Crown ethers are heterocycles that, in their simplest form, are cyclic oligomers of dioxane.
The essential repeating unit of any simple crown ether is ethyleneoxy, ie,-CH2CH2O-, which …

This is a review of work pertaining to noncovalent binding interactions involving primarily the
cationic guanidinium group and the anionic sulf [on] ate and phosph [on] ate groups. 1 To a …

The initial stages of drug discovery are increasingly reliant on development and
improvement of analytical methods to investigate protein–protein and protein–ligand …

Tandem mass spectrometry (MS) of large protein complexes has proven to be capable of
assessing the stoichiometry, connectivity, and structural details of multiprotein assemblies …

A crown ether based, photolabile radical precursor which forms noncovalent complexes with
peptides has been prepared. The peptide/precursor complexes can be electrosprayed …

Absolute 18-crown-6 (18C6) affinities of five amino acids (AAs) are determined using guided
ion beam tandem mass spectrometry techniques. The AAs examined in this work include …

Absolute 18-crown-6 (18C6) affinities of nine protonated peptidomimetic bases are
determined using guided ion beam tandem mass spectrometry techniques. The bases (B) …

Hybrid polymer–peptide conjugates offer the potential for incorporating biological function
into synthetic materials. The secondary structure of short helical peptides, however …

A series of crown ethers, 12-crown-4, 15-crown-5, 18-crown-6, and dibenzo-30-crown-10,
are examined as a possible means of shifting the mobilities of peptide ions. In this approach …

A novel Schiff base and its Pb2+-complex have been synthesised and exploited as
colorimetric and fluorescent–colorimetric sensors respectively targeting the detection of …
