摘 要:为了克服依布硒林亲水性差及气味太重的缺点,同时保留依布硒林抗氧化的特性,参照现有方法放大合成了羧基依布硒林(ebselen)衍生物2-(4’-羧基苯基)-1,2-苯并异硒唑-3(2H)-酮,并对该方法优化、改进,用质谱及红外光谱对目标产物进行了表征。通过对合成的产物进行急性经口毒性试验,发现其经口半数致死量(LD50,medium lethal dose)大于5.5g/Kg,按照急性毒性分级标准确定该依布硒林衍生物属实际无毒级。 |

Abstract:In order to overcome its poor water-solubility and bad smell,while keep the unique antioxidation,the carboxyl derivative of ebselen,2-(4'-carboxyphenyl)-1,2-benzisoselenazol-3(2H)-ones,has been amplified synthesized based on known methods with some improvements,and characterized by MS and IR.The oral acute toxicity test showed LD50(medium lethal dose)>5.5 g/Kg.Such result demonstrates that the synthesized product is nontoxic according to the classification of acute toxicity standard. |
Key words:2-(4'-carboxyphenyl)-1; 2-benzisoselenazol-3(2H)-ones; carboxyl derivative of ebselen; antioxidation; cosmetic |
