Supramolecular Chirality in Metal–Organic Complexes

Accounts of Chemical Research, 2020
Chirality is a pervasive structural feature of nature and crucial to the organization and function of nearly all biological systems. At the molecular level, the biased availability of enantiomers in nucleic and amino acids forms the basis for asymmetry.

Supramolecular platinum complexes for cancer therapy

Current Opinion in Chemical Biology, 2023
The rise of supramolecular chemistry offers new tools to design therapeutics and delivery platforms for biomedical applications. This review aims to highlight the recent developments that harness host-guest interactions and self-assembly to design novel supramolecular Pt complexes as anticancer agents and drug delivery systems.

The chirality of dendrimer-based supramolecular complexes

Organic & Biomolecular Chemistry, 2005
Boc-protected L-phenylalanine has been connected to a spacer-armed ureido-acetic acid derivative, which can form multiple supramolecular complexes with urea-adamantyl modified poly(propylene imine) dendrimers in chloroform. Complexes of this guest with several generations of urea-adamantyl dendrimers were prepared.

PDZ Domains and the Organization of Supramolecular Complexes

Annual Review of Neuroscience, 2001
▪ Abstract  PDZ domains are modular protein interaction domains that bind in a sequence-specific fashion to short C-terminal peptides or internal peptides that fold in a β-finger. The diversity of PDZ binding specificities can be explained by variable amino acids lining the peptide-binding groove of the PDZ domain.

Selectivity in supramolecular host–guest complexes

Chem. Soc. Rev., 2008
The background of possible selectivity-affinity correlations and their limitations is reviewed, with typical crown ether and cryptand complexes, ionic associations, hydrogen bonded complexes and complexes driven by van der Waals, stacking or hydrophobic interactions, with some additional topics including associations based on metal coordination as ...

Supramolecular Complexes of DNA

2009
Deoxyribose nucleic acid or DNA is a linear polymer in the form of a double strand, synthesised by sequential polymerisation of a large number of units chosen from among the nucleic bases called purines (adenosine A and guanosine G) and pyrimidines (cytosine C and thymidine T). DNA contains all the genetic information required for life.

Supramolecular Signalling Complexes in the Nervous System

2007
It is now apparent that multiprotein signalling complexes or "signalling machines" are responsible for orchestrating many complex signalling pathways in the cell. The synapse is a sub-cellular specialisation which transmits and converts patterns of electrical activity into cellular memory.

Supramolecular Adsorption of Alkaloids by Metallosalphen Complexes

Inorganic Chemistry, 2008
Mono and bis-zinc(II)-centered salphen derivatives 1-5 are presented as efficient adsorption materials for pyridine-based alkaloid derivatives. The different alkaloid assemblies were studied by UV-vis and NMR spectroscopy, and high binding constants (Ks approximately 10(5)) were additionally determined for the supramolecular complexes based on nicotine.

Transmetalation of self-assembled, supramolecular complexes

Chem. Soc. Rev., 2014
Substituting one metal for another in inorganic and organometallic systems is a proven strategy for synthesizing complex molecules, and in some cases, provides the only route to a particular system. The multivalent nature of the coordination in metal-ligand assemblies lends itself more readily to some types of transmetalation.
