nontoxic to the normal cells. Based on the LD50 values and selectivity index (SI), compound 3h (S-p-methoxybenzyl (p-methoxyphenyl)methanesulfinothioate) was considered as most promising anticancer agent amongst the above three compounds. Further bio-chemical studies confirmed that compound 3h promotes ROS generation, changes in mitochondrial permeability transition and induced caspase mediated DNA
以高收率合成了大蒜中存在的一系列大蒜素的新类似物(S-烯丙基丙-2-烯-1-磺基硫代乙酸盐)。针对不同的乳腺癌细胞(MDA-MB-468和MCF-7)和非癌细胞(WI38)评估了合成的23种化合物。四种化合物(3f,3h,3m和3u)对癌细胞具有明显的细胞毒性,而对正常细胞无毒性。基于LD 50值和选择性指数(SI),化合物3h(Sp-甲氧基苄基(对甲氧基苯基)甲亚磺酸硫酯)被认为是上述三种化合物中最有希望的抗癌剂。进一步的生化研究证实,化合物3h促进ROS的产生,线粒体通透性转变的变化并诱导caspase介导的DNA损伤和凋亡。
