Isatin inhibits the invasion and metastasis of SH-SY5Y neuroblastoma cells in vitro and in vivo

Indoline-2,3-dione or indole-1H-2,3-dione, commonly known as isatin, is found in plants of genus Isatin and in Couropita guianancis aubl, and inhibits tumor cell proliferation through its antioxidant effects. The present study analyzed the effect of isatin on the malignant phenotype of neuroblastoma cells, and reported that isatin significantly inhibited neuroblastoma cell proliferation, invasion and migration in vitro in a dose-dependent manner, and distant metastasis in tumor-bearing mice. Mechanistically, isatin inhibited lysine-specific histone demethylase (LSD)1 and reversed the blockade on p53, thereby activating the apoptotic pathway. The inhibitory effect of isatin on LSD1 may be mediated via direct binding and molecular docking or indirectly through the TGF beta/ERK/NF-kappa B signaling pathway. Isatin also alleviated the renal and hepatic toxicity of cyclophosphamide in the tumor-bearing mice, indicating its potential as a candidate drug as well as an adjuvant for treating metastatic neuroblastoma.

One-pot synthesis of 2-substituted thieno[3,2-b]indoles from 3-aminothiophene-2-carboxylates through in situ generated 3-aminothiophenes

A convenient protocol for one-pot synthesis of thieno[3,2-b]indoles, bearing aromatic, thien-2-yl or styryl fragments at C-2 position, from easily accessible 5-substituted 3-aminothiophene-2-carboxylates using the Fischer indolization reaction, was developed during this study. Two main steps of this approach are the saponification of the starting 3-aminoesters with sodium hydroxide and next treatment of the crude 3-aminoacids sodium salts with arylhydrazines in glacial acetic acid solution. The latter step includes in situ decarboxylation of the freed 3-aminothiophene-2-caboxylic acids to the 3-aminothiophenes and their acid promoted reaction with arylhydrazines to initially form arylhydrazones of 5-substituted thiophene-3(2H)-ones, which smoothly cause indolization to afford the desired thieno[3,2-b] indoles.

Insights into thermal hydrolyzed sludge liquor – Identification of plant-growth-promoting compounds

This study proposes a new path to utilize thermal hydrolyzed sludge (TH sludge) as fertilizer given high value chemical compounds that can promote plant growth were identified in the liquid fraction of TH sludge (TH liquor). Together with micro- and macro-nutrients released/synthesized during thermal hydrolysis, the feasibility of using TH liquor as organic fertilizer was evaluated. Besides high contents of N, P and K, total free amino acids (FAAs) and plant-growth-promoting FAAs (including glutamic acid, leucine and cystine) also presented in high concentration (4.98-6.48 and 1.12-2.73 g/100 g) in the TH liquor. For the first time, phytohormone compound, indole-3-acetic acid, was observed and the content was the highest in TH liquor with 165 degrees C treatment (165 degrees C TH liquor). Meantime, 165 degrees C TH liquor did not have negative impact on the growth of soil microbes, and this product, instead, demonstrated stimulating effect on the plant growth. These results suggest that 165 degrees C TH liquor has a great potential to be an organic fertilizer. The remaining solids of TH sludge could be converted to valuable biochar. The holistic approach of using TH liquor as organic fertilizer and producing biochar could realize nearly zero-waste discharge in sludge management.

Construction of Polycyclic Indole Derivatives via Multiple Aryne Reactions with Azaheptafulvenes

[GRAPHICS] An efficient [8 + 2]/aryl-ene tandem reaction between azaheptafulvenes and arynes has been developed, leading to the formation of cyclohepta[b]indoles in a single step with good yield. In addition, employment of excess arynes provides a [8 + 2]/aryl-ene /[6 + 2] tandem reaction to synthesize polycyclic oxacyclohepta[b]indoles. This is the first time that azaheptafulvenes have been employed in tandem reactions with arynes.

