C60基Ebselen衍生物：合成及尤其对鼠胸腺细胞增强保护效应

丙二酸酯衍生物2用2-氯硒基苯甲酰氯和2-(2-胺基乙氧基)乙醇为原料，经三步合成制得。2与C₆₀的Bingel环加成反应制得C₆₀基Ebselen衍生物3，产率为42% (基于已反应的C₆₀)，¹HNMR、¹³CNMR、IR、FAB-MS和元素分析鉴定了其结构。为了证实3对鼠胸腺细胞的活力具有增强效应，C₆₀衍生物4和2被选择，并采用与3相同的方法来处理鼠胸腺细胞，结果显示：3处理组的MTT(OD)值(0.335 ± 0.021)高于4处理组(MTT(OD): 0.283 ± 0.031)和2处理组(MTT(OD):0.247 ± 0.025)，表明3在促进鼠胸腺细胞活力方面优于2 和 4。

C60‐Based Ebselen Derivative: Synthesis and Enhanced Protective Effect on Mouse Thymus Cells

A C₆₀‐based ebselen derivative 3 was synthesized through a Bingel cyclopropanation of C₆₀ with the ebselen malonate 2 . It was obtained in a three‐step synthesis starting from 2‐(chloroseleno)benzoyl chloride and 2‐(2‐aminoethoxy)ethanol, in a 42% yield (based on consumed C₆₀). Its structure was characterized by ¹H NMR, ¹³C NMR, IR, FAB‐MS, and elemental analyses techniques. To verify that the C₆₀‐based ebselen derivative 3 had enhanced effect on viability of mouse thymus cells, the C₆₀ derivative 4 and ebselen derivative 2 were selected to treat the mouse thymus cells using the same procedures as those with the C₆₀‐based ebselen derivative 3 . The result shows that MTT(OD) values of compound 3 treated groups (0.335±0.021) were all higher than those of compound 4 (0.283±0.031) and compound 2 (0.247±0.025) treated groups, indicating that the compound 3 has an advantage over compounds 2 and 4 in promoting the viability of the mouse thymus cell.
