Zasedateleva, Olga A. published the artcilePCR incorporation of dUMPs modified with aromatic hydrocarbon substituents of different hydrophilicities: Synthesis of C5-modified dUTPs and PCR studies using Taq, Tth, Vent (exo-) and Deep Vent (exo-) polymerases, Recommanded Product: 4-Methoxyphenylacetic acid, the main research area is substituent effect DNA duplex preparation; dUMP aromatic hydrocarbon hydrophilicity synthesis PCR dna polymerase; Aromatic hydrocarbon groups; C5-modified dUTPs; Hydrophilicity; Modified DNA; PCR incorporation.

Deoxyuridine triphosphate derivatives (dUTPs) modified at the C5 position of the pyrimidine ring with various aromatic hydrocarbon substituents of different hydrophilicities have been synthesized. The aromatic hydrocarbon substituents were attached to dUTPs via a CH=CH-CH2-NHCO-CH2 linker. The efficiency of the PCR incorporation of modified dUMPs using Taq, Tth, Vent (exo-) and Deep Vent (exo-) polymerases and a model DNA template containing one, two and three adjacent adenine nucleotides at three different sites within the sequence was investigated. For all the polymerases used, the yield of the modified PCR product was significantly increased with increasing hydrophilicity of the aromatic hydrocarbon substituent. In particular, for the above polymerases, the efficiency of the incorporation of dUMPs modified with the most hydrophilic of the studied aromatic hydrocarbon substituents, a 4-hydroxyphenyl residue, was 60-85% of the efficiency of dTMP incorporation. At the same time, the relative efficiencies of the incorporation of dUMPs modified with 2-, 4-methoxyphenyl, Ph and 4-nitrophenyl substituents ranged from 20 to 50% and were 2-18% for the 1-naphthalene and 4-biphenyl groups, which were the most hydrophobic of the studied aromatic hydrocarbon substituents.

Ressmann, Anna K. published the artcileSubstrate-Independent High-Throughput Assay for the Quantification of Aldehydes, Application In Synthesis of 1205-17-0, the main research area is aldehyde quantification high throughput assay aminobenzamidoxime derivative.

The selective and direct reduction of carboxylic acids into the corresponding aldehydes by chem. methods is still a challenging task in synthesis. Several reductive and oxidative chem. methods are known to produce aldehydes, but most of them require expensive reagents, special reaction conditions, are 2-step procedures and often lack chemoselectivity. Nature provides an elegant tool, so called carboxylic acid reductases (CARs) for the direct reduction of carboxylic acids to aldehydes. Discovery as well as engineering of novel CAR enzymes necessitates a robust, product selective high-throughput assay (HTA). The authors report a simple and fast HTA that allows the substrate-independent and chemoselective quantification of aldehydes (irresp. of their chem. structure) and is sensitive to the nM range. The HTA was validated by NMR and GC analyses and in microbial cells by reexamination of the substrate scope of CAR from Nocardia iowensis (CARNi). The results were fully consistent with reported data.

Kong, Duanyang published the artcileFast Carbon Isotope Exchange of Carboxylic Acids Enabled by Organic Photoredox Catalysis, Product Details of C9H10O3, the main research area is carbon labeled carboxylic acid preparation; carboxylic acid carbon isotope exchange photoredox catalyst.

Carbazole/cyanobenzene photocatalysts I (R = 9H-carbazol-9-yl; R1 = CN, PhCH2) promoted the direct isotopic carboxylate exchange of a wide variety of C(sp3) carboxylic acids with 13CO2. Substrates that are not compatible with transition-metal-catalyzed degradation-reconstruction approaches or prone to thermally induced reversible decarboxylation undergo isotopic incorporation at room temperature in short reaction times. The radiolabeling of drug mols. and precursors with [11C]CO2 is also demonstrated.

Schulze-Hennings, U. published the artcileImproving vacuum-UV (VUV) photolysis of organic compounds in water with a phosphor converted xenon excimer lamp emitting at 193 nm, Computed Properties of 117-96-4, the main research area is vacuum UV photolysis organic compound ultrapure water effluent.

A novel vacuum UV excimer lamp emitting light at 193 nm was used to investigate the degradation of organic micropollutants in ultrapure water and wastewater treatment plant (WWTP) effluent. Overall, light at 193 nm proved to be efficient to degrade the investigated micropollutants (diclofenac, diatrizoic acid, sulfamethoxazole). Experiments with WWTP effluent proved the ability of radiation at 193 nm to degrade micropollutants which are hardly removed with commonly used oxidation technologies like ozonation (diatrizoic acid, EDTA, perfluorooctanoic acid, and perfluorooctanesulfonic acid).

