通过硫供体的反应,二硫化物配体(SC 6 H 4 CO 2 H-4)2作为一系列第8组过渡金属的简单但通用的连接基。这导致了一系列同双金属钌和烯基化合物,[{M(CH = CHR)(CO)(PPh 3)2(O 2 CC 6 H 4 S-4)} 2 ](M = Ru,Os; R = C 6 H 4 Me-4)。可以通过使用掺入py联吡啶单元(R =(bpy)ReCl(CO)3)的前体来添加其他基于金属的官能度。[{Ru(dppm)2(O 2 CC 6 H 4 S-4)} 2 ] 2+(dppm =二苯基膦甲烷)可以用硼氢化钠还原二硫键,得到硫醇络合物[Ru(O 2 CC 6 H 4 SH-4)(dppm )2 ] +。该络合物与[AuCl(PPh 3)]反应,得到双金属化合物[Ru(dppm)2(O 2 CC 6 H 4 S-4)Au(PPh 3)] +。但是,通过顺式反应可以提供一种改进的

Heterometallic compounds as anticancer agents demonstratingin vivopotential for the first time. Titanocene–gold derivatives: promising candidates for renal cancer.
Supramolecular mono‐ and dinuclear liquid‐crystalline gold(I) aggregates have been synthesized by means of hydrogen bond interactions of 2,4,6‐triarylamino‐1,3,5‐triazine with thiolate moities of gold metalloacids [Au(PR3)(SC6H4COOH)] or [μ‐(binap)Au(SC6H4COOH)}2], in 1:1 and 2:1 molar ratio, respectively. All of the supramolecularaggregates display a stable columnar hexagonal mesophase (Colh) at
超分子单核和双核液晶金(I)聚集体是通过2,4,6-三芳基氨基-1,3,5-三嗪与金金属酸的硫醇盐部分[Au(PR 3)]的氢键相互作用合成的。(SC 6 H 4 COOH)]或[μ-(binap)Au(SC 6 H 4 COOH)} 2 ],摩尔比分别为1:1和2:1。所有的超分子聚集体均显示出稳定的柱状六方中间相(Col h) 在室温下。柱内的超分子排列由一维堆积的三嗪单元组成,连接的金属硫代酸片段的核心充当第四分支。金属硫代酸的含膦部分在脂族连续体中突出。这些复合物没有显示亲金属相互作用,但是这种策略对于未来设计包含相互作用金属片段的室温液相色谱中间相似乎很有希望。

ligand. The ADC has n drug moieties bound to the Trastuzumab antibody such that the ADC has a drug-to-antibody ratio (DAR) between 2 and 4 and the drug moieties are bound to the Trastuzumab antibody through cysteine (S) or lystine (Lys) residues. The disclosed ADCs are particularly useful in treating breast cancer.

We describe the preparation of gold(i)-compounds that are amenable to efficientbioconjugation with monoclonal antibodiesvia activated ester or maleimide linkers. New Trastuzumab-gold conjugates were synthesized and fully characterized. These bioconjugates are significantly more cytotoxic (sub-micromolar range) to HER2-positive breast cancer cells than the gold complexes and Trastuzumab.
