cytotoxicities and DNA cross-linking abilities of several alkyl-substituted diaziridinylquinones have been investigated. The cytotoxicities were determined in DT-diaphorase-rich (H460 and HT29) and -deficient (H596 and BE) cell lines. It was shown that the cytotoxicities in these cell lines correlated with the relative rates of reduction by the purified human enzyme and with the cross-linking efficiencies.
Provided is a composition containing, as an alkane polyol, a C4-18 1,2-alkane polyol in which the degradation over time of the C4-18 1,2-alkane polyol, which has inferior chemical stability and degrades easily, is suppressed, the composition being suitable for use in a cosmetic, an inkjet ink, a fiber or a coating material such as a paint. A composition containing 1,2-alkane polyol that can be used in a cosmetic, an inkjet ink, a raw material for fibers or a coating material, the alkane polyol being a C4-18 1,2-alkane polyol, and the composition containing a radical scavenger.
