The N-acetyl-S-allyl-L-cysteine (NAc-SAC) was synthesized by substitution and acylation reactions with L-cysteine as raw materials. Experiments on blood and immune-organs indexes, and survival rates of ICR mice within 30 d after 137Csγ-rays irradiation at different doses, as well as the comet assay were carried out to investigate the anti-irradiation effects of NAc-SAC. The survival rates of mice irradiated at 7.5 Gy with the dose of NAc-SAC at 200 mg/kg, 400 mg/kg, and 600 mg/kg increased to 58.3%, 50.0% and 66.7%, respectively, and the average survival time was significantly prolonged compared with that in the control group. The spleen indexes, colony forming cell-spleen (CFU-S), percentages of DNA, number of white blood cells of mice irradiated at 6.0 Gy increased under the action of NAc-SAC. The tail length, tail moment, olive tail moment, and tail DNA percentage of peripheral blood lymphocytes of mice irradiated at 7.0 Gy combined with NAc-SAC were higher than those for the control group (p<0.05). To conclude, NAc-SAC has a protective effect against damage induced by irradiation.