Li, Zhen published the artcileThermodynamic and kinetic studies of hydride transfer from Hantzsch ester under the promotion of organic bases, Related Products of isoquinoline, the main research area is hydride transfer kinetics thermodn Hantzsch ester promotion organic base.

Base-promoted hydride transfer (BPHyT), a strategy for the upconversion of hydride donors, was studied here in a three-component system, composed of Hantzsch ester (HEH), acridinium derivatives and organic bases. Based on the thermodn. parameters of hydricity and pKa, we proposed a thermodn. cycle to evaluate the apparent hydricity of HEH/base combinations, as well as the overall driving force of BPHyT. Bronsted-type linear anal. indicated that the base used in BPHyT is much more effective to regulate the reaction kinetics, compared to conventional Bronsted acid or base catalysis. Structure-reactivity relationships showed that the hydride acceptor and the base contribute equally to regulate the kinetics of BPHyT. Kinetic isotope effects suggested that the hydride transfer is involved in the rate-determining step. Reductions of the polar C:C bonds by HEH/base combinations were performed to confirm the feasibility of applying BPHyT in organic synthesis.

Zhang, Xujie published the artcileDesign, synthesis, and mechanism study of dimerized phenylalanine derivatives as novel HIV-1 capsid inhibitors, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is design synthesis mechanism study dimerized phenylalanine; HIV1 capside inhibitor phenylalanine dimer structure activity relationship; Assembly; Capsid; Dimer; HIV-1; Phenylalanine derivatives.

HIV-1 capsid (CA) plays indispensable and multiple roles in the life cycle of HIV-1, become an attractive target in antiviral therapy. Herein, we report the design, synthesis, and mechanism study of a novel series of dimerized phenylalanine derivatives as HIV-1 capsid inhibitors using 2-piperazineone or 2,5-piperazinedione as a linker. The structure-activity relationship (SAR) indicated that dimerized phenylalanines were more potent than monomers of the same chemotype. Further, the inclusion of fluorine substituted phenylalanine and methoxyl substituted aniline was found to be beneficial for antiviral activity. From the synthesized series, I was found to be the most potent compound with an EC50 value of 0.57μM, comparable to II. Interestingly, I demonstrated a slightly higher affinity to the CA monomer than the CA hexamer, commensurate with its more significant effect in the late-stage of the HIV-1 lifecycle. Competitive SPR experiments with peptides from CPSF6 and NUP153 revealed that Q-c4 binds to the interprotomer pocket of hexameric CA as designed. Single-round infection assays showed that I interferes with the HIV-1 life cycle in a dual-stage manner, affecting both pre-and post-integration. Stability assays in human plasma and human liver microsomes indicated that although I has improved stability over II, this kind of inhibitor still requires further optimization. And the results of the online molinspiration software predicted that I has desirable physicochem. properties but some properties still have some violation from the Lipinski rule of five. Overall, the dimerized phenylalanines are promising novel platforms for developing future HIV-1 CA inhibitors with considerable potential for optimization.

Wang, Baolu published the artcileA Borane Lewis Acid in the Secondary Coordination Sphere of a Ni(II) Imido Imparts Distinct C-H Activation Selectivity, Name: 1,3-Dimethoxybenzene, the main research area is aromatic compound carbon hydrogen bond activation kinetics nickel imide; crystal structure boryldiphosphine nickel imido metallacyclic complex.

Two borane-functionalized bidentate phosphine ligands that vary in tether length were prepared to examine cooperative metal-substrate interactions. Ni(0) complexes react with aryl azides at low temperatures to form structurally unusual κ2-(N,N)-N3Ar adducts. Warming these adducts affords products of N2 extrusion and in one case, a Ni-imido compound that is capped by the appended borane. Reactions with 1-azidoadamantane (AdN3) provide a distinct outcome, where a proposed Ni imido intermediate activates the sp2 C-H bonds of arenes, even in the presence of benzylic C-H sites. Combined exptl. and computational mechanistic studies demonstrate that the unique reactivity is a consequence of Lewis-acid-induced polarization of the Ni-NR bond, potentially providing a synthetic strategy for chemoselective reaction engineering.
