A series of N‐aryl‐ and N‐alkyl substituted imidazoles has been synthesised and complexed with Ag+ to obtain silver‐NHC complexes of the form [Ag(NHC)2]X. These silver‐NHC complexes were tested in vitro against the human cell lines HL‐60 and MOLM‐13, which both model acute myeloid leukaemia (AML). A substantial difference in cytotoxicity was revealed varying in the range 13–4 μM and 22–9 μM for HL‐60
合成了一系列的N-芳基和N-烷基取代的咪唑并与Ag +络合,以获得[Ag(NHC)2 ] X形式的银-NHC络合物。这些银-NHC复合物在体外针对人类细胞系HL-60和MOLM-13进行了测试,它们均模拟急性髓细胞白血病(AML)。HL-60和MOLM-13的细胞毒性差异显着,分别在13–4μM和22–9μM之间。此外,这项研究表明,当在咪唑支架上安装烷基时,其位置会实质上影响相应的NHC银配合物的细胞毒性。
