Mesoporous materials have been widely utilized as adsorbents of environmental refractory organics. However, it is a great challenge to synthesize mesoporous adsorbents with controllable pore structures and surface chemical properties. In this study, mesoporous silica-carbon microspheres, aggrega...
The increase in the proportion of microplastics in the environment has intensified the interest in phthalate and microplastic contamination in recent years. In this study, we investigated the response of photosynthetic parameters and the antioxidant system of lettuce to di-n-butyl phthalate (DBP...
A priority pollutant Phthalate Esters (PAEs) are widely used as plasticizers and are responsible mainly for carcinogenicity and endocrine disruption in human. For the bioremediation of PAEs, a psychrotolerant Sphingobium yanoikuyae strain P4, capable of utilizing many phthalates di‑methyl phthal...
The nonphysiological, nonracemic, branched-chain α-acetamido-aminoisobutyric acid was labeled with the carbon isotope 11C with the intention to use it in conjunction with positron emission tomography (PET) to measure the kinetics of amino acid transport in vivo. It was produced by the reaction ...
UDP–GlcN[1-14C]Ac was synthesized in a single enzymatic reaction from [1-14C]acetate and commercially available precursors on both a microcurie (micromole) and a millicurie (millimole) scale. The reaction was catalyzed by the action of acetyl coenzyme A synthetase, inorganic pyrophosphatase, an...
Procedures for the preparation of UDP-N-[1-14C]acetyl-d-glucosamine and UDP-N-[1-14C]acetyl-d-galactosamine with very high specific activities are deseribed. The overall yield based on the amount of [1-14C]acetate used is greater than 80%. The N-acetyl-d-glucosamine-α-1-phosphate used in this s...
Bromo[1-14C]acetyl-CoA has been prepared from CoASH and the N-hydroxysuccinimide ester of bromo[1-14C]acetic acid, and unlabeled bromoacetyl-CoA by reaction of CoASH with bromoacetyl bromide. The products were purified by high-pressure liquid chromatography. Purified bromoacetyl-CoA was characte...
A GLC assay method is described for the determination of 7-trifluoromethyl-1-methyl-5-phenyl-1H-1,5-benzodiaze-pine-2,4-(3H,5H)-dione in the plasma or serum of dogs, rabbits, or humans. After extraction with hexane from acidified plasma or serum, the compound is analyzed by GLC using a flame-ion...
New series of 6-phenyl-2,4-disubstituted pyrimidine-5-carbonitriles namely, 2-substitued thio-6-phenyl-3,4-dihydro-4-oxopyrimidine-5-carbonitriles (5a–d, 6, 7a–d, 8), 2-(4-chlorobenzylthio)-4-chloro-6-phenylpyrimidine-5-carbonitrile (9), 2-(4-chlorobenzylthio)-4-arylthio-6-phenylpyrimidine-5-c...
The PARP-2 selective inhibitor is important for clarifying specific roles of PARP-2 in the pathophysiological process and developing desired drugs with reduced off-target side effects. In this work, a series of novel quinazoline-2,4(1H,3H)-dione derivatives was designed and synthesized to explor...
A series of eight compounds diethyl-3-methyl-5-(6-methyl-2-thioxo-4-phenyl-1,2,3,4-tetrahydropyrimidine-5-carboxamido) thiophene-2,4-dicarboxilate (KM10–17) analogues have been prepared by conventional methods and characterized by IR, Mass, NMR and elemental analysis. In silico docking studies ...
In this manuscript, the chiral separation of novel liver X receptor (LXR) β-selective agonist (±)-1 revealed that (S)-5-(4-(1-methylethoxy)phenyl)-5-methylimidazolidine-2,4-dione (+)-2 was the essential moiety (tail) to express LXR β-selective agonistic activity in a head-to-tail molecular de...
2-Diazo-3-methyl-1-phenyl-5-pyrazolone (2) and 2,4-dihydro-4-[(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)imino]-5-methyl-2-phenyl-3H-pyrazol-3-one (3) were obtained in a one-pot reaction from 3-methyl-1-phenylpyrazol-5-one (1), mesyl azide, and K2CO3 in MeOH or CH2Cl2 solution. NMR, IR and ESI...
The chemical fixation of CO2 is intriguing to eliminate its impact on climate, but harsh reaction conditions are often involved. Herein, we report a new ionic liquid cholinium 2,4-dichlorophenolate which can efficiently promote the conversion of CO2 to quinazoline-2,4(1H,3H)-diones at 1atm CO2 a...
The N-terminal tetrapeptide amide analog of enkephalin (H-Tyr-D-Ala-Gly-Phe-NH2) is approximately equipotent with highly active pentapeptide analogs of enkephalin (and with morphine) in producing analgesia after either intracerebroventricular or intravenous administration. Smaller fragments exhi...
We report the elaboration of new l-Proline functionalized superparamagnetic iron oxide nanoparticles that can act as a new enantioselective organocatalyst. Boc-l-Proline and Fmoc-l-Proline are grafted using two different methodologies on a nanoplateform constituted of 10 nm maghemite (γ-Fe2O3) ...
Proline-functionalized H2N-MIL-101(Al) was synthesized from l- or d-proline-terephthalic acid and used in the catalytic aldol reaction of p-nitrobenzaldehyde with acetone to achieve up to 95% conversion and an ee-value of 29% but in a reversal in enantioselectivity compared to the reaction under...
