摘要：
The present invention discloses an amino mercaptan compound, preparation method thereof and use thereof in radiation protection. The compound has the structure of formula I, wherein A1 is selected from -C(O)NR8-,-S(O)2-NR8-, -S(O)NR8 or -R7-NR8-； A2 is selected from carbonyl, sulfonyl, sulfinyl, substituted or unsubstituted C1-6 alkyl； R1, R2, R5, and R6 may be the same or different and are selected from: hydrogen, substituted or unsubstituted C1-C5 alkyl or heteroalkyl； n is an integer from 0 to 20,000； R3 and R4 are independently selected from hydrogen, X, substituted or unsubstituted C1-6 alkyl； X is selected from F, Cl, Br or I； R7 is selected from substituted or unsubstituted C1-C6 alkyl； and R8 is selected from hydrogen, substituted or unsubstituted C1-C6 alkyl. The compound has the effects of reducing the biological damage caused by ionizing radiation, extending the survival period and survival rate of the radiated animals, and significantly alleviating the side effects of radiotherapy, and has a low toxicity. The present invention opens up a new way for protection and treatment of ionizing radiation damage.
