Compositions and methods for decreasing the viability of cells, particularly aberrant non-healthy cells, and most particularly cancer cells, are disclosed. The primary agent that causes cell death is a toxic metal atom or ion. Embodiments of the invention provide compositions and methods to ensure that the toxic metal is directed to the desired cell or tissue. In one embodiment, the metal is bound to a sulfur-rich peptide or protein carrier containing a targeting moiety. Such metal-protein complex is targeted to the selected cells or tissues to enrich the cell or tissue site with the metal-containing peptide or protein molecules followed by administering a dithiocarbonyl which carries the metal from the protein inside the cells to induce cell death.
本发明揭示了降低细胞活性的组合物和方法,特别是对于异常的非健康细胞,尤其是癌细胞。导致细胞死亡的主要成分是有毒金属原子或离子。本发明实施例提供了组合物和方法,以确保有毒金属定向到所需的细胞或组织。在一种实施例中,金属结合到含有靶向基团的硫富集肽或蛋白质载体上。这种金属-蛋白质复合物被定向到所选的细胞或组织,以富集含有金属的肽或蛋白质分子的细胞或组织位点,然后给予一种二硫代氨基甲酸盐,从蛋白质内部携带金属进入细胞,诱导细胞死亡。
