The non-canonical IκB kinases TANK-binding kinase 1 (TBK1) and inhibitor of nuclear factor kappa-B kinase ε (IKKε) play a key role in insulin-independent pathways that promote energy storage and block adaptive energy expenditure during obesity. Utilizing docking calculations and the x-ray str...

The N-methyl-D-aspartate receptor (NMDAR), a ligand-gated ion channel activated by L-glutamate and glycine, plays a major role in the synaptic plasticity underlying learning and memory. NMDARs are involved in neurodegenerative disorders such as Alzheimer's and Parkinson's disease and N...

Chalcone and chromene derivatives were synthesized in good yield through simple and effective reactions using innocuous solvents such as water and ethanol and high yielding aldol condensations. Generally, the reactions were performed at room temperature, leading to the isolation of highly pure c...

A variety of cardiovascular drugs were treated with 10 equivalent amounts of nitrite in acidic solutions Among 18 drugs, a preparation of bamethan [1-(4-hydroxyphenyl)-1-hydroxy-2-butylaminoethane] showed strikingly high mutagenicity by this treatment toward Salmonella typhimurium TA98 and TA100...

Chronic pain represents one of the most important public health problems, with a great prevalence of comorbidity with depression and cognitive decline. Antidepressants such as duloxetine, a serotonin-norepinephrine reuptake inhibitor, represent an essential part of the therapeutic strategy for c...

BackgroundMajor Depressive Disorder (MDD) is associated with a high rate of inadequate treatment response, which is mainly due to the large inter-individual genetic variability in pharmacokinetic and pharmacodynamic targets of antidepressant drugs. Little is still known about the exact associati...

Stability and toxicity studies for duloxetine and econazole were achieved using individual solutions and their mixtures. Stability of drugs racemates and enantiomers was investigated under abiotic and biotic conditions. Toxicity was evaluated for the first time on Spirodela polyrhiza. EC50 value...

The resolution of racemic 3-(methylamino)-1-(2-thienyl)propan-1-ol 3, a new key intermediate for duloxetine 1, was studied. The conditions were optimized for an industrial-scale resolution of 3 by using (S)-mandelic acid 4 as a resolving agent and 2-butanol containing 2 equimolar amounts of wate...

Studies of acid mine drainage (AMD), a typically extremely acidic environment, can provide opportunities to determine how microorganisms adapt to low pH environments by regulating membrane lipid compositions. In this study, to gain an understanding of microbial pH adaptation mechanisms, we inves...

2-(2,4-Dihydroxyphenyl)thieno-1,3-thiazin-4-ones are a group of new compounds with potential anticancer activity. This type of derivatives was poorly investigated in the area of synthesis and biological activities. In the present study the antiproliferative action of the most active derivative B...

The corrosion inhibition efficiency of 2-amino-4-(2,4-dihydroxyphenyl) quinoline-3-carbonitrile (ADQC) on SAE 1006 steel has been investigated using electrochemical (EIS and Polarization), surface (SEM, EDX and AFM) and quantum chemical calculation methods. Results showed that inhibition efficie...

A series of new 5-substituted 2-(2,4-dihydroxyphenyl)-1,3,4-thiadiazoles has been synthesised and evaluated for their antiproliferative activity. The compounds were prepared by the reaction of the sulphinylbis(2,4-dihydroxythiobenzoyl) (STB) wit hydrazides or carbazates. The panel substitution i...

A series of six coordinate homoleptic and heteroleptic Cr(III) complexes have been formed that incorporate 8-quinolinato ligands. Three classes of complex have been synthesised and characterised: (i) [Cr(Q)3]; (ii) [Cr(Q)2(H2O)2]Cl; (iii) [Cr(Q)(N^N)2](PF6)2 (where Q is a ligand, 8-hydroxyquinol...

Efficient TBHP/R4N+X– promoted hydroaroylations of dialkyl azo-1,2-dicarboxylates with methyl arenes, aldehydes, aryl methanols and arylmethyl chlorides are described. These oxidation/oxygenation and hydroaroylation processes were carried out by tert-butyl hydroperoxide as terminal oxidant/oxyg...

In the present study, a series of 4-(1-aryl-5-chloro-2-oxo-1,2-dihydro-indol-3-ylideneamino)-N-substituted benzene sulfonamides (1–20) was synthesized and screened for their in vitro antimicrobial activity against Gram positive, Gram negative bacterial and fungal strains indicating that compoun...

This study evaluated the physical stability and molecular mobility of a poorly water-soluble amorphous drug, 2-benzyl-5-(4-chlorophenyl)-6-[4-(methylthio)phenyl]-2H-pyridazin-3-one (K-832), adsorbed onto silica mesopores. K-832–Sylysia 740 and K-832–Sylysia 350 formulations, prepared by adsorb...

In the present study a series of 1-substituted-4-(3-chlorophenyl)-[1,2,4] triazolo [4,3-a] quinazolin-5(4H)-ones were synthesized and screened for their H1-antihistaminic activity. The synthesized compounds were characterized by IR, 1H-NMR, mass spectral data and purity of the compounds was dete...

The title compound (22-Thiol) was prepared from the 22-hydroxy derivative via the isothiouronium salt. Using purified enzyme components from bovine adrenocortical mitochondria, 22-Thiol was found to be a potent, competitive inhibitor (Ki = 0.7 μM) of cholesterol side chain cleavage. Spectral st...
