COMPOSITION FOR INCREASING LEVEL OF REACTIVE OXYGEN SPECIES, ANTITUMOR AGENT AND NOVEL CURCUMIN DERIVATIVE

摘要

To provide a composition for increasing a level of a reactive oxygen species including a curcumin derivative.SOLUTION: The present invention provides a composition for increasing a level of a reactive oxygen species, containing at least one compound selected from the group consisting of formulae A and B or a salt thereof. R-Rare independently selected from a hydroxy group, a C1-5 alkoxy group, a C1-5 hydrocarbon group, a halogen atom, a carboxy group, a nitro group, an amino group, a sulfo group, a cyano group, a silyl group and an aryl group. R-Rare independently selected from a hydrogen atom, a hydroxy group, a C1-5 alkoxy group, a C1-5 hydrocarbon group, a halogen atom, a carboxy group, a nitro group, an amino group, a sulfo group, a cyano group, a silyl group and an aryl group.SELECTED DRAWING: Figure 4
