A novel multifunctional colorimetric sensor HMBC ((E)-3-((2-hydroxy-3-methoxybenzylidene)amino)benzofuran-2-carboxamide), based on 3-aminobenzofuran-2-carboxamide and 2-hydroxyl-3-methoxylbenzaldehyde, was designed and synthesized. The chemosensor HMBC could sense Co2+, Cu2+, and Zn2+ by color changes from colorless to yellow. Limits of detection (0.38, 0.41, and 1.02 muM) of HMBC for Co2+, Cu2+, and Zn2+ were much lower than the New Jersey Department of Environmental Protection (NJDEP) standard (1.70 muM) for Co2+ and the WHO guidelines (31.5 muM and 76 muM) for Cu2+ and Zn2+. Significantly, HMBC could be applied for the quantification of Co2+, Cu2+, and Zn2+ in real samples. The sensing process of HMBC for Co2+, Cu2+, and Zn2+ was well demonstrated by 1H NMR and UV?Visible titrations, Job plots, theoretical calculations, and ESI-mass spectroscopy.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, name: 3-Methylbenzofuran-2-carboxylic acid, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 24673-56-1, Name is 3-Methylbenzofuran-2-carboxylic acid, molecular formula is C10H8O3

On the basis of our recently resolved first cocrystal structure of Mdm4 in complex with a small molecule inhibitor (PDB ID 3LBJ), we devised an approach for the generation of potential Mdm4 selective ligands. We performed the Ugi four-component reaction (Ugi-4CR) in 96-well plates with an indole fragment, which is specially designed to mimic Trp23, a key amino acid for the interaction between p53 and Mdm4. Generally the reaction yielded mostly precipitates collected by 96-well filter plates. The best hit compound was found to be active and selective for Mdm4 (Ki = 5 muM, 10-fold stronger than Mdm2). This initial hit may serve as the starting point for designing selective p53-Mdm4 inhibitor with higher affinity.

4-Heteroarylidene-2-phenyl-1,3-oxazol-5(4H)-ones were prepared by reactions of hippuric acid with substituted furan-2-carboxaldehydes or furo[b]pyrrole type aldehydes. The reactivity of various furan-2-carboxaldehyde derivatives in this reaction is discussed. The effect of microwave irradiation on some condensation reactions was compared with “classical” conditions. The results show that microwave irradiation shortens the reaction times while affording comparable yields. Elementary analysis, UV, IR and 1D NMR proved the structure of new synthesised compounds. 2D NMR spectroscopic measurements confirmed that the configuration at the carbon-carbon double bond corresponds to the pure E isomers of the products.

Application of 496-41-3, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 496-41-3, Benzofuran-2-carboxylic acid, introducing its new discovery.

A series of 4-benzylpiperidine carboxamides were designed and synthesized, and tested for their dual (serotonin and norepinephrine) reuptake inhibition. The synthesis of 4-benzylpiperidine carboxamides involved two main steps: amidation and substitution. Derivatives with 3 carbon linker displayed better activity than with 2 carbon linker. 4-Biphenyl- and 2-naphthyl-substituted derivatives 7e and 7j showed greater dual reuptake inhibition than standard drug venlafaxine HCl.

In a article，once mentioned of 42933-43-7

Novel substituted 2,3-dihydrobenzofuran-7-carboxamide (DHBF-7-carboxamide) and 2,3-dihydrobenzofuran-3(2H)-one-7-carboxamide (DHBF-3-one-7-carboxamide) derivatives were synthesized and evaluated as inhibitors of poly(ADP-ribose) polymerase-1 (PARP-1). A structure-based design strategy resulted in lead compound 3 (DHBF-7-carboxamide; IC50 = 9.45 muM). To facilitate synthetically feasible derivatives, an alternative core was designed, DHBF-3-one-7-carboxamide (36, IC50 = 16.2 muM). The electrophilic 2-position of this scaffold was accessible for extended modifications. Substituted benzylidene derivatives at the 2-position were found to be the most potent, with 3?,4?-dihydroxybenzylidene 58 (IC50 = 0.531 muM) showing a 30-fold improvement in potency. Various heterocycles attached at the 4?-hydroxyl/4?-amino of the benzylidene moiety resulted in significant improvement in inhibition of PARP-1 activity (e.g., compounds 66-68, 70, 72, and 73; IC50 values from 0.718 to 0.079 muM). Compound 66 showed selective cytotoxicity in BRCA2-deficient DT40 cells. Crystal structures of three inhibitors (compounds (-)-13c, 59, and 65) bound to a multidomain PARP-1 structure were obtained, providing insights into further development of these inhibitors.

