Structure, properties, and decomposition in biological systems of a new nitrosyl iron complex with 2-methoxythiophenolyls, promising for the treatment of cardiovascular diseases.

A new promising binuclear tetranitrosyl iron complex with 2-methoxythiophenolyl of the composition [Fe(CHOS)(NO)] (complex 1), which acts on the therapeutic targets of cardiovascular diseases, guanylate and adenylate cyclase, has been synthesized. X-ray diffraction data show the presence of two isoforms of complex 1; according to quantum chemical calculations, the structure of only the trans isomer is stable in solutions. The processes of transformation of complex 1 in DMSO, in aqueous solutions, as well as in the presence of bovine serum albumin, reduced glutathione, and mucin were studied.

Solubility Enhancement of Dihydroquercetin via "Green" Phase Modification.

Dihydroquercetin (DHQ) is a promising antioxidant for medical applications. The poor water solubility of this flavanonol at ambient conditions inhibits its implementation in clinical practice as an injectable dosage form. Thus, increasing water solubility is a critical step toward solving this problem.

Partial Substitution of Pb in CsPbI as an Efficient Strategy To Design Fairly Stable All-Inorganic Perovskite Formulations.

All-inorganic lead halide perovskites, for example, CsPbI, are becoming more attractive for applications as light absorbers in perovskite solar cells because of higher thermal and photochemical stability as compared to their hybrid analogues. However, a specific drawback of the CsPbI absorber consists of the rapid phase transition from black to yellow nonphotoactive phase at low temperatures (e.g.

Oxygen Atom Transfer in the Oxidation of Dimethyl Sulfoxide by Oxoammonium Cations.

Cyclic oxoammonium salts and DMSO are known as important reagents for their diverse and unique reactivity. In the present work, we have studied the reaction of six- and five-membered oxoammonium salts with DMSO. The reaction includes ∼100% selective transfer of the O atom from the >N═O group to the S atom of DMSO and structural rearrangement of the remaining cationic framework, leading to the formation of hydrolytically unstable iminium salts.

Multifunctional Compound Combining Conductivity and Single-Molecule Magnetism in the Same Temperature Range.

We report the first highly conducting single-molecule magnet, (BEDO)[ReF]·6HO [1; BEDO = bis(ethylenedioxo)tetrathiafulvalene], whose conductivity and single-molecule magnetism coexist in the same temperature range. The compound was synthesized by BEDO electrocrystallization in the presence of (PhP)[ReF]·2HO and characterized by crystallography and measurements of the conductivity and alternating-current magnetic susceptibility.
