第 11 族金属配合物表现出有前景的抗菌和抗癌特性，可以通过适当的配体进一步增强这些特性。在此，合成了一系列带有二膦 (P^P) 或 N-杂环卡宾 (NHC) 辅助配体 (L) 的单核硫代酰胺基 Cu(I) 和 Ag(I) 配合物，并合成了共-评估了配体L对其复合物的体外抗菌和抗癌特性的影响。所有复合物均能有效抑制各种细菌菌株的生长，其中 NHC-Cu(I) 复合物对革兰氏 () 细菌特别有效（IC50 = 1-4 μg mL-1）。针对各种人类癌细胞的细胞毒性研究揭示了它们的高抗癌效力和 NHC-Ag(I) 复合物的卓越活性 (IC50 = 0.95-4.5 μM)。对用 NHC-Ag(I) 复合物处理的肺癌和乳腺癌细胞进行的流式细胞术分析表明存在凋亡细胞死亡途径；分子对接计算提供了机制见解，证明了复合物结合凋亡调节蛋白并影响其功能的能力。版权所有 © 2023 Elsevier Inc. 保留所有权利。

Group 11 metal complexes exhibit promising antibacterial and anticancer properties which can be further enhanced by appropriate ligands. Herein, a series of mononuclear thioamidato Cu(I) and Ag(I) complexes bearing either a diphosphine (P^P) or a N-heterocyclic carbene (NHC) auxiliary ligand (L) was synthesized, and the impact of the co-ligand L on the in vitro antibacterial and anticancer properties of their complexes was assessed. All complexes effectively inhibited the growth of various bacterial strains, with the NHC-Cu(I) complex found to be particularly effective against the Gram (+) bacteria (IC50 = 1-4 μg mL-1). Cytotoxicity studies against various human cancer cells revealed their high anticancer potency and the superior activity of the NHC-Ag(I) complex (IC50 = 0.95-4.5 μΜ). Flow cytometric analysis on lung and breast cancer cells treated with the NHC-Ag(I) complex suggested an apoptotic cell-death pathway; molecular docking calculations provided mechanistic insights, proving the capacity of the complex to bind on apoptosis-regulating proteins and affect their functionalities.Copyright © 2023 Elsevier Inc.
