“…5,16 The latter indicates that the Li + ion solvation is facilitated by DMSO molecules, which also stabilizes the main and the intermediate (Li 2 O 2 and LiO 2 , respectively) discharge products formed during the Li-O 2 batteries operation. 5,16 Moreover, the high DN enables the formation of hydrogen bonds between DMSO molecules and some other solvents and salts in binary 17 and ternary mixtures, 18 which affect the physical properties of the electrolyte. 17 Despite these great features, DMSO has an electrochemical window limited to 4.20 V, 19 which means it can degrade during the electrochemical reactions in the Li-O 2 battery operation, forming undesirable and irreversible products, such as DMSO 2 .…”

“…Many experimental and theoretical investigations have been made into the structure of liquid solutions of DMSO, particularly around the 1:2 composition where the meltingpoint depression is greatest (e.g. Soper & Luzar, 1992;Vishnyakov et al, 2001;Bordallo et al, 2004;McLain et al, 2007;Wallace et al, 2015;Oh et al, 2017;Stachura et al, 2018;Wei et al, 2018;Yang et al, 2020). The prevailing interpretation of DMSO-water liquid data is in terms of 1:3 and 1:2 DMSOwater clusters and possible association into DMSO-(water) n -DMSO chains (Zhang et al, 2009;Idrissi et al, 2015;Verstakov et al, 2020).…”

Neutron powder diffraction data have been collected from a series of flash-frozen aqueous solutions of dimethyl sulfoxide (DMSO) with concentrations between 25 and 66.7 mol% DMSO. These reveal the existence of three stoichiometric hydrates, which crystallize on warming between 175 and 195 K. DMSO trihydrate crystallizes in the monoclinic space group P21/c, with unit-cell parameters at 195 K of a = 10.26619 (3), b = 7.01113 (2), c = 10.06897 (3) Å, β = 101.5030 (2)° and V = 710.183 (3) Å3 (Z = 4). Two of the symmetry-inequivalent water molecules form a sheet of tiled four- and eight-sided rings; the DMSO molecules are sandwiched between these sheets and linked along the b axis by the third water molecule to generate water–DMSO–water tapes. Two different polymorphs of DMSO dihydrate have been identified. The α phase is monoclinic (space group P21/c), with unit-cell parameters at 175 K of a = 6.30304 (4), b = 9.05700 (5), c = 11.22013 (7) Å, β = 105.9691 (4)° and V = 615.802 (4) Å3 (Z = 4). Its structure contains water–DMSO–water chains, but these are polymerized in such a manner as to form sheets of reniform eight-sided rings, with the methyl groups extending on either side of the sheet. On warming above 198 K, α-DMSO·2H2O undergoes a solid-state transformation to a mixture of DMSO·3H2O + anhydrous DMSO, and there is then a stable eutectic between these two phases at ∼203 K. The β-phase of DMSO dihydrate has been observed in a rapidly frozen eutectic melt and in very DMSO-rich mixtures. It is observed to be unstable with respect to the α-phase; above ∼180 K, β-DMSO·2H2O converts irreversibly to α-DMSO·2H2O. At 175 K, the lattice parameters of β-DMSO·2H2O are a = 6.17448 (10), b = 11.61635 (16), c = 8.66530 (12) Å, β = 101.663 (1)° and V = 608.684 (10) Å3 (Z = 4), hence this polymorph is just 1.16% denser than the α-phase under identical conditions. Like the other two hydrates, the space group appears likely, on the basis of systematic absences, to be P21/c, but the structure has not yet been determined. Our results reconcile 60 years of contradictory interpretations of the phase relations in the binary DMSO–water system, particularly between mole fractions of 0.25–0.50, and confirm empirical and theoretical studies of the liquid structure around the eutectic composition (33.33 mol% DMSO).

“…Considering the possible mechanisms of the observed phenomenon of inhibition of protein synthesis in cells and cell-free systems, we can assume that they are primarily based on a change in the physicochemical properties of water, in particular its structural state and dielectric constant [21][22][23], accompanied by strengthening of hydrogen bonds [21,22], which are important in interaction of metabolites with their carriers, as well as functioning of ribosomes and enzymes involved into the translation. Apparently, an increase in the concentration of electrolytes, including Mg 2+ , is also crucial, as a result of a decrease in the free water fraction due to its binding to cryoprotective agent molecules.…”

The effect of penetrating (glycerol, DMSO) and poorly penetrating (PEG-400) cryoprotective agents on labeled amino acids incorporation into de novo synthesized proteins in the cells of mice thymus, lymph nodes, spleen and cell-free rat liver extract was studied. cryoprotective agents within the range of concentrations which provide a cryoprotective effect were found to inhibit significantly protein synthesis in cell-free systems under investigation. The most effective inhibition was exerted by polymeric cryoprotective agent PEG-400. Cryoprotective agents more efficiently inhibited protein synthesis at a cell level as compared with that in cell-free system that was likely associated with their effect on amino acids transport system. An inhibitory effect of cryoprotective agents on the protein synthesizing apparatus of cells was determined to be Mg 2+-dependent and reversible. K e y w o r d s: cryoprotective agents, incorporation of labeled amino acids, protein biosynthesis, cell-free system, lymphoid organs, Mg 2+-dependent.
