摘要:
研究Antimycin类天然产物对三阴性乳腺癌细胞MDA?MB?231特异性生长抑制和杀伤作用.三种结构类似的天然产物Antimycin?1,?2和?3对MDA?MB?231细胞生长都有很强的抑制作用,其IC50分别为1.34±0.07,160±20和180±50 nmol·L-1,Antimycin?1活性是Antimycin?2和Antimycin?3的一百多倍.10 nmol·L-1的Antimycin?1就可有效抑制MDA?MB?231细胞增殖,药物处理细胞24和48 h后的抑制率分别达到约80%和90%.显微镜下可以观察到,10和100 nmol·L?1的Antimycin?1都不同程度地杀伤MDA?MB?231细胞,1000 nmol·L-1的Antimycin?1甚至使细胞几乎消溶,只留下突起的核和胞质残骸.而同样浓度药物造成的乳腺正常细胞MCF?10A和结肠癌细胞HCT116形态的改变不明显.1和5 nmol·L-1的Antimycin?1对细胞集落抑制率分别达到52%和95%.20和50 nmol·L-1的Antimycin?1也明显改变MDA?MB?231细胞核形态,核呈畸形,皱缩严重,核膜破损.5,10和100 nmol·L-1的Antimycin?1处理MDA?MB?231细胞12,24和48 h引发细胞凋亡和坏死数量增加,并呈现时间和剂量依赖性.5,10和20 nmol·L-1的Antimycin?1处理MDA?MB?231细胞6,12和24 h后,没有观察到对细胞周期时相的明显影响.20 nmol·L-1的Antimycin?1处理MDA?MB?231细胞12,16,20和24 h后,引起胞内活性氧(reactive oxygen species,ROS)水平随处理时间延长呈逐渐下降趋势.以上结果证明,纳摩尔级的Antimycin?1能有效抑制和杀伤三阴性乳腺癌MDA?MB?231细胞.
