研究薯蓣皂苷元衍生物在体外的抗肿瘤活性。方法

采用MTT 法对人恶性黑色素瘤细胞A375、人肺腺癌细胞

A549、人肝癌细胞HepG -2及人慢性髓原白血病细胞株K562进行体外抗肿瘤活性试验。结果薯蓣皂苷元衍生物对4个肿

瘤细胞株A375、

A549、K562、HepG -2具有不同程度的抗肿瘤活性。结论绝大部分薯蓣皂苷元衍生物对4个肿瘤细胞株有

较好的抗肿瘤活性,

IC 50值都低于30μmol ·L -1

。化合物22对细胞株A375的IC 50=4.48μmol ·L -1,化合物9、

10对细胞株K562的IC 50分别为2.51、2.38μmol ·L -1;显示其抗肿瘤活性与对照化合物1-(3β-薯蓣皂苷元)-3-苄基咪唑溴盐相当。关键词:薯蓣皂苷元衍生物;抗肿瘤活性;K562;A375中图分类号:R96

To investigate the anti -tumor activity of diosgenin derivatives in vitro.METHODS

The anti -tumor activities of diosgenin derivatives were studied using human malignant melanoma A375cells ,human lung adenocarcinoma A549cells ,human hepatoma HepG -2cells and Human myeloid leukemia K562cells in vitro by MTT assay.RESULTS Their anti -tumor

activities against cell lines A375,A549,K562,and HepG -2were tested.Most of the diosgenin derivatives exhibited good anti -tumor

activities against all the four cancer cell lines.CONCLUSION

Most of the diosgenin derivatives exhibited good anti -tumor activi-ties against all the four cancer cell lines ,and all IC 50values were below 30μmol ·L -1.Among these compounds ,IC 50value of com-pound 22against A375was 4.48μmol ·L -1,and IC 50values of compound 9,10against K562were 2.51μmol ·L -1and 2.38μmol ·L -1.These showed they had the same anti -tumor activity as 1-(3β-diosgenin )-3-benzylimidazole bromo salt which was used as positive control.

薯蓣皂苷元属于甾体类化合物,为人红白细胞

白血病巨核细胞分化的诱导剂,对人骨肉瘤1547也有明显的抑制作用,还能诱导MCF 、

L929,、A375-S2、Hela 肿瘤细胞株发生细胞凋亡,对MGC -803、HeLa 、A375-S2、MCE -7等10种人肿瘤细胞株有

抑制其增殖的作用,且具有一定的选择性[1-4]

。研究结果表明:薯蓣皂苷元及其衍生物可作为潜在的

抗肿瘤活性物质进行研究。为此,特通过对人恶性

黑色素瘤细胞A375、人肺腺癌细胞A549、人肝癌细胞HepG -2及人慢性髓原白血病细胞K562进行体外抗肿瘤活性试验,研究本实验室合成的1 37号薯蓣皂苷元衍生物(图1)的抗肿瘤活性,期待有助于寻找到抗肿瘤活性更佳的衍生物。
