      Thumbnail image of graphical abstract

      The cover picture shows at the top the first two recognized examples of C–C agostic interactions with a metal center. A stylized arrow demonstrates the progression from the recognition that C–C bonds could donate electron density to a metal center to the understanding that these interactions are present in intermediates of both the Ziegler–Natta and olefin metathesis catalytic cycles. The impact of these interactions is then highlighted by depicting some of the ubiquitous consumer products that are manufactured by use of these catalytic cycles. Details are presented in the Microreview by B. G. Harvey and R. D. Ernst on page -- ff (DOI: 10.1002/ejic.201600989).

      Thumbnail image of graphical abstract

      We have prepared large distinct heteronuclear lanthanide architectures from kinetically inert building blocks. By combining optical and magnetic resonance spectroscopy, we are able to conclude that conformational freedom allowing for intramolecular collision is more important than apparent proximity for efficient energy transfer.

      [RhIII(*Cp)(curcuminato)Cl] (*Cp = pentamethylcyclopentadienato) is readily taken up by the A549 lung-cancer cell line and enables the slow intracellular release of curcumin that causes cytotoxicity by apoptosis. This makes the complex an effective drug-delivery system for the poorly bioavailable curcumin drug.

      Unlike agostic C–H and H–H bond coordination with transition-metal centers, analogous coordination involving C–C bonds was discovered only recently. Already it has been found to play roles in olefin metathesis and polymerization. We summarize the early work in this area, focusing on the nature of these species and the recognition that such complexes were around but unrecognized for some time.

      Radiolabeled amino acids are important imaging agents for rapidly proliferating cells. Tyrosine has been coupled to a tripod ligand and labeled with 99mTc in a two-step or one-pot reaction. Accumulation in tumor xenografts was small, but fast uptake into the gallbladder and retention over an extended period suggest that this compound is suitable for gallbladder imaging and related dysfunctions.

      The isomeric effect on the interaction of CuII antineoplastic coordination compounds with cellular membranes as well as on their biological activity has been studied. The isomer CasIII-La presents a lower-energy cost for crossing the cell membrane, which is reflected in a lower half-life and a greater cytotoxicity towards human peripheral blood lymphocytes compared with its isomer CasIII-Ea.

      Two Au–dithiocarbamato complexes are promising anticancer agents. Spectrometric studies revealed different patterns of interaction with HSA and ctDNA as model biomolecules, likely due to differences in redox chemistry. One complex was tested against A549 lung carcinoma cells using an xCELLigence Real-Time Cell Analysis system; measures of impedance by non-invasive Au microelectrodes showed that the complex inhibits cell proliferation after only 4 h.

      Cycloruthenated compounds have been shown to be amazingly stable and exciting anticancer drug candidates featuring original modes of action. The role of the C–Ru bond that is intramolecularly stabilized by dative bonds is highlighted, because the cytotoxicity of these compounds is often up to two or three orders of magnitude higher than that of structurally related species lacking the C–Ru bond.

      Two vanadium(V) complexes, based on a common branched diaminobis(phenolato) ligand but differing in their labile ligands, are highly cytotoxic toward human colon and ovarian cells, including cells that are resistant to cisplatin. Their rapid loss of the labile group in water implies that, unlike the chelating ligand, the labile ligand type is insignificant.

      Cisplatin selectively binds to ZFPs containing C4 or C3H motifs. MDM2-zf (C4) and PARP-1-zf2 (C3H) show a higher reactivity to cisplatin than Sp1-zf2 (C2H2). The platination of ZFPs causes the zinc release and structural perturbation of the proteins. The different reactivity of the various ZFPs may be correlated with the targeting of cisplatin in cells.

      Photolabile ruthenium complexes can cage a biologically active ligand and release it when irradiated with visible light. We present a series of complexes for light-activated delivery of the anticancer agent 6-mercaptopurine. Several complexes are able to release 6-mercaptopurine on irradiation with visible light and exhibit photoselective DNA binding or toxicity towards MCF-7 breast cancer cells.

      An unsymmetrically carboxylated platinum(IV) analogue of oxaliplatin is coupled to generation two (G-2) and four (G-4) polyamidoamine (PAMAM) dendrimers. The platinum–dendrimer complexes showed load- and size-dependent potency with IC50 values down to the low-nanomolar range, in contrast to the rather moderate activity of the free platinum(IV) compound.

      Thirty Years of the Drug Candidate NAMI-A and the Myths in the Field of Ruthenium Anticancer Compounds: A Personal Perspective

      Almost 30 years after the discovery of NAMI-A, and after two clinical phase studies have been accomplished, the time seems to be appropriate for drawing up a balance sheet. The undemonstrated misconceptions (or myths) that, over the years, have thrived around NAMI-A and other ruthenium drug candidates are also critically addressed in detail.

      The biological activity of a RuII polypyridyl complex 1 and an IrIII organometallic complex 2 on four cell lines is presented. Although the cytotoxicity of 1 did not improve significantly upon light irradiation, 2 reached nanomolar IC50 values on all the cell lines tested when activated with 420 nm light in low doses.
