The chromatographic and electrophoretic behaviour of aryloxyalkyl ammonium compounds, such as 1-alkylpiperidinium bromides, pyridinium bromides, benzyl-dimethylammonium bromides and trimethylammonium bromides, were studied. The group constant for the aromatic, alkyl and basic parts of the molecu...

1.1. The effect of a cation active quaternary ammonium salt, domiphen bromide (dodecyldimethyl(2-phenoxyethyl)ammonium bromide), on the enzymic hydrolysis of certain N-l-aminoacyl-2-naphthylamines and p-nitrophenyl phosphate was investigated. The enzymes studied included commercial trypsin, chym...

A practical direct preparation of tert-butyl esters from 2-tert-butoxypyridine has been developed. This system features the use of boron trifluoride·diethyl etherate in toluene solvent to rapidly achieve the reaction at room temperature. Using this reaction protocol, a variety of tert-butyl est...

In this paper, 41 hybrid compounds containing diaryl-1,5-diazole and morpholine structures acting as dual COX-2/5-LOX inhibitors have been designed, synthesized and biologically evaluated. Most of them showed potent antiproliferative activities and COX-2/5-LOX inhibitory in vitro. Among them, co...

A series of 82 5-aryl-2-thio-1,3,4-oxadiazole derivatives were screened for their anti-mycobacterial activities against Mycobacterium tuberculosis H37Rv. The synthesized compounds 30–37 appeared to be the most active derivatives exhibiting more than 90% inhibition of mycobacterial growth at 12....

A series of [(2-pyrimidinylthio)acetyl]benzenesulfonamides were designed and synthesized. Their binding affinities as inhibitors of several recombinant human carbonic anhydrase (CA) isozymes were determined by isothermal titration calorimetry (ITC) and thermal shift assay (TSA). A group of compo...

A series of cobalt(II) complexes supported by 8-(methylthio)-2-(R-pyrazolyl)quinoline (R = H, CH3, and Ph) ligands (3a–3e) were synthesized and characterized by elemental, FT-IR, and UV–visible analyses. X-ray diffraction analysis revealed that complexes 3b and 3c adopted distorted square pyra...

The new functionalized hydroxymethylphosphonic and methylenebis(phosphonic) acids are synthesized via reaction of tris(trimethylsilyl) phosphite and N-formyl derivatives of five-membered N-heterocycles in the presence of trimethylsilyl triflate.

PI3K/Akt/mTOR signaling pathway plays an important role in cancer cell growth and survival. In this study, a new class of molecules with skeleton of 4-phenyl-2H-benzo[b] [1,4]oxazin-3(4H)-one were designed and synthesized targeting this pathway. Bioassays showed that, among all the molecules, 8d...

Orexins play an important role in sleep/wake regulation, and orexin receptor antagonists are a focus of novel therapy for the treatment of insomnia. We identified 27e (TASP0428980) as a potent dual orexin receptor antagonist through the systematic modification of our original designed lead A. We...

This paper reports the results on the study of a set of synthesized bifunctional 3-hydroxy-4-pyridinones chelators as potential aluminium sequestering agents. They were N-functionalized with alkyl-amino, -carboxylic and –(amino-carboxylic) groups, envisaging the improvement of the Al3+ sequeste...

Herein, we report Fe3O4@O2PO2(CH2)2NH3+CF3CO2− as a novel and reusable ionically tagged nanomagnetic catalyst. It was characterized by several techniques including Fourier transform infrared (FT-IR) spectroscopy, thermo gravimetric analysis/differential thermal analysis (TGA/DTA), scanning elect...

The asymmetric oxidative coupling reaction between 2-naphthol or binaphthol derivatives and 3-hydroxy-2-naphthoate derivatives with the copper(I)-(S)-(−)-isopropylidenebis(4-phenyl-2-oxazoline) catalyst was carried out. The reaction proceeded in a highly cross-coupling selective manner (≤99.7%)...

Henry's Law constants (H) and octanol–air partition coefficients (KOA) for polycyclic aromatic hydrocarbons (PAHs) and selected nitrogen-, oxygen- and sulfur-containing derivatives have been computed using the COSMO-RS method between −5 and 40 °C in 5 °C intervals. The accuracy of the es...

The application of the aromatic Mannich reaction to α,β-unsaturated aldehydes, affords a series of new diaminoalkyl naphthols, by a convenient solventless reaction, starting from inexpensive and easily available starting materials. The absolute configurations of the products obtained are attri...

The solvent resistance capacity of Pseudomonas putida S12 was applied by using the organism as a host for biocatalysis and through cloning and expressing solvent resistant pump genes into Escherichia coli. P. putida S12 expressing toluene ortho mononooxygenase (TOM-Green) was used for 1-naphthol...

The photogalvanic cells based on Naphthol Green B sensitizer-Fructose reductant-Sodium Lauryl Sulphate surfactant has been studied in natural sunlight. The cell has been found workable in natural sunlight with greatly enhanced optimum cell performance. The 1159.2 μW power, 4500 μA short-circui...
