The solubility of lithium diethyldithiocarbamate, lithium dipropyldithiocarbamate, lithium dibutyldithiocarbamate, and lithium bis(trifluoroethyl)dithiocarbamate was measured in liquid and supercritical carbon dioxide at (298, 308, and 318) K and at pressures between (80 and 250) bar. The solubilites were measured experimentally through traditional cloud point observations using a variable-volume stirred

The present invention provides a novel class of dithiocarbamate-metal complexes and their uses in medicine. Also provided by the invention are combinations and pharmaceutical compositions, comprising a dithiocarbamate (or thiuram disulphide) such as disulfiram and cyclodextrin, with a source of a heavy metal. Surprisingly, the inventors found a synergistic potentiation of the anti-tumor effect, when a dithiocarbamate/heavy metal mixture was combined with a cyclodextrin. The compounds and combination of the invention are particularly useful in the treatment of tumor diseases, and other disorders. Provided are the compounds, combination, pharmaceutical compositions and kits, as well as methods for the preparation of the combinations of the invention.

The gold(I)-dithiocarbamate (dtc) complex [Au(N,N-diethyl)dtc]2 was identified as the active cytotoxicagent in the combination treatment of sodium aurothiomalate and disulfiram on a panel of cancer cell lines. In addition to demonstrating pronounced differential cytotoxicity to these cell lines, the gold complex showed no cross-resistance in therapy-surviving cancer cells. In the course of a medicinal
金(I)-二硫代氨基甲酸盐 (dtc) 复合物 [Au( N , N-二乙基)dtc] 2被确定为金硫苹果酸钠和双硫仑联合治疗一组癌细胞系的活性细胞毒剂。除了对这些细胞系表现出明显的差异细胞毒性外,金复合物在治疗后存活的癌细胞中没有表现出交叉耐药性。在针对此类难溶性金 (I)-dtc 配合物开展的药物化学研究过程中,合成了超过 35 种衍生物,并使用 X 射线晶体学检查了 dtc 部分的结构。一组羟基取代的配合物具有改善的溶解度,并且发现这些配合物与β-环糊精(CD)形成2:1的主客体包合配合物,表现出罕见的“尾对尾”排列CD锥体。羟基取代的金 (I)-dtc 复合物与过量的磺丁基醚-β-CD 的配制可防止线粒体活性氧的诱导,而线粒体活性氧是金属药物开发中的主要负担。
