Indoles are an important class of heterocyclic compounds with diverse biological activity. This is mainly because of the unique ability of the compounds to mimic the structure of peptides and bind reversibly to proteins. Therefore, efficient methodologies for the synthesis of various indole derivatives are always of interest to both organic and medicinal chemists. Although there have been several reports for the synthesis of 2-substituted indoles, most of the methods have several disadvantages such as expensive reagents, toxic solvents, harsh reaction conditions, tedious workup procedures and poor yield of products. In the present work, a simple and efficient method for the synthesis of a novel 2-substituted indole has been developed.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 54827-17-7. Recommanded Product: 54827-17-7.

This study explored the effect of methyl-indole on pancreatic cancer cell viability and investigated the mechanism involved. The viability of pancreatic cells showed a significant suppression on treatment with methyl-indole in dose-based manner. Treatment with 5 mu M methyl-indole suppressed Capan-1 cell viability to 23%. The viability of Aspc-1 cells was reduced to 20% and those of MIApaCa-2 cells to 18% by 5 mu M methyl-indole. The apoptotic proportion of Capan-1 cells was 67%, while as those of Aspc-1 and MIApaCa-2 cells increased to 72 and 77%, respectively, on treatment with 5 mu M methyl-indole. The level of P13K, p-Tyr, p-Crkl and p-Akt was inhibited in the cells by methyl-indole. Moreover, methyl-indole also suppressed zinc-finger protein, X-linked mRNA and protein expression in tested cells. In summary, methyl-indole exhibits anti-proliferative effect on pancreatic cancer cells and induces apoptosis. It targeted ZFX expression and down-regulated P13K/AKT pathway in pancreatic cancer cells. Therefore, methyl-indole acts as therapeutic agent for pancreatic cancer and may be studied further.

This work aims to use fly ash and the organic template of tetrapropyl ammonium bromide (TPABr) to synthesize the catalyst carrier of HZSM-5 and prepare the catalyst of CuO/HZSM-5 for catalytic wet air oxidation (CWAO) of phenol, quinoline and indole in aqueous solution. The carrier and the catalyst were characterized by x-ray diffraction (XRD), X-ray fluorescence spectroscopy (XRF) and Brunauer-Emmett-Teller (BET) tests and the results indicate HZSM-5 zeolite and CuO/HZSM-5 catalyst have been successfully synthesized. The specific surface area of catalysts with copper loading from 0 to 15% decreased from 310.1 m(2) g(-1) to 253.8 m(2) g(-1). The results of catalyst performance showed that the catalyst of CuO/HZSM-5 with copper loading of 10% has the best removal effect on the mixed aqueous solution containing phenol, quinoline and indole. When the total concentrations of phenol, quinoline and indole are 200 mg.l(-1) (namely 120 mg phenoll(-1), 60 mg quinolinel(-1) and 20 mg indolel(-1)), the catalyst with the copper loading of 10% can remove these organic matters with 100% efficiency after reaction for 4 h at 200 degrees C and the COD removal rate is more than 75%. Under the same experimental conditions, if the reaction temperature drops to 120 degrees C, the COD removal rate will rise to 86.2%. The CWAO experiments showed the optimum reaction temperature range for the Cu-10% catalyst is from 120 degrees C to 150 degrees C.

Neisseria meningtidis is responsible for causing meningococcal meningitis along with acute septicaemia in human beings. Functional genomics strategies proved cruciality of certain genes/proteins in Neisseria meningitidis pathogenesis. During the present studies, three important Neisseria meningitidis proteins i.e., Dead box RNA-Helicase, Polyribonucleotide nucleotidyl-transferase PNPase and Ribonuclease-III were targeted for homology modeling and protein-ligand docking studies not only to detelinine their three dimensional architectures but also to identify their potential novel inhibitors. The Biscoumarin, malonitrile and indole derivatives showed the best inhibitory mode against all of the three enzymes. Since, these enzymes are assembled in Gram-negative bacteria to foul’ RNA degradosome assembly therefore their inhibition will definitely shut off the degradosome assembly and ultimately the decay of RNA, which is an essential life process. This is the first ever structural investigation of these drug targets along with identification of potential novel drug candidates. We believe that these small chemical compounds will be proved as better drugs and will provide an excellent barrier towards Neisseria meningitidis pathogenesis.

A series of indole-1-carboxylic acid aryl esters was synthesized with indole and substituted phenols as raw materials. The structures of the target compounds were validated by IR and H-1-NMR spectroscopies. The inhibitory activities of the target compounds and their potencies against marine fouling organisms were investigated. The results showed that the target compounds had significant inhibitory effects on the growth of three seaweeds: Isochrysis galbana, Platymonas subcordiformis, and Navicula, and the target compounds also had excellent inhibition on the survival of barnacle larvae. The substituent structure-activity relationships revealed a significant effect on biological inhibition activity: Compounds substituted by electron-withdrawing groups had greater bioactivities than those containing electron-donating groups. Release rate of antifoulant and marine field tests indicated the final compounds had an outstanding antifouling potency against marine fouling organisms.

The coal pyrolysis wastewater (CPW) contributed to aquatic environment contamination with amount of aromatic pollutants, and the research on joint toxicity of the mixture of aromatic compounds was vital for environmental protection. By using Tetrahymena thermophile as non-target organism, the joint toxicity of typical nonpolar narcotics and polar narcotics in CPW was investigated. The results demonstrated that the nonpolar narcotics exerted chronic and reversible toxicity by hydrophobicity-based membrane perturbation, while polar narcotics performed acute toxicity by irreversible damage of cells. As the most hydrophobic nonpolar narcotics, indole and naphthalene caused the highest joint toxicity in 24 h with the lowest EC50mix (24.93 mg/L). For phenolic compounds, the combination of p-cresol and p-nitrophenol also showed the top toxicity (EC50mix = 10.9 mg/L) with relation to high hydrophobicity, and the joint toxicity was obviously stronger and more acute than that of nonpolar narcotics. Furthermore, by studying the joint toxicity of nonpolar narcotics and polar narcotics, the hydrophobicity-based membrane perturbation was the first step of toxicity effects, and afterwards the acute toxicity induced by electrophilic polar substituents of phenols dominated joint toxicity afterwards. This toxicity investigation was critical for understanding universal and specific effects of CPW to aquatic organisms.

The reaction of 2-amino-1,4-naphthoquinones with ninhydrin at 50-60 degrees C in acetic acid leads to 4b,11b-dihydroxy-4b,5-dihydrobenzo[f]indeno[1,2-b]indole-6,11,12(11bH)-triones. The products were isolated as hydrates, and, when heated in DMSO with methanesulfonic acid or in acetic acid in the presence of sulfuric acid, they converted into 13-R-benzo[f]isochromeno[4,3-b]indole-5,7,12(13H)-triones. The rate of the conversion of 4b,11b-dihydroxy-4b,5-dihydrobenzo[f]indeno[1,2-b]indole-6,11,12(11bH)-triones to 13-R-benzo[f]isochromeno[4,3-b]indole-5,7,12(13H)-triones in solutions of sulfuric acid in acetic acid is linearly related to the Hammett acidity function.
