Anionic [4+2] annulation of lithiated furoindolones with dimethyl maleate followed by selective demethoxycarbonylation provides an efficient synthetic route to 3-methoxycarbonylcarbazoles. The route has led to the straightforward synthesis of two natural products, namely clausine E, mukonine, and their 4-prenyl analogues. A new route to cyclohepta[d,e,f]carbazole was also uncovered during the investigations.

Synthetic Route of 10242-12-3, 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, 10242-12-3, 5-Nitrobenzofuran-2-carboxylic acid, introducing its new discovery.

A convenient way to introduce aryl functionalization in the 6-position of 4-quinolones is developed via selective bromination and subsequent arylation by Suzuki cross-coupling. Ethyl 4-quinolone 3-carboxylates were subjected to selective bromination at C-6 followed by arylation under microwave irradiation that yielded the desired cross-coupling products within 5 minutes. This approach can expediently be used for library synthesis of the aryl functionalized 4-quinolone derivative, an important class of biologically active compounds.

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

Cell-wall components (cellulose, hemicellulose (oat spelt xylan), lignin (Organosolv)), and model compounds (levoglucosan (an intermediate product of cellulose decomposition) and chlorogenic acid (structurally similar to lignin polymer units)) have been investigated to probe in detail the influence of potassium on their pyrolysis behaviours as well as their uncatalysed decomposition reaction. Cellulose and lignin were pretreated to remove salts and metals by hydrochloric acid, and this dematerialized sample was impregnated with 1% of potassium as potassium acetate. Levoglucosan, xylan and chlorogenic acid were mixed with CH3COOK to introduce 1% K. Characterisation was performed using thermogravimetric analysis (TGA) and differential thermal analysis (DTA). In addition to the TGA pyrolysis, pyrolysis-gas chromatography-mass spectrometry (PY-GC-MS) analysis was introduced to examine reaction products. Potassium-catalysed pyrolysis has a huge influence on the char formation stage and increases the char yields considerably (from 7.7% for raw cellulose to 27.7% for potassium impregnated cellulose; from 5.7% for raw levoglucosan to 20.8% for levoglucosan with CH3COOK added). Major changes in the pyrolytic decomposition pathways were observed for cellulose, levoglucosan and chlorogenic acid. The results for cellulose and levoglucosan are consistent with a base catalysed route in the presence of the potassium salt which promotes complete decomposition of glucosidic units by a heterolytic mechanism and favours its direct depolymerization and fragmentation to low molecular weight components (e.g. acetic acid, formic acid, glyoxal, hydroxyacetaldehyde and acetol). Base catalysed polymerization reactions increase the char yield. Potassium-catalysed lignin pyrolysis is very significant: the temperature of maximum conversion in pyrolysis shifts to lower temperature by 70 K and catalysed polymerization reactions increase the char yield from 37% to 51%. A similar trend is observed for the model compound, chlorogenic acid. The addition of potassium does not produce a dramatic change in the tar product distribution, although its addition to chlorogenic acid promoted the generation of cyclohexane and phenol derivatives. Postulated thermal decomposition schemes for chlorogenic acid are presented.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. COA of Formula: C9H6O3. Introducing a new discovery about 496-41-3, Name is Benzofuran-2-carboxylic acid

Here, we described the structural modification of previously identified mu opioid receptor (MOR) antagonist NAN, a 6alpha-N-7?-indolyl substituted naltrexamine derivative, and its 6beta-N-2?-indolyl substituted analogue INTA by adopting the concept of “bivalent bioisostere”. Three newly prepared opioid ligands, 25 (NBF), 31, and 38, were identified as potent MOR antagonists both in vitro and in vivo. Moreover, these three compounds significantly antagonized DAMGO-induced intracellular calcium flux and displayed varying degrees of inhibition on cAMP production. Furthermore, NBF produced much less significant withdrawal effects than naloxone in morphine-pelleted mice. Molecular modeling studies revealed that these bivalent bioisosteres may adopt similar binding modes in the MOR and the “address” portions of them may have negative or positive allosteric modulation effects on the function of their “message” portions compared with NAN and INTA. Collectively, our successful application of the “bivalent bioisostere concept” identified a promising lead to develop novel therapeutic agents toward opioid use disorder treatments.

The one-pot synthesis of novel 1,4-disubstituted 1,2,3-triazoles from homopropargyl alcohol backbones is described. The key intermediates 2-benzothiophenyl 1a and 2-benzofuranyl 1b substituted homopropargyl alcohols were synthesized starting from their corresponding carboxyaldehyde derivatives. The racemic heteroaryl-substituted homopropargyl alcohol derivatives are successfully resolved to give the corresponding enantiopure acetates and the alcohols with 84-99% ee by applying chemoenzymatic methods using various lipases. Enantiomerically enriched homopropargyl alcohol derivatives were reacted with various aromatic and aliphatic halides and sodium azide via a one-pot synthesis method and novel chiral benzothiophenyltriazoles 3a-9a and benzofuranyltriazoles 3b-9b were constructed without the isolation of potentially unstable organic azide intermediates.

Medical herbs have many bioactive component and they are used in microbial treatment since ancient times. The resistance of pathogens to antibiotics became a critical problem, so researches for novel antimicrobial agents are required. Anacyclus pyrethrum (pellitory, Spanish chamomile or Mount Atlas daisy) is commonly used as a traditional medicine, therefore the antimicrobial activity of the root of this medicinal plant was investigated against 17 bacteria and 1 fungi by using disk diffusion method. The test strains include Bacillus, Enterobacter, Enterococcus, Escherichia, Klebsiella, Listeria, Pseudomonas, Salmonella, Staphylococcus and Candida genera. Besides, chemical composition of this sample was determined by Gas Chromatography-Mass Spectroscopy analysis. The results were presented that A. pyrethrum has antimicrobial activity against all tested microbial species except E. faecalis and S. typhimurium. Eighteen major chemical components were determined, but some composition of this sample is not match with library. For this reason, this medicinal plant contain unknown molecules and this molecules should be analysed NMR spectra for 3D structure determination and identification.

This letter describes the discovery of a novel series of tetrahydroisoquinoline (THIQ)-derived small molecules that potently inhibit both human T-cell migration and super-antigen induced T-cell activation through disruption of the binding of integrin LFA-1 to its receptor, ICAM-1. In addition to excellent in vitro potency, 6q shows good pharmacokinetic properties and its ethyl ester (6t) demonstrates good oral bioavailability in both mouse and rat. Either intravenous administration of 6q or oral administration of its ethyl ester (6t) produced a significant reduction of neutrophil migration in a thioglycollate-induced murine peritonitis model.
