Design, synthesis and biological activity of selective hCAs inhibitors based on 2-(benzylsulfinyl)benzoic acid scaffold [PDF]

, 2019
A large library of derivatives based on the scaffold of 2-(benzylsulfinyl)benzoic acid were synthesised and tested as atypical inhibitors against four different isoforms of human carbonic anhydrase (hCA I, II, IX and XII, EC 4.2.1.1).

The applicability of sulfoxide Michael acceptor – 2­-(S)-­[(4­-methylphenyl)sulfinyl]-­2­-cyclopenten­-1­-one in constructing the carbon skeleton of 9,11­-secosterols [PDF]

Proceedings of the Estonian Academy of Sciences
A possibility of use of the Michael addition reaction of the A,B­-ring fragment enolate to sulfoxide 2­-(S)-­[(4­-methylphenyl)sulfinyl]-­2­-cyclopenten­-1­-one for constructing the main skeleton of 9,11­-secosterols was studied.

Can acyclic conformational control be achieved via a sulfur-fluorine gauche effect? [PDF]

, 2015
The gauche conformation of the 1,2-difluoroethane motif is known to involve stabilising hyperconjugative interactions between donor (bonding, σC-H) and acceptor (antibonding, σ*C-F) orbitals.

Apparent molar volume anomaly in water-dimethyl sulfoxide liquid mixtures. Molecular dynamics computer simulations [PDF]

Condensed Matter Physics, 2022, vol. 25, No. 4, 44201, 2023
We have studied the composition dependence of density of liquid water-DMSO mixtures at different temperatures by using the isobaric-isothermal (NPT) molecular dynamics computer simulations. The non-polarizable semi-flexible, P1 and P2 models for the DMSO molecule combined with the TIP4P-2005 water model are considered.

Sulfur-Containing Monoterpenoids as Potential Antithrombotic Drugs: Research in the Molecular Mechanism of Coagulation Activity Using Pinanyl Sulfoxide as an Example

Frontiers in Pharmacology, 2018
In this article we present the synthesis of enantiomerically pure sulfoxide and study the influence of this compound on hemostasis. Detailed NMR studies and molecular dynamics simulations using sodium dodecyl sulfate (SDS) membrane models indicated that ...

Characterization of Sulfides in Atmospheric Residue Fractions Using Selective Oxidation Followed by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

Energies, 2022
An improved analytical method was developed for identifying sulfide compounds from aromatic fractions in Lungu atmospheric residue (LGAR). Sulfides in residue aromatics were selectively oxidized into sulfoxides using tetrabutyl ammonium periodate (TBAP ...

Alternatives to free molecular halogens as chemoselective reactants: Catalysis of organic reactions with reusable complexes of halogen metal salts [PDF]

, 2012
Organometallic complexes of halogen metallic salts have been used as catalysts in different organic reactions, mainly the oxidation of organic compounds. Their use has not only allowed the reduction of the amounts of catalyst (since they can be reused)

Diethyl Sulfoxide as a Novel Neutral Ligand in the Platinum Complex Anion [PDF]

arXiv, 2021
Diethyl sulfoxide (DESO) is far less known than its shorter-alkyl-chain homolog, dimethyl sulfoxide. Although the field of senior dialkyl sulfoxides does not currently exhibit an explosive growth, new fundamental and applied research works routinely appear from a few research groups in the world.

Effect of glycerol and dimethyl sulfoxide on the phase behavior of lysozyme: Theory and experiments [PDF]

The Journal of Chemical Physics 136: 015102, 2012, 2011
Salt, glycerol and dimethyl sulfoxide (DMSO) are used to modify the properties of protein solutions. We experimentally determined the effect of these additives on the phase behavior of lysozyme solutions. Upon the addition of glycerol and DMSO, the fluid-solid transition and the gas-liquid coexistence curve (binodal) shift to lower temperatures and the
