Abstract
Reductone (HOCH 2-CO-CHO), a keto-aldehyde formed, in alkaline pH, by thermal degradation of reducing sugars, blocks cellular respiration and macromolecular biosynthesis, inactivates far-UV (254 nm)-irradiated wild-type E. coli cells, and causes DNA strand breaks. So it may be supposed to be an inducer of SOS functions. Indeed, when Salmonella tester strains TA98, TA100 and TA102 were treated with reductone solutions, without metabolization, a mutagenic effect was detected for all of them. Besides, reductone induced lysogenic E. coli cells and cell filamentation, as measured by the Inductest and the SOS Chromotest. So reductone must be considered a genotoxic drug.
