The development of a solution-phase approach to the rapid, parallel synthesis of highly functionalized piperazinones in only four steps starting from N-Boc-iminodiacetic acid is detailed. The efforts represent the extension of the solution-phase synthesis of combinatorial libraries from N-Boc-iminodiacetic acid to non-amide-based libraries where simple liquid-liquid extractions are employed to purify all reaction products. This methodology was applied to the synthesis of a diverse 150-member library with substituents in three positions of the piperazinone core. Screening results from a luciferase reporter assay indicate that a number of library members are novel repressors of LEF-1/beta-catenin-mediated transcription, and may be effective agents against colorectal tumors. Two secondary libraries (100 members each) designed from these lead structures were synthesized and screened, providing additional active agents and insight into key structure-activity relationships in the series. These compounds represent only the second class of small molecules which repress transcription of reporter genes containing LEF-1 responsive elements, and the first group not based on DNA minor-groove-binding agents.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 24673-56-1, you can also check out more blogs about24673-56-1

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, COA of Formula: C8H6O3, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 16859-59-9, Name is 3-Hydroxyisobenzofuran-1(3H)-one, molecular formula is C8H6O3

A new synthetic route for the conversion of substituted 3-hydroxyphthalides into the corresponding isoquinolin-1(2H)-one was established. This method can be applied to the preparation of isoquinolin-1(2H)-ones with electron-withdrawing groups that are relatively difficult to synthesize by conventional procedures.

Application of 89877-62-3, 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, 89877-62-3, 3-Oxo-1,3-dihydroisobenzofuran-5-carbonitrile, introducing its new discovery.

Tyrosyl-DNA phosphodiesterase I (Tdp1) plays a key role in the repair of damaged DNA resulting from the topoisomerase I (Top1) inhibitor camptothecin and a variety of other DNA-damaging anticancer agents. This report documents the design, synthesis, and evaluation of new indenoisoquinolines that are dual inhibitors of both Tdp1 and Top1. Enzyme inhibitory data and cytotoxicity data from human cancer cell cultures were used to establish structure-activity relationships. The potencies of the indenoisoquinolines against Tdp1 ranged from 5 muM to 111 muM, which places the more active compounds among the most potent known inhibitors of this target. The cytotoxicity mean graph midpoints ranged from 0.02 to 2.34 muM. Dual Tdp1-Top1 inhibitors are of interest because the Top1 and Tdp1 inhibitory activities could theoretically work synergistically to create more effective anticancer agents.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. HPLC of Formula: C9H8O. Introducing a new discovery about 4265-25-2, Name is 2-Methylbenzofuran

This study combines the results of experimental measurements and theoretical computations to investigate the initial steps in the oxidation of dibenzo-. p-dioxin (DD). The aim is to discover new pathways leading to the formation of toxic species in combustion systems, as well as compounds that may act as precursors for polychlorinated dibenzo-. p-dioxins and polychlorinated dibenzofurans (PCDD/F). The experiments were performed in a tubular reactor equipped with sampling systems for condensable and gaseous products. The reaction conditions were characterised by a residence time of 5. s and a fuel equivalence ratio of 0.12. We investigated the effect of temperature (400-800C) on the type and the yield of the oxidative products, trapped in a cartridge, and gases collected in tedlar bags for subsequent FTIR analyses. The analyses of VOC, performed on a high resolution gas chromatograph-triple quadrupole mass spectrometer (HRGC-QQQMS), identified 2-methylbenzofuran and 3-hydro-2-methylenebenzofuran as the initial products. This has been confirmed by injection of authentic standards and the application of collision induced dissociation (CID) that fragmented the isolated parent ions into specific product ions affording the identification of parent species. The oxidative decomposition of DD initiated at around 450C, with the evolution of VOC peaking at between 650 and 700C. In excess of 750C, all VOC were completely oxidised. The potential energy surface (PES), based on the density functional theory (DFT) of B3LYP, mapped the initial steps involved in the oxidation of DD, and yielded a detailed reaction scheme for the onset of oxidation of DD that results in the formation of 2-methylbenzofuran and 3-hydro-2-methylenebenzofuran. Initial oxidation of DD is most likely to commence via addition of the singlet oxygen molecule and the subsequent facile formation of the propagating OH radical.

Application of 4265-25-2, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4265-25-2, Name is 2-Methylbenzofuran, molecular formula is C9H8O. In a Article，once mentioned of 4265-25-2

ZSM-5 zeolite is an efficient catalyst for both biomass deoxygenation and polyolefins cracking in pyrolysis process. In this study, wood-plastic composite (WPC), composed mainly of woody materials and thermoplastic polymers, was pyrolyzed using Py-GC/MS over phosphorus-modified HZSM-5 (P-HZSM-5) with varying P loadings (from 0 to 10 wt.%). The catalysts were prepared by wet impregnation method and characterized by XRF, XRD and NH3-TPD. The effects of pyrolysis temperature, time, heating rate, catalyst to WPC ratio and P loadings on the hydrocarbon distribution of WPC pyrolysis were studied. Pyrolysis conditions have significant effects on hydrocarbon distribution. Parent HZSM-5 facilitated aromatics formation, while P-HZSM-5 favored the formation of light aliphatic hydrocarbons (C4-C12). The yields of C4-C12 increased first with rising pyrolysis temperature from 450 to 550 C, then decreased over 550 C. Similarly, C4-C12 yields increased during the pyrolysis time from 15 to 30 s and decreased with the further prolonged time. A low heating rate (0.002 C/ms) favored the formation of light aliphatic hydrocarbons, while high heating rates (>0.2 C/ms) favored the formation of aromatics. Increasing catalyst to WPC ratio augmented aromatic selectivity. Hydrocarbon distribution strongly depended on the catalyst’s acidity, adjusted by varying P loading in P-HZSM-5. The highest yield of C4-C12 was obtained while using P-HZSM-5 with P loading of 3.5 wt.%.
