSO. The chiral 2-phenyl-5-(p-X-phenyl)-5-(p-Y-phenyl)-5H-imidazol-4-ones (4b: X = CF3, Y = OMe; 4c: X = CF3, Y = F) were quantitatively obtained in 50–60% enantiomer excess (ee). The mechanism for the reaction was proved
A linear correlation existed between the absorption energy of activators (E o-o 's) and the sensitized chemiluminescence (CL) yields (Φ SCL 's) for the CL reaction of lophine peroxides (2a and 2b), whereas a linear correlation did not exist between their oxidation potentials (E ox 's) and Φ SCL 's. Based on the finding, an energy transfer mechanism is likely rather than an electron transfer mechanism
