Borodin, Oleg;Shchukin, Yevhenii;Robertson, Craig C.;Richter, Stefan;von Delius, Max research published 《 Self-Assembly of Stimuli-Responsive [2]Rotaxanes by Amidinium Exchange》, the research content is summarized as follows. Advances in supramol. chem. are often underpinned by the development of fundamental building blocks and methods enabling their interconversion. In this work, we report the use of an underexplored dynamic covalent reaction for the synthesis of stimuli-responsive [2]rotaxanes. The formamidinium moiety lies at the heart of these mech. interlocked architectures, because it enables both dynamic covalent exchange and the binding of simple crown ethers. We demonstrated that the rotaxane self-assembly follows a unique reaction pathway and that the complex interplay between crown ether and thread can be controlled in a transient fashion by addition of base and fuel acid. Dynamic combinatorial libraries, when exposed to diverse nucleophiles, revealed a profound stabilizing effect of the mech. bond as well as intriguing reactivity differences between seemingly similar [2]rotaxanes.

Brager, Dominique M.;Marwitz, Alexander C.;Cahill, Christopher L. research published 《 A spectroscopic, structural, and computational study of Ag-oxo interactions in Ag⁺/UO₂²⁺ complexes》, the research content is summarized as follows. Twelve novel Ag⁺/UO₂²⁺ heterometallic complexes have been prepared and characterized via structural, spectroscopic, and computational methods to probe the effects of Ag-oxo interactions on bonding and photophys. properties of the uranyl cation. Structural characterization reveals Ag-oxo interaction distances ranging from 2.475(3) Å to 4.287(4) Å. These interactions were probed using luminescence and Raman spectroscopy which displayed little effect on the luminescence intensity and the energy of the Raman active U=O sym. stretch peak as compared to previously reported Pb-oxo interactions. Computational efforts via d. functional theory-based natural bond orbital anal. revealed that the highest stabilization energy associated with the Ag-oxo interaction had a value of only 11.03 kcal mol^-1 and that all other energy values fell at 7.05 kcal mol^-1 or below indicating weaker interactions relative to those previously reported for Pb²⁺/UO₂²⁺ heterometallic compounds In contrast, quantum theory of atoms in mols. anal. of bond critical point electron d. values indicated higher electron d. in Ag-oxo interactions as compared to Pb-oxo interactions which suggests more covalent character with the Ag⁺. Overall, this data indicates that Ag⁺ has a less significant effect on UO₂²⁺ bonding and photophys. properties as compared to other Pb²⁺, likely due to the high polarizability of the cation.

Brennecke, Benjamin;Wang, Qinghua;Haap, Wolfgang;Grether, Uwe;Hu, Hai-Yu;Nazare, Marc research published 《 DOTAM-Based, Targeted, Activatable Fluorescent Probes for the Highly Sensitive and Selective Detection of Cancer Cells》, the research content is summarized as follows. The utilization of an activatable, substrate-based probe design in combination with a cellular targeting approach has been rarely explored for cancer imaging on a small-mol. basis, although such probes could benefit from advantages of both concepts. Cysteine proteases like cathepsin S are known to be involved in fundamental processes associated with tumor development and progression and thus are valuable cancer markers. We report the development of a combined dual functional DOTAM-based, RGD-targeted internally quenched fluorescent probe that is activated by cathepsin S. The probe exhibits excellent in vitro activation kinetics which can be fully translated to human cancer cell lines. We demonstrate that the targeted, activatable probe is superior to its nontargeted analog, exhibiting improved uptake into α_νβ₃-integrin expressing human sarcoma cells (HT1080) and significantly higher resultant fluorescence staining. However, profound activation was also found in cancer cells with a lower integrin expression level, whereas in healthy cells almost no probe activation could be observed, highlighting the high selectivity of our probe toward cancer cells. These auspicious results show the outstanding potential of the dual functionality concept combining a substrate-based probe design with a targeting approach, which could form the basis for highly sensitive and selective in vivo imaging probes.
