The Oxidized Protein Repair Enzymes Methionine Sulfoxide Reductases and Their Roles in Protecting against Oxidative Stress, in Ageing and in Regulating Protein Function

Antioxidants, 2018
Cysteine and methionine residues are the amino acids most sensitive to oxidation by reactive oxygen species. However, in contrast to other amino acids, certain cysteine and methionine oxidation products can be reduced within proteins by dedicated ...

The DmsABC Sulfoxide Reductase Supports Virulence in Non-typeable Haemophilus influenzae

Frontiers in Microbiology, 2021
Although molybdenum-containing enzymes are well-established as having a key role in bacterial respiration, it is increasingly recognized that some may also support bacterial virulence.

Dimethyl sulfoxide: a central player since the dawn of cryobiology, is efficacy balanced by toxicity?

Regenerative medicine, 2020
Dimethyl sulfoxide (DMSO) is the cryoprotectant of choice for most animal cell systems since the early history of cryopreservation. It has been used for decades in many thousands of cell transplants.

2,5-[C₄+C₂] Ringtransformation of Pyrylium Salts with α-Sulfinylacetaldehydes

Molecules, 2023
A rapid synthesis of chiral sulfoxide-functionalized meta-terphenyl derivatives by a 2,5-[C4+C2] ring transformation reaction of pyrylium salts with in situ generated enantiomerically pure α-sulfinylacetaldehydes is described in this paper.

Aplisulfamines, New Sulfoxide-Containing Metabolites from an Aplidium Tunicate: Absolute Stereochemistry at Chiral Sulfur and Carbon Atoms Assigned Through an Original Combination of Spectroscopic and Computational Methods

Marine Drugs, 2012
Two new sulfoxide-containing metabolites, aplisulfamines A (1) and B (2), have been isolated from an Aplidium sp. collected in the Bay of Naples. Their planar structure and geometry of a double bond were readily determined by using standard methods ...

Crystal structure of methyl (2R,3S)-3-[(tert-butylsulfinyl)amino]-2-fluoro-3-phenylpropanoate

Acta Crystallographica Section E: Crystallographic Communications, 2015
The title compound, C14H20FNO3S, contains two chiral carbon centres and the absolute configuration has been confirmed as (2R,3S). In the crystal, adjacent molecules are linked by weak C—H...O hydrogen bonds, generating zigzag chains along the a-axis ...

Extracting the sample response function from experimental two-dimensional terahertz-infrared-visible spectra [PDF]

, 2022
Terahertz molecular motions are often probed by high-frequency molecular oscillators in different types of non-linear vibrational spectroscopy. Recently developed two-dimensional terahertz-infrared-visible spectroscopy allows direct measuring of this coupling and, thus, obtaining site-specific terahertz vibrational spectrum.

N-Methyl-(R)-3-(tert-Butyl)-Sulfinyl-1,4-Dihydropyridine: A Novel NADH Model Compound

Molecules, 2007
We have synthesized a novel chiral NADH model compound, N-methyl-(R)-3-(tert-butyl)-sulphinyl-1,4-dihydropyridine with high enantioselectivity and used it in the reduction of methyl benzoylformate, producing (S)-methyl mandelate in 95% ee.
