Investigating tryptophan quenching of fluorescein fluorescence under protolytic equilibrium
(2009)Fluorescein is one of most used fluorescent labels for characterizing biological systems, such as proteins, and is used in fluorescence microscopy. However, if fluorescein is to be used for quantitative measurements involving ... -
Investigation of non-covalent interactions of metal complexes with DNA in cell-free systems
(Schweizerische Chemische Gesellschaft, 2017-03-01)Non-covalent interactions of metallo compounds with DNA range from the simple, unspecific electrostatic binding of a positively charged metal complex to the sequence-selective recognition of DNA binding sites due to shape, ... -
Investigation of the formation of drug-drug cocrystals and coamorphous systems of the antidiabetic drug gliclazide
(Elsevier, 2019-02-23)The antidiabetic drug gliclazide (GLZ) has a slow absorption rate and a low bioavailability due to its poor solubility. GLZ is often prescribed along with an antihypertensive, as many diabetic patients have coexistent ... -
Kernel principal component analysis residual diagnosis (KPCARD): an automated method to remove cosmic ray artefacts in Raman spectra.
(2016)A new, fully automated, rapid method, referred to as kernel principal component analysis residual diagnosis (KPCARD), is proposed for removing cosmic ray artifacts (CRAs) in Raman spectra, and in particular for large Raman ... -
A kinetic modelling study of alcohols operating regimes in a HCCI engine
(SAE International, 2017-09-04)Pursuing a sustainable energy scenario for transportation requires the blending of renewable oxygenated fuels such as alcohols into commercial hydrocarbon fuels. From a chemical kinetic perspective, this requires the ... -
A kinetics and dynamics study on the auto-ignition of dimethyl ether at low temperatures and low pressures
(Elsevier, 2020-09-14)Though the combustion chemistry of dimethyl ether (DME) has been widely investigated over the past decades, there remains a dearth of ignition data that examines the low-temperature, low-pressure chemistry of DME. In this ... -
Lectins: getting familiar with translators of the sugar code
(MDPI, 2015-01-22)The view on the significance of the presence of glycans in glycoconjugates is undergoing a paradigmatic change. Initially mostly considered to be rather inert and passive, the concept of the sugar code identifies glycans ... -
Lewis acid induced anomerization of se-glycosides. Application to synthesis of alpha-Se-GalCer
(American Chemical Society, 2016-01-22)The TiCl4 induced anomerization of selenium glycosides of galacturonic acid derivatives is reported. The reaction was successful for galacturonic acid when various alkyl, alkenyl, alkynyl, saccharide, steroid, and lipid ... -
Lewis acid promoted anomerisation of alkyl O- and S-xylo-, arabino- and fucopyranosides
(Elsevier, 2018-11-24)Pentopyranoside and 6-deoxyhexopyranosides, such as those from d-xylose, l-arabinose and l-fucose are components of natural products, oligosaccharides or polysaccharides. Lewis acid promoted anomerisation of some of their ... -
Ligand design for somatostatin receptor isoforms 4 and 5
(Elsevier, 2018-11-17)The somatostatin receptor (SSTR) isoforms, SSTR-4 and SSTR-5 are targets in numerous disorders and diseases. Although there has been some success in achieving selective isoform inhibition, structure-based drug design and ... -
Light driven styrene epoxidation and hydrogen generation using H2O as an oxygen source in a photoelectrosynthesis cell
(Royal Society of Chemistry, 2015-10-02)A dye-sensitized photoelectrosynthesis cell (DSPEC) has been prepared for the oxidation of alkenes to epoxides and evolution of hydrogen using water as an oxygen source and sunlight. A Ru oxidation catalyst, 2,2+ , is ... -
Liquid-crystal-mediated force between a cylindrical nanoparticle and substrate
