The crystal structure of the pyridine adduct of nickel (2-chlorophenoxy)-ethanote, {[Ni2(2-CPA)4(py)4(H2O)] · H2O}, has been determined from three dimensional X-ray data at 293 K. Crystals of the complex are triclinic, space group P1, with two dimers in a unit cell of dimensions a = 21.740(5), ...

Comparative studies were made of the use as acyl acceptor of organosilicon compounds [Me3Si(CH2)nOH] and the corresponding carbon compounds [Me3C(CH2)nOH] in the stereoselective esterification of 2-(4-chlorophenoxy)propanoic acid by the use of lipase OF 360 of Candida cylindracea in water-satura...

An alternative and cost effective route for the resolution in high ees (95–99%) of (±)-mandelic- and (±)-2-(chlorophenoxy)propionic- acid derivatives is reported. The key step involves the covalent derivatization and separation of their diastereomeric amides with (R)- or (S)-α-arylethylamines.

This deals with fabrication of macromolecular prodrugs (MPDs) of salicylic acid (SA) and aspirin (ASP) based on a hydrophilic cellulose ether, hydroxyethyl cellulose (HEC). Degrees of substitution (DS) of SA and ASP per HEC repeating unit (HEC-RU) were achieved ranging from 0.60 to 2.18 and 0.53...

Salicylates are a group of phenolic compounds that are found naturally in plants. They exert anti-inflammatory and pro-apoptosis activities. Three salicylates (acetyl salicylic acid, ASA; acetyl salicylate calcium, ASCa and salicylate calcium, SACa) were tested in human fibrosarcoma cells for th...

Polypyrrole (PPy) films containing heparin (Hep), salicylate (Sa) or both anions were electrochemically deposited as single layers or bilayers onto Nitinol (NiTi) alloy. The PPy deposition onto the bare alloy was achieved through an anodic electropolymerization in the presence of the anions. The...

Layered double hydroxides (LDHs), have been known for many decades as catalyst and ceramic precursors, traps for anionic pollutants, and additives for polymers. Recently, their successful synthesis on the nanometer scale opened up a whole new field for their application in nanomedicine. Here we ...

Flake-like nanoporous carbon has been synthesized by the direct carbonization of aluminium salicylate coordination polymer that serves as hard templates and carbon sources. It reveals that the carbonization temperature plays a crucial role in the formation of nanoporous carbon. The correlation b...

(1S,2E,4R,6R,-7E,11E)-2,7,11-cembratriene-4,6-diol (4R) is a precursor to key flavor ingredients in leaves of Nicotiana species. The present study shows 4R decreased brain damage in rodent ischemic stroke models. The 4R-pretreated mice had lower infarct volumes (26.2 ± 9.7 mm3) than those in co...

CdTe quantum dots was synthesized and used to quantitative analysis of Ponceau 4R in solution. With the excitation wavelength of 380 nm the emission of CdTe quantum dots was quenched obviously by Ponceau 4R. In order to detect Ponceau 4R in mild condition the influences of fluorescence emission ...

ObjectiveInterleukins are important molecules involved in tumor formation. In this study, the association between renal cell carcinoma (RCC) risk and single nucleotide polymorphisms (SNPs) on IL-4/IL-13/IL-4R was assessed.

A Gram-negative chlorate-reducing bacterial strain XM-1 was isolated. The 16S rRNA gene sequence identified the isolate as Ochrobactrum anthropi XM-1, which was the first strain of genus Ochrobactrum reported having the ability to reduce chlorate. The optimum growth temperature and pH for strain...

Procedures are described for the determination of arsenite, arsenate and monomethylarsonic acid in aqueous samples. The arsenicals (after reduction of arsenic to the tervalent state) readily react with 2,3-dimercaptopropanol (BAL) to yield their BAL complexes. The products are extracted with ben...

A new titrimetric method for the microdetermination of stannous tin, e.g., stannous chloride is proposed. The mechanism of the reaction in the presence of dilute hydrochloric acid is discussed. The determination of stannous tin is done on concentrations ranging from 10 mg to 100 μg. The experim...

Scratches were made to the depth of the upper dermis on the abdomen of rabbits. The scratches were covered by patch tests for 18 hours with solutions of stannous fluoride or stannous chloride. Both these substances produced a destructive reaction with intraepidermal polymorphonuclear leukocyte p...

A new class of low-cost and easy-to-prepare monodentate phosphite ligands has been developed from readily accessible d-mannitol as starting material through a two-step transformation. Additionally, a simple and reliable protocol to synthesize neutral ruthenium phosphite complexes is reported. Fo...

Three new gallium phosphites A[Ga(HPO3)2], where A = K (1), NH4 (2), Rb (3), have been synthesized by using mild hydrothermal conditions under autogeneous pressure. Their structures have been determined by single-crystal X-ray diffraction. These compounds crystallize in the hexagonal P63mc space...

Considering that the mechanisms for phosphite-afforded disease control remain elusive, this study investigated whether zinc (Zn) and copper (Cu) phosphites could possible potentiate common bean resistance to white mold, caused by Sclerotinia sclerotiorum, through the stimulation of biochemical d...

Late blight caused by the oomycete Phytophthora infestans is one of the most severe diseases of potato (Solanum tuberosum L.) and tomato (Solanum lycopersicum L.). In this study, field trials were conducted in a cool tropical highland of Ethiopia for three consecutive years to investigate the ef...
