Extraction of glycogen with dimethyl sulfoxide

Archives of Biochemistry and Biophysics, 1962
Abstract Glycogen has been isolated from rat livers by dimethyl sulfoxide extraction in a form which appears to be more representative of “native” glycogen than that isolated by other methods. Evidence has been obtained that the normal type of alkaline degradation might partially be the cause of the lower molecular weight of classical Pfluger ...

An Iron(II) Chloride‐Promoted Radical Cascade Methylation or α‐Chloro‐β‐methylation of N‐Arylacrylamides with Dimethyl Sulfoxide

, 2017
A free radical-initiated methylation and/or α-chloro-β-methylation of N-arylacrylamides with dimethyl sulfoxide under the analogous Fenton reaction condition has been developed, which provides an effective and facile cascade strategy for the synthesis of

An Efficient Synthesis of Polysubstituted Pyridines via C sp 3H Oxidation and CS Cleavage of Dimethyl Sulfoxide

, 2016
An expedient cleavage of the CS bond of dimethyl sulfoxide (DMSO) has been developed for the preparation of substituted pyridines from ketones. In this transformation, the co-product formic acid was formed from ammonium formate, which acted as an ...

Performance of Dimethyl Sulfoxide and Brønsted Acid Catalysts in Fructose Conversion to 5-Hydroxymethylfurfural

, 2017
The performance of DMSO for the dehydration of fructose to 5-hydroxymethylfurfural (HMF) in the presence and absence of Bronsted acid has been theoretically investigated at G4 level in DMSO solution.

Denaturation of RNA with dimethyl sulfoxide

Biopolymers, 1968
AbstractThe denaturation of single‐stranded and double‐stranded RNA's in solutions with varying proportions of dimethyl sulfoxide has been followed by changes in absorbancy, optical rotation, and—with a double‐stranded form of bacteriophage of MS2 RNA— infectivity for bacterial spheroplasts.

THE HUMAN TOXICOLOGY OF DIMETHYL SULFOXIDE [PDF]

Annals of the New York Academy of Sciences, 1975
On November 11, 1965, research on DMSO in the United States came to an abrupt halt. A conference between the Food and Drug Administration and the pharmaceutical companies who were involved in the research was called because lens changes had been observed in a number of mammalian species. No changes ha been observed in man or any primates.

In Situ Study of Oxygen Reduction in Dimethyl Sulfoxide (DMSO) Solution: A Fundamental Study for Development of the Lithium–Oxygen Battery

, 2015
To develop a lithium–oxygen (Li-O2) battery with an extremely high specific energy, mechanisms for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) on a flat gold electrode in the aprotic polar solvent of dimethyl sulfoxide ...

DIMETHYL SULFOXIDE AND THE CALCIUM PARADOX

Annals of the New York Academy of Sciences, 1983
Abstract : The results indicate that DMSO does not protect rat hearts against the effects of calcium-free perfusion that predispose the myocardium to the calcium paradox. The calcium-paradox damage is reduced, however, when DMSO is present during the reperfusion phase.

I2- or NBS-catalyzed highly efficient α-hydroxylation of ketones with dimethyl sulfoxide.

Organic Letters, 2015
An efficient method for the direct preparation of high synthetic valuable α-hydroxycarbonyls is described. The simple and readily available I2 or NBS was used as catalyst. DMSO acts as the oxidant, oxygen source, and solvent.
