Further support to the hypothesis that antimutagenic activities of α, β-unsaturated carbonyl compounds against UV-induced mutagenesis of E. coli may be due to an interaction with thiol groups were obtained by an experiment with the supplement of glatathione to the assay medium. Antimutagenic activity against MNNG induced mutation was also observed.
进一步的支持证据表明,α, β-不饱和羰基化合物对紫外线诱导的大肠杆菌突变的抗突变活性可能与巯基的相互作用有关,这一发现是通过在实验介质中添加
谷胱甘肽进行的实验获得的。对于MNNG诱导的突变也观察到了抗突变活性。
