The cover picture shows the cellular uptake of [ReIL(CO)3]n+ (L = ligand; n = 1 or 0) complexes with carbohydrate-pendant ligands. The ligand library includes (i) glucose/galactose as a carbohydrate, (ii) bis(2-pyridylmethyl)amine (DPA)/bis(2-quinolylmethyl)amine (DQA)/N-(2-pyridylmethyl)glycine (NPG) as the metal-binding component, and (iii) an ethylene chain as a linker between the metal-binding site and the O/C-glycosides. Microscopic analysis by using the fluorescent Re complex reveals that the complex stays in the cytosol and cannot penetrate into the nucleus. Details are discussed in the article by Y. Mikata et al. on p. 217ff.
