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.

Pinacol as a new green reducing agent: molybdenum-catalyzed chemoselective reduction of sulfoxides and nitroaromatics [PDF]

open access: yes, 2012
Pinacol is disclosed as a new chemoselective and environmentally benign reducing agent for sulfoxides and nitroaromatics assisted by readily available dichlorodioxomolybdenum(VI) complexes as catalysts.

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma

open access: yesMolecular Oncology, EarlyView.
We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

Molybdenum-catalyzed enantioselective sulfoxidation controlled by a nonclassical hydrogen bond between coordinated chiral imidazolium-based dicarboxylate and peroxido ligands [PDF]

open access: yes, 2018
Chiral alkyl aryl sulfoxides were obtained by molybdenum-catalyzed oxidation of alkyl aryl sulfides with hydrogen peroxide as oxidant in mild conditions with high yields and moderate enantioselectivities.

Metal-organic frameworks as selective or chiral oxidation catalysts [PDF]

open access: yes, 2014
Since the discovery of Metal Organic Frameworks (MOFs) in the early 1990s, the amount of new structures has grown exponentially. A MOF typically consists of inorganic nodes that are connected by organic linkers to form crystalline, highly porous ...

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Aetiology and treatment of epidermal depigmentory disorder in humans [PDF]

open access: yes, 2012
The epidermal depigmentary trigger in humans at post-natal level may occur with the toxification of skin organ with the endogenously produced melanocytotoxic hydrogen peroxide and subsequent formation of hydrogen peroxide- melanolipoprotein conjugate ...

Green process for adipic acid synthesis: oxidation by hydrogen peroxide in water micromelusions using Benzalkonium Chloride C12-14 surfactant [PDF]

open access: yes, 2012
Adipic acid was synthesized by the oxidation of cyclohexene using 30% hydrogen peroxide in a microemulsion in the presence of sodium tungstate as catalyst.

Benzyl 2-ethylhexyl sulfoxide [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2009
The mol-ecule of the title compound, C(15)H(24)OS, shows S conformations for the S atom and the asymmetric C atom of the isooctyl group. The long axes of the mol-ecules are directed along the c axis. In the crystal structure, the mol-ecules are linked by weak inter-molecular bifurcated C-H⋯O hydrogen bonds.
