Thionylation
Webthionylation. Reaction of IX with DMF and dimethyl-acetamide in chloroform at room temperature proceeds practically quantitatively and leads to corresponding thioamides. In this case the reagent ratio is equimolar, and the yields of thioamide exceed 90%.

WebThionylation of 2', 4'- di … Childhood bone cancer though rare, has very limited treatment choices, with poor survival rates and often involving amputation. We developed a novel molecule, 2', 4'-dihydroxy-dithion-dibenzoyl-methane and tested it on hepatic, colon, lung and osteoblast cancer cell lines.
Webthionylation (-SSG) (Fig. 1) (3, 4). Most thiol redox modifica-tions can be formed by the non-enzymatic reactions of reac-tive oxygen/nitrogen/sulfur species (ROS/RNS/RSS) with protein thiols, which has led to the widespread notion that these types of modifications are randomly distributed across the cysteine proteome. However, emerging ... WebJan 22, 2024 · thionylation of cysteine residues has been shown to diminish STAT3 transcriptional activity in HepG2 cells (97). Although the exact mechanisms by which upregulated STAT3 signaling contributes to the pathogenesis of several kidney diseases are unknown, current evidence suggests a role for the expression of STAT3 target genes. …
WebNational Center for Biotechnology Information WebThe thionylation has been also suggested as a mechanism through which protein functions can be regulated by the redox status [11]. To elucidate the molecular mechanism of S100A1 activation due to thionylation we decided to undertake, using NMR methods, a precise comparative study of structure and dynamics of ...

Webthionylation of the conserved extra cysteine is a general feature of f-type TRXs. Because TRXf fromChlamydomonasis difficult to produce and purify, we used spinach TRXf1 (SoTRXf1) for these assays.
