Degradation of Methylene Blue with a Cu(II)-Quinoline Complex Immobilized on a Silica Support as a Photo-Fenton-Like Catalyst.

A Cu(II)-quinoline complex immobilized on a silica support was prepared to enhance the degradation of dyes. Mesoporous silica functionalized with this Cu(II) complex was turned into a photo-Fenton-like catalyst. Various techniques were used to characterize the resulting material, and the catalytic activity was determined by the degradation of methylene blue (MB) under UV light irradiation.

Pineapple fruit improves vascular endothelial dysfunction, hepatic steatosis, and cholesterol metabolism in rats fed a high-cholesterol diet.

Hypercholesterolaemia is a significant risk factor for developing vascular disease and fatty liver. Pineapple (), a tropical fruit widely cultivated in Asia, is reported to exhibit antioxidant and cholesterol-lowering activity; however, the potential hypolipidaemic mechanisms of pineapple fruit remain unknown. Therefore, we aimed to identify the anti-hypercholesterolaemic mechanism of pineapple fruit and to study the effect of pineapple fruit intake on hypercholesterolaemia-induced vascular dysfunction and liver steatosis in a high-cholesterol diet (HCD)-fed rats.

Pineapple consumption reduced cardiac oxidative stress and inflammation in high cholesterol diet-fed rats.

Background: Hypercholesterolemia is a major risk factor for cardiovascular disease. It has been reported that pineapple contains healthy nutrients and phytochemicals associated with antioxidant and anti-inflammatory capacities. No investigation exists concerning the effect of pineapple consumption modulating hypercholesterolemia-induced cardiac damage in high-cholesterol diet (HCD)-fed rats.

Synthesis, characterization and anticancer activity of Fe(II) and Fe(III) complexes containing N-(8-quinolyl)salicylaldimine Schiff base ligands.

A series of Fe(II) complexes (1-4) and Fe(III) complexes (5-8) from Fe(II)/(III) chloride and N-(8-quinolyl)-X-salicylaldimine Schiff base ligands (Hqsal-X/X: X = Br, Cl) were successfully synthesized and characterized by spectroscopic (FT-IR, H-NMR), mass spectrometry, thermogravimetric analysis (TGA), and single crystal X-ray crystallographic techniques. The interaction of complexes 1-8 with calf thymus DNA (CT-DNA) was determined by UV-Vis and fluorescence spectroscopy. The complexes exhibited good DNA-binding activity via intercalation.

Crystal structure of 3-[2-(1,3-thia-zol-2-yl)diazen-1-yl]pyridine-2,6-di-amine monohydrate.

In the title hydrated azo compound, CHNS·HO, the two aromatic groups are close to coplanar with the dihedral angle between the mean planes of the thia-zole and pyridine rings being 2.9 (2)°. The organic mol-ecule adopts an configuration with respect to the double bond of the azo bridge.

Cyclopropenylidene carbene ligands in palladium catalysed coupling reactions: carbene ligand rotation and application to the Stille reaction.

Reaction of [Pd(PPh(3))(4)] with 1,1-dichloro-2,3-diarylcyclopropenes gives complexes of the type cis-[PdCl(2)(PPh(3))(C(3)(Ar)(2))] (Ar = Ph 5, Mes 6). Reaction of [Pd(dba)(2)] with 1,1-dichloro-2,3-diarylcyclopropenes in benzene gave the corresponding binuclear palladium complexes trans-[PdCl(2)(C(3)(Ar)(2))](2) (Ar = Ph 7, p-(OMe)C(6)H(4)8, p-(F)C(6)H(4)9). Alternatively, when the reactions were performed in acetonitrile, the complexes trans-[PdCl(2)(NCMe)(C(3)(Ar)(2))] (Ar = Ph 10, p-(OMe)C(6)H(4)11 and p-(F)C(6)H(4)) 12) were isolated.
