Liquid-exfoliated 2D transition metal disulfides (TMDs) are potential substitutes for poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) as hole transport layers (HTLs) in Organic Solar Cells (OSCs). Herein, high-yield and high-quality WS

Ligand-induced transition in conformations of vicinal cysteine disulfides in proteins.

Proteins

Reddy KKA, Jayashree M, Govindu PCV, Gowd KH.

Proteins. 2021 Jun;89(6):599-613. doi: 10.1002/prot.26039. Epub 2021 Mar 25.

Vicinal cysteine disulfides are thought to be associated with specific conformations of cysteine disulfides due to the restricted rotation of single bonds in an eight-membered cyclic disulfide loop. Conformations of vicinal cysteine disulfides are analyzed using χ

Base-free catalytic aerobic oxidation of mercaptans over MOF-derived Co/CN catalyst with controllable composition and structure.

Journal of colloid and interface science

Zhang C, Gao H, Hai G, Zeng Y, Wang X, Xing L, Zhao J, Wang G, Shu X.
PMID: 34695736

The oxidation of mercaptans under mild and base-free conditions is of vital importance in terms of economy and environment for petroleum processing industry. Here, we developed a series of MOF-derived cobalt-based nitrogen-doped (N-doped) carbon (Co/CN-x) catalysts for the base-free...

Synthesis and Biological Evaluation of Dithiobisacetamides as Novel Urease Inhibitors.

ChemMedChem. 2021 Oct 23; doi: 10.1002/cmdc.202100618. Epub 2021 Oct 23.

Thirty-eight disulfides containing N-arylacetamide were designed and synthesized in an effort to develop novel urease inhibitors. Biological evaluation revealed that some of the synthetic compounds exhibited strong inhibitory potency against both cell-free urease and urease in intact cell with...

Production of Alkyl Aryl Sulfides from Aromatic Disulfides and Alkyl Carboxylates via a Disilathiane-Disulfide Interchange Reaction.

Chemistry, an Asian journal

PMID: 34693645
Chem Asian J. 2021 Oct 25; doi: 10.1002/asia.202101101. Epub 2021 Oct 25.

The results of this study show that disilathiane is an effective mediator in the synthesis of alkyl aryl sulfides with disulfides and alkyl carboxylates. Mechanistic studies suggest that disilathiane promotes cleavage of the sulfur-sulfur bond of disulfides to generate...

Specific domain V reduction of beta-2-glycoprotein I induces protein flexibility and alters pathogenic antibody binding.

Beta-2-glycoprotein I (β2GPI) is a blood protein and the major antigen in the autoimmune disorder antiphospholipid syndrome (APS). β2GPI exists mainly in closed or open conformations and comprises of 11 disulfides distributed across five domains. The terminal Cys288/Cys326 disulfide...

Thiol-Mediated Uptake.

JACS Au

Laurent Q, Martinent R, Lim B, Pham AT, Kato T, López-Andarias J, Sakai N, Matile S.

This Perspective focuses on thiol-mediated uptake, that is, the entry of substrates into cells enabled by oligochalcogenides or mimics, often disulfides, and inhibited by thiol-reactive agents. A short chronology from the initial observations in 1990 until today is followed...

RP-HPLC method for simultaneous quantification of free and total thiol groups in native and heat aggregated whey proteins.

MethodsX

MethodsX. 2020 Oct 17;7:101112. doi: 10.1016/j.mex.2020.101112. eCollection 2020.

Disulfide formation of whey proteins during heat treatment via thiol oxidation is important with regard to techno-functional properties. Due to the formation of other oxidation products than disulfides, the decrease in free thiol concentration is not proportional to the...

A non-immunological role for γ-interferon-inducible lysosomal thiol reductase (GILT) in osteoclastic bone resorption.
