Abstract
Binding of microtubule filaments by the conserved Ndc80 protein is required for kinetochore-microtubule attachments in cells and the successful distribution of the genetic material during cell division. The reversible inhibition of microtubule binding is an important aspect of the physiological error correction process. Small molecule inhibitors of protein-protein interactions involving Ndc80 are therefore highly desirable, both for mechanistic studies of chromosome segregation and also for their potential therapeutic value. Here, we report on a novel strategy to develop rationally designed inhibitors of the Ndc80 Calponin-homology domain using Supramolecular Chemistry. With a multiple-click approach, lysine-specific molecular tweezers were assembled to form covalently fused dimers to pentamers with a different overall size and preorganization/stiffness. We identified two dimers and a trimer as efficient Ndc80 CH-domain binders and have shown that they disrupt the interaction between Ndc80 and microtubules at low micromolar concentrations without affecting microtubule dynamics. NMR spectroscopy allowed us to identify the biologically important lysine residues 160 and 204 as preferred tweezer interaction sites. Enhanced sampling molecular dynamics simulations provided a rationale for the binding mode of multivalent tweezers and the role of pre-organization and secondary interactions in targeting multiple lysine residues across a protein surface.

Abstract
Among the various challenges in medicine, diagnosis, complete cure and healing of cancers remain difficult given the heterogeneity and complexity of such disease. Differing from conventional platforms with often unsatisfactory theranostic capabilities, the contribution of supramolecular interactions, such as hydrogen-bonds (H-bonds), to cancer nanotheranostics opens new perspectives for the design of biomedical materials, exhibiting remarkable properties and easier processability. Thanks to their dynamic characteristics, a feature generally observed for non-covalent interactions, H-bonding (macro)molecules can be used as supramolecular motifs for yielding drug- and diagnostic carriers that possess attractive features, arising from the combination of assembled nanoplatforms and the responsiveness of H-bonds. Thus H-bonded nanomedicine provides a rich toolbox that is useful to fulfill biomedical needs with unique advantages in early-stage diagnosis and therapy, demonstrating the promising potential in clinical translations and applications. We here summarize the design and synthetic routes towards H-bonded nanomedicines, focus on the growing understanding of the structure-function relationship for efficient cancer treatment. We propose a guidance for designing new H-bonded intelligent theranostic agents, to inspire more successful explorations of cancer nanotheranostics and finally to promote potential clinical translations.

Abstract
A series of model compounds containing 3-amino-1H-pyrazole-5-carboxylic acid residue with N-terminal amide/urethane and C-terminal amide/hydrazide/ester groups were investigated by using NMR, Fourier transform infrared, and single-crystal X-ray diffraction methods, additionally supported by theoretical calculations. The studies demonstrate that the most preferred is the extended conformation with torsion angles ϕ and ψ close to ±180°. The studied 1H-pyrazole with N-terminal amide/urethane and C-terminal amide/hydrazide groups solely adopts this energetically favored conformation confirming rigidity of that structural motif. However, when the C-terminal ester group is present, the second conformation with torsion angles ϕ and ψ close to ±180° and 0°, respectively, is accessible. The conformational equilibrium is observed in NMR and Fourier transform infrared studies in solution in polar environment as well as in the crystal structures of other related compounds. The observed conformational preferences are clearly related to the presence of intramolecular interactions formed within the studied residue.

Abstract
Cyclization into closed assemblies is the most recurrent approach to realize the noncovalent synthesis of discrete, well-defined nanostructures. This review article particularly focuses on the noncovalent synthesis of monocyclic hydrogen-bonded systems that are self-assembled from a single molecule with two binding-sites. Taking advantage of intramolecular binding events, which are favored with respect to intermolecular binding in solution, can afford quantitative amounts of a given supramolecular species under thermodynamic control. The size of the assembly depends on geometric issues such as the monomer structure and the directionality of the binding interaction, whereas the fidelity achieved relies largely on structural preorganization, low degrees of conformational flexibility, and templating effects. Here, we discuss several examples described in the literature in which cycles of different sizes, from dimers to hexamers, are studied by diverse solution or surface characterization techniques.

Abstract
We prepared 1H-imidazolecarboxamide amphiphiles as potential organogelators. Compounds A1-A3, in which an imidazole head was connected to a hydrophobic trialkyloxyphenyl group, showed an ability to gelate nonpolar solvents, including alkanes. The dry gels obtained from compounds A1-A3 had columnar hexagonal structures. Polycatenar 1H-imidazolecarboxamide amphiphile B2, consisting of a 1H-imidazole head connected through a benzene ring to a tridecyloxyphenyl tail, formed an organogel in DMSO. In a concentrated THF solution (30 wt %), compound B2 exhibited a lyotropic liquid-crystalline phase with a columnar hexagonal structure. X-ray diffraction (XRD) results suggested a molecular arrangement consisting of a disk, via hydrogen bonding between successive imidazole moieties, and an assembly of columnar structures.

Abstract
We report the self-assembly of a hydrophilic 8-(m-acetylphenyl)-2'-deoxyguanosine (mAG) derivative into a discrete and thermally stable hexadecameric supramolecule in aqueous media. We demonstrate that this hexadecamer is isostructural to the one formed by a related lipophilic derivative in organic media. This mAG moiety represents a rare example of a small-molecule recognition motif that is capable of assembling isostructurally and with high fidelity in both organic and aqueous media.
