Using dicationic ionic liquids to upgrade the cytotoxicity and solubility of poorly water-soluble drugs

Journal of Ionic Liquids, 2023
New dicationic ionic liquids (DcILs) based on carboxylic acid-derived, N-acetyl amino acid-derived or bromide anions, and ammonium cations were synthesized and characterized.

Ionic Clusters vs Shear Viscosity in Aqueous Amino Acid Ionic Liquids [PDF]

The Journal of Physical Chemistry B, 2015
Aqueous solutions of amino acid ionic liquids (AAILs) are of high importance for applications in protein synthesis and solubilization, enzymatic reactions, templates for synthetic study, etc. This work employs molecular dynamics simulations using our own force field to investigate shear viscosity and cluster compositions of three 1-ethyl-3 ...

Salting-out in aqueous solutions of ionic liquids and K3PO4: Aqueous biphasic systems and salt precipitation [PDF]

, 2007
The salting-out effect produced by the addition of potassium phosphate, K3PO4 to aqueous solutions of water-miscible ionic liquids, viz. 1-ethyl-3-methylimidazolium ethyl sulfate, 1-butyl-3-methylimidazolium methyl sulfate, or 1-alkyl-3-methylimidazolium

Quantification of amino acids and peptides in an ionic liquid based aqueous two-phase system by LC–MS analysis

AMB Express, 2018
Aqueous two-phase systems (ATPS) occur by the mixture of two polymers or a polymer and an inorganic salt in water. It was shown that not only polymers but also ionic liquids in combination with inorganic cosmotrophic salts are able to build ATPS ...

Specification of Zwitterionic or Non-Zwitterionic Structures of Amphoteric Compounds by Using Ionic Liquids

Acta Chimica Slovenica, 2020
Some imidazolium-based ionic liquids were used to determine zwitterionic or non-zwitterionic structures of glycine and p-amino benzoic acid, as model amphoteric compounds, in their corresponding isoelectric point.

Electrochemical transistors with ionic liquids for enzymatic sensing [PDF]

, 2010
We report an enzymatic sensor based on an organic electrochemical transistor that uses a room temperature ionic liquid as an integral part of its structure and as an immobilization medium for the enzyme and the ...

A Computational Analysis of the Reaction of SO₂ with Amino Acid Anions: Implications for Its Chemisorption in Biobased Ionic Liquids

Molecules, 2022
We report a series of calculations to elucidate one possible mechanism of SO2 chemisorption in amino acid-based ionic liquids. Such systems have been successfully exploited as CO2 absorbents and, since SO2 is also a by-product of fossil fuels’ combustion,

A Systematic Review of Amino Acid-Based Adsorbents for CO₂ Capture

Energies, 2022
The rise of carbon dioxide (CO2) levels in the atmosphere emphasises the need for improving the current carbon capture and storage (CCS) technology. A conventional absorption method that utilises amine-based solvent is known to cause corrosion to process

Changes in the gut microbiota of mice orally exposed to methylimidazolium ionic liquids.

PLoS ONE, 2020
Ionic liquids are salts used in a variety of industrial processes, and being relatively non-volatile, are proposed as environmentally-friendly replacements for existing volatile liquids.

Anodic Fluorination and Cathodic Michael Addition of Schiff Bases Bearing Trifluoromethyl and Ester Groups

Electrochemistry, 2021
Anodic fluorination of N-(diphenylmethyleneamino)-2,2,2-trifluoroethane and N-[bis(methylthio)methyleneamino]-2,2,2-triphenylethane in acetonitrile containing poly(HF) salt ionic liquids afforded monofluorinated products in moderate to good yields.
