Supramolecular compounds assembled by dinuclear zinc II) species containing Robson-type macrocycles and diverse organic subunits (4,4′-bipyridine, 2,2′-bipyridine, pyrazine, 4-aminopyridine, 4-pyridinecarboxylate, pyridine, and quinoline) are reviewed.
We show that compounds assembled on-site that recognize structure have the highest potencies amongst small molecules and are similar in potency to a vivo-morpholino modified oligonucleotide that targets sequence.
The F-box protein FBXL3 recognizes CRY2 by occupying the FAD binding pocket of CRY2 with its C-terminal tail and also covers the PER binding domain of CRY2. 5 To develop novel small-molecule modifiers of the circadian clock, we previously screened a collection of 60 000 structurally diverse compounds assembled from an in-house compound library using a cell-based Bmal1-dLuc reporter assay.
Some CH⋯N and CH⋯X (X = Cl, Br) hydrogen bonds have been found in the two compounds, which assemble the cations and anions into a three-dimensional network.
Layered double hydroxides (LDHs) are ordered compounds that assemble by interlamination anions and positively charged layer laminates with the general formula of [M1 − x2+M x 3+(OH)2]x+(An−)x/n·mH2O, where M2+ and M3+ represent metal cations and A is an anion [17].
The title compounds are assembled from six sugar amino acid dipeptide isosteres and are synthesized using solution-phase peptide synthesis protocols.
The X-ray crystal structures show that these compounds self-assemble in the lattice through a network of hydrogen-bonds between the amide groups, which overall results in infinite nanotubes formed by the calixarene aromatic cavities.
In addition to these compounds, the assembled library also contained methylglyoxal, a compound not readily detectable by our mass spectrometry method.
These compounds were assembled with a modular build/couple/pair synthetic strategy using different olefin-containing carboxylic acid and amino alcohol building blocks.