The recognition of structural elements (that is, retrons) that signal the application of specific chemical transformations is a key cognitive event in the design of synthetic routes to complex molecules. Reactions that produce compounds without an easily identifiable retron, by way of either substantial structural rearrangement or loss of the atoms required for the reaction to proceed, are significantly more difficult to apply during retrosynthetic planning, yet allow for non-traditional pathways that may facilitate efficient acquisition of the target molecule. We have developed a triflimide (Tf 2 NH)-catalysed rearrangement of N-allylhydrazones that allows for the generation of a sigma bond between two unfunctionalized sp 3 carbons in such a way that no clear retron for the reaction remains. This new traceless bond construction displays a broad substrate profile and should open avenues for synthesizing complex molecules using non-traditional disconnections.

1563-38-8, Name is 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol, belongs to benzofurans compound, is a common compound. Computed Properties of C10H12O2In an article, once mentioned the new application about 1563-38-8.

Agriculture; Biotechnology; Microbiology; Agricultural soil science; Pesticide; Environmental pollution; Bacteria biodegradation immobilized cells carbamates; Psychrophile Carbamates are synthetic pesticides, extensively used throughout the world due to their broad specificity against various insect pests. However, their enormous and inadequate use have made them a potential threat to the environment. At low temperature, degradation of carbamates becomes difficult mainly because of low biological activity. In the present study, we isolated a bacterial strain from a low temperature climate where the N-methylated carbamates are used for crop protection. The bacterium, was identified as Pseudomonas plecoglossicida strain (TA3) by 16S rRNA analysis. Degradation experiments with both free and immobilized cells in minimal salt medium indicated that the strain TA3 utilized carbaryl, carbofuran and aldicarb as both carbon and nitrogen source. TA3 can grow well at 4 C and demonstrated the ability to degrade three carbamates (50 mugml?1) at low temperature. The immobilized cells were found more efficient than their free cells counter parts. Immobilized cells has ability to degrade 100% of carbamates at 30 C while 80% at 4 C but incase of their free cells counter parts the efficiency to degrade carbamates was less which was 60% at 4 C and 80% at 30 C. TA3 free cellsextract also depicted high activity against all the three carbamates even at 4 C indicating a possible enzymatic mechanism of degradation.

Related Products of 4265-25-2, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.4265-25-2, Name is 2-Methylbenzofuran, molecular formula is C9H8O. In a article，once mentioned of 4265-25-2

The catalytic fast pyrolysis of oak over two zeolites (microporous and hierarchical) was investigated in a microfluidized bed reactor (MFBR) at 500 C and as a function of the biomass-to-catalyst ratio. A hierarchical zeolite was produced by desilication with a NaOH solution of a conventional HZSM-5 zeolite. The outlet of the MFBR was connected to a single photoionization mass spectrometer (SPI-MS) for the on-line analysis of volatiles. This on-line analysis method allows studying the dynamics of volatile formation (in real time) and the deactivation of 2 zeolites upon stepwise injections of wood particles. Strikingly, the selectivity of targeted mono-aromatic compounds (quantified by gas chromatography) is doubled after desilication of the zeolite. The coked zeolites were characterized by TEM-EDX, digestion in fluoric acid, MALDI-TOF MS, etc. Three different types of coke are evidenced: (1) coke trapped inside micropores, (2) external coke formed on the outer surface of the crystals and (3) coke precursors deposited in the mesopores. The latter two cokes are much less toxic than the microporous coke. The open mesopores produced after desilication can be seen as “highways” where big molecules (such as levoglucosan) can diffuse to more accessible pore mouths. Br°nsted acid sites present on microporous mouths can be active for the conversion of bigger molecules to small fragments. These fragments diffuse and form aromatics in the micropores (shape selectivity). The mesopores also promote the evacuation of catalytic products, thus enhancing the selectivity of mono-aromatic hydrocarbons. Desilicated zeolites present higher selectivity to mono-aromatics and stability upon coke deposition than microporous zeolites.
