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.
本发明公开了一种氨基硫醇化合物、其制备方法及其在辐射防护中的用途。该化合物具有式 I 的结构,其中 A1 选自 -C(O)NR8-、-S(O)2-NR8-、-S(O)NR8 或 -R7-NR8-;A2 选自羰基、磺酰基、亚磺酰基、取代或未取代的 C1-6 烷基;R1、R2、R5 和 R6 可以相同或不同,并且选自:氢、取代或未取代的 C1-C5 烷基或杂烷基;n 是 0 至 20,000 的整数;R3 和 R4 独立地选自氢、X、取代或未取代的 C1-6 烷基;X 选自 F、Cl、Br 或 I;R7 选自取代或未取代的 C1-C6 烷基;R8 选自氢、取代或未取代的 C1-C6 烷基。该化合物具有减轻电离辐射造成的生物损伤、延长受辐射动物的存活期和存活率、显著减轻放疗副作用等作用,且毒性低。本发明为电离辐射损伤的防护和治疗开辟了一条新途径。
