Iron(II) complexes of picket-fence-type porphyrins having one of the four pivalamide pickets replaced by a substituent capable of H-bonding have been synthesized as models for oxyhemoglobin. This synthetic approach is analogous to site-directed mutagenesis of the distal residues in oxygen-binding hemoproteins. Rate and equilibrium data for dioxygen binding have been determined to evaluate the effect of the H-bonding substituent and to make comparisons with more passive substituents. The effect of H-bonding on the dioxygen affinity under standard conditions (25 C, toluene solvent, 1,2-dimethylimidazole as axial ligand) is best illustrated by the ca. 10-fold increase observed when one pivalamide substituent of picket-fence porphyrin is replaced by a phenylurea substituent. Other substituents influence dioxygen adduct stability in a variety of ways to reveal that even with an apparently straightforward systematic approach, there can be considerable difficulty in partitioning the various factors that influence O2 affinity. This applies to both model compounds and mutant proteins.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Quality Control of 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1563-38-8, Name is 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol, molecular formula is C10H12O2

This study examined the photodecomposition of carbofuran, a carbamate pesticide with high oral toxicity. Rate constants are measured for the pesticide in aqueous solution and in the presence of various samples of dissolved organic matter (DOM). Kinetic experiments are monitored with HPLC, while reaction products are determined using HPLC, GC-MS, and 1H NMR: mechanisms are proposed for the first three steps of the reaction. It was found that the photodecomposition proceeds via first-order reaction kinetics and that the presence of various DOM samples inhibits the photolysis reaction of carbofuran. This phenomenon can be correlated to the magnitude of the binding interaction between carbofuran and DOM. Finally, techniques such as GC-MS and 1H NMR are used to identify the photodecomposition products. The first three steps of the reaction are defined. In the first step of the reaction, the carbamate group is cleaved from the molecule. The furan moiety is opened in the second step producing a substituted catechol with a tert-butyl alcohol group as the substituent at the number three carbon. This molecule then undergoes a dehydration reaction to form an alkene side group from the tert-butyl alcohol side group.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Douchi is a traditional fermented soybean food with many beneficial health effects. The aim of this study was to determine the in vitro apoptosis-inducing effect of the volatile components of Douchi (VCD) and to examine the relationship between anticancer effects and VCD. After treatment with 0.4, 0.8, and 1.6 mg/mL VCD for 48 h, the proliferation of human nasopharyngeal carcinoma CNE-1 cells was inhibited, and treatment with 1.6 mg/mL VCD had the highest inhibitory effect(84.6%). Treatment with 0.4 and 0.8 mg/mL VCD also showed good inhibitory effects with the apoptosis rates of 29.7%and 55.6%, respectively. The flow cytometry results showed that 36.2% of the 1.6 mg/mL VCD treated CNE-1 cells in the sub-G1 phase. Reversed transcription-polymerase chain reaction (RT-PCR) analysis indicated that VCD could significantly induce apoptosis in CNE-1 cancer cells (P < 0.05) by upregulating cysteine-aspartic acid protease (caspase)-3, caspase-8,caspase-9, Bax, p53, p21, E2F1, p73 and IkappaB-alpha expression and by downregulating Bcl-2, Bcl-xL, human inhibitor of apoptosis protein (HIAP)-1, HIAP-2 and NF-kappaB mRNA expression in a dose-dependent manner. VCD contained 63 chemical compounds that could potentially cause apoptosis in CNE-1 cells. These results showed that VCD had in vitro apoptosisinducing effects in CNE-1 cells, and this effect was ascribed to the complex chemical composition of VCD. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

We previously reported the discovery of pyrimido-pyrrolo-quinoxalinedione (PPQ) inhibitors of the cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel and showed their efficacy in an organ culture model of polycystic kidney disease (PKD) (J. Med. Chem. 2009, 52, 6447-6455). Here, we report related benzopyrimido-pyrrolo-oxazinedione (BPO) CFTR inhibitors. To establish structure-activity relationships and select lead compound(s) with improved potency, metabolic stability, and aqueous solubility compared to the most potent prior compound 8 (PPQ-102, IC50 ? 90 nM), we synthesized 16 PPQ analogues and 11 BPO analogues. The analogues were efficiently synthesized in 5-6 steps and 11-61% overall yield. Modification of 8 by bromine substitution at the 5-position of the furan ring, replacement of the secondary amine with an ether bridge, and carboxylation, gave 6-(5-bromofuran-2-yl)-7,9-dimethyl-8,10-dioxo-11-phenyl-7,8,9, 10-tetrahydro-6H-benzo[b]pyrimido [4?,5?:3,4]pyrrolo [1,2-d][1,4]oxazine-2-carboxylic acid 42 (BPO-27), which fully inhibited CFTR with IC50 ? 8 nM and, compared to 8, had >10-fold greater metabolic stability and much greater polarity/aqueous solubility. In an embryonic kidney culture model of PKD, 42 prevented cyst growth with IC 50 ? 100 nM. Benzopyrimido-pyrrolo-oxazinediones such as 42 are potential development candidates for antisecretory therapy of PKD.

Synthetic Route of 4265-25-2, 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, 4265-25-2, 2-Methylbenzofuran, introducing its new discovery.

The decomposition behaviour of diglycidylether of bisphenol A (DGEBA) cured with 4-methyl tetrahydrophthalic anhydride (MeHHPA) or dapsone (DDS) in near-critical water was investigated. Reaction mechanisms based homolysis of the bonds in the polymer followed by saturation of the resulting radicals by hydrogen abstraction from the water were discussed. The decomposition rate increased with the increase of reaction time and temperature. Due to the presence of ester groups in the DGEBA/MeHHPA/BDMA main chains, they were broken at the beginning of the decomposition process, while it was more difficult to decompose the DGEBA/DDS system, due to the introduced benzene ring. The GC-MS proved that the two resin systems were decomposed to small molecular compounds. The experimental results indicated that the decomposition mechanisms of the two resin systems might involve cyclization reactions and chain-end scission in near-critical water. The two resin systems tended to form oligomers with longer molecular chains at lower temperatures with the random scission. Meanwhile, a first-order kinetic model was implemented for the decomposition reaction process. The results showed that the calculated activation energy (Ea) of the two resin systems was 266.7 kJ mol-1 and 170.7 kJ mol-1, respectively.

The synthesis of trifluoroethylamines as amide bond mimics is an interesting topic in current research. They are well known tools in pharmaceutical and agrochemical industry. Other methods described in literature are often restricted to few substrates. We herein report a new synthetic approach towards this class of substances. First, the trimethylaluminium- promoted generation of a trifluoromethyl-ketimine from the corresponding trifluoromethyl ketone and an aniline derivative was investigated. Next, the ketimine was converted into the trifluoroethylamines in a one-pot reaction by simple addition of borane-methyl sulfide complex.
