摘要
目的:探讨5种白芷香豆素类化合物欧前胡素、异欧前胡素、氧化前胡素、白当归脑、异补骨脂素对MCF-7、MDA-MB-231细胞的化疗增敏作用。方法:体外培养MCF-7、MDA-MB-231乳腺癌细胞,分别给予不同浓度的白芷香豆素类化合物欧前胡素、异欧前胡素、氧化前胡素、白当归脑以及异补骨脂素作用72 h,采用MTT法评价其对MCF-7和MDA-MB-231细胞增殖的影响。以最大无毒浓度的欧前胡素、异欧前胡素、氧化前胡素、白当归脑以及异补骨脂素联合不同浓度的阿霉素作用72 h,采用MTT法评价上述5种白芷香豆素类化合物与化疗药物阿霉素合用后对MCF-7和MDA-MB-231细胞增殖的影响。结果:5种白芷香豆素类化合物对MCF-7细胞的增殖有抑制作用,其中以欧前胡素和白当归脑作用最为明显,二者作用于MCF-7细胞72 h的IC_(50)值分别为68.24μg/mL和54.20μg/mL;欧前胡素、异欧前胡素、氧化前胡素和异补骨脂素对MDA-MB-231细胞增殖有抑制作用,以异欧前胡素和欧前胡素作用最明显,二者作用于MDA-MB-231细胞72 h的IC_(50)值分别为44.64μg/mL和71.11μg/mL,而白当归脑作用较弱。与不同浓度的阿霉素单独组比较,不同浓度的阿霉素与欧前胡素、氧化前胡素和白当归脑合用后对MCF-7和MDA-MB-231细胞的增殖抑制作用更为明显,IC_(50)明显降低,增敏倍数增加。结论:白芷香豆素类化合物欧前胡素、氧化前胡素和白当归脑对MCF-7和MDA-MB-231乳腺癌细胞具有化疗增敏作用。
        AIM: To investigate the effects of coumarins from Angelica dahurica(imperatorin, isoimperatorin, oxypeucedanin, byakangelicol, isopsoralen) on chemotherapeutic sensitivity of two different breast cancer cell lines, MCF-7 and MDA-MB-231. METHODS: MCF-7 and MDA-MB-231 cells were treated with different concentrations of imperatorin, isoimperatorin, oxypeucedanin, byakangelicol, and isopsoralen for 72 h, respectively. The cytotoxity was evaluated by MTT assay.MCF-7 and MDA-MB-231 cells were treated with different doses of adriamycin in combination with the maximum nontoxic concentrations of imperatorin, isoimperatorin, oxypeucedanin, byakangelicol, and isopsoralen for 72 h, respectively. The cytotoxity was evaluated by MTT assay. RESULTS:Five furanocoumarins, especially imperatorin, byakangelicolin caused an antiproliferative effect in MCF-7 cells. The IC_(50) values of imperatorin, byakangelicolin in MCF-7 cells at 72 h post-treatment were 68.24 μg/mL and 54.20 μg/mL, respectively. Imperatorin, isoimperatorin, oxypeucedanin and isopsoralen caused an antiproliferative effect in MDA-MB-231 cells. The IC_(50) values of isoimperatorin, imperatorin in MDA-MB-231 cells at 72 h post-treatment were 44.64 μg/mL and 71.11 μg/mL respectively. Byakangelicolin had weak or no effects on the proliferation. Compared with the adriamycin group, the inhibitory effect of adriamycin combined with imperatorin, isoimperatorin and byakangelicolin on the proliferation of MCF-7 and MDA-MB-231 cells was more obvious. The value of IC_(50) was decreased and the potentiation folds of adriamycin was increased.CONCLUSION: Imperatorin, oxypeucedanin and byakangelicol can inhibit proliferation of MCF-7 cells and MDA-MB-231 cells, and enhance the chemotherapeutic sensitivity.
