In heterogeneous catalysis, the catalyst is in a different phase from the reactants. SDS of cas: 4265-16-1, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 4265-16-1, name is Benzo[b]furan-2-carboxaldehyde. In an article，Which mentioned a new discovery about 4265-16-1

Summary: Purpose The human tumour suppressor protein p53 is mutated in nearly half of human tumours and most mutant proteins have single amino acid changes. Several drugs including the quinazoline derivative 1 (CP-31398) have been reported to restore p53 activity in mutant cells. The side chain of 1 contains a styryl linkage that compromises its stability and we wished to explore the activity of analogues containing more stable side chains. Methods Reactivation of p53 function was measured by flow cytometry as the ability to potentiate radiation-induced G1-phase cell cycle arrest and by western blotting to determine expression of p21WAF1. DNA binding was measured by competition with ethidium and preliminary pharmacological and xenograft studies were carried out. Results Screening of analogues for potentiation of radiation-induced G1-phase cell cycle arrest using NZOV11, an ovarian tumour cell line containing a p53R248Q mutation, demonstrated that the (2-benzofuranyl)-quinazoline derivative 5 was among the most active of the analogues. Compound 5 showed similar effects in several other p53 mutant human tumour cell lines but not in a p53 null cell line. 5 also potentiated p21WAF1 expression induced by radiation. DNA binding affinity was measured and found to correlate with p53 reactivation activity. Plasma concentrations of 5 in mice were sufficient to suggest in vivo activity and a small induced tumour growth delay (7 days) of NZM4 melanoma xenografts was observed. Conclusion Compound 5 restores p53-like function to a human tumour cells lines expressing a variety of mutant p53 proteins, thus providing a basis for the design of further new drugs.

The answer is in thermodynamics and kinetics.In a document type is Review, and a compound is mentioned, 496-41-3, Benzofuran-2-carboxylic acid, introducing its new discovery.

A considerable progress has been made to understand the mechanisms of biodegradation of 2,4-dichlorophenoxyacetic acid (2,4-D). 2,4-D biodegradation pathway has been elucidated in many microorganisms including Cupriavidus necator JMP134 (previously known as Wautersia eutropha, Ralstonia eutropha and Alcaligenes eutrophus) and Pseudomonas strains. It generally involves the side chain removal of 2,4-D by alpha-ketoglutarate-dependent 2,4-D dioxygenase (tfdA) to form 2,4-dichlorophenol (2,4-DCP); hydroxylation of 2,4-DCP by 2,4-DCP hydroxylase (tfdB) to form dichlorocatechol; ortho or meta cleavage of dichlorocatechol by chlorocatechol 1,2-dioxygenase (tfdC) to form 2,4-dichloro-cis,cis-muconate; conversion of 2,4-dichloro-cis,cis-muconate to 2-chlorodienelactone by chloromuconate cycloisomerase (tfdD); conversion of 2-chlorodienelactone to 2-chloromaleylacetate by chlorodienelactone hydrolase (tfdE) and, finally, conversion of 2-chloromaleylacetate to 3-oxoadepate via maleylacetate by chloromaleylacetate reductase and maleylacetate reductase (tfdF), respectively, which is funnelled to the tricarboxylic acid cycle. The latest review on microbial breakdown of 2,4-D, other halogenated aromatic pesticides, and related compounds was compiled by Haggblom, however, a considerable progress has been made in this area of research since then. Thus, this review focuses on the recent advancement on 2,4-D biodegradation, the enzymes, and genes involved and their biotechlogical implications.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1563-38-8, 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol, introducing its new discovery.

