pentameric, polymeric rings. The 197Au Mössbauer spectra are consistent with linear co-ordination of the gold by two sulphur ligands and, in agreement with the n.m.r. data, show broadening indicative of the presence of non-equivalent gold atoms. The therapeutic compounds appear to be structurally similar to the other gold(I) thiolates.
已经制备了许多硫醇金(I)[Au(SR)],其中R基团是烷基,芳基,羧酸,氨基酸或杂环。大多数在所有常用的溶剂高度不溶,但[AU(SC 6 H ^ 4 R'- p)](R'=乙基,丙基我,卜小号,或卜吨)在有机溶剂中溶解。可溶性化合物的1 H和13 C nmr光谱显示了几组信号,这些信号在高温下会聚结为一组信号,这与流动的,可能是五聚体的聚合物环的存在相一致。在197AuMössbauer光谱与两个硫配体对金的线性配位相一致,并且与nmr数据一致,显示出加宽的迹象表明存在不等价的金原子。治疗化合物似乎在结构上类似于其他硫醇金(I)。
Design, synthesis and characterisation of new chimeric ruthenium(<scp>ii</scp>)–gold(<scp>i</scp>) complexes as improved cytotoxic agents
for disruption of the bimetallic motif and for protein binding of monometallic fragments. Overall, the data reported here strongly support the concept of multifunctional heterometallic compounds as “improved” candidate agents for cancer treatment. The mechanistic and pharmacological implications of the present findings are discussed.
