A series of gold(I) pioneer complexes bearing N-heterocyclic carbenes and steroid derivatives (ethynylestradiol and ethisterone) with the generic formula [Au(R -imidazol-2-ylidene)(steroid)] (where R=CH or CH CH OCH ) were synthesized, and the X-ray structure of a rare of gold(I)-estradiol derivative is discussed. Toxicity studies reveal notable antibacterial activity of the gold-based compounds, which is significantly increased in vivo by the presence of the estradiol unit. Toxicity profiling was estimated in vitro versus Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria, and in vivo on Galleria mellonella larvae against E. coli.
合成了一系列通式为[Au(R -咪唑-2-亚基)(甾体)](其中R = CH或CH CH OCH )的含N-杂环卡宾和甾体衍生物(乙炔雌二醇和炔诺酮)的金(I)先导配合物,并讨论了一种罕见的金(I)-雌二醇衍生物的X射线结构。毒性研究表明,这些金基化合物具有显著的抗菌活性,在体内,由于雌二醇单元的存在,其抗菌活性显著增强。对革兰氏阳性菌(金黄色葡萄球菌)和革兰氏阴性菌(大肠杆菌)进行了体外毒性分析,并在体内对大蜡螟幼虫针对大肠杆菌进行了毒性分析。
