Disulfides from the Brown Alga Dictyopteris membranacea Suppress M1 Macrophage Activation by Inducing AKT and Suppressing MAPK/ERK Signaling Pathways

Marine Drugs, 2020
Inflammation is part of the organism’s response to deleterious stimuli, such as pathogens, damaged cells, or irritants. Macrophages orchestrate the inflammatory response obtaining different activation phenotypes broadly defined as M1 (pro-inflammatory ...

Preparation and flotation performance of thionocarbamates

工程科学学报, 2023
To address the problems of byproduct treatment and pollution in thionocarbamate preparation, four novel processes for preparing O-isopropyl-N-ethyl thionocarbamate (IPETC) were designed, which can coproduce 4-(tert-butyl)benzyl mercaptan (BBSH), sodium ...

Cytosolic thioredoxin reductase 1 is required for correct disulfide formation in the ER [PDF]

, 2017
Folding of proteins entering the secretory pathway in mammalian cells frequently requires the insertion of disulfide bonds. Disulfide insertion can result in covalent linkages found in the native structure as well as those that are not, so‐called non ...

Efficient preparation of unsymmetrical disulfides by nickel-catalyzed reductive coupling strategy

Nature Communications, 2022
The preparation of disulfides mainly relies on oxidative couplings of two sulfur-containing compounds, a strategy which has side reactions and other shortcomings.

Review

, 2020
The chalcogen elements oxygen, sulfur, and selenium are essential constituents of side chain functions of natural amino acids. Conversely, no structural and biological function has been discovered so far for the heavier and more metallic tellurium ...

Protein disulfide-isomerase interacts with a substrate protein at all stages along its folding pathway [PDF]

, 2014
In contrast to molecular chaperones that couple protein folding to ATP hydrolysis, protein disulfide-isomerase (PDI) catalyzes protein folding coupled to formation of disulfide bonds (oxidative folding).