Discovery of novel indole derivatives that inhibit NEDDylation and MAPK pathways against gastric cancer MGC803 cells

A series of novel indole derivatives were synthesized and evaluated for their antiproliferative activity against three selected cancer cell lines (MGC803, EC-109 and PC-3). Among these analogues, 2-(5-methoxy-1H-indol-1-yl)-N-(4-methoxybenzyl)-N-(3,4,5-trimethoxyphenyeacetamide (V7) showed the best inhibitory activity against MGC803 cells with an IC50 value of 1.59 mu M. Cellular mechanisms elucidated that V7 inhibited colony formation, induced apoptosis and arrested cell cycle at G2/M phase. Importantly, indole analogue V7 inhibited NEDDy-lation pathway and MAPK pathway against MGC803 cells.

Synthetic Route of 480-41-1, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 480-41-1 is helpful to your research.

Covalent or Non-Covalent? A Mechanistic Insight into the Enantioselective Bronsted Acid Catalyzed Dearomatization of Indoles with Allenamides

The reaction mechanism of the enantioselective Bronsted acid catalyzed dearomatization of C(2),C(3)-disubstituted indoles with allenamides is investigated by means of density functional theory (DFT) calculations and ESI-MS analysis. The first step of the process (rate-determining step) is the formation of a covalent adduct between allenamide and the chiral organo-promoter. The resulting chiral alpha-amino allylic phosphate undergoes dearomative condensation with indoles. In the first step, the indole moiety remains bonded to the catalyst through strong hydrogen contacts. It can take on two different orientations that make the Re or Si prochiral face available to the subsequent electrophilic attack of allenamide. The attack on the indole faces originates two reaction paths leading to different stereoisomeric products, which differ in the configuration of the new stereocenter at the C3-indole position.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 147-94-4 help many people in the next few years. COA of Formula: C9H13N3O5.

Thermochemical Properties and Dehydrogenation Thermodynamics of Indole Derivates

Indole and methylindole are heterocyclic aromatics, which can be hydrogenated and used for hydrogen storage. A huge advantage of heterocyclic components compared to homocyclic aromatics is the lower enthalpy of reaction for hydrogen release by dehydrogenation. In this study, thermochemical properties of indole and 2-methylindole and its partially and fully hydrogenated derivatives have been determined. Hydrogenation of indoles is a two-step reaction, which is highly influenced by reaction thermodynamics. High precision combustion calorimetry was used to measure enthalpies of formation of indole derivatives. The gas-phase enthalpies of formation were derived with the help of vapor pressure measurements. The high-level quantum-chemical methods were used to establish consistency of the experimental data. The standard molar thermodynamic functions of formation (enthalpy, entropy, and Gibbs energy) of indole derivatives were derived. The results showed that the partially hydrogenated species, 2-methylindoline, tends to dehydrogenate easily under hydrogen release conditions. Thus, indoline is only expected in trace amounts in the respective reaction mixture.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 72-14-0, you can contact me at any time and look forward to more communication. Name: Sulfathiazole.

Organophotocatalytic dearomatization of indoles, pyrroles and benzo(thio)furans via a Giese-type transformation

Dearomatisation of indoles allows efficient access to indolines, but often is incompatible with electron-withdrawing substituents. Here a photoredox Giese-type dearomatisation of indoles yields 2,3-disubstituted indolines bearing electron-withdrawing groups. Accessing fascinating organic and biological significant indolines via dearomatization of indoles represents one of the most efficient approaches. However, it has been difficult for the dearomatization of the electron deficient indoles. Here we report the studies leading to developing a photoredox mediated Giese-type transformation strategy for the dearomatization of the indoles. The reaction has been implemented for chemoselectively breaking indolyl C=C bonds embedded in the aromatic system. The synthetic power of this strategy has been demonstrated by using structurally diverse indoles bearing common electron-withdrawing groups including (thio)ester, amide, ketone, nitrile and even aromatics at either C-2 or C-3 positions and ubiquitous carboxylic acids as radical coupling partner with high trans-stereoselectivity (>20:1 dr). This manifold can also be applied to other aromatic heterocycles including pyrroles, benzofurans and benzothiophenes. Furthermore, enantioselective dearomatization of indoles has been achieved by a chiral camphorsultam auxiliary with high diastereoselectivity.
