The manganese(II) [Mn(II)] forms on soybean roots were investigated to determine the main factors affecting the distribution of Mn(II) forms and the relationship with Mn(II) plant toxicity. Fresh roots of soybean obtained from solution culture experiments were reacted with Mn(II) in solutions, a...

This study investigated the performance of two different strains of Serratia marcescens on the manganese (II) removal and the effects of the nutrient-rich (NB medium) and nutrient-poor culture (K medium) media on this process. In the NB medium, the pigmented LG1 strain and the non-pigmented CL11...

Effect of Mn doping on the low-temperature synthesis of tricalcium phosphate (TCP) polymorphs was demonstrated in α- and β-TCP polymorphs prepared by wet precipitation method under identical conditions and annealed at 700 °C. Calcium phosphates with Mn doping level in the range from 1 to 5 mo...

Moulds are able to cause spoilage in preserved foods through degradation of the preservatives using the Pad-decarboxylation system. This causes, for example, decarboxylation of the preservative sorbic acid to 1,3-pentadiene, a volatile compound with a kerosene-like odour. Neither the natural rol...

1.1. Numerous esters of phosphoric, thiophosphoric and phosphinic acids have been synthesized and are described.2.2. The activity of esters as additives for reducing wear under high loads depends on ester structure. Esters containing thiol sulphur are more active than esters containing thionic s...

m- and p-Chlorinated ω-phenoxyalcohols 1, were transformed into the corresponding lithium ω-(m- and p-lithiophenoxy)alkoxides 4, respectively, by successive deprotonation with n-butyllithium and subsequent chlorine–lithium exchange by lithium naphthalene radical anion in THF–methylcyclohexan...

Several derivatives of 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT) were examined for their inhibitory effects on the replication of human immunodeficiency virus type 1 (HIV-1) in MT-4 cells in the presence of various concentrations (10–50%) of human serum (HS). Although all HEPT de...

1,2-Dicyano-4,5-bis[2’-(2”-benzyloxyethoxy)ethoxy]benzene can act as a precursor to new functionalized phthalocyanines with liquid crystal properties.

A novel phosphorus-containing poly(trimethylene terephthalate) (PTT) derived from 2-(6-oxido-6H-dibenz〈c,e〉〈1,2〉oxaphosphorin-6-yl)-1,4-hydroxyethoxy phenylene was synthesized via solid state polymerization, and its chemical structure was confirmed with 1H NMR. The thermal stability of the r...

5-(acylethynyl)uracils 4 were synthesized from 5-iodo-2,4-dimethoxypyrimidine 1 through a palladium-catalyzed reaction with acetylenic carbinols 5, subsequent oxidation with manganese dioxide in dichloromethane, demethylation with 6 N hydrochloric acid, followed by treatment with sodium hydroxid...

[E]-6-(2-Acylvinyl)uracils and their corresponding 1-(2-hydroxyethoxy)methyl derivatives were synthesized through palladium-catalyzed reactions which involved an interesting rearrangement. Some of the acylvinyl uracils (3, 4, and 5) and the acyclonucleosides (8 and 10) showed pronounced activity...

5-(Acylethynyl)-1-(2-hydroxyethoxy)methyl uracils (2)-(6) were synthesised in excellent yields from 1-(2-acetoxyethoxy)methyl-5-iodouracil (7) utilising palladium-copper catalysed reactions. Compounds (2)-(5) were shown to be highly active against CCRF-CEM (IC50 0.6–1.6 μM) and L1210/0 cells (...

To better understand the effects of ligand configuration on hydroformylation reactions carried out in the presence of LiBPh4·3dme (dme = 1,2-dimethoxyethane), a conformationally restrained bis(phosphite) ligand derived from 1,2-bis-(2-hydroxyethoxy)benzene, {[(2,2′-O2C12H8)P(C2H4O2)]2C6H4}, 1,...

Polyesterification of adipic acid and maleic anhydride with 1,3-bis(2-hydroxyethoxy)benzene (HER) in the presence of toluene-4-sulphonic acid was carried out using melt condensation technique. The structural characterization of the synthesized polyesters had been carried out using Fourier transf...

Hypochlorite (ClO−) and temperature play crucial roles in a wide range of physiological processes, and they are also implicated in various diseases, including cancer, inflammation of tissues and so on. Therefore, it is of great importance to explore a novel method to detect ClO− and temperature ...

Yanshan petroleum coke (YPC) was subjected to oxidation with aqueous sodium hypochlorite under mild conditions followed by subsequent solvent extraction to afford various arenecarboxylic acids (ACAs). In total, 77 compounds were identified with a chromatograph/mass spectrometer, which can be cla...

It is of great significance to design a single probe, which can detect two different types of analytes. Herein, we synthesized the first dual-function fluorescent probe (probe FSQTZ) for the detection of water content and hypochlorite (ClO−) under different excitation wavelengths. The probe itse...

The development of highly specific and ultrasensitive fluorescent probes for tracking basal mitochondrial hypochlorite is very important to unravel its diverse cellular functions in the mitochondria of living cells. In this paper, we have developed a water-soluble, mitochondria-targeted near-inf...

An ‘turn–off’ approach for the detection of ascorbic acid (AA) using 3,3′,5,5′,-tetramethylbenzidine (TMB) as a colorimetric probe is developed. The proposed method is based on the fact that hypochlorite (ClO−) could oxidize TMB to oxidized TMB (oxTMB) along with a blue color and an absorpt...

IntroductionThe shelf life of sodium hypochlorite (NaOCl) is limited, and a previous article showed that there can be a discrepancy between the expected concentration of free available chlorine (FAC) and the actual FAC concentration in NaOCl solutions intended for endodontic irrigation. The curr...
