As phase change thermal storage material, sodium acetate trihydrate (CH3COONa·3H2O) exhibits large thermal capacity and holds tremendous promise. However, main problems of undercooling of solidification and phase stratification constrained its application in energy storage. Thus, present work p...
Chemical degradation and spectroscopic evidence lead to the structure I for the dihydrochloride of the antibiotic ferrimycin A1, C4H65O14N10Fe.2HCl. The antibiotic is an acyl derivative of its competitive antagonist and microbial growth factor ferrioxamine B.
The reactions of alkenes and alkynes with ammonium cerium(IV) nitrate ((NH4)2Ce(NO3)6, CAN(IV)) in acetone under reflux gave the corresponding 3-acetyl-4,5-dihydroisoxazole and 3-acetylisoxazole derivatives. In the case of acetophenone, 3-benzoyl-4,5-dihydroisoxazole and 3-benzoylisoxazole deriv...
The impedance of a PVC membrane of a perchlorate ion-selective electrode (PISE) based on a macrocyclic Schiff base barium complex was investigated. The bulk membrane resistances and ion-exchange currents for the PVC membranes of PISEs based on five ion-exchange materials and five plasticizers ar...
The crystal structures of the title compounds have been determined by X-ray diffraction. In the barium compound the cation is coordinated by 10 oxygen atoms, six from the crown ether ring (BaO 2.802–2.846 Å), two water molecules (BaO 2.780, 2.843 Å) and one oxygen atom from a perchlorate io...
The removal of oxyanions found in drinking water sources -perchlorate, nitrate, phosphate, and sulfate- onto magnetic permanently confined micelle arrays (Mag-PCMAs) was studied. We determined the removal efficiency in both competitive and non-competitive environments, as many of these anions ar...
Individual minimum inhibitory and bactericidal concentrations (MIC and MBC) of thiamphenicol (TAP), florfenicol (FFC) and oxytetracycline (OTC) were determined for 49 strains of bacteria isolated from different freshwater fish during disease outbreaks in Brazil. Posteriorly, the in vitro activit...
A method of accelerated solvent extraction coupled with ultra-performance liquid chromatography-fluorescence detection (ASE-UPLC-FLD) for the simultaneous detection of thiamphenicol, florfenicol and florfenicol amine residues in poultry meats (chicken muscle, duck muscle and goose muscle) and po...
Thiamphenicol (TAP) has been widely used in aquaculture to prevent bacterial diseases. However, this drug exhibits toxic side effects on the haemopoietic system. The removal of residual TAP in wastewater in advanced oxidation processes (AOPs) was rarely reported before. In this study, degradatio...
A high-affinity polyclonal antibody was prepared by immunizing animals with haptens FFD and FFM. Under the optimal combination of coating antigen and antibody, an indirect competitive enzyme-linked immunosorbent assay (icELISA) for simultaneous detection of florfenicol and thiamphenicol residues...
Metal complexes of 2-methyl-1H-benzimidazole-5-carboxylic acid hydrazide (4a; L1) and its Schiff base 2-methyl-N-(propan-2-ylidene)-1H-benzimidazole-5-carbohydrazide (5a; L2) with transition metal ions e.g., copper, silver, nickel, iron and manganese were prepared. The complexes formed were 1:1 ...
A series of coumarin-3-carboxamides/hydrazides have been designed and synthesized, all the target compounds were evaluated in vitro for their antifungal activity against Botrytis cinerea, Alternaria solani, Gibberella zeae, Rhizoctorzia solani, Cucumber anthrax and Alternaria leaf spot, some of ...
A series of indole-2-carboxylic acid benzylidene-hydrazides has been identified as a new class of potent apoptosis inducers through a novel cell-based caspase HTS assay. The screening hit, 5-chloro-3-methyl-indole-2-carboxylic acid (4-nitrobenzylidene)-hydrazide (3a), was found to arrest T47D ce...
In view of expanding the structure activity relationship of xanthine oxidase inhibitors, a series of 3-oxo-6-aryl-2,3-dihydropyridazine-4-carbohydrazide/carboxylic acid derivatives were designed by molecular docking and synthesized. All the target compounds were evaluated for their in vitro XO i...
In recent years, indole-indazolyl hydrazide-hydrazone derivatives with strong cell growth inhibition and apoptosis induction characteristics are being strongly screened for their cancer chemo-preventive potential. In the present study, N-methyl and N,N-dimethyl bis(indolyl)hydrazide-hydrazone an...
Three 2-iminofuran ligands 2-(N-2,6-diisopropylphenylformimino)furan (L1), 2-(N-2,6-dimethylphenylformimino)furan (L2) and 2-(N-4-methoxyphenylformimino)furan (L3) were obtained by condensation reactions of the respective anilines with furfural.The η3-allyl Ni(II) cationic complexes 1–3 have b...
The preparation and radiolabeling of 2′-fluoro-2′-deoxy-1-β-d-arabinofuranosyl-5-(2-fluoroethyl)-uracil (FFEAU) with 18F and its evaluation as a probe for imaging herpes simplex virus 1 thymidine kinase (HSV1-tk) gene expression are described. 2′-Fluoro-2′-deoxy-3′,5′-di-O-benzoyl-1-β-d-...
The deoxyfluorination of α-N-phthaloyl cyclobutanone with bis(2-methoxyethyl)aminosulfur trifluoride (Deoxo-Fluor) produced a gem-difluoride product together with a vic-difluoride bearing a cyclopropane ring. In contrast, the deoxyfluorination of the corresponding α-N-phthaloyl cyclopentanone ...
1.1. The metabolism of β-methyl fatty acids has been studied in healthy humans as well as in patients with Refsum's disease who show phytanic acid accumulation. As a test substance 3,6-dimethyl[8-14C]octanoic acid was used. This acid possesses a methyl group in the β-position to the carbo...
The metabolism of 3,6-dimethyloctanoic acid has been studied in guinea-pig kidney slices. The acid is initially degraded by an α-oxidation to 2,5-dimethylheptanoic acid, followed by a β-oxidation to 3-methylvaleric acid. In contrast to 3-methyl-butyric acid (isovaleric acid), 3-methylvaleric a...
