Most of the organic solvents tested were found to stimulate the mutagenicities of some mutagenic compounds. These stimulated compounds were restricted to the sugar-degradation products among various mutagenic compounds. From reduction of Nitro Blue tetrazolium (NBT), it can be said that all of the sugar-degradation compounds tested formed oxygen radicals in alkali conditions by autoxidation, and it was confirmed that the rates of the reducion of NBT by these compounds were greatly stimulated by various organic solvents. Further, the depolymerization of DNA by sugar-degradation compounds was found to stimulated by organic solvents. These results demonstrate that organic solvents enhance the oxygen radical formation of these sugar-degradation compounds, which leads to the stimulation of their mutagenicity.
