Some disulfides have previously been shown to possess antifungal and/or antileukaemic activity. Importantly, this cytotoxicity can be selective. We have previously shown that a subset of these compounds does not block the proliferative potential of normal, non-transformed cells. Based on these results and proposed mechanisms of action, a new set of structurally modified organosulfur compounds, including α-substituted disulfides and a thiosulfonate ester, have been prepared and evaluated for their potential as antileukaemic agents. Compounds were screened for antiproliferative activity against a panel of human cells derived from acute lymphocytic and acute myelogenous leukaemia, as well as non-transformed cells. We have identified five new disulfides and a thiosulfonate that can trigger tumour cells to undergo cell death by an apoptotic mechanism in a sensitive and specific manner.
一些二硫化物先前已被证明具有抗真菌和/或抗白血病活性。重要的是,这种细胞毒性具有选择性。我们之前已经证明,这些化合物中的一个子集不会阻碍正常、非转化细胞的增殖潜力。根据这些结果和提出的作用机制,我们制备了一组新的结构修饰型有机硫化合物,包括α-取代二硫化物和硫代磺酸酯,并对其作为抗白血病药物的潜力进行了评估。我们对来自急性淋巴细胞白血病和急性髓性白血病以及非转化细胞的一系列人类细胞进行了化合物抗增殖活性筛选。我们发现了五种新的二硫化物和一种硫代磺酸盐,它们能以敏感而特异的方式引发肿瘤细胞通过凋亡机制死亡。
