| 中文摘要: |
| 从孕烯醇酮出发,通过酯化反应在3-位羟基上引入不同结构酯链,再对20-位羰基进行结构修饰,合成了10个(20R)-孕甾-5-烯-20-(2-甲氧基苯甲酸酯)类化合物,并通过IR、NMR及HRMS方法进行了结构表征。合成的化合物用噻吩蓝比色法(MTT)体外测试了对人宫颈癌细胞(HeLa)、人肺癌细胞(A549)、人甲状腺癌细胞(TPC-1)、人鼻炎癌细胞(CNE-2)以及人正常肾上皮细胞(HEK-293T)的增殖生长抑制活性,结果显示化合物2d和3d对A549的抑制效果显著,其IC50达到了7.9 μM和10.3 μM,而对人正常肾上皮细胞 HEK-293T细胞无毒性。 |
| 英文摘要: |
| Using pregnenlone as a raw material, ten (20R)-pregn-5-ene-20-(2-methoxybenzoate) compounds were designed and synthesized by esterification on 3-hydroxyl group and structural modification on 20-carbonyl group. Their structures were determined by IR, NMR and HRMS. The antiproliferative activity of the target compounds were evaluated against HeLa (human cervical cancer), A549 (Human lung cancer), TPC-1(Human thyroid cancer), CNE-2 (nasopharyngeal carcinoma) and human HEK-293T (Normal Kidney Epithelial) by MTT method in vitro. The results showed that the compounds 2d and 3d displayed distinct antiproliferative activity against A549 with the values of IC50 7.9 and 10.3 μM, and were almost inactive to HEK-293T cells. |