The haptens 4-[[(2,3-dihydro-2,2-dimethyl-7-benzofuranyloxy)carbonyl]- amino]butanoic acid (BFNB) and 6-[((2,3-dihydro-2,2-dimethyl-7-benzofuranyloxy)- carbonylamino]hexanoic acid (BFNH) were synthesized and then used to develop a rapid, specific and sensitive ELISA method to determine residues of the pesticide carbofuran in a variety of matrices. A hybridoma cell line (5D3) producing anti-carbofuran monoclonal antibodies (MAbs) was also established. Based on the MAbs in combination with the heterologous hapten BFNH coupled to either horseradish peroxidase (HRP) or ovalbumin (OVA), four ELISAs (formats I-IV) for the quantification of carbofuran were developed and compared. Among them, the optimized format II (the conjugate-coated direct competitive ELISA) showed the best characteristics, with an IC50 value of 18.49 ng/mL, a limit of detection of 0.11 ng/mL and the shortest assay time (1 h). This ELISA method was then applied to the determinations of carbofuran in environmental water, soil and food samples. The relative standard deviations (R.S.D.s) ranged from 1.8% to 21.3% and the mean recoveries were 104.6%, 108.3%, 106.3% and 100.1% for water, soil, lettuce and cabbage, respectively. Thus, the ELISA method of format II exhibited the potential to develop commercial ELISA kits for a rapid detection of carbofuran for human health and environmental safety.

Chemistry is traditionally divided into organic and inorganic chemistry. Formula: C9H8O, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 4265-25-2

Two batches of smoked, semi-hard (ripened for 45 d) San Simon da Costa cow’s milk cheeses with Protected Designation of Origin were used to investigate the chemical, biochemical, and sensorial parameters that may be affected by modified-atmosphere packaging. Cheeses were packaged for 45 d as follows: vacuum packaging, packaging in 100% N2, packaging in a gas mixture of 20% CO2/80% N2, and packaging in a gas mixture of 50% CO2/50% N2. The San Simon da Costa cheeses were characterized by high contents of lactic, oxalic, and citric organic acids. The main free amino acids found were isoleucine, phenylalanine, serine, valine, lysine, and glutamic acid, and the most abundant volatile compounds included ethanol, diacetyl, 2-butanol, isopropyl alcohol, furfural, acetaldehyde, 2-butanone, acetone, and 2-methylfuran. Modified atmospheres appeared to alter the ripening processes by affecting lipolysis, as indicated by the lower concentrations of butyric and propionic acids compared with control cheeses. In addition, modified-atmosphere packaging altered the proteolysis processes, yielding higher amounts of branched-chain alcohols. The results revealed that storage under modified atmosphere contributes to the accumulation of several compounds probably derived from smoke, including aldehydes such as 2-furancarboxaldehyde (furfural), alcohols such as 2-methoxyphenol (guaiacol), ketones such as 2-cyclopenten-1-one, and esters such as methyl furancarboxylate, which were negatively correlated with flavor. Vacuum packaging was the most useful technique in terms of preserving the sensory quality of San Simon da Costa Protected Designation of Origin cheeses. Considering the current demands for packaged portions of food at the distribution and retail levels and the potential health risks associated with some smoke-derived compounds usually present in some smoked foods, the results obtained in this study may be of special interest to the cheese industry.

Electric Literature of 4265-25-2, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 4265-25-2, molcular formula is C9H8O, introducing its new discovery.

A concept is suggested for explaining deviations of certain CH acids from the linear Bronsted relationship. The major attention is given to ion-dipole interaction between the molecules of a polar aprotic solvent and dissolved carbanions. The concept is based on correcting the experimental pKa values by eliminating the contributions from electrostatic solvation using data on the ionization constants of CH acids in the gas phase (DeltaHg). By the examples of acid dissociation of methyl CH bonds under conditions of established equilibrium in DMSO and kinetic data for deuterium exchange in a solution of an alkali metal amide in liquid ammonia, it was shown that for a series of compounds PhM(CH3)n-1 and M(CH3)n (M = N, O, P, S, CO), and also for some other methyl derivatives all kinds of deviations from the Bronsted relationship are realized (those originating from specific conditions of stabilization of the transition state in the course of reaction; those due to electrostatic solvation of the equilibrium carbanions; and the deviations resulting from combined effect of the kinetic and equilibrium factors). Also, the Bronsted relationships were obtained for ionization of CH acid series covering compounds with aliphatic, quasiaromatic, and aromatic CH bonds (the deuterium exchange was performed in liquid ammonia without a catalyst). The Bronsted coefficient alpha 0.65 in this relationship suggests a higher degree of deprotonation of the CH bond in the transition state as compared to the catalytic exchange (alpha 0.3). The revealed difference is due to the different effect of electronic factors: In the catalytic deuterium exchange, the major contribution to the activation free energy (logk D) is made by the resonance effects of substituents, whereas in the noncatalytic deuterium exchange the inductive effect prevails.
