Transition-metal-catalyzed synthesis of phenols and aryl thiols

open access: yesBeilstein Journal of Organic Chemistry, 2017
Phenols and aryl thiols are fundamental building blocks in organic synthesis and final products with interesting biological activities. Over the past decades, substantial progress has been made in transition-metal-catalyzed coupling reactions, which ...

Patients with pemphigus vulgaris under pathology and on the background of prolonged use of high doses of glucocorticosteroid therapy – the possibility of influencing the glutathione system

open access: yesJournal of Education, Health and Sport, 2020
Introduction. Pemphigus vulgaris (PV) is a life-threatening disease of the skin and mucous membranes that is associated with IgG antibodies that target several types of keratinocyte antigens and cause epidermal lysis (acantholysis) via intracellular ...

Effects of storage conditions on thiol disulfide homeostasis

open access: yesMedicine Science, 2021
We planned this study to research the effect of freeze-thaw number and storage temperatures on the tests of thiol-disulfide homeostasis. Dynamic thiol-disulfide homeostasis has a crucial role in antioxidant defense reactions.

Rapid and Thiol-Specific High-Throughput Assay for Simultaneous Relative Quantification of Total Thiols, Protein Thiols, and Nonprotein Thiols in Cells [PDF]

open access: yesAnalytical Chemistry, 2014
Thiol groups in biological molecules play a significant role in various physiological functions and pathological conditions. Thiols are divided into two major groups: protein thiols and nonprotein thiols. Numerous methods have been reported for thiol assays.

Synthesis and crystal structure of (E)-1,2-bis[2-(methylsulfanyl)phenyl]diazene

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2019
The title compound, C14H14N2S2, was obtained by transmetallation of 2,2′-bis(trimethylstannyl)azobenzene with methyl lithium, and subsequent quenching with dimethyl disulfide.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
