Continuous production of fatty acid ethyl esters (FAEE) from grease trap waste (GTW) in a catalyst-free medium and using pressurized ethanol was evaluated. For this purpose, the lipid fraction was previously separated from GTW, characterized, and used to conduct the reactions, which evaluated th...

ABSTRACTIcosapent ethyl is pure prescription eicosapentaenoic acid (EPA) approved at 4 g/day as an adjunct to diet to reduce triglycerides (TG) in adults with TG ≥500 mg/dL. Elevated high-sensitivity C-reactive protein (hsCRP) is associated with increased cardiovascular (CV) risk. The 12-week A...

Unexpected inhibitory effects against eeAChE could be found for a newly synthesized class of caffeic acid phenethyl ester (CAPE) derivatives. Thus, phenethyl-(E)-3-(3,5-dimethoxy-4-phenethoxyphenyl)-acrylate (Ki = 1.97 ± 0.38 μM, Ki´ = 2.44 ± 0.07 μM) and 4-(2-(((E)-3-(3,4-bis(benzyloxy)phe...

Cinnamic acid derivatives are known antifungal, antimicrobial, antioxidant, and anticancer compounds. We have developed a facile and mild methodology for the synthesis of (E)-cinnamate derivatives using a modified Steglich esterification of (E)-cinnamic acid. Using acetonitrile as the solvent, r...

This study aimed to assess alcohol consumption in a university student population though the combined analysis of the alcohol biomarkers ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEEs) in hair samples. A total of 975 hair samples were analysed for EtG and FAEEs using liquid chromatog...

Residues from wine industry constitute an interesting feedstock for biodiesel in wine-producing countries like Spain. The use of grape seed oil together with bioethanol obtained from wine surplus or distillation of grape skins and stalks in the transesterification reaction results in fatty acid ...

ABSTRACTThis study aimed to obtain ethyl esters (EEs) from macauba pulp crude oil, using heterogeneous-acid catalyst, varying the temperature of (trans)esterification, ethanol-to-oil molar ratio (MR) and catalyst content. Catalyst Amberlyst 15 characterization showed high concentrations of activ...

In present study, surface light scattering (SLS) was used for the simultaneous determination of liquid surface tension and kinematic viscosity of twelve fatty acid esters, including six methyl esters (FAMEs) and six ethyl esters (FAEEs). The SLS apparatus was firstly checked with a reference flu...

Ethyl pyruvate was hydrogenated as a gas-phase reactant over 2.5% Pt/SiO2 premodified with hydroquinidine 4-chlorobenzoate at two concentrations (0.85 and 8.5 mM g−1cat). The sense of enantioselectivity changed as a function of the modifier concentration. At low modifier concentrations, the (S)-...

Toxicity and Carcinogenicity of 2,3-Dibromo-1-propanol in F344/N Rats and B6C3F1 Mice. Eustis, S. L., Haseman, J. K., Mackenzie, W. F., and Abdo, K. M. (1995). Fundam. Appl. Toxicol. 26, 41-50.2,3-Dibromo-1-propanol is a metabolite of the flame retardant tris(2,3-dibromopropyl) phosphate, previo...

This work compares two reaction schemes for preparing 2,3-bis(fattyalkylthio)-1-propanols for further synthetic adaptation as hydrophobic analogs of lung surfactant phosphatidylcholines. An attempt to prepare 2,3-bis(fattyalkylthio)-1-propanols based on the previously published methods of Bell a...

Potassium phthalimide (PPI) is employed as an efficient and effective basic organocatalyst for the one-pot three-component reaction of β-oxoesters with hydroxylamine hydrochloride and various aromatic aldehydes. This cyclocondensation reaction was performed in water as an environmentally benign...

In addition to serving as an f-element ligand and rare-earth method complexing agent, tributyl phosphate is a compound containing core functional groups that mimic those routinely found in degradation products from industrial processes. Because detection of trace quantities of tributyl phosphate...

The use of vapour phase corrosion inhibitors (VPIs) is one of the most effective and convenient methods for preventing corrosion of metallic articles and equipments during storage and transportation. In the present investigation, diethylamine phosphate (DEAP) has been synthesized and its inhibit...

Decarboxylative CC cross-couplings of 2-aminopyrimidine-5-carboxylic acids under a Pd/Ag-based catalytic system opens a new platform for the introduction of diverse C5 substituents. The reaction methods proceeded efficiently with a wide range of the acids and the coupling partners of aryl iodide...

The free fatty acid receptor 1 (FFA1) has emerged as an attractive anti-diabetic target that mediates glucose-stimulated insulin secretion. Several FFA1 agonists have been reported, but many of them possessed somewhat high lipophilicity and/or molecular weight. Herein, we describe the identifica...

A series of novel 1-[5-(4-methoxy-phenyl)-[1,3,4]oxadiazol-2-yl]-piperazine derivatives 8(a–o) were synthesized and characterized by elemental analyses, 1H NMR, 13C NMR and mass spectral studies. The newly synthesized compounds were screened for their anticonvulsant activity against maximal ele...

Two classes of modified analogs of 4-(thiazol-5-yl)benzoic acid-type CK2 inhibitors were designed. The azabenzene analogs, pyridine- and pyridazine-carboxylic acid derivatives, showed potent protein kinase CK2 inhibitory activities [IC50 (CK2α) = 0.014–0.017 μM; IC50 (CK2α′) = 0.0046–0.010...
