Alcohols with different structures are used frequently in hygiene products and cosmetics. It is desirable to classify these alcohols to evaluate their potential harmful effects using less costly methods. In this study, five different types of alcohol are classified using five QCM sensors with di...

Multidrug efflux transporters are a plague in the antibiotic resistance mechanisms as they confer the capacity of bacteria to evade most of current therapies. Although these transporters were initially discovered as proton-motive driven pumps, another class of multidrug efflux transporters has e...

Novel hybrids N-(4-phenoxybenzyl)aniline were designed, synthesized, and evaluated for their potential AChE inhibitory activity along with antioxidant potential. The inhibitory potential (IC50) of synthesized analogs was evaluated against human cholinesterases (hAChE and hBChE) using Ellman’s m...

This work describes an asymmetric functionalization of the pyrrole ring of an indole structure with (2,2,2-trifluoro)ethylamine moiety allowing for general access to two novel classes of trifluoromethyl-containing indoles. We found that under the Friedel–Crafts reaction conditions (S)-N-tert-bu...

A novel quinoline-functionalized hexahomotrioxacalix[3]arene L was synthesized via Click chemistry and its chemosensing properties with various metal ions were investigated. The chemosensor L exhibited a high selectivity for Fe3+ with little interference from other environmentally and biological...

A series of analogues of potent antiviral perylene nucleoside dUY11 with methylthiomethyl (MTM), azidomethyl (AZM) and HO-C1–4-alkyl-1,2,3-triazol-1,4-diyl groups at 3′-O-position as well as the two products of copper-free alkyne-azide cycloaddition of the AZM derivative were prepared and eval...

A solid-phase radioiodination technique for ω-iodophenyl fatty acids using ammonium sulfate is described. The radioiodinations are (1) regioselective, (2) high in yield (95%), (3) short in reaction time (1 h) and (4) capable of yielding high specific activity products although at lower yields. ...

Reversed phase liquid chromatography–atmospheric pressure chemical ionization mass spectrometry (RP-HPLC/MS-APCI) was used to identify and quantify triacylglycerols (TAGs) having odd-numbered ω-phenylalkanoic acids from seeds of the flower plant Dracunculus vulgaris, and TAGs from the bacteriu...

Several closely related long-chain ω-phenylalkanoic and ω-phenylalkenoic acids occur in the seed lipids of genera of the subfamily Aroideae of the Araceae. One, 13-phenyltridecanoic acid, is a major component. This is the first report of these acids in plant lipids. Their presence in only one ...

In the present paper we describe the first synthesis and evaluation of a novel Mn (II) complex (DTPA-PPDA Mn (II)) which contains a C-15 fatty acid moiety that has high affinity to the heart muscle. The complexation energy of DTPA-PPDA Mn (II) evaluated by quantum chemistry methodology indicates...

Benzotriazole and aldehydes react reversibly to give addition products: in the presence of amines and other NH-compounds water can be eliminated to form products of type Bt-CHR-NR′R″. The latter are versatile intermediates for the preparation of primary, secondary, and tertiary amines and in t...

A novel and very sensitive potentiometric sensor with excellent electrochemical properties containing olanzapine- tungstophosphate ion pair as modifier was fabricated for the analysis of olanzapine in real samples. The modified electrode showed Nernstian slope of 59.2 mV decade−1 for olanzapine ...

A feasibility simulation study evaluates the utilization of the physical–chemical solvent Sulfolane plus Methyl di-ethanol amine (MDEA) plus H2O (Sulfinol-M), to replace the aqueous amine solvent (MDEA) currently used in the sour-gas treatment unit of the large-scale Khangiran gas processing pl...

Natural gas issued from well production has to be treated to remove acid gases (CO2 and H2S) and sulfur compounds so that it meets transport requirements and sale gas specifications. Two great families of solvents are used for this kind of gas treatment: chemical and physical solvents. Ilam gas ...

Dihydroagarofuran sesquiterpenes, which were isolated from Tripterygium wilfordii Hook fil. var. regelii Makino and Euonymus sieboldianus Blume, showed inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate (TPA). Triptogelin A-...

New sesquiterpene esters, triptogelin A-1, A-2, A-3, A-4 and B-1, have been isolated from the achenes of Tripterygium wilfordii var. regelii and their structures established by chemical and spectroscopic means.

Inhibiting low-density lipoprotein (LDL) oxidation and cellular lipid accumulation to reduce foam cell formation plays a key role in preventing atherosclerosis. Casein hydrolysate (66%

The mechanism of action of food-derived angiotensin-I-converting enzyme (ACE) inhibitory peptides has not been completely elucidated. In the present study, ion-exchange chromatography, gel filtration chromatography, reverse phase-high performance liquid chromatography, and liquid chromatography-...

Glucosamine and ACE inhibitory peptides were produced from five mushrooms by sulfuric acid hydrolysis. Straw mushroom, hydrolysed at 100 °C for 4.03 h by 5.67 mol L−1 sulfuric acid, had the highest glucosamine yield (56.81 mg/g), while oyster mushroom hydrolysate presented the maximum ACE inhib...

In this research, ovalbumin (OOW), one of the major components in ostrich egg white, was purified by anion exchange chromatography. Then, the purified OOW was subjected to alkaline hydrolysis (0.25 M NaOH) at 40 °C for 2–10 h. The best angiotensin I-converting enzyme (ACE) inhibitory activity ...
