The applicability of sulfoxide Michael acceptor – 2­-(S)-­[(4­-methylphenyl)sulfinyl]-­2­-cyclopenten­-1­-one in constructing the carbon skeleton of 9,11­-secosterols [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
A possibility of use of the Michael addition reaction of the A,B­-ring fragment enolate to sulfoxide 2­-(S)-­[(4­-methylphenyl)sulfinyl]-­2­-cyclopenten­-1­-one for constructing the main skeleton of 9,11­-secosterols was studied.

NaSH-HCl mediated reduction of sulfoxides into sulfides under organic solvent-free reaction conditions

open access: yesGreen Chemistry Letters and Reviews, 2020
NaSH·H2O and 37% aqueous solution of HCl were employed in reduction of sulfoxides to sulfides at room or elevated temperature in the absence of organic reducing agent and solvent-free reaction conditions. Operationally simple transformation took place in

A Click Chemistry Approach towards Flavin-Cyclodextrin Conjugates—Bioinspired Sulfoxidation Catalysts

open access: yesMolecules, 2015
A click chemistry approach based on the reaction between alkynylflavins and mono(6-azido-6-deoxy)-β-cyclodextrin has proven to be a useful tool for the synthesis of flavin-cyclodextrin conjugates studied as monooxygenase mimics in enantioselective ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Microwave-assisted photooxidation of sulfoxides

open access: yesScientific Reports, 2021
We demonstrated microwave-assisted photooxidation of sulfoxides to the corresponding sulfones using ethynylbenzene as a photosensitizer. Efficiency of the photooxidation was higher under microwave irradiation than under conventional thermal heating ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

open access: yesFEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Transient Sulfenic Acids in the Synthesis of Biologically Relevant Products

open access: yesMolecules, 2018
Sulfenic acids as small molecules are too unstable to be isolated and their transient nature offers the possibility to involve them in concerted processes that lead to the obtainment of functional groups such as sulfoxides, sulfones, and disulfides.
